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.

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.

Keep the Ballwin House Comfortable. We’ll Handle the Rest.

One locally owned company, 30+ years of St. Louis HVAC experience, honest pricing, and a phone that gets answered at any hour.
