True or False? These Geothermal Myths Are Not to be BelievedGeothermal heating and cooling systems are gaining in popularity in the United States. They provide energy-efficient heating in the summer, by transferred heat energy from a few feet underground into the home, and cool your home in the summer by depositing heat energy from the home back into the ground. They manage this heat-exchange process by transferring the heat via a system of pipes, usually excavated and installed underground.

The Geothermal Heat Pump: Weighing Your Initial Investment Against Long-Term SavingsIf you'd like one of the most efficient ways of heating and cooling your Indiana home, you can't do any better than a geothermal heat pump. These tap into the stable underground temperatures to deliver heated and cooled air. Temperatures above ground fluctuate a great deal, but below the surface of the soil, the temperatures are relatively stable. A heat pump doesn't use any fuel except for electricity and just exchanges or captures heat.

"Our AC went out and they sent someone out within a few hours and the problem was fixed quickly. With our service membership we also got a discount so the repair price was reasonable. I was very impressed with how quickly and professionally they fixed the problem especially in the middle of summer when they must get a lot of AC calls. Will definitely continue to use Hartman Bros."

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"

"Excellent tech, found problem and repaired. Boiler had cracked wire cover, wrapped so it wouldn't arc and proceeded to order replacement. Also checked AC and showed husband where to shut off on outside so unit wouldn't kick on at same time everyday for just a minute or two,, even though AC was off for winter. Great Tech, Great Service! Also checked and placed order for ceiling heating unit for husband 's wood-working shop."
