How quickly can you respond to a heating emergency?

We answer emergency calls 24/7, including weekends and holidays. Call (314) 471-7625 and you'll reach us directly — not an answering service.

Why is my furnace blowing cold air?

The most common causes are a failed igniter, a dirty flame sensor, a tripped limit switch, or a gas supply issue.

Do you service all furnace brands?

Yes. We repair and maintain all major brands — Trane, Carrier, Lennox, American Standard, Rheem, Goodman, York, Amana, and more.

How long does a furnace installation take?

Most residential furnace installations are completed in a single day.

Should I repair or replace my furnace?

If your furnace is over 15 years old and the repair costs more than $800–1,000, replacement usually makes more financial sense.

What areas do you serve?

We serve the greater St. Louis metro area including Chesterfield, Ballwin, Kirkwood, Webster Groves, Creve Coeur, Manchester, Maryland Heights, Des Peres, and surrounding communities.

What's included in a furnace tune-up?

Our standard furnace tune-up includes a heat exchanger inspection, burner cleaning, igniter and flame sensor check, flue and venting inspection, filter check, thermostat calibration, electrical connection tightening, and a full system performance test.

Is a heat pump better than a furnace for St. Louis winters?

It depends. Heat pumps are highly efficient in moderate cold but can struggle in extended sub-freezing temperatures without a backup system. For St. Louis winters, a dual-fuel system often gives you the best of both.
