Well, the short, standard answer is once a year. But next time the HVAC tech is there, ask if thatís really necessary.
It could be that you have a newer furnace, your home is very clean, you have no pets, or your furnace and A/C arenít used all that much because you live in a temperate climate. You could possibly go two or three years between furnace tune ups.
What does a furnace tune up consist of?
- Cleaning components like the heat exchanger, combustion chamber, burners, jets, blower motor and fan, among other things.
- Checking and clearing the condensate lines. These lines drain not only water generated from gas combustion, they also drain condensation that collects on the A/C coil above the furnace.
- Doing a temperature differential test. That means measuring the temperature of the air going into and leaving the furnace.
- Performing a combustion analysis of the exhaust checking levels of O2, C/O and C/O2.
- Checking the ignitor and flame sensor for wear.
