Geothermal heating and cooling systems are much more efficient than standard HVAC systems and can help you save money. It’s especially true if you live in North Texas. You already know summer brings extreme heat and winter can have long periods of freezing weather. This can jack up your heating and cooling bills something fierce.f93e4a78-c2e7-4273-c2d0-e8b19195674d

Unlike most heat pumps, geothermal heating and cooling systems use the earth as a conduit to cool or heat a closed loop water system. This, in turn, runs your home’s AC, heating, and hot water bypass. These systems are 45 percent more energy efficient than other options in the marketplace today. Because of this, the government is offering a 30 percent federal tax credit for anyone who installs a new geothermal system in their home.

The 30 percent federal tax credit will cover the cost of the new unit, plus the costs of all installation and labor. To be eligible for the credit, you have to have a new geothermal heating and cooling system installed in the home you live in. It’s not available for any systems placed in rentals or secondary vacation homes. The new heating and cooling system must meet the Energy Star requirements that are in effect at the time the system is purchased.

Currently, heat pumps that are certified by the unit’s manufacturer are eligible for the tax credit and should be installed by a licensed contractor. It is important to have an engineered system for your specific home needs.34e6cec2-2b00-48d3-f703-e2240722a8023

While a geothermal system may require a larger upfront investment than regular HVAC systems, they will pay for themselves with the utility savings over the years. Plus, a system lasts up to four times longer than a standard conventional AC system, which saves even more money the first time you don’t have to replace the AC equipment.

Options For Geothermal Ground Loop Installations

Monday 25 May 2015 22:31
Written by

Geothermal heat pumps use the constant temperature of the ground to exchange heat between the inside and outside of your house. It pulls heat from the ground to heat your home in the winter, and pulls heat from your house and leaves it in the ground in summer.

A geothermal system can reach efficiencies of up to 600 percent. Compare that to even the most energy efficient furnace, which can't convert all of its energy into heat for your home. Air source heat pumps typically achieve heating efficiencies of up to 250 percent, though that’s still far less than a geothermal heat pump.

The primary component of a geothermal heat pump system is the ground loop, which is either open or closed. In a closed loop system, the pipe typically runs horizontally, between 4 and 6 feet deep, or vertically between 100 and 400 feet. In North Texas the average depth required for a good heat transfer is 250 feet per well loop. The pipes are filled with an environmentally safe antifreeze and water solution that acts as a heat exchanger. In the less-common open loop system, surface water is used as a heat transfer medium.

When considering your options for geothermal installations, it’s important to factor in your location. Your property type will determine which type of ground loop you'll use. Your geothermal HVAC contractor will look at the geology, hydrology and landscape to decide.

The composition of your soil and rock affects the rate at which heat is transferred. For example, soil with good heat transfer properties will require less piping. Areas with shallow soil or lots of rock may require vertical ground loops.

The availability of ground or surface water can help determine what type of ground loop to use. Certain bodies of surface water can be used as a source of water for an open-loop system, or in a closed-loop system as the location for coils of piping. Ground water can also be used as a water source for open-loop systems, provided the water quality is suitable.

Seasonal Geothermal Maintenance Is Essential To Year Round Comfort And Efficiency

Monday 25 May 2015 22:30
Written by

Has your geothermal heat pump system gotten its yearly maintenance check? Even though it's a "heat pump," it's already working hard this summer. But if you missed your regular springtime maintenance call, you don't want the thing to struggle and overwork itself trying to keep your house cool. Geothermal systems are capable of cooling (and heating) your home very efficiently. They transfer heat energy into the ground rather than burning fuel. Geothermal heat pumps use the earth’s constant temperature to exchange heat between your home’s interior and the outside. The primary component of a geothermal system is the ground loop, which is either open or closed. In a closed loop system, the pipe is typically between 4 and 6 feet deep and horizontally, or vertically at a depth of between 100 and 400 feet. The pipes are filled with an environmentally safe antifreeze and water solution that acts as a heat exchanger. In the less-common open loop system, surface water is used as a heat transfer medium.

Seasonal geothermal maintenance



This heat extraction and release process repeats until your home is cool. To stay cool, it’s wise to call in a heating and cooling pro twice a year at the start of the cooling and heating seasons. The technician will ensure proper airflow, mechanical function, and system performance by the following methods:
  • Thoroughly clean the indoor and outdoor units. This includes removing dirt build-up and blockages that consistently occur at the heat-exchanger coils and blowers.
  • Measure blower air speed. Airflow that’s too slow reduces heat exchange efficiency. Airflow that’s too fast wastes electricity, and produces more noise than necessary.
  • Electrical components are inspected for function, tight connections and wear and tear.
  • All moving parts are lubricated.
  • The system is checked for leaks. If there are leaks, the technician will discuss repair options with you.
  • Once the geothermal system is clean, airflow optimized, and no refrigerant leaks are detected, accurate refrigerant levels may be measured.

Geothermal Cooling And Heating — Year Round Comfort And Savings

Monday 25 May 2015 22:26
Written by

Geothermal cooling and heating provides North Texas homeowners with an extremely efficient and money-saving method of maintaining home comfort in all seasons. Heat pumps can attain astonishingly high levels of efficiency (300 to 600 percent, in some cases) while producing no greenhouse gases or other harmful emissions. Geothermal units are clean and quiet and can save homeowners up to 70 percent on their seasonal heating and cooling bills.

Heat pumps achieve these high-quality results through their unique mode of operation. In general, geothermal heat pumps operate much the same as a traditional heat pump. Both use water or a compressed, high-pressure liquid coolant to capture heat and move it either into or out of your home to maintain seasonally appropriate temperatures. While a conventional heat pump uses heat from the air, a geothermal model uses heat generated naturally below the surface of the ground or a body of water.

A few feet under the ground, temperatures are always about a consistently mild temperature, somewhere around 50 – 60 degrees, no matter what the temperature is on the surface. Geothermal heat pumps move and exchange heat through a series of pipes buried in the ground at this consistent-temperature depth. These units do not have to work harder to extract heat from cold outside air, which can cause air-source systems to use more electricity. Instead, they shift heat back and forth from a source that stays about the same temperature all the time. This leads to highly efficient operation, better levels of indoor comfort and reduced power consumption.

Geothermal systems require more of an upfront investment versus conventional air conditioning systems. There are three main areas of savings where home owners will quickly recoup this investment and then begin to see a positive payback:
  • A 30% tax credit on the initial installation.
  • Up to 70% savings annually on utility bills required to operate your AC system.
  • Geothermal heat pumps last up to 3 times longer than conventional equipment, because the equipment is indoors instead of outside, and is not subject to the outdoor elements and have ideal operating conditions with little stress on the equipment.
However, they can be as much as 50 percent more efficient than even high-efficiency heating and cooling systems. The dramatically increased efficiency and comfort they provide can make the investment in geothermal cooling and heating a wise long-term option.

Your Geothermal System And Ceiling Fans: A Dynamic Duo

Monday 25 May 2015 22:24
Written by

You know your geothermal system can keep you cool in the summer and warm in the winter. And you've got your ceiling fans running every summer to help keep the temperature down. But did you know that you can use ceiling fans to your advantage in the winter as well?

Many people avoid using ceiling fans when the temperature drops outside because of the cool breeze they create. But, just reverse the direction the blades spin — clockwise, instead of counterclockwise — it creates an updraft that sends warm air from the geothermal system that has collected near the ceiling back down into the living space, and helps your geothermal system work more efficiently.

It’s important to keep the fan spinning on the lowest setting in the winter so the updraft moves slowly. Otherwise, it could create cooling air movement that would defeat the fan’s usefulness for geothermal home heating.

Homes with vaulted ceilings or open stairways benefit the most from ceiling fans in the winter. Since hot air naturally rises, homes with lots of open space overhead experience uneven heating and higher energy bills. The updraft from a fan on a vaulted ceiling sends warm air back down to the edges of the room.

Install a ceiling fan at the top of an open stairway to help mix the air more evenly. It keeps the upper story from becoming overly warm. Even if you don’t have vaulted ceilings or open stairways, ceiling fans can still reduce your geothermal heating costs and help decrease condensation buildup on window panes that can lead to moisture damage.

Running a ceiling fan costs mere pennies per day — even less if you choose an Energy Star rated fan. Installing and using ceiling fans properly in your home can help you save up to 10 percent on your heating bills while helping your home feel more comfortable as well.

Geothermal Heat Pump Buying Guide

Monday 25 May 2015 22:21
Written by

Geothermal heat pumps, refrigerators, and air conditioners have one thing in common: they remove heat from one place and transfer it to a different place. Geothermal heat pumps let you control the temperature in your home year-round, because the cycle is reversible — you can take heat out of your house in the summer, and put it into the ground or a standing water supply, like a pond. Or you can take the heat out of the ground in the winter, and have it transferred into your home.

When installed correctly, geothermal heat pumps can deliver two to four times more heat to a home than the actual energy they use to operate, which makes them very efficient. Overall benefits include:
  • Decreased utility bills (25 to 70 percent less than conventional HVAC systems)
  • Less maintenance
  • Controlled climate, more comfort year-round
  • Lower emissions
Two main types of heat pumps are on the market today: air source and geothermal. Air source pumps take heat from an air source, whether inside your home or outside. A geothermal pump will draw its heat energy from a different source, whether the earth, ground water, or another water source.

Efficiency should be a top priority when you’re looking into purchasing a heat pump. Energy Star-labeled systems operate 8 to 20 percent more efficiently than traditional HVAC systems. However, the size of the system is a key factor in the final price.

Your system needs to be sized by an HVAC profession, but the general rule of thumb is you will need one "ton" of geothermal heat pump for every 400 square feet of home you want to serve. For example, if your home is 2,000 square feet, you will need a 5-ton heat pump. (This isn’t a ton in the traditional sense, but rather a term that originally referred to how much ice was needed to cool a certain amount of air.)

Tax Credits Are Another Benefit Of Geothermal Heat Pumps

Monday 25 May 2015 22:19
Written by

crawford_12_4_12Geothermal heat pumps may be the best way to condition homes in our climate. We have long, hot summers and periods throughout the winter that can be exceptionally cold. A geothermal system is capable of providing efficient conditioning for both extremes.

Instead of using the air to harvest or dispel heat, geothermal systems use underground resources, where temperatures are stable and moderate. So efficient are these systems that the federal government is offering a 30 percent tax credit for homeowners who install these systems before the end of 2016. This credit covers primary and secondary residences, although it does not extend to rental properties.

The primary reason the government is offering this credit is to help homeowners lower their energy consumption and offset the higher installation costs of these systems. Geothermal heat pumps use up to 60 percent less energy to run than air-source heat pumps, which is why the tax credit is so generous. A heat pump in our region is an efficient HVAC appliance, but when the pump can use stable underground resources rather than volatile air temperatures, this appliance offers even better energy savings.

Not only does a geothermal system provide excellent energy efficiency, it's also a durable heat pump. The underground loop can last up to 50 years or more and the indoor air handler up to 25, with routine maintenance. Geothermal systems also do not have exterior condensers, which frees up yard space and eliminates the noise in your yard.

In order to qualify for the tax credit, the geothermal heat pump has to have earned the Energy Star designation. There is no upper limit on the amount that can be claimed for either the cost of the equipment or its installation. The tax credit may not cover adjustments to your ducts, however, unless the adjustments impact the overall energy efficiency of the system.

Geothermal Heating and Cooling in Dallas – Is It Right for You?

Monday 25 May 2015 22:17
Written by

02_26_13A geothermal heating and cooling system is an extremely efficient and economical alternative to traditional natural gas powered or electric powered furnaces /air handlers and air conditioners. When evaluating the merits of the many available types of geothermal heating and cooling in Dallas, keep in mind the following benefits you'll enjoy with a geothermal comfort system.
  • Exceptional efficiency: Geothermal systems are extremely efficient, providing an extraordinary 300 to 400 percent efficiency level. They produce three or four units of heat for each unit of electricity consumed. This can be achieved because heat pumps do not generate heat. Instead, they capture and displace energy allowing the ground beneath us to serve as the energy source to cool or heat water which serves as the source of energy for the homes comfort system. Sounds confusing but it really is a simple process.
  • Flexibility: Geothermal heating and cooling is appropriate for any climate and can be adapted for use in most any setting, urban, suburban, or rural.
  • Low cost of operation: Geothermal heating and cooling systems can slash your monthly energy bills by as much as 70 percent. You will find that the initial investment in a geothermal installation system may cost up to 2 times the amount of a conventional system, but the 30% federal tax credit on the complete installation combined with the monthly savings on your utility bills means you'll recover the initial costs in 3-7 years depending on your total usage.
  • Lower lifetime costs: Geothermal heating and cooling systems are sturdy and reliable. With regularly scheduled, twice year maintenance, a geothermal heat pump system will last 25 years or longer. That is 2-3 times longer than a conventional furnace or condensing unit. Why? Because the geothermal system sit inside your home in a mechanical area that is not subjected to the outdoor elements and corrosive conditions. They need little maintenance and repair to keep them running.
  • Peace and quiet: Geothermal heat pumps produce very little noise when they operate. They work quietly and are not irritating or disruptive to your household. So there are no unsightly large condensing units lined outside your home or noisy while you are trying to enjoy the outdoors.
  • Environmentally friendly: Geothermal systems do not burn fuel, so they do not produce greenhouse gases or dangerous exhaust fumes such as carbon monoxide. Their efficiency level means they use less electricity than other sources, which reduces overall demand for power from your local electric company.

Geothermal Energy: Eco-Friendly, Consistent and Cost-Effective

Monday 25 May 2015 22:15
Written by

04_18_13Geothermal energy provides Dallas area homeowners with an efficient, cost effective and environmentally sound source of home heating and cooling.

A geothermal system takes advantage of the fact that the ground maintains remarkable temperature consistency, absorbing much of the solar energy from the sun’s rays as they hit the ground. A properly installed geothermal energy system uses a buried earth loop to convert this free energy into affordable and energy-efficient central heating and cooling.

In the heating cycle, the geothermal heat pump uses the earth loop (carrying a water/antifreeze mix) to extract collected solar heat from underground. After the system removes heat from the loop, it’s distributed into your home via your air ducts. For geothermal cooling, the heating process is reversed to create cool, conditioned air for the home. Instead of removing heat from the ground, heat is pulled from the air in your home and either returned to the earth loop and the ground, or used to preheat water in your storage water-heating tank.

Geothermal energy offers heating and cooling customers several very attractive benefits, including:
  • Extremely high efficiency: Geothermal heating systems can be highly efficient, often returning three or four units of heating per each unit of electricity consumed by the system. The fact that geothermal systems capture and move heat readily available underground (or underwater) rather than burning fuel to generate heat accounts for this type of efficiency.
  • Consistency and flexibility: Geothermal energy systems can be used in any climate and can be adapted for use in almost any residential setting, from urban to suburban to rural.
  • Low cost of operation: With geothermal heating and cooling, you can knock your monthly energy bills down by as much as 70 percent. Though geothermal can be expensive to install, the monthly savings alone can pay for the system by about the halfway point of its useful life span. Further reducing the costs, the federal government, through 2016, is offering a 30 percent energy tax credit for qualifying geothermal systems.
  • Environmentally friendly: Geothermal systems do not burn fuel to produce heat, so they do not produce greenhouse gases or harmful exhaust gases such as carbon monoxide. Because they are so energy efficient, they use less electricity, which reduces demand on your local utility company.
  • Inexpensive water. Geothermal heat pumps are often equipped with the ability to use warmth removed from your home in the summer for low-cost water heating.

With Geothermal Energy, Make Sure Your Heat Pump Works Well

Monday 25 May 2015 22:12
Written by

07_02_13Geothermal energy is a clean, efficient and economical source for residential cooling and heating. Keeping your geothermal heat pump working at its top level of performance requires regular maintenance and repair of problems as they occur. In cooperation with your geothermal specialist, you can take effective steps to keep your heat pump working like it should.

What you can do if a problem arises
  • Check the power supply. Make sure the heat pump is plugged in and receiving electrical power.
  • Check air filters and coils. Dirty filters and coils can cause problems with the system's airflow and head pressures. Clean the coils and change the air filters if they are dirty.
  • Look at temperature settings. Make sure the thermostat has been set to an appropriate temperature and mode (heating or cooling) for the season.
  • Check for physical problems. Carefully inspect the system for leaks, disconnected wiring or physical problems that could cause malfunctions.
What your geothermal energy systems expert can do

Your geothermal system professional has the necessary expertise and equipment to test for and repair technical issues. He will look for problems such as:
  • Reduced effectiveness and efficiency: Could be an issue with restricted system airflow. Check and change air filter.
  • No cooling: Cooling levels can be affected by low refrigerant charge, scale build-up in the heat exchanger, restricted metering devices, or a defective reversing valve. The system thermostat may need to be moved to another location so that it senses indoor temperature changes more accurately.
  • High indoor humidity: This could be caused by too much airflow or an oversized system. Your technician can adjust the fan motor speed to help resolve the problem.
  • Problems with the loop system. The use of geothermal energy for heating and cooling requires a functioning loop system where heat capture and release occurs in the ground (or water). Your technician will make sure the loop pumps are working properly and that there is appropriate pressure in the loop system.

Geothermal Energy Is Clean and Quiet, and Can Also Be Cool

Monday 25 May 2015 22:05
Written by

positive-performanceIn Texas, geothermal energy provides a reliable and economical source of comfort for almost year-round home cooling requirements. A geothermal energy system provides exceptional cooling at a monthly cost that is usually much lower than other forms of cooling. The overall benefits of geothermal energy make it an attractive option for Dallas area home and business owners.

Basics of geothermal energy

Geothermal cooling and heating systems are based on heat pump technology. Instead of generating heating or cooling, the heat pump system captures heat and moves it in or out of your home. In a ground-source system, this is accomplished in a series of pipes buried in the ground at a depth where the temperature stays about 50-55 degrees all year long. Water-source systems are based on a similar concept, but the pipes are placed in a lake, pond, aquifer, or other body of water at a depth where the temperatures stay consistent.

A water/antifreeze solution (or in some cases refrigerant) flowing through the pipes is the medium of heat transfer. This solution either captures heat from inside your home and disperses it into the ground or water, which cools your home, or captures heat from the ground or water source and brings it into your home, where heat pump technology converts it into heating.

Installing a geothermal energy system requires careful consideration of the area where the underground or underwater pipes will be installed. For example, there must be enough ground space for the trenching and digging required to place the pipes. A horizontal system requires a wide flat area, while a vertical system requires deep holes for installing the heat transfer pipes.

Geothermal energy benefits

As a source of home cooling, a geothermal energy system provides multiple benefits that make it a good choice.
  • Very high efficiency: Geothermal heat pumps are extremely efficient, which means they provide indoor cooling at a lower price than other systems. Savings of 25 to 50 percent on monthly cooling bills are common. A geothermal system can often pay for itself in savings alone by about the halfway point of its expected lifespan. Plus, there's a 30 percent tax credit for qualifying geothermal systems.
  • Quiet operation: Geothermal cooling systems run very quietly compared to traditional heating and cooling systems.
  • Environmentally clean: Geothermal energy systems do not burn fuel, so they don't produce exhaust fumes or additional greenhouse gases. Their efficiency means they use less electricity than other systems, which reduces demand from local electricity suppliers.

Is Geothermal a Viable Option for North Texas Homeowners?

Monday 25 May 2015 17:17
Written by

Understanding geothermal heating and cooling is the key to deciding if it is the right option for you in your Dallas home. The first thing you need to know is that it is a renewable energy source. It still runs off electricity, but in a much more efficient way and the source of energy (heat) comes from the earth.

The layers of underground earth are typically between 54 and 67 degrees year round in north Texas. That temperature remains constant throughout the year because the ground actually absorbs nearly 50 percent of the sun’s energy. Geothermal heating and cooling taps into the energy stored underground and puts it to work for you in your home.

The first thing you need to consider is the impact geothermal has on the environment. A geothermal heating system has no emissio06_26_13ns, so there are no greenhouse gases that harm the environment coming out of it. It consists of a heat pump, plastic or copper lines buried under the ground, and of course your heating ducts. As a matter of fact, it is actually a very quiet system that will allow you to sit back and enjoy the natural ambient noise around your Dallas home. You might actually enjoy hearing the wind blow or the leaves fall. Maybe even hearing squirrels chirping and playing in the trees.

The earth’s heat powers a geothermal unit, but that does not mean it is only good for heating. Geothermal is fully capable of cooling your home as well, just as much as your old system does. When it comes to cooling, the system’s flow is simply reversed to achieve the cooling effect. We will talk more about that in a moment.

The information that is probably at the top of your mind right now is the energy savings, or how much money will it save you and how long will it last? Well, let’s just give you a little perspective on it first. For every dollar that you spend powering geothermal, the unit returns $4 dollars’ worth of heat. Old HVAC systems are usually about 94 percent efficient, but a geothermal system is 400 percent efficient. So you can expect to see a minimum of 30 percent savings, but more realistically, closer to 80 percent energy cost savings - and it will last for many generations to come.

Just keep in mind that the cost of installing a geothermal heating and cooling system is higher than traditional HVAC systems, but it will pay for itself in just a few years. Also, you will qualify for a 30 percent federal tax credit, in addition to state incentives. But, don't go trying to save money by installing geothermal yourself. In order for you to get the many years out of it you can expect, it needs to be installed correctly by a skilled professional that has experience in knowing where and how to lay the loop field. Otherwise, the system may not be able to harness the energy it was designed to produce.

Okay, now that we discussed the benefits of a geothermal system, let’s take a look at how it works. As we have already mentioned, the loop field, or heat exchanger, consists of several underground pipes that are either filled with water, antifreeze or a mix of both. These pipes are routed and buried through a system of underground loops, which absorb the heat. Depending on your location, the field can spread out horizontally or vertically. A skilled professional will have to make this call after he has taken everything else into consideration, including the blueprints of what is already down below the surface. The last thing he wants to do is hit a water pipe or a sewage line. Septic tanks can also heavily affect the layout of the loop field. But like we said, a skilled professional will know what to do in these situations.

Although you only need to go about five feet below the ground to reach the warmer geothermal temperatures, most contractors will go between 50 and 100 feet. In the case were there is an aquifer present, they will also make use of that as well, extracting the water then replacing it so nothing is consumed and everything is returned to the environment. But that is for a more complex, modified setup and we will stick to the basics here to help you understand.

Once the pipes are underground and the geothermal heat pump has been installed, as well as the air ducts, you are ready to fire up your system. During the winter when it is cold and you are trying to get the home comfortable, the water and antifreeze solution makes a constant loop through the field of pipes, pulling the cold air in your house with it, and returns back to your heat pump with a heated air temperature that has been absorbed and extracted from the ground. You might say that your home air is constantly traveling on a “comfortable temperature tour.” The heat pump then warms the air some more and circulates it throughout your home. This is where your energy bill kicks in, but the water in the loop field has done most of the heating so your heat pump does not have to work nearly as hard (you might even say 80 percent less).

But, when the summer months come along and it is time to cool the house, the geothermal system works in the same way, just in reverse. Basically, the hot outside temperatures will have heated your air enough so that when the air circulates into the loop field of pipes, the underground temperatures cool it down and loop it right back into your building. In most cases, 67 degrees is more than cool enough for the summer comfort.

To sum it all up, there is absolutely no down side to geothermal heating and cooling. It is better for the environment, better on your energy bill, it runs quietly, the government will give you a tax credit and the renewable energy source under your feet will never go away. With so many benefits and no repercussions, wouldn't it be worth it to find out more?

Is Geothermal The Right Choice for Your Home’s Cooling Needs?

Monday 25 May 2015 17:14
Written by

Geothermal energy is becoming increasingly popular, and for good reason. There are certainly many advantages to making the switch to a geothermal system for cooling your home. The air temperature around our homes may fluctuate with the seasons and the time of day, but the ground on which our homes stand stays remarkably constant throughout the year. It is these stable temperatures underground which can be harnessed to provide cooling, heating and hot water systems which are incredibly energy efficient -- this in itself is always a great selling point for the majority of homeowners these days. As energy prices soar and we are all made increasingly aware of the importance of turning to eco-friendly energy solutions, a geothermal solution is quickly becoming a more common choice for homeowners.

Most people are familiar with the concept behind solar energy, but many do not realize that around half of that energy is actually absorbed into the ground – and utilizing that energy can help to save up to 80 percent on the energy we use to heat and cool our homes and provide hot water for our showers and baths.

So how do geothermal energy systems work?

The usual model for a geothermal system involves sealed piping, which is placed beneath the ground through which water circulates with a little help from a heat pump system. This helps facilitate the exchange of heat between the earth and your property. During the colder winter months, the higher temperature of the ground is absorbed, concentrated and pumped into homes providing a warm,comfortable stream of air. During the summer the opposite can be employed. In this case, the heatpump absorbs the heat from your property before transferring it into the circulating water system,leaving your home feeling cool and comfortable.

Installing a geothermal energy system for your home can help to save a substantial amount of money on energy bills. The systems have considerably less work to do than more traditional heating and cooling systems – whereas furnaces utilizing fossil fuels are generally 80 percent to 90 percent efficient, many of these geothermal heat pumps have incredible efficiency of up to 450 percent. Not only does this help to reduce your heating and cooling bills, but it is also an incredible Eco-friendly method of heating and cooling your home.

We all have to do our bit these days to help preserve fossil fuels and reduce the carbon emissions which are slowly strangling our fragile planet. Geothermal energy systems are just one small step which can help you to do just that.

So is geothermal the right choice for cooling your home? Why not call in the experts and find out?
