HVAC reviews in Houston, Texas

Forest D. Woods did a really great job at fixing my air conditioning with a prompt and fast service. He has really saved me a lot of money over many years of servicing my A/C and heat. His prices are very reasonable. Thank you very much!

Dean came out on short notice on a Saturday and we appreciated that! He had to order a part but he resolved it on Monday. So glad we found him!

I called during the COIVD-19 pandemic and they came out same day after correctly diagnosing the problem over the phone & giving me a quick quote. When he came, he inspected my unit, unclogged my AC and refused to charge me because we are close and it was according to him a simple fix.

He then told me next steps on how to address a previous "repair."

During a time of crisis this company went above and beyond. He was professional, prompt and most importantly HONEST.

That is unfortunately increasingly rare. We now have an HVAC company for life.

Thank you Celsius AC & Heating!!!

Very prompt response time. Friendly and professional. Fair prices, honest work.

Have used Dean for many years now and always received quick responses and good service for heat and A/C repairs and installations. He is professional and explains all options and recommendations before repairs. Good to have someone to trust.

Dean came out to my house today (sunday). He was very professional and explained everything to me and even gave me tips on how to keep my unit running efficiently! I will use this company again!

Dean and Leslie are angels....Dean came over last night (Sunday) at 9:30pm on Memorial Day weekend and fixed our AC in 20 minutes...God blessed us with Dean and we wanted to say what a wonderful experience. Thanks again to Dean and Leslie for saving us, they are super hero's....Use the guys they are wonderful.....and very reasonable pricing as well.

At the height of rolling black outs and 40+ hours with no electricity, Dean came out and got our furnace back on and running. Struggling at his own home with a leak in the attic from freezing temperatures, dean came to us within 10 minutes to work on our own heater. Thankful is an understatement and in a time of need during this historic 2021 Winter Freeze, Dean was there.

I had a A.C. problem around 9p.m. i called 5 a.c. companies and no one wanted to come out then i called Dean with Celcius A.C and heating. He Came out within 30 minutes of the phone call. He fixed our A.c. the capacitor went out. He was very courteous and efficient. I highly recommend Dean and his company. I will definitely use his services again.

1am on a Sunday morning I woke up and realized my AC was not working. In this Texas heat and having a 1 year old I knew I needed someone out quick. I made multiple calls to large companies claiming to be "24/7". The earliest someone could come out was Wednesday! I called Celsius and a technician was at my house within 15 minutes! Repairs were done quickly and he had the parts needed on hand. I am very grateful for such a quick response and great service.

My air conditioner stopped just before a large family gathering I called Celsius told them of my predicament a nice young man named Dean came came right out and had it up and running in short order saved the day.He did not try to sell me a new unit that I did not need instead replaced a part which he had in his supply truck.THANK you Dean for being a honest repair man. I was also very surprised that my bill was so reasonable since I called him out on a Sunday morning. B.Pringle

Dean, runs a #1 A/C & Heating company!!! Nothing but GREAT. POSITIVE,
SUPER FRIENDLY can describe him and his company. He has always returned our calls promptly and comes out as promptly as he answers his calls whenever we needed him even after hours. He was highly recommended by my daughter who has used him in the past as well. I highly recommend him and will only call his company if ever needed again but his work is highly impressive, and excellent. I trust him so much I will recommend him and only Celsius A/C & Heating, Inc., to anyone who needs has A/C & Heating issues, Dean is your GUY to call.

I found Mr. Dean through googling when my AC unit went out on Monday. When I called him the first time I told him what I thought the issue might be and he listened very patiently and told me what the rates were going to be and said he could come out right then because I have 2 small children. I told him I didn't know and needed to think about it and he said well call me back and I'll come right out. Well I ended up deciding to go with him and he came right on out and fixed it for me. Dean was a blessing and I will happily recommend him to anyone I know that has AC issues. Thank you so much Mr. Dean!

After trying unsuccessfully trying to find an after hours A/C repair person on a steamy August evening, I found Dean. He came out at 11:30 pm to fix what turned out to be a clogged drain and saved us from the current heat wave. He was friendly, professional, and up front about what was going on instead of leaving us guessing. I can't praise him enough for his work, and I would gladly use his services again.

Dean literally just left our house and I just HAD to come on here and rave about how amazing of a man and company this is. We called him at like 8pm, he was here by 8:15 and was completely finished by 8:40. My husband was out there (wanting to learn, had a million questions) and Dean was so patient and knowledgeable! He literally finished up right before the storm rolled in! (It's now pouring!!) Love this company and love Dean! He will forever have our service!

Dean has now replaced 2 central heating and air full units, over the course of 25 years. He has always been fast, courteous, affordable, and on time. He is an absolute professional. He has diagnosed and fixed many of my friends and family's units over the years, as he the only one I would ever recommend. If you want FAIR, QUALITY, and Competent, Dean and Celsius is the only way to go! Thank you Dean for MANY years of great service!

Called Dean at 9:15 pm, was on the phone for a couple minutes, he said he would be right over. Less than 15 minutes later he was in front of my house. His thoughts conveyed on the phone of the problem turned out to be accurate. 15 minutes later my unit was running and cooling down the house.

Dean then proceeded to crawl into my attic to inspect and look for any other issues, which there were none. Very patient, polite and knowledgeable. Took the time to explain things, and overall very professional!

Highly recommend!

Elie & Joseph came back yesterday when I needed clarification with the smell problem in my heater. I had them checked my heaters way back in December. They are very professional technicians and a team.
I like to recommend them to all!

I contacted Kelly's and they attended to me the same day. I am very happy with the service provided by the technician Kenneth, he was very kind and solved the problem with my air conditioning with great technical skills and speed. I recommend Kelly's and especially Mr. Kenneth.

Elie is my guy! He always takes care of me and I can’t wait to get the insulation soon as that’s the last step to optimizing my home. Jospeh was very knowledgeable and Raz in the past was also exceptional! Highly recommended!

My Kelly’s AC serviced our air vents on 2/20/2025 and they did amazing! They were on time, professional, did an amazing job and it was not an inconvenience as they quickly took care of the air vents in the entire house in just 2hrs. Thank you!
