Mid-winter is not a good time for a home equipment breakdown! Keep these maintenance tips in mind to keep systems and appliances humming along nicely and improve your home’s energy efficiency.

Check the condition of your furnace air filter every month during the heating season. It is important to replace the filter when it gets dirty, usually once every three months. Homes with pets or smokers should have their filters changed more often.

Avoid freezing pipes and water damage

If you are leaving your home for long periods of time during the winter, do not turn your furnace completely off. If you do, water pipes could freeze and burst, causing flooding and extensive damage. Check your homeowner insurance policy for water damage exclusions and limitations during the heating season.

Test your backup generator

In case of a power outage or emergency, you will want to make sure your generator is in proper working condition.

  • Start and briefly run your generator (this should be done several times a year, even if there is no power outage). Rain, dirt, or brush entering the weathertight enclosure can cause mechanical and electrical issues with generators not in use.
  • Inspect and replace all fluids, spark plugs, alternator brushes and filters based on the manufacturer’s recommendations.
  • Check for loose, damaged, or missing parts – especially battery terminals and other electrical connections and wiring harnesses.

Dust your thermostat’s interiorThermostat

To eliminate any erratic operation, dust your thermostat’s interior and make sure to use the right size of batteries if applicable. There may be switches on your home thermostat’s base and near its temperature sensor, and those switches may loosen and corrode over time. Tighten loose connections with a screwdriver and use a cotton swab to clean away any corrosion.

Check for cracked and frayed wires, motor lubrication, refrigerant level check and efficiency verification. Check the air filter monthly. Replace every three months or whenever necessary. Keep the area around the inside heat exchanger clear of dust and obstructions. Dust can get into the blower motor and overheat it, causing premature failure.
