Trusted Air Conditioning Service in Pearland | Stay Cool & Save

Keep your home cool and energy-efficient with professional air conditioning maintenance in Pearland. Our expert HVAC technicians provide seasonal tune-ups that help your system operate close to its original factory condition, depending on the unit’s age and overall health.

Regular service improves performance, lowers energy usage, and can significantly extend the lifespan of your AC system. During a routine checkup, our team often finds small issues—such as minor refrigerant leaks or worn components—that can be fixed affordably before they turn into major, expensive repairs.

Take refrigerant leaks, for example. When detected early, repairs are quick and inexpensive. But left unnoticed, the system can lose refrigerant, overheat the compressor, and eventually lead to system failure—costing you over $1,000 in repairs, plus higher utility bills from inefficient operation.

Whether you need a seasonal tune-up or a diagnostic check, our skilled team is ready to help. We proudly serve Pearland and surrounding areas with reliable, affordable HVAC solutions. Schedule your AC service today and enjoy comfort and savings all year long.

I want to give a big shoutout to Mike and Walter for their amazing service! They did a fantastic job explaining the issue with our AC unit and how to fix it—without trying to overcharge us with outrageous repair fees. Honest, professional, and reliable. Stalwart Air Conditioning & Heating Services will definitely be our go-to for any future repairs!

Raymond was awesome! He was knowledgeable, thorough, and patient. A real gem! I’m so thrilled to have found a home for my a/c and heating maintenance. Thank you Stalwart for such a wonderful experience.

Such a great company and fantastic service. My a/c stopped blowing cold air at 4 pm. I called for service and they were at my house before 8 pm and the problem was diagnosed and fixed by 830. Our family slept nice a cool all night. You will pay a bit more for after hours service, but worth it in my book. Will use again.

I've been a customer of Stalwart for just under two years now and my experiences with them are at a point that I can safely say that as long as I remain within their service area, they can count on my patronage.

Since moving to this house more than 4 years ago, I've been plagued with non-stop issues with my air conditioning. I originally just utilized whatever company my home warranty would contract to fix my problems or to come out for maintenance. However, whenever the A/C would die in the middle of summer, those same companies would not send anyone out, claiming they were booked for more than a week and that I would have to wait without A/C in Houston summer until then. Those companies also would look at my system, call it fixed, and leave without an explanation or a guarantee. During this time, there was one period it broke down every week after hours on Fridays as if on schedule.

In desperation and frustration after the poor experiences I've had with previous companies, I managed to find Stalwart A/C and Heating. They were the only ones that picked up *and* were willing to send someone (Michael) during that busy time. He promptly diagnosed, explained in a level I could understand, and fixed the issue. He also gave me a price I could not refuse (for the cost of a home warranty contract request for one visit, Stalwart waived the fee for that particular fix and would cover not one, but two maintenance visits for the year). Occasionally during seasonal maintenance, I'd get Geoff, who also had the same expertise and bedside manner as Michael, which helped further convince me that I'd settled with the right company for my HVAC needs.

Most recently, a Trane that we installed broke under warranty, but it was a Saturday at 5 pm and the parts necessary to fix it weren't available until Monday. Raymond, who took my case after hours, was able to troubleshoot and assess the situation professionally and explain the situation to me. If there was anything that I asked regarding what was covered, what isn't covered, etc. that he did not know, he made sure to get the answer from someone who knew promptly. Additionally, he went above and beyond of his own volition to ensure that I, a customer that he met for the first time, would get some level of comfort until the unit could be fixed. Walter, who was assigned to finish the fixes on Monday, drove all across the Houston area to obtain the one part necessary for the final repairs. Isabel made sure to call and text to keep me updated on any delays or developments on the scheduled appointment.

Any time someone entered my home, they came prepared with shoe coverings and they made sure to clean up any mess or debris that may have come from their work. Any time I had questions about something I read that I was curious about installing, they were able to answer my questions and also give me a plain assessment instead of giving me false promises for a quick buck.

In all instances with each point of contact I've had with Stalwart, I have been met with professionalism, transparency, friendliness, care, accountability, and a depth of knowledge that show me that they aren't like those HVAC companies bought by private equity firms who just want a return on their monetary investment. The folks at Stalwart care about doing their job right.

I wish I could do more then 5 stars. Stalwart was great and I could not be any happier with the service. I thought it was just going to be a repair but it ended up that I needed a whole new system. They are professional, accountable, and overall just a great group of people who are not trying to take advantage of customers when there AC goes out in 90 degree weather. If you are looking at reviews of different AC companies in the Pearland then there is no need to look any more because you found the company that you can trust.

On 5/7/25 6pm, I experienced an urgent issue with my A/C unit not blowing cold air. Technician Raymond responded promptly and efficiently diagnosed the problem as an incorrectly installed part from a prior contractor. He was professional, knowledgeable, and addressed all my questions and concerns thoroughly. I highly recommend Raymond and this service for their fast, reliable, and honest A/C repair.

Alto was on time and diagnosed the issue with my AC within minutes and my AC was up and running in less than an hour. I highly recommend this company and will be a repeat customer to serving my AC throughout the years.

within an hour of calling for an appointment, Michael Walters was at my home. Took videos and explained everything before doing the work. Couldn't ask for a more professional, honest, friendly tech. Highly recommend this company.
