HVAC reviews in Kissimmee, Florida

The technicians arrived well on time and explained everything completely. They asked if there were any area of concern. When I mentioned the heating section as temps begins to drop, they verify that it was working properly, then they did the complete checkup. They were very professional and knowledgeable throughout. At the end they explained what was done and thanked us for using Graham service. Great job!

I was having problems with my AC going out when it rain. I had someone come out and they told me my filter was dirty and that was causing the compressor to over heat. I changed the filter and scheduled a tune up for the system.
I had a service time between 12 and 2. They arrived around 1:30 and they where here until 4:30. I was told that I had a bad capacitor in the air handler and I needed a compressor and a capacitor for outside unit. I was told I would be better off getting a newer unit. I told them I would need to check around first for comparison prices. I had another company come out to check out the unit the next day at this point the unit was no longer working. The drain line was clogged and that was what was causing the unit not to work.

We did have some issues with the installation and took a couple of visits to get everything straightened out. Every time I had to call them they were here within 1 hour. I can't say enough about their customer service they are fabulous our air conditioner was down over the weekend and they put us up in a very nice hotel that took dogs. Where else do you get that kind of service. These guys are great. My air conditioner works perfectly and I am pleasantly pleased to do business with them. I'm sure that you will be just as happy if you decide to use this company

I am very impressed with this company. They gave me several reminders and also called me ahead of time to say they were coming. The technicians were friendly, kind, thoughtful, efficient, etc. I felt very comfortable with their knowledge and ability. They explained everything clearly, gave me the price and explained why it was needed. They were not pushy, and made it an overall very pleasant experience. I have had the experience with several other companies and this one far out rates the others as far as service, efficiency, etc., etc.. Thank you so much! You are appreciated! It is so encouraging to see young men working so hard to do an excellent job! Thank you!

Technician was very nice. My membership includes inspections, cleaning and tune-ups. He would not clean out the inside of the condenser saying I had to pay extra for that. While doing his inspection he had turned the temp down to 65 and the fan on. After about 20 minutes I'm wondering the temp isn't going down. I go outside and the condenser isn't running. Inside temp is 78. Also, the installers, 11 months ago, put the place where you pour the vinegar where you cannot access it.

Abe came today to do Service maintenance. Very happy very knowledgeable. Very pleasant. Got the job done and left in no time.

In my opinion the worst company to call I called then for a estimate paid $89.00 they called later on for more services I said no they persisted on call every couple of weeks and leaving voicemails I called them ask them to stop calling they called even more and sent emails texted messages more calls called again asked them to stop calling they said they didn’t handle that it would have to be the driver I spoke to him ask to be taken off the list few weeks later they called again asking if I needed service I said no stop calling again they called this had been giving on since the last hurricane

Set up a normal check up with the company. They had bought the company I usually worked with and who I bought my new AC unit from. The night before my check up by chance my unit stopped working. I turned it off and called them the next morning to let them know that it needed to be changed from a check up to a maintenance. They told me that the technician would be at the house anywhere from 12-4. I then received a text that Dan would be there from 11:45-1:45. At 1:45 I called to see if he was on his way and was reprimanded that they had told me 4. I told them about the text and they were confused. A tech named Michael showed up at 4 and told me that my fan was broken and I should get an AC unit from Walmart because they would not be able to fix it until Monday if they had the part or Tuesday if they had to order the part. On Sunday I received another text saying they would be there on Monday. They were a no show so I called and was told he would be here Tuesday. At 10:30 I called to see when he would arrive and they said they couldn’t get ahold of him. I called back two hours later and they tried to call him again. He finally called me back at 1:30 and told me they sent him on another call and that he hadn’t promised me anything. They also charged me at least $200 more than they should have saying they had to order the piece (which was under warranty) because they had to pay $500 for shipping and handling. DON’T use this company. As Michael left he told me to find another company as they were a budget company and did not give customer service.

5 stars all the way. More than 5 stars. Best AC company I could ever ask for. From the technician to the office staff. Everyone was better than great. 100 percent recommend.

I was very satisfied with the service I received from Graham Heating and Air Conditioning. My technician was Ryan who was on time and kind. He provided me with answers to my questions, and I was comfortable having him do service for me. This is importantly to me- also in knowing this company has been serving the Orlando area for many years. Thanks Graham!

Graham H& A has always provided me with great service and understanding and today was no exception. The technicians and supervisor took the time to answer questions and explain my service in detail. I am very happy with this company and have confidence that they will keep my system in good working condition. Thank you for everything. 😊
****9/3/25 I needed Graham AC today because my Unit stopped working yesterday. The service technician,Junior Reyes did an excellent job diagnosing,clearing up and showing me the cause and resolution to the problem. I really appreciate the fast and efficient service of this company.

I am very disappointed with the tech Abe. He has no business talking to the tenant and telling him what is wrong and needs to be fixed. He told the tenant that the air handler was dirty and needed to be cleaned and even showed the tenant pictures. Now guess what, the tenant now has breathing issues. This is very unprofessional and my property management company will never use your services again.

Ryan arrived on time as scheduled and worked diligently to resolve an issue we have had for some time with our new system that other technicians have been unable to fix. Our system is now running properly and we are very happy with the service and the system.

Had them out to replace the insulation and fix my ductwork. They broke a board on the side of my house, stapled through an electrical cord so now my outlets in my bathroom don’t work. Called them back to fix this and because I noticed that the insulation was still falling out under my house. They came and replaced the board, but didn’t finish the insulation or the ductwork repair. They are refusing to even look at the outlets because they “aren’t electricians” nor are they willing to get someone else to fix this issue. I’ve called them five times to come finish the insulation and ductwork and I’m getting the runaround from their office workers saying: “a manager is looking into it and will get back to me.” It’s been almost 9 months since they didn’t finish the job I hired them for and three weeks since I’ve figured out that they never finished the job in the first place.

Wow, what a great technician. Answered every question with great knowledge. Very profesional, glad my unit was healthy. Possabley look foward to seein this company again if needed.

⭐☆☆☆☆
Avoid this company at all costs.
We were loyal Graham customers for years. But this last experience was completely unacceptable.

They reached out to us to schedule maintenance (we didn’t even request it). During the visit, their new, inexperienced technician caused our A/C to stop working. It broke in the middle of the service and never turned back on.

It was 94°F in our Florida home. We became sick from the heat. Our dog vomited repeatedly. Michael, their manager, gave us a weak portable unit that barely helped. A few days later, he told us the compressor had burned out and said we needed either a refrigerant conversion or a new A/C system. First he offered a new unit for $7,000, then suddenly changed the price to nearly $12,000 after speaking with his boss.

All we wanted was for them to fix what they broke—but they *refused* to take responsibility. They kept saying that the A/C failed because it was “too old,” and insisted that it was “impossible” their technician damaged it. That’s absurd. Our unit was working **perfectly** until the technician arrived. It broke **during** the maintenance. Technician-caused issues are actually *very common* in HVAC work.

Eventually, they agreed to install a compressor—but told us it wouldn’t work unless we paid $7,000 for the refrigerant conversion. They knowingly left us with a broken system and a $7,000 bill for something that was *not* our fault.

Totally dishonest, irresponsible, and disrespectful. We feel scammed. Be warned.

Bobby and Brandon came to fix upstairs ac and service both units. Awesome work.. Very kind, courteous and professional. They also came on time and were very efficient. GREAT SERVICE !!

Technician was very knowledgeable had my heat back up and going in no time. He was also very respectful to my wife.

ASAP HVAC Contractor offered prompt, professional service, efficiently repairing our heating and cooling system with great attention to detail."

Our heating system would make loud banging noises. The technician identified a worn-out motor and replaced it the same day. It’s been running quietly ever since. Responsive and knowledgeable team.
