We have used Cy-Fair Heating & Air Conditioning since we moved into our home in 2018. They are professional, on time and do great work. We will continue to use this company.

I would highly recommend Cy-Fair Heating & Air Conditioning. They went above and beyond to fix my AC. Lionel was profession, polite and very knowledgeable. He had me up and running again in less than an hour and the price was very reasonable. When it comes time to replace my unit I will definitely call Cy-Fair.

I have been with this company since 1979. I am proud to personally know this family. Back when their was only 2 A/C companies out here ,his company has grown a lot but he still has the same attitude, he treats everyone like family and he will not leave the job until it finished . He has instilled this ethic in his sons and workers. I am beyond proud of the way his company has grown! I would not use anyone else. So don't fret over similar names, if you think you called the wrong # , ask for Harvey or Colt ! His brand can't be duplicated, thank you for all the cool summer days and warm winter nights! Above all thank you for being a friend.

Responded quickly to a call on a holiday, provided options to come out that day or wait until the next. Arrived promptly and was able to fix the problem that day. Very nice service

Cy-Fair Heating & AC absolutely provided the most wonderful experience we could have asked for! Our AC was out and we were lucky enough to have them to fix it in less than an hour of when we called with our issue! The technician was prompt and kind and took care of us so well! We are so grateful and will definitely be using them for all future needs!

After struggling with terrible service from several larger HVAC companies here in Houston, I am very happy to have found Cy-Fair Heating and Air Conditioning. Service was friendly and the units have been running like new since the work was performed. I would highly recommend this company.

I've used cy-fair A/C for a number of years. Always great service and reasonable prices.


My air conditioner went out this week and a friend told me to call this wonderful company. They came immediately and had the new unit in the same day! They are all everything you'd ever want for ac service! Love 'em!

I highly recommend Cy-Fair Heating and Air Conditioning. I would give them 10 Stars if I could. Harvey, Colt and Lonnie are the best! Don't be fooled by other AC companies w similar names. These guys are the real deal. We have a total of 14 AC units at our business and residence and Harvey and his guys are the only ones we let service, maintain and replace them. We have used them for almost 20 years and never had an issue. Truly incredible!

Colt is the best. Trust this company with all my A/C services.

My family has been using Cy-Fair Heating & Air Conditioning for over 20 years. My A/C broke in the early hours of the morning so I called and they got me scheduled right away. I even asked if I could fix it myself and Colt took the time to explain what I needed to do to fix it. I went ahead and kept the appointment and Colt checked things I would have never have thought about and last night i was able to sleep In a nice cold house. Everyone i talk to when looking for a part all suggest to buy a new unit, Colt never mentioned a new unit one time instead he fixed my minor problem and I'm good to go. Thank you Cy-Fair and Colt for your honesty and integrity.


I've had the pleasure of dealing with Cy-Fair Heating & AC since 1998. I think they were the 3rd estimate I got to replace my compressor at the time, and it was by far the best price. Since then they have replaced my other compressor and have kept the heaters and AC systems working beautifully. Once I came home from a trip in July to find out my AC was out. Harvey came out that evening and put a new capacitor in and had the AC going in short order.

We've used Cy-Fair Heating & Air Conditioning since 2018. Harvey, Colt, and everyone else there has been extremely responsive and professional, and they have done great work at fair prices. This morning Colt went above and beyond to work us into the schedule to deal with an a/c that wasn't coming on because of (what turned out to be) a minor issue that he was able to fix on the spot. We highly recommend them for any HVAC work.


Have used Cy-fair Heating and Air for years , It rare in this day and age to have someone you can trust and treats you like Family.
Can't thank yall enough for always taking care of us. John and Terry
