Geothermal heating and cooling is the latest trend in climate control. Thanks to its passive nature, geothermal is ultra-efficient yet still effective. Here’s what you need to know if you’re thinking about retrofitting your home in Annapolis, Maryland, with a geothermal system:

Fuel Matters

Service technicians typically install geothermal systems in new construction. This is easier than retrofitting because the service technician can tailor the home climate control system to geothermal, including the installation of the pump and the design of the ductwork.

However, that doesn’t mean that older homes can’t benefit from geothermal. If your current climate control system uses natural gas, propane or heating oil, your home may be the perfect candidate for a geothermal system. The new system will easily fit in the mechanical space left behind by the old HVAC unit. It can even use the same ductwork.

Electrical systems are a little bit more difficult. If your house uses electricity for heating and cooling, you should consult with an expert before making a decision about geothermal.

The Retrofitting Process

Geothermal systems use a series of pipes below the ground. During the winter, they work by transferring heat from the earth to your home. During warmer weather, they remove hot air from your home, lowering the temperature inside it.

The pipe system that allows your home to use this passive energy process requires significant construction. You might disturb any landscaping. Therefore, homeowners should be prepared to deal with the disruption of excavation.

Upfront Cost

One of the most important considerations is budget. Geothermal systems, whether retrofit or for brand-new construction, aren’t inexpensive. The higher upfront cost can be an issue for some homeowners.

However, the perks of a hyperefficient, environmentally friendly geothermal system can’t be overstated. You also might be able to take advantage of federal and state tax credits that are often available for geothermal installations.
