The Southwest Corner Counts

Eureka Grew Up. Your HVAC Options Should Too.

A town that’s doubled in reach deserves more than whoever happens to be closest. From the older homes around Central Avenue to new construction off Highway 109 and the neighborhoods near The Legends, we bring the same trained crew, the same written pricing, and the same standards down I-44 that we hold everywhere else. Tom Hoffmann owns the company personally, so nobody at a corporate office gets to decide Eureka is too far.

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 associates.
Response from the owner:Thank you, Rich! We're glad to hear you had a great experience with our repair service. Nick will be pleased to know his efforts made a positive impression. We appreciate your feedback!

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!
Response from the owner:Thank you for the 5-star rating, Lori!

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!
Response from the owner:Thank you, Morgan! We're glad to hear that you had an excellent experience with our service. It's great to know that Nick was able to assist you promptly and effectively. We appreciate your recommendation and look forward to helping you again in the future!

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!!!
Response from the owner:Thank you, Katie! We're so glad to hear that you felt supported during a tough time. Your trust means the world to us, and it's wonderful to know that we’ve become part of your family. We appreciate your referrals and look forward to continuing to serve you and your clients!

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.
Response from the owner:Thank you, James, for your 5-star rating; we truly appreciate your support!

Good to Know

Eureka HVAC Questions

Do you regularly service Eureka, or is it a special trip?

Regularly. Eureka is a standard part of our service area, along with the rest of the I-44 corridor. Same pricing, same response standards, no distance surcharges.

Is 24/7 emergency service available in Eureka?

Yes. Call (314) 471-7625 at any hour and a live dispatcher answers, weekends and holidays included, then gets a technician on the road.

Can you handle both older Eureka homes and new construction?

Yes, and Eureka has plenty of both. Established homes near the old downtown often need retrofit-minded repair and careful sizing, while newer builds need proper commissioning and warranty-conscious service. Same crew, different playbooks.

Which brands do you repair?

Trane, Carrier, Lennox, Rheem, Goodman, and the other major names. New installations come through our authorized Trane dealership with factory support included.

What communities near Eureka do you also serve?

Wildwood, Pacific, Ballwin, Fenton, Valley Park, High Ridge, and the greater St. Louis metro.

How long does a full system replacement take?

Usually a single day. The schedule is set before we arrive, the work area stays clean, and the system runs before we head back up the highway.

Eureka, You Found Your HVAC Company.
