Before the first cold snap, take a few minutes to make sure your heating system is ready.
What you can do yourself
- Replace or clean the furnace or air-handler filter.
- Clear leaves and debris around the outdoor heat pump unit.
- Test your thermostat in heating mode.
- Check that supply and return vents are not blocked by furniture.
- Test carbon monoxide detectors.
What a technician should check
A professional tune-up includes combustion and safety checks on gas equipment, refrigerant and electrical checks on heat pumps, and cleaning of critical components. Regular maintenance also helps keep your warranty valid.
