Stalwart Air Conditioning & Heating Services

Ato came within the hour and was able to find the issue (Wires inadvertently touching which blew a fuse) with our upstairs unit in less than 7 minutes. Very professional as well....all the way to putting the covers over shoes as not to mess up the carpet!

Walter was professional, courteous and knowledgeable. Not only did he fix the issue we called about, he also fixed past issues not addressed by others. Highly recommend.

I strongly recommend Stalwart Mechanical Services. They are very professional and fair. Walter and Ato do a professional job at a fair price.

Stalwart Mechanical is the best HVAC company in Houston. They are professional and fast. most of all his price was fair.

These guys are great, same day service, reasonable prices, were very professional from the dispatcher that took my order to the gentlemen that came out to repair my a/c, all around the best service I've ever had from an a/c company

Geoff was very courteous and he explained the problem what was wrong with my AC. I highly recommend Stalwart.

Called Them because my heater was not working they came out same day and fixed the problem would highly recommend this company fast honest and great price

Ato cam out to meet me within a hour of calling and did an excellent job of repairing my a/c and at a very reasonable price. I highly recommend!

I happened upon this review board while searching for someone to come out and troubleshoot my home ac system.I was highly impressed with how quickly the problem was diagnosed and resolved. I will be referring Stalwart to everyone I know.

I highly recommend Ato for all your Air Conditioner needs..he is very reliable & extremely knowledgeable, a well as the best prices around Houston.
