Tyler P. did our A/C Maintenance Service today. He was very pleasant to deal with, pointed out and took care of better insulating the refrigerant lines on inside unit & outside as well. Worked quickly and efficiently. Thanks again Tyler.

Tyler arrived on time and did a thorough examination of the system. He was polite, professional and pleasant. He explained to me everything about the system I highly recommend this service.

Tyler from TopFlight was fantastic. He earned a new service subscription customer.A prior tech from Air Temp solutions left the previously working system disabled and not working. Their follow up tech quoted $1,250 for a new thermostat and thermostatic board. Needless to say I searched for another company.Tyler diagnosed a simple but easily overlooked problem. The system was restored with only a service call.Big call out to Tyler and Top Flight!

Isaiah was my technician who performed a routine AC checkup. He was professional, knowledgeable, and polite. I was impressed with the service so I signed up for the annual plan and have high expectations if I ever run into any issues. Top flight was recommended by a friend who had issues and used several companies that couldn’t fix the problem before finding Topflight that did fix the problem.

Glad we switched Top Flight for our geothermal HVAC maintenance.They have a smooth process to set and confirm appointments. Isaiah (the technician) arrived exactly on time. He is exceptionally well-trained, confident, highly proficient, professional, and easy to communicate with.I feel that our HVAC will be in good hands with theTop Flight competitively-priced maintenance program.

Shout out to Top Flight! I had an emergency call and had to turn my heater off. Technicians arrived the next morning. Service, honesty and technical competency exceeded expectation. Thank you.

First service by Isaiah was outstanding, he took time to explain what he was going to service before & after he was finished. I was promptly contacted next day by Christian to set up follow up Appt. Now I understand why they have 5 stars on the Google reviews.

Tracy Niedrowski

We had Top Flight install a new HVAC system. Isaiah and Tyler were great at the installation. They cleaned up after the job which was nice. The plus is the system is nice and quiet compared to our old system and the balancing they did reduced the temperature extremes in our upstairs vs downstairs.

Very professional and explained everything. I love the fact that they gave me different quotes and I did not feel like they were just trying to get money from me. Our house is only 4 years old and have had nothing but problems with the company that put the system in the house. I FINALLY have peace of mind knowing it was done right. I also really liked the yearly maintenance contract and it was not a crazy amout of money. Thank you for your trained technicians.

The other day, when temperatures were in the teens, I woke up to 54 degrees in my house. I went on line to look up HVAC services and saw that Top Flight had many excellent reviews. So I called them. A couple of hours later, Isaiah and Tyler came to my house. I have to say that it was one of the best experiences, if not the best, that I have ever had with a contractor or service person. They were here all day. Isaiah explained everything to me in detail and encouraged me to ask questions. He was so patient and so nice. Of course, they fixed the problem and gave me some good advice. He was very professional but easy going and well-informed. Also, the prices are very reasonable. I highly recommend this company.

We were going through a total nightmare trying to find a company to fix our HVAC system. We tried 3 different companies that took our money and left us with a system that would stop working within a month after they said it was fixed. Top flight found the problem the 1st time they looked at it. It's now been running for almost a year with no problems. Isiah and this company are the best. We highly recommend them. Thank you Top Flight.

As new customers with Top Flight, we were visited by Ryan for an initial system inspection and a review of the various customer programs that Top Flight offered.While Ryan's extensive experience and knowledge of our HVAC system were clearly evident, his ability to explain and demonstrate issues or items in normal, understandable ways impressed us the most as a new customer.Top Flight's office staff has been equally helpful. Christina, in particular, has been exceptionally helpful with all our new customer setups and arrangements.We highly recommend that Top Flight be included in anyone's short-list of an Honest and Polite Customer-Focused service from a well-established local firm.

Average. (I don't give extra stars to companies who demonstrate basic professionalism in being on time or having reasonable customer service). This company is VERY EXPENSIVE! They offer a discount to customers to "become members," which makes their service (which includes way more service than I want or need) appear cheaper by charging smaller monthly payments which add up to much more over a year than others charge for 2 annual maintenance checks. ($420/year for an 1800 sf house, compared to $180/year for the same sized house in Maryland.) This monthly payment plan makes it very difficult to track what service is already paid for and what is being prepaid. Thus they have pioneered a way to keep their hand in your wallet for months after the service has already been provided. No thanks. I don't buy it. They did allow me to cancel -which is apparently unusual for them- although they did not provide a refund for payments I made already for service that I won't get.

What can I say.....BEST HVAC COMPANY EVER! Since moving to this area I have be unable to find a company to actually listen to me and do proper work. Upon a recommendation from a friend I tried this company out and I was not disappointed. Ryan was extremely professional in diagnosing and fixing my issue. He made the whole process easy and as painless as possible. He gave me many options on new systems and even informed me on state and federal rebates in our area. Isaiah is an excellent technician who loves this work and really did an amazing job. He is also by far the most polite server provider I've ever had in my house period. Taylor rounded out this trio and made this an amazing experience. I'd recommend this company to anyone who doesn't want to be pressured by pushy sales people, "know it all" technicians, and "I know better than you" owners.

Had another company come out said I need a new unit. Called Top Flight for a 2nd opinion.. from the customer service on the phone and Ryan who came out I can say I cried... honest reliable friendly and caring.

Top Flight completed my project yesterday and did a wonderful job. They kept clear lines of communication along the way, and the price I was quoted is what I paid. When it came to the day of installation, Isaiah and his crew were on time, polite, and came ready to work. It was a two day install and they got the job done.

One of the only companies in the county you can trust to do a honest job in the hvac industry. I had three companies out to try and fix my issue and they either failed to diagnose it properly or lied and said it was an expensive repair in order to upsell a brand new unit. Isaiah quickly identified a bare wire shorting out against a copper pipe in the fan unit and fixed it charging me the proper amount for the service . He is a young smart and determined technician, but most of all he is honest.

Ron Marra

This company is great and has great reviews i haven't had any problems with them however 1 very big tip do not deal with these company's that have no reviews because they have so many bad reviews that they won't list any at all i got ripped off twice by these company's that come in an hour and so on, so i stuck with this company and very satisfied.

Susan J. Martin

In a nutshell, this company is fantastic!If you're still reading I'm going to elaborate on just why that is. We opened a new small business here in Lewes, DE and when we went seeking a local company to take care of our system they came highly recommended. Ryan reached out to me directly on Facebook to introduce himself and the team. Vey quickly he set me up with Taylor who got the ball rolling. She listened to what we were looking for and sent Mike out to have a look. He was professional and knowledgable in his diagnosis of our newly installed system. For no charge they told me what needed to be repaired and we set a day to do so. Mike and Josh came back (sooner than the appointment time I might add) and did a thorough job gettin our system up and running. Ryan and I talked again about the work and he gave us a very fair price.I am now a subscribing customer and intend to be so long as we are doing business here. I have nothing but great things to say about the entire experience and strongly recommend this team to any business in the state!

Ryan and team were a pleasure to work with. Techs Isaiah and Taylor showed up for both legs of the install and were timely, courteous, and informative. They left crucial next steps for myself as a customer on system care going forward and insisted I call if I run into any issues. Definitely satisfied with the level of service provided by Top Flight and would recommend to anyone looking for a quality experience!

Spoke with Taylor from top flight to schedule our maintenance and air scrubber install. Both her and Ryan were very professional upon scheduling.

Going out of his way to help ensure all of my concerns were addressed during the visit. I highly recommend Top flight all around for their excellent service.
