I can not stress how much that I appreciate HEP for their assistance on 07/27/2025. Here is the quick story my AC went out at 3 am on Sunday Morning. At 8 am on sunday I called HEP for help. I assumed that I wouldn't get support until the first of the week. Hence my surprise when Hep said they would get to me between 1pm and 6pm. Now as I sat in my sauna of a house i counted down the hours. Alas I got a call from HEP at 545 pm saying that my technician was delayed. I figured at this point I am in for a hot night and it wouldn't be until the AM until i got support. To my pleasant surprise Patrick from HEP showed up at my place at around 9pm. We got my AC repaired and sorted and the price was very reasonable. Hep now has a customer for the rest of the time I live in my house. Do not hesitate to call they can and will help you.

We needed a repair to our AC system at the peak of last summer's heat and HEP were the only folks who were able to come out (or even answer the phone, for that matter). They actually managed to get someone to our place that same day and relieve our 95° misery. So I was quick to consider them last week when we had more trouble with our 10-year-old system this spring. Again they were very responsive - and although they weren't able to fix the problem right then (a combination of factors necessitated a more extensive replacement) they promptly quoted the more involved work that was needed. I considered other options for a couple of days without seeing an obvious better choice that was available to do the work, then called to say I was ready to hire HEP for the work. Bob Mathews promptly came to my workplace to finalize all the details of the proposal with me... and then arranged for the work to begin within two days, even though it was an awkward downtown job the would require a crane for roof access. When the actual day of work came I had a last minute panic about the specific equipment choice we'd made and Bob was quick to answer the phone and go over the details again, clarifying my area of uncertainty. The team who came to do the actual installation of our new coils and condenser unit consisted of Tommy Fitzgerald and Joshua McCarty, both excellent guys. They were intent on doing a thorough job and communicating what they were up to as they did it. My wife and I both felt completely comfortable with them. All in all this was a great experience, even though it involved suddenly having to spend a bit of cash we weren't expecting to. Thanks Bob, Joe, Tommy, and Joshua - it's great to have working AC again!

95 degrees and my air goes out! Three hours later George arrives. I took only five minutes and all was working. George must have done the repair a million times because he knew just what it was. The repair was $327 but it beat paying $3,000 for a new compressor! George was friendly and had a big smile. I would highly recommend HEP.!!!!
