Maintenance
A tune-up is worth it when
- It's been more than a year since the system was serviced
- Heating or cooling season is about to start
- The system is louder than it used to be
- Bills are creeping up
- You just moved in and don't know the service history
- Your manufacturer's warranty expects regular maintenance
Three things you can do yourself
- Change the filter every one to three months.
- Keep leaves, grass, and anything else at least two feet from the outdoor unit.
- Keep supply vents and return grilles open and clear.
Checked those and it’s still acting up? Call or text (573) 797-5242.
What a tune-up typically looks at
Electrical parts
Connections, capacitors, and contactors, which are behind many no-start calls.
Burners and ignition
Igniter, flame sensor, and burners on a furnace.
Coils
Indoor and outdoor coils that need to be clean to move heat.
Condensate drain
A clogged drain is a common cause of water leaks and summer shutdowns.
Refrigerant performance
Operating pressures and temperatures that show whether the system is cooling the way it should.
Thermostat and safety controls
The controls that start, stop, and protect the system.
When to schedule
The best time is just before the season you need it: furnace in the fall, air conditioner in the spring. That way a worn part gets found on a mild day instead of the coldest or hottest one.
