Skipping the tune-up this year? Here is what tends to follow.

Systems that go unserviced work harder for the same output, which shows up on your utility bill before it shows up anywhere else. Small issues that a technician would have caught become breakdowns, usually during the first stretch of cold weather. And with gas systems specifically, there are safety checks that simply do not happen if nobody looks.

There is still time to get on the schedule this month. Call (931) 647-9610.

A tune-up is more than a quick look around. Here is what the visit actually covers:

▪️ Inspecting the heat exchanger, burners, and ignition system
▪️ Checking electrical connections and testing safety controls
▪️ Cleaning components that collect dust over the off-season
▪️ Measuring airflow and verifying the system performs the way it should

The goal is finding the small problem in October instead of the expensive one in January.

Everything a visit includes is laid out at mainstreamac.com/services/heating.
