Carbon monoxide safety and furnace inspection for Ballwin, MO homes, Thomas Hoffmann Air Conditioning & Heating

Safety First, Comfort Always

A Comfortable House Should Be a Safe One, Too.

Many Ballwin subdivisions were built in the 70s, 80s, and 90s, which means a lot of furnaces are now well into their second or third decade. Aging equipment isn’t just inefficient; a deteriorating furnace can become a genuine safety concern. Our inspections check the parts you can’t see, including heat exchangers, venting, and combustion, so the system keeping your family warm is also keeping them safe. Tom Hoffmann owns the company, and that standard is his, not a corporate script.

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!

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!

Worth Knowing

Ballwin HVAC Questions, Answered Honestly

Is emergency HVAC service available in Ballwin?

Yes, 24/7 including holidays. Call (314) 471-7625 and a live dispatcher answers, gauges the urgency, and gets a technician assigned as quickly as the schedule allows.

Should I be worried about carbon monoxide from my furnace?

Working CO detectors on every level are the baseline for any home with gas appliances. The furnace-side risk usually comes from a cracked heat exchanger or blocked venting in aging equipment, which is exactly what an annual inspection checks. If a CO alarm ever sounds, get everyone outside first and call for help from there; the furnace inspection comes after everyone is safe.

My furnace is from the 90s. Repair it or replace it?

Depends on the repair. On equipment that age, a small fix can still make sense, but a major component failure usually doesn’t. We’ll show you the repair price next to a replacement quote and let the numbers, and you, decide.

What brands do you service?

Trane, Carrier, Lennox, Rheem, Goodman, and the other major names. New installations are Trane systems through our authorized dealership, backed by factory support.

Which communities around Ballwin do you serve?

Manchester, Ellisville, Wildwood, Chesterfield, Winchester, Twin Oaks, Valley Park, and the rest of the St. Louis metro.

How long am I without AC or heat during a replacement?

Usually just the workday itself. Most changeouts finish in a single day, you’ll know the schedule in advance, and the system is running before we leave.
