Frequently Asked Questions

Why does my AC capacitor fail so often in Frederick?

In Frederick, our power grid can experience voltage fluctuations, especially during peak summer demand. These spikes and dips put extra stress on the AC capacitor, which is responsible for starting the compressor and fan motors. Frequent cycling on very hot days accelerates wear. A professional tune-up from May's can check capacitor health and system voltage, helping to prevent unexpected failures.

How can I protect my outdoor AC unit from corrosion?

Frederick's humidity and winter weather can accelerate corrosion on your condenser coil and cabinet. The best protection is regular professional maintenance. Our technicians at May's will clean the coil to remove corrosive debris, check for early signs of rust, and ensure proper drainage. We can also apply protective coatings and recommend strategic placement or covers during the off-season to shield the unit.

What HVAC service is most important for Frederick homes?

For our local climate, bi-annual preventative maintenance is the most critical service. A spring tune-up prepares your AC for summer heat, checking capacitors and cleaning coils to prevent corrosion. A fall check-up ensures your furnace is safe and efficient for winter. This proactive approach from May's directly addresses our area's common issues, improving reliability, efficiency, and preventing the majority of emergency breakdowns.
