Here are some tips for protecting your HVAC system during the winter months, from the perspective of a service technician:
Change your air filter regularly: A dirty air filter can restrict air flow and cause your system to work harder, which can lead to breakdowns. Make sure to change your air filter every 1-3 months, depending on the type of filter and the conditions in your home.
Keep your thermostat at a consistent temperature: Turning your thermostat up and down frequently can put a strain on your system and reduce its efficiency. Try to keep your thermostat set to a consistent temperature to help prolong the life of your HVAC system.
Clear debris from around your outdoor unit: Snow, ice, and leaves can accumulate around your outdoor unit and block the air flow. Make sure to clear away any debris to ensure that your system is running efficiently.
Insulate your home: Proper insulation can help to keep the heat in your home and reduce the workload on your HVAC system. Make sure to check the insulation in your attic, walls, and crawl spaces to ensure that it is sufficient.
Have your system serviced regularly: Regular maintenance can help to catch problems before they turn into major breakdowns. Make sure to schedule a service appointment at least once a year to have your system inspected and cleaned.
Consider installing a programmable thermostat: A programmable thermostat can help you save energy and money by allowing you to set different temperatures for different times of the day.
I hope these tips help you protect your HVAC system during the winter months!
