Michael Sorrick
I’m sure that a lot of HVAC Companies are similar to Top Flight. I called them and ask the to come out on a weekend because I didn’t have heat. While they were on their way I figured out that I had a bad contactor. When the guy arrived, I showed him the contactor. He didn’t have one in his van. So he had to go get one. He replaced it and checked over the rest of the system and say I was low on refrigerant. He came back two days later and added 1/4 lb of refrigerant. I paid $1,488 for them to replace 1 contactor and a 1/4 lb of refrigerant. I was totally RIPPED OFF. I definitely would not recommend them!
Response from the owner:Thank you for taking the time to share your feedback. We genuinely regret that your experience with us didn’t meet your expectations, and we’d like the opportunity to address your concerns.

We have been a Top Flight client for several years now. Top Flight offers an excellent service plan and exceptional customer service. Their technicians are very knowledgeable, courteous and take their time explaining any issues they may see presently or in the future. No hard core selling. Service calls are always timely.Their automated system provides you with accurate information for your technicians arrival. More often than not, their trucks carry a great inventory of parts, should you need any replacement items during their visit. An honest company with ethical, dedicated employees.
