Get matched with top air conditioning pros in Unionville, PA

"I have been using East Coast Comfort for heating and air-conditioning for years and I have always been pleased. They installed a new system for us years ago, did it for far less than other estimates we received, and we have reduced our energy costs because of it."

"I have been using UIC's services for several years now. They have replaced two older furnaces a couple of years ago with new 2-stage Carrier Infinity units. They have performed flawlessly. Last week our third unit, the main furnace, was replaced with the new Carrier Infinity Modulating Air technology as recommended by Paul, our sale representative. Bruce, Jeff & Wes did a fabulous job on removing the old, and installing the new furnace. They were on time, well equipped, professional, thorough and completed the replacement furnace installation by 5:00 PM. A big job indeed. The new furnace is simply amazing. You must stand next to it to hear it running. The house is much more comfortable given the very slow furnace run modes with continual air movement (undetectable). Another great experience with UIC. I *highly* recommend the UIC team and equally as important, the new Carrier products. Thank you UIC!"

"We recently moved into a house built in 1987 with the original air conditioning unit, which constantly ran without stopping.  It was a brutal summer, but it was definitely not running properly.  Joe came out himself to take a look.  He took a look at the entire system and suggested that we service the AC to make it function properly and not constantly run.  He also changed the air filter in the furnace.  I appreciated the fact that he did not push a new air conditioning system in the house considering the unit we have is 25+ years old.  He also gave us a few ideas on how to make our home more energy efficient.  He did a great job.

"George was awesome - our air conditioner stopped working at noon and he was here by 2pm and got us back up and running by 3pm. Showed me it was just the capacitor and also alerted me to a potential other issue down the road and gave me a quote on it just in case. Pricing was reasonable and I'm gonna use him for service on my unit and furnace as well here on out. I couldn't be happier or recommend him more."

"it wentsmoth to install central air verry happy with it"

"They said there was a bend in the pipe. They said that the quality of the pipe was not very good. Also it hadn't been backfilled properly so it created this bend in the pipe and the air pocket caused a problem. I was out of warranty for the house, it was a year or two after maybe even three years after the warranty. I called them and explained the situation. They said I was outside of the warranty and we are not going to do it. So I kind of threatened them a little bit to see if I could get them to move. They came out and they brought another company who said it had nothing to do with that and it was a blockage between the toilet and the outside. I never saw that. They snaked it and I paid the additional fee for that, and I still have the problem. I didn't continue down the builder path because I thought it was a losing battle at this point. I didn't get anywhere. It's going to run me a couple thousand dollars. You can't get a backhoe in there so they have to dig it by hand and remove the section of the pipe to put a new piece of pipe in there. I had a bathroom in the basement put in. There is a pump that pushes water or sewage out. Whenever I notice there is a problem I force the pump to run and it takes care of the problem because it forces water through the area. Once a month I go and run it a couple times and I don't have a problem. Mattioni was probably right in his assessment. They were very professional. I would use them again. The price is consistent with what other people are charging, but they are pretty high in general. Mattioni recorded it as well. That is something the other company didn't do. That may explain why the were a little higher. They came out when they said the would and did exactly what they said they would do. I said I have a problem and they looked at it."
