Geothermal Energy for Heating and Cooling

Geothermal Energy for Heating and Cooling


Why Geothermal?

Geothermal takes advantage of what’s already there underneath your home or business – a free & renewable supply of energy!  Geothermal is the most energy efficient method of heating or cooling a home or building, and boasts the following benefits:

  • Extremely Efficient – The U.S.  Renewable Energy Laboratory determined that geothermal cooling and heating is much more efficient than classic HVAC systems
  • Go Green! The EPA concluded that geothermal energy is the most environmentally friendly cooling and heating method available today
  • Save Money!  Many state governments  and utilities companies offer tax deductions or rebates to lessen the cost of installing a geothermal system

While the amount of money and energy geothermal will save you varies by region and the type of system geothermal is replacing, the Houston climate is incredibly hot, so geothermal can save you a great deal of money per month on your cooling bill.

Geothermal Cooling & Heating Saves Money

As you already own your land, you should utilize the energy source that’s right below you feet! A water furnace geothermal installation moves a startling five units of energy for every single unit of electrical energy consumed, making it the most efficient and cost effective way of cooling or heating your home!  You’ll be able to cut the cooling and heating bill by up to 3/4ths (75%!) and even heat your water for free during the summer!

How Geothermal Works


We all know that summer in Houston is unbearably hot.  But right below the ground, that’s not the case.  Here’s how heating and cooling works via geothermal!

 Geothermal Heating

the sun infuses the Earth’s crust with its heat energy. Forty-seven percent of that energy is stored in the ground as heat. Water Furnace geothermal installations utilize this energy potential using an earth loop system; taking advantage this free heat for your home. This innovative technology uses the sun’s heat that the earth has readily stored to condition your home or office.  In the heating cycle, a Water Furnace geothermal heat pump employs the earth loop system to draw the heat from the ground. Delivery through a classic duct system, the geothermal system draws heat from the loops and distributes it as warm air. Other choices are available to use that same heating energy to provide hot water heating and radiant floor heat.

Geothermal Cooling

The heating process is reversed in the cooling mode – creating cool, conditioned air all through the home. Instead of extracting heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.

Geothermal and the Environment

The  Environmental Protection Agency and the Department of Energy ascertained that geothermal heat pumps are the most eco-friendly friendly and cost efficient way to heat and cool your house. Geothermal installations emit no carbon dioxide, carbon monoxide or other potentially harmful greenhouse gasses.  Geothermal Water Furnace units are truly a natural green way of life

Converting Your Home to Geothermal Energy

Geothermal systems are a great alternative for the replacement of older or inefficient HVAC equipment in the Houston, Texas area. Most units are simple to install and can be installed in spaces that would typically be unsuitable for HVAC equipment.  Because no combustion takes place, there is no need to vent exhaust gasses which means geothermal equipment can be installed virtually anywhere.

The vast majority of homes can instantly enjoy the full benefit one our geothermal systems.  Other options include:

  • Radiant in-floor heating – Gone are the mornings of walking on cold tile!
  • Water heating
  • Financing available upon approval, so call now!

One Call’s Geothermal Cooling & Heating Services Featured In Houston News!

HVAC & Plumbing  Co. Gives Houston Area Economy a Boost with Cutting Edge Green Technology

With a focus on conservation, One Call Houston is paving the way for greater Houston homeowners, offering an ecologically sound way to reduce utility costs up to 75%

Geothermal energy is a highly energy efficient and eco-friendly way of cooling and heating your home or office, but remains a largely untapped market, especially in the southern regions of the US where many people assume (incorrectly) that it’s used only for heating homes.  However, that’s not the case, as One Call is proving to home and business ownersalike in greater Houston!

Geothermal heating works via a heat pump that employs the earth loop system to draw the heat from the ground. Delivering air through a classic duct system similar to central HVAC systems, the geothermal loop draws heat from buried pipes and distributes it as warm air, while at the same time providing hot water, and even heating the floor of your home!  This process is reversed in the cooling mode.  Instead of extracting heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.  The result is cool, conditioned air throughout the entire house, using only a fraction of the energy that a traditional air conditioning system would use.

When I asked how in depth installing a geothermal system was, I expected a complicated and perhaps messy process.  “It isn’t” points out Edgar; “we drill a hole and run pipes into the ground, install a small pump and heat exchanger about the size of a traditional AC unit, and you’re good to go – it’s not much more complicated that fixing a clogged sewer line, and it will work for virtually everyone!”.

Why make the switch?  Geothermal energy uses 75% less energy on average than the more typical Air Conditioning / Heat Pump combination found in most homes, and has the added benefit of including hot water.  “Many people aren’t away of the benefits” says Edgar Connery, owner of One Call Houston “nor do they know about the tax breaks & incentives offered for eco-friendly alternatives such as Geothermal.  Instead, they look at the initial up front cost, not realizing they’ll often pay up to 30% less after these incentives and that’s before the financing we offer”.

Houstonians are taking notice, tempted by the ability to cool their homes for as little as $20/month and often slashing their total energy bill by 75% or more: “financing has really put these incredible systems in reach of the average homeowner by replacing rising utility costs with a cheaper, short term loan payment” notes Edgar “and subsequently demand has been crazy!”.

How crazy?  According to Edgar’s HR manager, the company has nearly doubled in size this year alone.  What does that mean for job seekers in Houston?  “We’ve been hiring non-stop since April” Edgar stated when asked.  “We still haven’t caught up, we can’t hire fast enough to keep up with demand – we’re always looking for honest people!”  Excellent news to say the least, especially in the current economic conditions.

One Call Houston is a local service company providing air conditioning, heating (HVAC) and plumbing services to the greater Houston area since 1990.  “We’re one of the few HVAC and Plumbing companies that makes an effort not only to offer our customers ecologically sound options, but also to use these same options in our establishment”.  (A I write this article One Call is in the process of replacing all of their large fleet trucks with smaller transit vans, slashing their fuel consumption and carbon footprint by 60%).  Edgar’s comment?  “One Call has always treated people right and most of our business is by word of mouth because of that.  I’ve decided that we should treat the planet like we treat our customers, with honesty and respect.”
