Signs Your Furnace Needs Repair
Furnace problems often start small before turning into full system breakdowns. Call us if you notice any of the following:
Weird or Persistent Smells
Burning dust is normal for the first run of the season — but lingering odors or sudden chemical smells indicate a problem.
Frequent Service Calls
If you’re calling 2–3 times per winter, your furnace is wearing out and needs attention.
Excessive Rust
Corrosion on the flue or furnace body may indicate dangerous venting issues or moisture damage.
Startup Problems
Clicking, slow ignition, or no heat at startup are signs of upcoming failure.
Loud or Strange Noises
Banging, rattling, squealing, or grinding noises mean something is failing internally.
Rising Utility Bills
A struggling furnace will work harder and use more gas or electricity.
Short Cycling
If your furnace constantly turns on/off, something is preventing normal operation.
If you notice any of these issues — or your home isn’t warming properly — we can help.
The Top Causes of Furnace Failure
These are the most common issues we find in San Diego homes:
Clogged Filters
Dirty filters restrict airflow and cause overheating, shutdowns, and higher energy bills.
Faulty Thermostats
A bad thermostat can prevent the furnace from turning on or heating properly.
Ignition Problems
Pilot light issues or failing ignitors will prevent your furnace from heating.
Exhaust Blower Issues
If the exhaust system fails, your furnace will shut down for safety.
Blower Motor Failure
Your furnace may heat — but without a working blower, warm air can’t circulate.
Damaged Heat Exchanger
Cracks or holes in the heat exchanger are dangerous and require immediate attention.
We repair all these issues and more — for every furnace brand and model.
