      I had a fantastic experience with Reliable Heating & Cooling Inc. for a condenser replacement in my home! Their team responded right on time, and every person I interacted with was kind, helpful, and professional. They took the time to answer all of my questions and clarified every doubt with incredible patience—their overall service is truly top-notch. A special shoutout to Martin, who made sure all of our issues were addressed on time and was always happy to top off the gas whenever needed. I highly recommend them to anyone needing quality HVAC work!

      I have used Reliable's service for heating and cooling for 20 years. They live up to their name, "reliable". I highly recommend them.

      Before I heard about Reliable heating and cooling, I called a different company to come out and do an air-conditioning maintenance and check up. Next thing I know, the company is trying to sell me a $23,000 system and downgrade me to an 80% efficiency system instead of the 90% that I already had installed. I called Reliable Heating And Cooling to get a second opinion. They told me that the system looked fine for its age and the only thing they recommended replacing was the contactor and capacitor. They said it would be under $300 for the repairs and the maintenance. I would highly recommend this company. They are trustworthy and reliable.

      I have used Reliable Heating & Cooling for over 25 years in two different homes. They are responsive, prompt, skilled, reasonably priced, and friendly. At my former home, they helped me maintain an HVAC system that was over 25 years old and once that one exhaled its last breath, they helped source and install the right unit to replace it. No HVAC system is cheap but this one was fairly priced and is probably still going strong. I invest annually in one of their maintenance plans and it pays off with two seasonal system checks a year. They know my system and its quirks and they can identify issues before they become headaches. I'm writing this review because my AC went out in the middle of the night right before leaving town (and leaving pets at home) during the first truly hot summer week in STL. They came out the same day and had the issue fixed within 30 minutes. I trust Derrick and Marty implicitly thanks to their knowledge and skill. Also, their office staff is friendly and communicative. Thanks, Reliable!

      Amazing and quick response! Was here early in the morning within two hours of calling and had it repaired before lunchtime.
