What We Check Every Tune-Up
The Real Cost of Skipping Furnace Maintenance
Fresno winters are mild compared to the Midwest, but that doesn't mean skipped maintenance is safe. Central Valley furnaces are typically idle from April through October — that's six months for dust, insects, and moisture to affect internal components. When you fire up the system in November, you're trusting it to work after months of no use.
- ✓Carbon monoxide risk — a cracked heat exchanger can allow CO into your home's air supply. Annual inspection catches this before it becomes a life-safety issue.
- ✓The November breakdown — the first cold week of the year is when untreated systems fail and every HVAC company is fully booked for days.
- ✓Dirty burners cost money — carbon buildup reduces combustion efficiency, increasing your gas bill every month without you noticing.
- ✓Warranty protection — most furnace manufacturers require documented annual maintenance to keep the warranty valid.
Furnace Maintenance FAQ
September or October — before the heating season begins. This ensures your system is ready when you need it and avoids the November–December rush when appointments fill weeks out.
Once per year is the standard recommendation. A furnace that runs frequently (gas heat with very cold winters) may benefit from mid-season checks, but in Fresno's mild winters once annually is generally sufficient.
Yes. Carbon monoxide is colorless, odorless, and potentially fatal. A cracked heat exchanger — which can develop gradually over years — can leak combustion gases into your home's air supply. We include a CO test on every maintenance visit because it's the right thing to do, not because it costs extra.
Between 60 and 90 minutes for a standard gas furnace. High-efficiency condensing furnaces with more components may take slightly longer. You'll receive a written inspection report before the technician leaves.
Homeowners can and should replace filters regularly and keep the area around the furnace clear. However, gas pressure testing, heat exchanger inspection, combustion analysis, and CO testing require equipment and training that go well beyond DIY scope — and mistakes can be dangerous.
