"We changed to Hern Heating and Air Conditioning when we needed a major A/C system repair. We spoke to Morgan who was very helpful and scheduled an appointment the same day. Jordan was very nice and explained what was wrong, what was under warranty, what needed to be ordered and the costs involved. We thought the quote was very reasonable. When the parts arrived, it was repaired by Brandon, Henderson and Torrean. E…"

"Great family Business. They did a very neat job on my new AC. I built a new house so they ran new ducts and installed the whole system. Good communication and employees were very nice. Their work was clean and neat the whole time."

In the end, I called another repair co…"

"This company is amazing. They installed my new unit just over a year ago but had a faulty coil that needed to be replaced. Morgan and Jordan were very communicative, helpful and kind. They were able to order the needed coil quickly. Even though the labor warranty was only a year and this was 1 month after, they stood on the warranty and covered it. I couldn’t have thanked them enough!! 1000% would recommend for all …"

"A month and several follow-ups later, these guys can't even turn a quote around for what should be a pretty straightforward job. The last excuse provided was that the owner was on vacation but would get to it upon his return. That was a couple weeks ago. I can't imagine how bad service would get once they actually have your money in their pockets. Definitely look elsewhere."
