Frontenac HVAC — Repair, Replace, Done.

Very prompt response and very professional and conscientious repair service. Nick did a great job and is a very nice guy. I apparently have an intermittent problem that did not occur today. Your technician was excellent and system is now working, so I will call if issue recurs. You have terrific associatyes.

I can’t say enough wonderful things about Thomas Hoffmann Air Conditioning and Heating! Nick came promptly, which was such a relief, and from the very beginning, he was personable, professional, and incredibly honest. After dealing with other companies, Nick’s honesty really stood out. He took the time to explain everything clearly, answer my questions, and make sure I understood what was going on—without any pressure or unnecessary recommendations. It was refreshing to feel like I was dealing with someone who genuinely cared about doing the right thing for the customer. Nick’s professionalism, knowledge, and customer service were truly top-notch. I wouldn’t hesitate to recommend Thomas Hoffmann Air Conditioning and Heating to anyone looking for a heating and cooling company you can actually trust!

They did great work on a tight timeline. They saved our business that day! Very professional and smart. I will use them every time!

The service was excellent! When we arrived home after 8 pm, seen our unit was not working and it was almost 85 degrees in our home my husband began calling all of the companies that said they were 24 hrs. Thomas Hoffman heating and cooling was the only company that honored the statement. Nick was at our home in a very timely manor and was also able to fix our unit quickly! I would highly recommend to anyone needing any hvac services!

Excellent service and a job very well done. Highly recommended!

Tom was amazing and fast , came out for a 24 hour service call and did quick work to keep us in our home during a summer heatwave.

Excellent service, on time, professional!

Thomas Hoffman HVAC provides excellent service. The staff members are very nice, respectful and knowledgeable. I always feel comfortable with the advice I have been and the fees for repairs. Whether we see one of the companies employees or Thomas himself we have always had a good experience and highly recommend them. I am thankful to have found a trustworthy company to count on for my future needs.

Everything went very well , excellent service, our AC should be good now .

Nick did an outstanding job on checking the attic and replacing damaged insulation. He showed me where the leak was coming in from the roof. Excellent overall job

Fast, friendly, professional service.

Nick is very professional and have our AC issue resolved within an hour.

I was distraught to find out our 20 year old HVAC needed to be replaced. Hoffman was beyond empathetic and took care of me within 24 hours during the heat wave. They were on time and very efficient. I have to have trust worthy people work on our house and be in our cocoon, therefore Hoffman has always been our contractor and always will be! They have become family;) I refer all of my clients to them!!!

I called on a Monday morning as air conditioning was blowing warm air. They were able to come to my house very early afternoon and fixed the problem. Would highly recommend and will use them again.

Thomas Hoffmann provided outstanding service from start to finish. The technician was professional, knowledgeable, and took the time to explain everything clearly. They arrived on time(early), diagnosed the issue quickly, and had my AC running perfectly in no time. I really appreciated their honest recommendations and fair pricing—no pressure or unnecessary upselling. It's refreshing to work with a company that truly values customer service. I highly recommend Thomas Hoffmann to anyone looking for reliable, high-quality HVAC service.

Got a checkup on the hottest day of the year and everything is working fine. Great service.

Outstanding...Giovani was superb..need him as a regular for our regular maintenance!

Service Technician was very nice and friendly.

Quick service, solved the problem. Thanks!

The repairman arrived at around 8:30 AM and spent about three hours working on the unit, which I purchased from them less than a year ago. At the end of three hours, he informed me that my unit was not working because I had the wrong filter in it. I raised a question about why it took three hours to replace the filter. I can't really explain his response because it was in technical jargon that I did not understand well enough to know what other questions to ask. The unit has a two year parts and labor warranty and a 10 year manufacturer parts warranty. unfortunately, I did not get the benefits of those warranties because, as the technician put it, the onus for using a less effective filter, rests with the customers. Then, he went on to describe to me the best filter choice, something the average customer would not automatically know. My greatest disappointment was being denied the benefits of my warranties. On the plus side, once management became aware of my dissatisfaction, they reached out to me with an apology for any role they played in my dissatisfaction and, as a show of their good intentions, they shredded my check, subsequently, not charging me for their service. This response showed a genuine commitment to quality and efficient service, as well as a commitment to customer satisfaction. Consequently, I highly recommend Hoffmann Air Conditioning services.

My experience was very pleasant. Nick was great got my problem taken care of. He explained how to use my new equipment . Thank you for a true 24 hr service.

Very prompt, conscientious and personable. Work well done.

The tech was great. He showed up on time, was very polite, answered all my questions and got the job done. The service was also very reasonably priced.

Technician, Giovanni Leone, did such a great job in fixing our AC on a Saturday morning when the Temp is supposed to get up to 100 degrees, later today! I felt like we were in excellent hands and he explained everything he was going to do and then explained in even greater detail once everything was done! I told him if he ever wants to go into sales, he should! He has great personable skills! We have used Thomas Hoffmann before for our heating and cooling needs and they are always professional and trustworthy! My only mistake was not having them to come out to check our AC in the past 3 years!

He came early and identified the problem ordered the part and put it in. He was professional, neat in appearance. I would say an asset to your company.
