When it comes to cooling in Brevard, the local conditions matter. Transylvania County earns its 'Land of Waterfalls' nickname with some of the highest rainfall in the eastern US — averaging 80+ inches annually. This extreme moisture makes dehumidification a year-round priority. Crawl spaces in Brevard homes are especially prone to moisture damage that can corrode ductwork and foster mold growth in HVAC systems. Our AC technicians understand these Brevard-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.
