We diagnose on-site and quote before starting. ### Compressor Failure The most expensive repair. We'll confirm it and walk you through repair vs. replacement options, including same-day financing. ### Electrical/Control Board Capacitors, contactors, and control boards fail without warning. They are fast fixes but require a licensed technician to diagnose safely. ### Refrigerant Leak Running but not conditioning air? We locate the leak, repair it, and recharge the system to manufacturer specs. ### Reversing Valve Failure Allows the system to switch between heating and cooling. When stuck in one mode, it's repairable, not a death sentence for the system. ## What to Do Before We Arrive These six steps take five minutes and can prevent further damage or sometimes solve the problem entirely! ### 1. Check your thermostat Make sure it's set to the correct mode and confirm the set point is at least 2-3°F different from the current room temperature. ### 2. Check your air filter A clogged filter is the #1 cause of heat pump problems. If it's visibly dirty, replace it before calling. Sometimes that's all it takes! ### 3. Check your circuit breaker Look for a tripped breaker labeled for the heat pump or air handler. Reset it once. If it trips again, stop and call us. ### 4. Clear the outdoor unit Make sure nothing blocks airflow such as leaves, ice, furniture, or overgrown vegetation. ### 5. Turn the system off if you hear grinding, or smell burning Running a compromised system causes further damage. Set the thermostat to "off" and call us. ### 6. Note what you observed Note the time the problem started, any unusual sounds, and how the system behaved. This helps our technician diagnose faster. ## How Air Comfort Service Handles Your Emergency Call ### Live Answer You reach a person around the clock ### Fast Dispatch Local techs in St. Louis, service within 24 hours. ### On-Site Diagnosis Full assessment of your system before any work begins ### Upfront Quote You approve the cost before we touch anything, no surprises ### Repair and Confirm We fix it, test it, and walk you through what we did ## [ Should You Repair It or Replace It? ](https://www.aircomfortservice.com/repairorreplace/ "Should You Repair It or Replace It?") ## Emergency Heat Pump Repair Across the St. Louis Metro Not sure if we cover your area?[ Click here](https://www.aircomfortservice.com/our-service-areas/) to see our entire service area page. ## FAQ Q: What heat pump brands do you service? **A**: All major brands.
