"Amazing! The problem with my AC unit was a bit of a mystery. I had a service tech named in Fred who checked all the components before checking the brand new thermostat I had installed just six months prior. I don't think anyone would have even thought to check that since the furnace had been working fine in the winter. It had been installed wrong for A C though. He rewired it and my entire unit works fine. I'm certain the last two techs I had here last winter would have sold me a new unit which I really couldn't afford. Polite, informative, expert in this field, Fred and Air Control H&C are simply the best."

Heating Oil questions, answered by experts

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.
