AC not working in Pearland TX

7 Signs Your Air Conditioner Needs To Be Repaired

During the hot summer months, you rely greatly on your air conditioner. There is nothing worse than a complete AC breakdown on one of the hottest days of the year. Fortunately, if there is something wrong with your air conditioner, it will tell you. Below are seven signs that will let you know that it is time to call a professional in air conditioning repair.

1. Your Air Conditioner Isn't Cooling Your Home ? 

The most obvious sign that your air conditioner isn't functioning properly is when it doesn't keep your home as cool as you would like. If your home isn't getting cool enough, you should first check the thermostat and make sure it is set to the cooling mode and that the temperature on the thermostat is cooler than the temperature in the room. If everything is set correctly, your air conditioner needs to be serviced. If you turn on your AC and allow it to run, and the home and ducts aren't getting cool, you should call a professional. Several issues could be causing the problem, such as a thermostat issue, an electrical problem, a broken compressor, or a leak in the Freon line. It would take a professional in air conditioning repair to figure out what is wrong with the system and then fix it.  

2. The Airflow Is Poor ?

If the airflow coming from the vents isn't as strong as usual, there could be a clog or leak in the air duct. These issues make it difficult for the cold air to reach the vents. The problem could also be a failed blower motor. Because poor airflow can make it difficult to keep your home cool, it is best to immediately call a professional.

3. Strange Sounds Coming From the AC ?

If you hear strange sounds coming from your air conditioner, you should call an air conditioning professional. Even if the air conditioner is keeping your home cool, you still need to have the issue repaired. The sounds likely mean that there is either a loose part in the unit or something that needs to be cleaned. It is best to call a professional right away before the problem gets worse. This will result in you spending a significant amount of money on repairs.  

4. Strange Smells Coming From Your Air Conditioner ?

If you smell mold or mildew when your AC is running, you should call a professional in Air Conditioner Repair as soon as possible. You could have mold in your ductwork, dirty cooling coils, or a clogged condensate drain. These issues can make the air quality in your home dangerous for your family to breathe.  

If your home is covered under a Landmark warranty, you can have your system tuned up before the cooling season begins. During the tuneup, the tech will check the condensation lines for clogs; they will clean the condenser coils and clean the electrical connections. This service will prevent strange smells, ensuring that the air in the home is safe for breathing. 

5. Leaking Or Frozen AC Unit ?

If there are puddles around the unit or ice on it, you likely have a clog in the condensation line. This line removes condensation when the AC is running, and if it is clogged, the condensation will either freeze onto the coils or leak out onto the ground. The issue could be something more severe such as a Freon leak. Freon is toxic and can be hazardous to your family and your pets.  

If you notice this problem, call your home warranty company immediately so that issue can be repaired before it gets worse.

6. High Energy Bills ?

If you notice that your energy bills are higher than usual, it could mean that your air conditioner isn't running as efficiently as possible. If this is the case, the system will need to work harder to keep your home cool, which can cause your energy bill to increase.  

The inefficiency could be due to a system malfunction or the system reaching the end of its lifespan. Either way, you should call an air conditioning tech or your home warranty company as soon as possible.  

7. The Age Of Your Air Conditioning System ?

The average lifespan of an air conditioner is between 15 to 20 years. If your air conditioner has reached its maximum lifespan, there is a good chance that it is wearing down due to normal wear and tear. If this is the case, it is best to hire a professional to inspect the system. If they find that your system has reached its maximum lifespan, you will need to replace it. The sooner you do, the sooner your home will be cool again.

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.
