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.

When it comes to cooling in Pisgah Forest, the local conditions matter. 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. Our AC technicians understand these Pisgah Forest-specific factors and size every repair and recommendation accordingly.

Safety First: What to Check Immediately

Before troubleshooting a furnace that isn't working, check for any unusual smells. If you smell gas (rotten egg odor), leave the house immediately, don't flip any switches, and call your gas company from outside. If there's no gas smell, you can safely proceed with basic troubleshooting. Check your thermostat — make sure it's set to "heat" and the set temperature is above the current room temperature. Verify that the thermostat display is active and batteries are fresh.

The Three Most Common Furnace Fixes

First, check your air filter. A completely clogged filter restricts airflow to the point that the furnace overheats and shuts down on its high-limit safety switch. Second, find your furnace's power switch — it looks like a regular light switch, usually on or near the furnace — and make sure it's on. It's easily bumped off accidentally. Third, check the breaker panel for a tripped HVAC breaker. These three checks resolve a surprising number of "furnace not working" calls in Western North Carolina.

Understanding Furnace Lockout

Modern furnaces have built-in safety controls that lock the system out when something goes wrong. If your furnace tries to start — you hear clicking or see the ignitor glow — but then shuts down after a few seconds, it's probably in lockout mode. This happens when the flame sensor is dirty, the ignitor is failing, the gas valve isn't opening, or the pressure switch detects a venting problem. Many furnaces display error codes through LED flashes on the control board. Count the flashes and share that information with your technician — it speeds up diagnosis considerably.
