Located just outside Brevard near the entrance to Pisgah National Forest, Pisgah Forest is a natural extension of our Transylvania County service area. Quality Comfort provides heating, cooling, and moisture management services to Pisgah Forest homeowners who face the unique challenges of living in one of the wettest areas in the eastern United States.

Pisgah Forest shares Transylvania County's extreme rainfall — averaging 70+ inches per year — making dehumidification a top HVAC priority. Homes near the Davidson River and Pisgah National Forest are heavily shaded by mature tree canopy, which reduces cooling loads but increases moisture problems and debris accumulation on outdoor units. Many properties here are older, with original ductwork running through damp crawl spaces that need remediation before HVAC upgrades will perform properly.

The 10 Most Common Reasons Your Air Conditioner Isn't Working

Air conditioner problems fall into predictable categories. Electrical issues (tripped breakers, blown fuses, dead thermostats) account for about 30% of service calls. Airflow restrictions (dirty filters, blocked vents, frozen coils) account for another 25%. Refrigerant problems make up about 20%, and mechanical failures (compressors, fan motors, capacitors) cover the rest. Understanding which category your problem falls into helps you decide whether it's a DIY fix or a professional repair.

Electrical Causes — Often a Quick Fix

If your air conditioner shows no signs of life, check the thermostat display first. If it's blank, replace the batteries or check the breaker that powers it. Next, find your main electrical panel and look for a tripped HVAC breaker — it'll be in a middle position between on and off. Your outdoor unit also has a disconnect box mounted on the wall near it; make sure that's in the on position. These simple checks resolve about one in five "my AC isn't working" calls in Asheville.

Refrigerant and Airflow Problems

If the system runs but doesn't cool, you may be dealing with low refrigerant from a leak or severely restricted airflow from a dirty filter or frozen evaporator coil. A frozen coil is especially common in WNC's humid climate — the combination of a slightly low refrigerant charge and high humidity creates ice buildup quickly. If you see ice on the refrigerant lines going to your indoor unit, turn the system off, set the fan to "on" to help it thaw, and call for AC repair.

Mechanical Failures

Fan motors, compressors, and capacitors eventually wear out. A humming outdoor unit that won't start often points to a bad capacitor — one of the most affordable repairs. A compressor that trips the breaker repeatedly may have a ground fault, which is a more serious issue. Quality Comfort's technicians use electrical testing equipment to pinpoint exactly which component has failed, so you're never paying for guesswork.
