HVAC Services Durham NC | Call Shepherd Heating & Air Conditioning

This is a common question for aging systems in our area. We recommend a thorough diagnostic evaluation. Often, a strategic repair or maintenance service can extend the life of a well-maintained unit. However, if repairs are frequent or a major component fails, replacing it with a modern, energy-efficient model can provide better reliability and lower monthly bills, especially during our hot summers. We'll provide a clear, honest assessment with all options.

Absolutely. A failed capacitor is one of the most frequent causes of sudden AC breakdowns in Durham's heat. The capacitor helps start the compressor and fan motors, and the strain of constant cycling can cause it to fail. While it's a common repair, it requires a professional for safe handling and correct diagnosis to ensure there aren't other underlying issues. We offer prompt emergency service to get your cooling restored quickly.

Preventative maintenance is key to avoiding breakdowns. For Durham homes, we focus on seasonal check-ups that include cleaning coils (vital for humidity control), checking refrigerant levels, inspecting and testing electrical components like capacitors and contactors, and ensuring the system is cycling properly. This proactive care helps aging systems run more efficiently, catches small issues before they become big repairs, and is the best defense against a sudden failure on the hottest day.
