How Our Repair Service Works
Schedule a Service Call
Call us or fill out the form. We'll schedule a time that works for you — including same-day for emergencies.
Diagnosis — $125 Service Call Fee
A licensed technician comes out, inspects your system, and tells you exactly what's wrong and what it will cost to fix it. No surprises.
Repair with Your Approval
We don't touch anything without your sign-off. Once you approve the repair, we complete the work — most repairs done in one visit.
System Verified and Running
We test the system before we leave and walk you through what was done. If a replacement makes more sense than a repair, we'll tell you that too.
Common HVAC Problems We Fix
Most HVAC issues we see in St. Louis homes and businesses fall into a few categories. Here's what we handle daily.
System Not Heating or Cooling
If your system is running but not changing the temperature, the problem could be the refrigerant, heat exchanger, or thermostat. We diagnose the root cause — not just the symptoms.
Unit Won't Turn On
Tripped breakers, failed capacitors, or bad control boards are common culprits. We test and replace failed components to get your system running again.
Short Cycling
If your system turns on and off every few minutes, it could be oversized, have a clogged filter, or a refrigerant issue. We find out exactly what's causing it.
Strange Noises or Smells
Banging, squealing, or burning smells are warning signs. We inspect blower motors, belts, heat exchangers, and electrical components to catch problems before they get worse.
Frozen Coils
Ice on your AC coils means reduced airflow or low refrigerant. We thaw the system safely and fix the underlying cause so it doesn't happen again.
High Energy Bills
A system working harder than it should drives up your energy costs. We check system efficiency, refrigerant charge, and duct performance to bring it back in line.
