HVAC reviews in Houston, Texas

Breathing fresh air again is such a relief! The technician arrived promptly and was thorough, taking about an hour to clean out our A/C vents. I appreciated how they explained each step, ensuring everything was spotless. The difference in air quality is noticeable and much appreciated.

After a brief consultation, the technician arrived promptly and installed our new thermostat in just under an hour. Their expertise was evident as they explained the features thoroughly and ensured everything was working perfectly. The temperature control in our home has never been more precise, and the whole process was seamless. Highly recommend for any HVAC needs!

Our AC issue was fixed quickly by Houston Air Conditioning & Heating. The technician was polite and efficient. No complaints at all.

Terrible customer service psh

Always gets the job done no matter how late.

Great service, communication, efficiency!
Definitely recommend!

Professional and affordable HVAC service.

Great experience with Critical air . They fixed the issue within a few hours of my service call . Cooper was very knowledgeable and efficient . Thank you

Great business, can’t say enough great things about em.

They’re friendly, informative, professional, communicative, honest, straightforward, and most importantly they get the job done at a fair cost.

This is the second time Critical Air and their crew have helped us in a pinch:

We discovered the heater for our first floor went out during the night, and someone came out *on Christmas Eve* to help us.

Martin was very clear about expectations from the beginning, and yet, they were exceeded! Cooper came out this morning, got the heater up and running, was incredibly helpful and informative about the whole process, and the overall cost was fair.

This is the second time we've opted to go with Critical Air - and they repeat the same behaviors, so at this point I felt compelled to mention it. I will say that the technicians that come out are knowledgable and get the work done, but that experience is overshadowed by their poor custom service that is facilitated by Martin. On both occasions we've used them, they would quote us one time frame, and after that time was exceeded we would (understandably and rightfully) inquire about an update on their ETA. The first time we did this with them a month ago, Martin was pretty rude and basically gave us an ultimatum in a condescending way. Today was really no exception - he repeated the same level of service after telling us his technicians would be by sometime after 12PM. It's now 2:10PM and we called and he just now told us it will be around 4PM. I won't be holding my breath come 4PM. He should have reached out to let us know of the revised time a we do not appreciate wasting our day since we planned around them coming around 12PM and being here for a couple of hours based on the time he said it would take them to complete the job. I get that time tables can change, but that should be proactively communicated to the customer. And just like last time, when we expressed slight disbelief on the revised ETA, he gave us an ultimatum as if we should be grateful to breathe the same air he does. We probably won't be a returning customer after this experience. There are plenty of other AC companies around, they were the ones we happened to call first since we used them the last time and were trying to give them the benefit of the doubt. Lesson learned.

After a quick inspection, they fixed my A/C efficiently, and it’s running smoothly again. Highly recommend!

Finally breathing easy after the thorough vent cleaning—remarkable difference in air quality within an hour!

Impressed by the technician’s punctuality and expertise during the visit. He quickly found the issue and resolved it effectively. His professional attitude made the experience smooth. The HVAC system is now performing very well. Excellent service provided.

The technicians and team at Comfort Star are amazing! We just had our old, original A/C unit replaced by them and within a day, I can already tell the difference in air quality and air crispness in our home. They were super knowledgeable, responsive, professional and extremely thorough. Scheduling was a breeze and whole job completed in one morning! Highly, highly recommend!!

I own a business so I know the level of standard I hold my own employees and technicians. I sent a request to Comfort Star on their website outlining the issue and they responded within a few hours and said they could have someone out the same day. I wasn't available same day so I scheduled the following late afternoon. Dispatch called me back and let me know that the tech could be there early afternoon if needed - this worked out perfect and he was right on time. The technician (Bert), was one of the most professional and knowledgeable technicians (at any company I have dealt with). In addition to diagnosing and correcting the issue, he gave me a great introduction to Comfort Star and outlined all of the services offered and their capabilities ... never seemed salesy or like he was trying to push anything, just 100% professional technical company representation. I will be using this company from here on out. Excellent Experience.

We have used Comfort Star for a number of years, and have been impressed with the competence and professionalism of their staff. Shane, their technician has just just performed the annual check on our heating system, and I just want to say again, I'm impressed. He knows his stuff! He explained a number of things to watch for, and suggested some DIY tasks that would improve the operation of our unit. That's beyond a regular service call, and its why we always use this company!

Miguel from Comfort Star was very efficient and knowledgeable while inspecting our current HVAC and offering recommendations. Great service and an affordable cost. We recommend Comfort Star to all our friends and neighbors!

Miguel was a top notch service representative. He explained each step in the process and made cost and energy savings tips. He us a credit to this provider.

Friendly and respectful service! Was able to diagnose the issue and address the problem! Highly recommended.

Excellent Excellent service!
Comfort Star will always be our go to for HVAC needs. They have continued to impress us over the course of the years.
Habib and his crew are not only professional, knowledgeable, and competent but most importantly they go the extra mile to make sure their clients are taken care of. 100% Recommend.

We used Comfort Star to replace the A/C unit in our house. We couldn’t be happier with the service and the price. The work was done in a timely manner and efficient manner. We are very happy with our new unit.
