"Dynamic Air diagnosed and fixed my heating problem on initial visit. This was after another Heating service could not be sure of the problem and suggested I change the exhaust cap on the roof.. How absurd! From now on l'll call Dynamic Air first."

"He came for our heater tune up. He explained to me how the furnace works and what he was going to do. Once the job finished he told me the repair to be done: to change the red sealer on the exhaust pipe to the proper blue sealer. He gave me the amount expected to pay for it and how long it should take. He is very polite and professional."

"Raul diagnosed and fixed the problem quickly and efficiently. Rather than replacing the AC unit, he was able to replace a part and get the AC running. I suspect other Companies would have pushed the much more costly replacement solution."

"Giovanni responded immediately. Was on time, listened to our concerns, provided a timely and competitive quote, and installed our new furnace even quicker than expected. He and his team were friendly, efficient and professional. Cleaned everything up when they were finished. We couldn't be more pleased! Totally recommend GioTherm!"

"Brad Gentile arrived at the location before I did and had already looked at the ac unit in the backyard. I explained to him I have been troubleshot the furnace for 3 days and have a 2 flash external lockout. Brad said, *Ok, let me take a look and see what is going on.* He asked me to turn on the thermostat and call for heat. I went in and did and walk back to the furnace where Brad had already removed the panel and holding down the pin. Pilot light lit and this is where I told him the furnace will click 3 times and the pilot goes out. He says, *Ok* and we both watch all the burners light up. 3 days troubleshooting had Honeywell on the phone with me for over an hour and this man lays his hands on my furnace once and gets it working with no problem. Unbelievable! He shuts it down and says lets make sure it lights up again. It does! I thank him and say, How much I owe you for coming out? He says nothing it was my pleasure. It happens he says, had the same thing happen yesterday. Something special in that mans hands. Saved me $450 in repairs I was estimating. Thank you again, Brad.... John M."
