The Southwest Corner Counts

Eureka Grew Up. Your HVAC Options Should Too.

Tom Hoffmann owns the company personally, so nobody at a corporate office gets to decide Eureka is too far.

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!

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!

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!
Response from the owner:Thank you, Bill! We're so glad to hear about your positive experience with Giovanni. It's great to know that you felt well taken care of and appreciated his thorough explanations. We truly value your trust in us for your heating and cooling needs, and we look forward to serving you again in the future!

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.

Locally owned, 30+ years of St. Louis HVAC experience, written pricing, and a dispatcher who answers at any hour, all the way down I-44.
