It’s essential to have your furnace tuned up every fall for a number of reasons. It will perform more efficiently, keep the furnace under warranty, and prevent repair expenses among other things. But what are the tasks a technician does during a furnace tune-up?


The insides of furnaces need to be cleaned. This keeps them operating efficiently and improves your indoor air quality. Our technicians will thoroughly clean critical parts by removing dust, dirt, pollen, and other debris.

Adjust Gas Pressure

The gas pressure being fed to your furnace can become too low or high over time. This prevents it from operating efficiently and keeping your home comfortable. Our technicians will check for gas leaks, so your home is safe.

Electrical Connections

Electrical connections can become loose over time, which causes problems. Loose electrical connections are also a fire hazard. Our technicians will make sure your electrical connections are tight and fix any that aren’t.

Test Safety Systems

Your furnace has multiple safety systems to ensure it is operating correctly and safely. Our technicians will check these systems to ensure they are working effectively so that your family stays safe. This includes checking that carbon monoxide isn’t leaking into your home. Carbon monoxide gas can make you sick or even cause fatalities.

Check Vent System

If you have a gas furnace, which most people do, it has a vent system to exhaust dangerous gases outdoors. Our technicians will make sure the vent system is clear of obstructions and leaks.

Lubricate Moving Parts

Finally, our technicians will examine and lubricate all moving parts to reduce wear and tear. This includes belts and motors.
