HVAC Repair Mountain Grove MO | Call Shannon Heating & Cooling

It very well could be. Dirty condenser coils are a common issue here, as pollen, grass clippings, and dust can quickly build up on your outdoor unit. This buildup acts like insulation, trapping heat and forcing your AC to work much harder, which reduces cooling power and increases your energy bills. A professional cleaning from our team can restore efficiency and prevent strain on the entire system.

A failed start capacitor is one of the most frequent causes of a non-starting AC unit, especially during our hot summers when the system is under the most stress. The capacitor provides the necessary jolt to start the compressor and fan motors. When it fails, you might hear a humming sound from the unit but no start. We can quickly test and replace a faulty capacitor to get your cool air flowing again, often the same day.

We strongly recommend bi-annual preventative maintenance—once in the spring for your cooling system and once in the fall for your heating system. Our comprehensive tune-up includes cleaning those vulnerable condenser coils, checking capacitors and electrical components for wear, testing refrigerant levels, and ensuring all parts are in good working order. This proactive care helps catch small issues before they become expensive, inconvenient breakdowns during peak season.
