Geothermal Heating And Cooling: Four Myths Debunked

Construction & Contractors Blog

If you find yourself on the fence about installing a geothermal HVAC system in your home, it's most likely due to myths you've heard. Read on to learn the  truth behind geothermal HVAC systems.

Myth #1: I Don't Have Enough Room In My Yard for a Geothermal System

Don't make the assumption that a geothermal system cannot fit into your yard. The size of the unit installed in your yard will depend on many things, including the size of your house and the amount of heating and cooling power it will need.

There are two kinds of geothermal HVAC units: vertical and horizontal. Vertical units, while a bit pricier, are the perfect solution for those homes with smaller yard space. To determine which unit would be a good fit for your yard, you'll have to contact a geothermal installation professional early in the process. With their help, you can determine how much space you'll need and whether you can move forward.

Myth #2: My Home Is Too Old for a Geothermal System to Be Installed

No matter the age of your home, you too can reap the benefits of using geothermal heating and cooling.

When determining how much heat and cooling power your home will need, geothermal installation professionals will perform a heat load calculation. This calculation takes into account the amount of heat lost during the cooler months, and the amount of heat gained during the warmer months. This is especially useful for older homes, as many are poorly insulated and drafty. With the proper calculations, you can be well on your way to a geothermal system that heats and cools your old, leaky home exactly as you need.

Myth #3: Geothermal Systems are Only Good for Heating

Geothermal systems work in two ways: 1) they heat your home by drawing heat from the earth's surface, and 2) they cool your home by drawing the heat from your home and storing it underground.

The first way is how homes are heated in the cooler months. The water in your geothermal system's pipes is heated by the most natural heat source of all—the earth. These pipes then deliver the heated water to the heat pumps that will fill your home with warm air. To cool your home, the process is done in reverse, where the heat being drawn from your home is turned into cool water by the earth, and then returned so as to cool your home to a comfortable level.

Myth #4: It Is Too Expensive to Install and Maintain

While the initial costs of installation can be daunting, the return on investment you get will be well worth it.

Not only can you cut your heating, cooling, and water costs by up to 80%, but you can also receive some sizable tax refunds and rebates for the installation and use of your new geothermal system.

It's also important to keep in mind that homeowners with a geothermal system can save up to $500 in maintenance costs, as geothermal system maintenance is simple compared to that of conventional heating and cooling systems.

With the proper knowledge of how geothermal heating and cooling systems work, how much they cost, and what they can save you, you're now well on your way to making the right decision for your home. Contact professionals, such as those from Cook & Son Plumbing & Heating Inc, for further assistance.
