Small City, Full Coverage

A Century of Brentwood Homes, One Standard of Work.

Off Brentwood Boulevard and Manchester Road you’ll find 1920s-40s bungalows, mid-century ranches, condo communities, and brand-new infill builds, often on the same block. Each heats and cools differently, and we service them all with the same approach: diagnose honestly, price in writing, fix it properly. Tom Hoffmann owns the company, not an out-of-state group with a friendly name, so the accountability is personal.

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.

Before You Book

Brentwood HVAC Questions

Do you offer emergency HVAC service in Brentwood?

Yes, every hour of the year. Call (314) 471-7625 and a live dispatcher takes the call, weekends and holidays included, and gets a technician dispatched promptly.

Do you service condos and townhomes?

Yes. Brentwood has a large share of condo and townhome living, and we regularly handle the compact mechanical closets, shared walls, and association requirements that come with those units, in communities like Brentwood Forest and elsewhere.

Can you work on both my old bungalow and my neighbor’s new build?

Yes, and in Brentwood that’s often literally the same street. Older homes tend to need retrofit thinking and careful sizing; new construction needs commissioning and warranty-conscious service. We do both daily.

Which brands do you repair and install?

We repair Trane, Carrier, Lennox, Rheem, Goodman, and the other major brands. For new installations we’re an authorized Trane dealer with factory support behind the work.

What nearby areas do you also serve?

Richmond Heights, Maplewood, Rock Hill, Clayton, Ladue, Webster Groves, and the greater St. Louis metro.

How long does a system replacement take?

Most are finished in one day. You’ll have the schedule before we start, the work area stays protected, and the system is up and running before we leave.

Brentwood Comfort, One Call Away.

Locally owned, 30+ years of St. Louis HVAC experience, honest written pricing, and a dispatcher who answers around the clock.
