The Local Difference
From Parkview to The Loop, U City Is Our Kind of Town.
University City’s housing runs the full range: century-old homes in Parkview and Ames Place, mid-century blocks near Heman Park, and everything in between. That mix means radiators and boilers next door to modern high-efficiency systems, and we work on all of it. This is a business Tom Hoffmann owns outright, not a franchise wearing a local name, so the person accountable for your job lives where you do.
One Owner, One Name
Tom’s name is on the trucks and on the work. No parent company, no rebrand, no pass-the-buck.
Years in St. Louis
Three decades of local systems, local weather, and local houses, including U City’s oldest.
Estimates in Writing
You see the number before we pick up a wrench. Nothing added without your say-so.
Phones Always On
Midnight, Sunday, Thanksgiving: a real St. Louis dispatcher answers, not a machine.
No heat in U City? No cool air? Don’t wait it out.
Heating and cooling failures get worse, not better. Call any hour and a real person picks up, gets the details, and puts a technician on it as fast as we can get one to your door.

Good Questions
What U City Homeowners Ask Us
Do you offer emergency HVAC service in University City?
Yes, around the clock. If your heat or AC fails at any hour, including weekends and holidays, call (314) 471-7625. A dispatcher answers live and gets a technician moving as quickly as the schedule allows.
Do you work on boilers and radiators in U City’s older homes?
Yes. Neighborhoods like Parkview and Ames Place still have plenty of hot-water and steam systems, and we service them alongside modern forced-air equipment. If you’re weighing whether to keep a boiler or convert, we’ll lay out both paths honestly.
Which brands can you repair?
All the major ones: Trane, Carrier, Lennox, Rheem, Goodman, and most others you’ll find in a U City basement. For new installations we’re an authorized Trane dealer, which means factory support behind every system we put in.
What areas around University City do you cover?
All of U City plus the neighbors: Olivette, Clayton, Wellston, Overland, the Delmar Loop area, and the wider St. Louis metro.
My AC runs but the air isn’t cold. What’s going on?
Usually one of four things: refrigerant is low, the filter is clogged, a breaker tripped, or the compressor has failed. A filter or breaker you can check yourself; the rest needs a technician. Call us and we’ll pin it down on the first visit.
How long does it take to replace a furnace or AC?
Usually one day, start to finish. You’ll get the timeline before work begins, we keep the area clean, and the aim is always a running system before we pack up.
