Excellent in every way. We initially called Hiller for an AC problem and got a tech scheduled right away. Then I realized the issue was actually electrical, not the AC unit, so I called Hiller to request an electrician instead. Rescheduling was a piece of cake. The customer service reps, available by phone or text, are polite and effective. They even called back to offer us earlier availability so we could get our AC on faster. The electrician, Mike, arrived on time and fully prepared. He replaced a fried breaker box that was preventing our AC from getting power. The initial fix was absolutely necessary, but it didn’t solve the problem right away. Mike kept hunting to find the problem, and he fixed it. He also reviewed our entire breaker box and explained that our outdated system poses some safety issues that we should address. We’re going to address that project next week. The price for Mike’s service was under $400, which is totally reasonable. My house is cool, and my wife and kids are happy. We’re glad we called the Happy Face Truck.
Upstairs R22 AC unit lost gas , need reliable AC so decided to replace the system, job was done in around 5hrs and system works great… Went with a Honeywell Redlink thermostat as system is 2stage heat / cooling .. Hiller team were polite efficient and got the job done …

Gary and his crew did a wonderful job replacing all the old iron pipes in our house. He explained every question I had. Very courteous and professional. I envisioned a black mess from the pipes, but they left no mess clean as before. Gary stayed afterwards to check on everything and answer my questions before he left. My wife and I are happy with his work. We will be choosing Hiller again.
Andrew and Thomas were great. They were prompt, professional, and fixed a challenging drain issue quickly, not long after we first called Hiller for help. We will definitely be using Hiller in the future!
I am grateful to have hired Hiller. The reason I feel this way is due to the personnel that came out to assess and recommend the project to be done. I found the explanations realistic and the ease of communication and financing a def plus.
