6 Signs Furnace Trouble: Identifying Common Furnace Issues
🔥 How to Identify Furnace Trouble
1. Cold Air
Finding your home cold during winter can be incredibly frustrating, especially if your furnace is running. The blower motor might be the culprit. It's responsible for circulating warm air through your ducts. If malfunctioning, it won't heat your home properly.
2. Strange Noises
While some humming is normal, pops, squeaks, or rattling can signal issues. A possible cause is a malfunctioning blower wheel, which can trap debris, causing noise. Loosened mechanical parts can also create rattling sounds. Hire a local HVAC company to diagnose and fix the problem.
3. Increased Heat Bills
An inefficient furnace can spike energy bills. Check your filter first; if dirty, it may block airflow, forcing your furnace to work harder. Replace disposable filters every 2-3 months, or clean permanent ones with water and detergent.
4. Furnace Doesn’t Start
Older furnaces can be hard to start. If yours is newer, reset or troubleshoot the thermostat. Turn it to its lowest setting, switch the furnace off, then back on. If it heats, problem solved. If not, call a professional.
5. Water Leaks
Not dangerous but damaging, water leaks can ruin flooring and walls. They often occur when condensation lines clog. An HVAC repair pro can fix this and prevent future leaks with regular checks.
6. Yellow Pilot Light
Your furnace’s pilot light should be blue. Yellow signals a ventilation problem or gas leak, possibly carbon monoxide. Shut off your furnace and contact an HVAC technician immediately.
When to Replace Your Furnace
Signs like excessive soot, loud noises, or a yellow pilot light may mean it's time for a new furnace. Other indicators include increased humidity, unpleasant odors, and rust or cracks on the unit.
