I was a loyal customer of Hoffacker's for 30 years and had been very satisfied. Unfortunately, my latest experience with the Hoffacker's team was horrible and I won't use their services going forward. The technicians were great. But the pricing ($450 for 40 minutes of service in my home) seemed very high. When I called to request a clarification for the charge, the service manager was rude, disrespectful and did not follow up when he promised to do so. On my third call back to discuss the issue with him, he rudely told me that the company does not want me as a customer and would take me off their customer list. I have never experienced anything like this in any customer service encounter (on any front). Rude. Disrespectful. Horrible customer service. Especially to a loyal, 30 year customer. I won't be giving them business going forward. And would never recommend them to any of my friends.

Heat pump running but not cooling. Technician John took care of business efficiently while still politely answering all the questions I pestered him with. He updated me on the price I could expect to pay, which, considering it was a Sunday call, I felt was quite reasonable. I will use Hoffacker's going forward and I will request John.

They did a fantastic job and were very personable and had done work on our house years ago. Thousands less than other bids I received and they were able to come out right away. They had everything back on within 3 1/2 hours and adjusted the gas lines at no additional cost and are providing a year of maintenance. Even followed up with a hand written thank you note.

They are excellent. We are saving a bundle on our electric bill since they installed it and their service technicians are excellent and always on time. I rarely see a company that is as good as they are and I would highly recommend them.

I've used this company for years. They've always done a good job for me until recently. I was having issues with my system. One of the problems was a heat exchanger issue. Turns out there was a factory recall on this part in my Bryant furnace that they refused to honor. Because of this, I switched to a different Bryant certified contractor that did honor the factory recall. Don Hoffacker's lost a customer over this. Being in a service industry myself, they also lost all the referrals I would have continued to send them. The part that really irks me is that I had to figure out there was a recall by doing my own research. They didn't even tell me.

Response from Don Hoffacker’s Air Conditioning & Heating
We do honor the recall for the heat exhangers, however they only cover one part of it. Our policy is that we replace both primary and secondary heat exchangers for a safe operation of the furnace. Only doing one part does not ensure proper operation and we don't do repairs half way. We apologize for any misunderstanding and hope you receive proper service for the future.

Went great! The repair technician was able to quickly diagnose the problem and replace the part. I was happy that I didn’t have to replace my ancient air conditioner. But when it does need to be replaced I will call this company.

We hired them to replace a broken HVAC system. The estimator showed up on time and gave us the best price by far. We were able to schedule the work quickly. On the day of installation, four technicians showed up and were able to do the job in a very short amount of time. The foreman was very professional in handling the bill. He even called into his office to see if we could get a discount for writing a check. To top it off they mailed us a satisfaction survey. Great company!

The Hoffacker team that completed the work did a VERY professional job. Their price was lower than the other 2 companies we contacted. They were very mindful of keeping the area of my home as clean as possible as it was a rainy day. They answered all our questions and kept us informed of their progress. They finished sooner than expected. We have been customers of Hoffacker’s for over 30+ years and would highly reccomend them.

The tank began leaking overnight. We called at 8:00 in the morning; Glen, the manager was here at 9:00 as promised and gave us an estimate; the crew arrived at noon as promised and had the old unit removed and the new unit installed in just under an hour. No fuss, no mess, they cleaned up and hauled the old tank away. We went with this vendor because they had replaced our HVAC unit a few years earlier. At that time, Glen gave us a floor moisture detector that has been sitting between the condensate pump for the HVAC unit and the hot water tank. It was when the detector went off that we learned we had a problem. Everything was accomplished with speed and efficiency. I highly recommend this vendor for your HVAC and water tank needs.

Needed a new computer board for our furnace...diagnostics took a little while but a new board seemed the only solution. New board took minutes to install once they determined the issue...but quite pricey.

Quote was fair (not the highest or lowest of the ones I got). The installer was prompt, clean, professional and answered about 1,000 questions from me. They installed the steam humidifier, connected it to higher voltage wire, installed condensate pump, connected to water supply/dran, wired to Ecobee3 instead of the crappy Aprilaire humidistat. He removed my old evaporative humidifier, and left the jobsite perfectly clean and tidy. He tested the functionality after installation, and showed me how to operate the new humidifier. If you are considering humidifiers, I would recommend steam powered vs. evaporative. House is much more comfortable now. Would highly recommend the humidifier and installer.

The techs at Don Hoffacker (Michael, Hunter and Scott) did a superb job in replacing our furnace and air conditioning unit. Another tech came one week before to assess the problem and he recommended that our units need to be replaced. Within a week, they came back with new furnace and air conditioning unit. It was a big job. It took them 5-6 hours to finish the job. They were professional, on-time and very knowledgeable on what they were doing.
