The Saint Louis63102 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Loud banging on start-up (compressor slugging)
Outdoor condenser humming but the fan not turning
Furnace lights then shuts down after a few seconds
Musty or burnt smell the first time the system runs
Pilot light or hot surface igniter failing repeatedly
Yellow or orange burner flame instead of steady blue
Heating and air conditioning service built around Saint Louis
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
Homes in St. Louis (city) 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.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Saint Louis63102 HVAC questions, answered
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Saint Louis see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
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.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Missouri is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Missouri, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
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.
Do you offer maintenance plans?
We do. A two-visit plan in Missouri covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
