It might seem like you were just enduring the hot, sticky days of summer, but winter is already right around the corner in Hagerstown, Maryland. Since you’ll want to keep your air conditioner in great shape for next summer, take a few minutes to shut down your cooling system properly. From changing the filter to scheduling a tuneup, use this maintenance checklist to prepare your air conditioner for the winter cool-down.

Change the HVAC Filter

If you haven’t changed your HVAC filter for over a month, replace it now — even if you plan to run your air conditioner only for another week or two. HVAC filters keep your indoor air quality high and your cooling system clean, so keeping the filter fresh is essential. At Griffith Energy Services, we recommend changing the filter every 30 days, especially during the sweltering summer months.

Switch the Thermostat Settings

Ready to switch the air conditioner off for the season? With a smart thermostat, making the change couldn’t be easier. Simply switch from cool mode to off or go straight to heat mode. When it’s time to turn on your furnace, be sure to set your thermostat to 68 degrees, and program it to dial back the temperature up to 10 degrees overnight.

Cover the Outdoor Unit

Covering your outdoor air conditioner unit is a smart move, as protecting the unit during the winter can keep snow and ice from damaging it. Be sure to turn the power off before placing a waterproof or plastic cover over the unit, and you’ll keep it safe until next spring.

Schedule Maintenance in Advance

Our air conditioner technicians recommend scheduling maintenance as early as possible in the season. That way, your cooling system will be good to go as soon as the weather starts to heat up. Talk with our team about an HVAC service plan now to make sure you don’t miss a beat in the spring.
