Shon helped us out with a door replacement, and a bit of plumbing work by the hot water heater area. He did a good job and would definitely use him again as one of our regular vendors in the southern area of DFW. Thank you, sir.

They're really nice and professional. They're very service-oriented. Once I had to wait about 45 minutes to get my oil changed so they took $10 off the cost just because I had to wait so long. I like them a lot. They seemed to last really well.

Checked the electric plug, then that all the elements were getting power, working his way methodically through the heating system of the dryer, eliminating as he went. Great top down approach. Found the monitor and replaced. All is now working.

Heating Oil questions, answered by experts

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

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.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

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.
