Our Customer Reviews

"I was very pleased with calling on a Monday on the beginning of a hot week in the last week of July and Hoff was able to come out this afternoon to fix my AC that was not working. I thought the cooling fan on the outdoor unit was bad, but the tech troubleshot it and found the capacitor was bad. He replaced it and checked out the fan and said it was operating per specs. Did not up sale me and fixed what was broken. The price was reasonable too. I’m a repeat customer and this is why I returned. I’ve been fortunate that my unit has worked well for the past 20 years."

"Not only have they completely installed my heating/AC unit but came back to repair it in June 2023. Arrived on time, professional, found a problem on the unit outside, and repaired it, all quicker than I expected but above all WAY below what I expected. They are now my go-to for heating and cooling issues. Keep up the good work!"

"Hoff is awesome! Our AC kept throwing the breaker and would shut off on the hottest days. Hoff discovered the issue, had the part on the truck and fixed it in no time flat! Great service, and great value."

It is a business philosophy they now share with their 2nd generation, ensuring it will be ingrained in Hoff Heating and AC for years to come.
