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.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.
