M H Confort: Certified HVAC Repair Serving Memphis, TN 38128

Common signs include your outdoor AC unit humming but not starting, frequent system cycling on and off, or a complete failure to cool. In Memphis' intense summer heat, HVAC systems run constantly, putting immense strain on the capacitor. This component is like a battery that gives your compressor and fan motors the extra jolt to start. The constant stress during our long cooling season makes it one of the most frequent failure points we see.

A dirty evaporator coil acts like a clogged filter inside your air handler. It can't absorb heat from your home's air efficiently, forcing your system to run much longer to reach the set temperature. This leads to poor cooling, higher humidity indoors, and a significant spike in your monthly energy costs. Given Memphis' humidity, a clean coil is crucial for both comfort and efficiency. Regular professional maintenance can prevent this buildup.

First, check your thermostat settings and air filter, as a clogged filter can restrict airflow. If those are fine, the issue could be a failing capacitor, a refrigerant leak, or a frozen evaporator coil—often caused by the dirt and humidity issues common here. To prevent further damage, turn the system off at the thermostat and call a professional like M H Confort. While you wait, keep blinds closed to reduce heat gain and use fans to circulate air. Avoid repeatedly trying to restart the unit, as this can cause further damage. We offer prompt emergency service to diagnose the issue, which is often a failed capacitor or a refrigerant problem.
