"Geothermal heat system repair and maintenance"

"Replaced shutoff valves under sink"

"They came on time and install the system, which is working well. Their prices were the best for the of the quotes that I received for the same type of unit."

"It went well under the circumstances. I found out that day, that my water had been turned off without my knowledge by America Water, which made it impossible to hose down and clean the outdoors unit. They did their part so I was satisfied. It would have been outstanding if they were willing to come back out to complete the cleaning when water was turned back on, for a perhaps half the price ($49.99). They would only come back out for $89.99."

"Job well done. More pricey than expected since we had more vents and main lines than expected but overall very good service."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"My air conditioner decided to go out at the end of an excessive heat warning in my area. I looked around on Angie's list and found Gant heat and cooling. I am sure glad I did. When I called him and he asked a couple of question to see if I could do a quick check on somethings and fix it myself. Well I could not. He came out within 45 minutes of me calling and was done in about 15 mins. He communicated the problem and told me what he was going to do. Extremely nice and knowledgeable and a Air Force Veteran. I highly recommend this company for all heating a cooling needs. I will definitely use him again for any future needs. The picture below shows what he replaced"
