Heating and air conditioning service built around Saint Louis
Serving Saint Louis and the wider St. Louis County area, our crews carry the common failure parts on the truck — capacitors, contactors, igniters, flame sensors, motors and filters — so the first visit is usually the last one.
Homes in St. Louis County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
The busiest week of our year in Saint Louis is the first stretch of sustained may weather. Systems that idled all season fail in clusters.

Saint Louis63122 HVAC questions, answered
What brands do you service in Saint Louis?
All of them. Our 63122 technicians are trained on American Standard, Bryant, Carrier, York and essentially every other residential brand sold in Missouri, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you service commercial and light commercial properties?
Yes. Around Saint Louis we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Saint Louis, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Are your technicians licensed and insured?
Every technician dispatched into Saint Louis is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
