  • This company is by far the best company you can ever find. They have been helping us off and on for over a year. There was no pressure - no salesy pitch - and they continued to help us even though they knew our system was old and needed to be upgraded. They would come late in the day if needs be, and worked around our schedule. They responded quickly and answered all our questions anytime we had them. Our HVAC was about 15-20 yrs old and was holding on by a very thin thread. They helped keep it alive and buy us some time until we finally pulled the band-aid off and purchased. Because they have been so helpful and loyal to us and amazingly professional, friendly, adaptive to our schedules, etc - we chose to stay with them and install and purchase the new one. Best decision!
    They sent over two amazingly friendly and professional workers - Billy and Alex. They worked very well together. I was shocked but not ONCE did they get frustrated with one another. I know if i had to do something insane like they did - like drag an entire unit through a tiny attic hole and lift and push up another one, and not break anything, etc - that would be super frustrating for sure. They sure didn't show it. They worked together so well! It was outstanding to witness. Normally i would have expected a few grunts or annoyance in their tone considering everything they had to do, but those two are the best team you could find. I highly recommend those two. They worked diligently together, asked each other if they were okay, if they had it or not and how they could help each other, etc. Teamwork at its finest.
    Every single person over the year has been helpful, friendly, professional, and best off all - reasonably priced. They never once treated me like a number or that my concerns didn't matter. I wish all companies worked like this team. Stop shopping around and give them your business. Outstanding Service. Thank you very much.

    Lisa R.

    As a contractor myself, I’ve worked with Reliable on several projects in the past. Knowing their quality of work, when I needed work on my own home I knew who to call. Arrived on schedule. Diagnosed to problem and fixed it quickly. Travis was friendly and helpful and answered my questions. I would recommend them to anyone.

    James B.

    Andy was extremely polite, helpful, and transparent. Reliable Air was able to accommodate my crazy work schedule to service my a/c unit. I am super grateful.

    Jennifer S.

    When I called to request service they were able to send someone out that same day. When Edgar arrived he was polite and courteous. He explained what he was going to complete the diagnostics first. He then explained what needed to be done and made sure I understood. It was very appreciated that he gave me time to decide on my repair because it was going to cost a bit of money. He finished quickly and explained the invoice. Great job!

    Esther T.

    Joseph was very knowledgeable and quick to respond. He knew exactly what needed to be fixed and he was right on it. I thank you all for the quick, fast and in a hurry respond you did for my family and I. Especially during this freezing weather. Thank you Joseph for being so kind and understanding. I will use you guys again in the near future!
