What's Included in an Annual Furnace Tune-Up
Furnace maintenance is your once-a-year opportunity to catch a failing component before it leaves you without heat on the coldest night of the year. Georgetown furnaces sit idle for six to seven months between heating seasons, and that idle period is exactly when carbon buildup, dust accumulation, and component degradation happen unnoticed.
Georgetown's furnaces get some of the lightest actual use of any climate in the country, often running only 60-90 days a year, which sounds like it should mean less wear. In practice, long idle periods create their own problems, oxidation, dust settling, and seals drying out, that a system used year-round doesn't experience the same way.
When to Schedule Furnace Maintenance
- It's fall and you haven't had the furnace serviced since last heating season
- You want to catch a flame sensor or ignitor issue before the first cold snap rather than during one
- Your furnace is under manufacturer warranty requiring documented annual service
- You moved into a home and don't have service history on the existing furnace
- You noticed reduced heat output or longer cycles than in previous winters
Our Furnace Maintenance Checklist
We clean the flame sensor and test its signal strength, inspect and test the hot surface ignitor, check gas pressure at the manifold, and run a combustion analysis to confirm the furnace is burning fuel safely and efficiently. We also inspect the heat exchanger for cracks, a critical safety check since a cracked exchanger can leak combustion gases into your living space.
We test the limit switch and rollout switch, both safety devices, to confirm they'll actually shut the system down if it overheats or a flame escapes improperly. Every finding is documented and explained so you know exactly what condition your system is in heading into winter.
We also check the condensate drain on high-efficiency furnaces during this visit, since a clogged condensate line can trigger a safety shutdown on these units even when every combustion-related component is functioning normally.
We leave you with a simple written summary of what was checked and any recommendations, so you have a clear record to reference even months later if a question comes up.
It also gives us a useful baseline to compare against on your next annual visit.
Consistent annual records like this also tend to support a stronger resale value story if you ever sell the home.
