Technician Sergio trouble shot my AC problem an brought it back running again in no time. He wasted no time removed and replace broken old parts and even provided recommendations.
Sergio was very professional, friendly and the price is very reasonable. If you have AC problem then call Alamo heating and cooling.

10/9/23: Sergio provided a seasonal furnace maintenance check today so efficiently, professionally, with timely tips for optimal regulation and performance, all at eminently reasonable cost in less than a half hour. Words can't fully express my gratitude.
3/11/23: In repairing my Coleman mobile-home furnace Alamo's team has been extremely trustworthy, reliable, professional, fair, thorough, determined to solve problems, get it right! Friendly, courteous, great follow-up, most reasonable costs. A wonderful trio of gentlemen (Sergio, Jose, Alberto) who helped me survive these cold winter rain storms. Alamo Heating and Cooling Inc. exemplifies a commitment to excellence for which I offer my highest recommendation. (:

Edited post: Jose was our technician's name. He was very punctual, professional and honest. He took the time to find the issue. Once he found it, he had it fixed quickly. We actually had two issues, one most likely stemmed from the original install (different company) when AC was replaced 3.5 years ago. The other issue was a burnt out part. We really appreciated the quick service too as I called on Friday afternoon and we had an appointment the following day at 7:30AM which was perfect. The price for parts, labor and the diagnostic fee was reasonable. Jose also provided feedback on the state of our heating system (blower) so we are aware for the future. We would highly recommend Alamo Heating and Cooling! Thank you!

I'm very happy with the service I received from Alamo Heating and Cooling. Sergio was the technician who took my call, and showed up when he said he would. He came ready to deal with the unique challenge of repairing the 4 dehumidifiers that didn't work. I was a bit surprised how fast he delt with each machine. I now have 4 dehumidifiers that work & fell like he was very professional.

The AC was out and the house was uncomfortably hot during a heatwave in the 100s. I called Alamo amongst a few other HVAC companies to repair as soon as possible. Alamo told me they could come the next day, but then called me back within an hour, and told me they were 12 minutes away. Sergio showed up, diagnosed the problem, and fixed the AC unit within 15 minutes. They accept credit, and were able to send me a receipt digitally. Sergio from Alamo showed great professionalism, and know how. I would definitely recommend them.
