    The employees showed up on time were done in 7 hours and didn't leave a mess A .

    Extremely rude and condescending when he found out it was just a mini split start up. Instead of a simple no we don't do that he kept me on the phone to lecture me and acted as if he were angry with me for trying to save money by installing it myself and then having it charged by them. Install costs more than what I paid for the units and I can't afford it. He said do you understand what I'm saying to you right now and went on a condescending rude and offensive rant.

    5.0 Tyisha M. Coatesville, PA

    Donnelly was very professional. I look forward too our on going relationships. The salesman Jason and the installation team were very knowledgeable and courteous.

    5.0 Dena S. West Chester, PA

    We have been customers of Donnelly Heating and Air Conditioning for many years. Tom Donnelly personally helped me debate the ins and outs of replacing our AC and furnace. He was not pushy at all and I trusted his opinion. His employees arrive and time and are trustworthy, most of whom have been with their company for a long time. I trust them to work in the house when no one is home, and have always been completely satisfied.

    1.0 Sam W. Phoenixville, PA

    The tech from Donnelly talked to his manager and then tried to charge me for a part that did not need repair. I asked him to leave and then called Horizon who fixed my problem without trying to charge me for parts that were not an issue. You cannot trust Donnelly - especially if you are not literate in HVAC. I would never call them in the future.

    On time and courteous

    5.0 Robert K. Exton, PA

    I waited to write this review until all the work as completed and we received the stated rebates. I highly recommend Donnelly HVAC!, The owner personally came out and gave us the best system for our money. All work was completed professionally and on time. I personally do not believe that we would have received a better system or installation even at twice the price. Sincerely, Robert K

    4.5 Denny and linda F. Broomall, PA

    honest and straightforward approach to installing and pricing new gas heater and central air conditioning system. Installers were knowledgeable and paid attention to detail.

    5.0 Raymond P. West Chester, PA

    Great local company here in West Chester, PA. Easy to do business with. Installers were courteous and professional. Lost my heat during the really cold week after Christmas. Great turnaround time and installed a new gas furnace/ac unit with it 15° to 20° outside. No problems 1 month later. Highly recommend.
