Geothermal HVAC Experts in San Antonio, TX

As extreme temperature swings seem to get more intense every year, many Texas business owners are considering more efficient ways to heat and cool their properties. One of the options is a geothermal heat pump.

Once you get a few feet down into the ground, the ground temperature remains a steady 45°F to 75°F, depending on latitude. Geothermal heat pumps leverage that constant temperature and work by exchanging heat with the ground.

Comfort-Air Engineering & Primo Plumbing, Inc.’s expertise in HVAC means we can offer top-tier services for geothermal heat pumps.

Call us today at (210) 494-1692 to schedule an appointment for your San Antonio business.
