Goodbye summer… It’s officially fall! As those warm San Diego days give way to cooler nights, there’s something crucial every homeowner needs to know: Your furnace has been sitting idle all summer, and it needs attention before you flip that switch.
Your Furnace: The Controlled Fire in Your Home
Let’s talk about something most San Diego homeowners don’t think about until it’s too late. Your furnace is essentially a controlled fire tucked away in your attic, garage, or closet. After 70 years of keeping San Diego homes safe and comfortable, we’ve seen what happens when homeowners wait until the first cold snap to discover there’s a problem.
Here’s what our White Glove technicians want every homeowner to understand: A neglected furnace isn’t just an inconvenience—it’s a genuine safety risk.
The Hidden Dangers Lurking in Your Furnace
- Carbon Monoxide Risk: A cracked heat exchanger or blocked vent can release this odorless, deadly gas into your home
- Fire Hazards: Dust accumulation near the pilot light or electrical components can ignite
- Gas Leaks: Corroded connections or worn valves may develop leaks over the summer months
- Electrical Failures: Rodents seeking shelter can damage wiring during the off-season
Why Your Furnace Needs Attention NOW
Your air conditioner and furnace aren’t separate systems—they share critical components including the blower motor, air handler, and ductwork. After a long, hot San Diego summer of continuous AC use, these shared components are already under stress.
Think about it: Your system has been working overtime since May, pushing cool air through your home day after day. The blower motor bearings may be worn, the air filter is likely clogged with summer dust and pollen, and electrical connections may have loosened from constant vibration.
This is exactly why September and October are prime time for furnace maintenance—before you actually need the heat.
The Silent Summer: What Happens When Your Furnace Sits Idle
Pest Intrusion
Rodents and insects seek shelter in warm furnace cabinets, potentially damaging components and creating fire hazards.
Moisture Damage
San Diego’s marine layer brings humidity that can corrode metal components and damage electrical connections.
Dust Accumulation
Months of dust settles on burners and heat exchangers, creating efficiency problems and potential fire risks.
Component Deterioration
Rubber belts dry out, metal parts develop surface rust, and safety switches may fail without regular operation.

Frequently Asked Questions
How often should I have my furnace serviced?
We recommend annual furnace maintenance, ideally in early fall before you need to use your heating system. This ensures safe operation, maintains efficiency, and helps prevent unexpected breakdowns during cold weather.
What are signs my furnace needs immediate attention?
Call us immediately if you notice: gas odors, yellow or flickering pilot light (should be blue), unusual noises (banging, squealing, rattling), frequent cycling on and off, unexplained increase in gas bills, or any signs of soot around the furnace.
Is furnace maintenance really necessary in San Diego's mild climate?
Absolutely! While we don’t face harsh winters, our furnaces sit idle for months, accumulating dust and potentially developing problems. The marine layer brings moisture that can corrode components, and our occasional cold snaps can stress an unmaintained system.
