6 HVAC Maintenance Tips

A little upkeep can go a long way. Sears’ infographic shows how to make the most of your heater and air conditioner.

Your heating and cooling system should never let you down. To make sure it does its job right, you’ll need to give it a dose of TLC every now and again.

Andrew Daniels, Sears HVAC expert, offers up these tips to make sure your HVAC system works no matter the season — just as it should.

Schedule a Checkup Twice a Year

Timing is everything when it comes to HVAC maintenance. Having a Sears Home Services expert check your air conditioner in the spring and your furnace in the fall is the best way to prevent failures during extreme temperatures. By scheduling these check-ups, you're not just preventing the discomfort of a too-hot or too-cold home; you're also optimizing your system's efficiency and avoiding the financial strain of emergency repairs.

Replace the Filter Every Few Months

You might glance at your HVAC air filter and think, "Looks clean enough!" but don't be fooled. Regularly changing your air filter is a small task that packs a big punch. Even if the filter doesn't appear dirty, it can still be clogged with invisible particles that impede airflow and make HVAC system work harder. Plus, a clean filter maintains indoor air quality, trapping dust, pollen, and other allergens.

Clear Outside Debris

Debris like leaves, twigs, and even trash can obstruct the airflow, making it harder for your unit to function efficiently. Plants that crowd the condenser can also restrict air movement and lead to overheating. Cut or remove plants that are encroaching on your condenser so it can pull fresh air from all sides. Make sure to allow for at least 12 inches of space around the coil.
TIP: Turn off the unit and use a hose (with no spray attachment) to wash off dirt and debris.

Know the Best Temp

Setting your thermostat to 78 degrees in the summer and 68 degrees in the winter strikes the perfect balance between maintaining comfort and optimizing efficiency. At these temperatures, your HVAC system doesn't have to work overtime, which can significantly reduce your energy consumption and lower your utility bills. In the summer, a 78-degree setting allows your air conditioner to cool your home effectively without overexerting itself, while in the winter, setting the thermostat to 68 degrees provides enough warmth to be comfortable without overheating your space.

Check the Flame

A healthy furnace flame should be a nice, crisp blue color. This indicates that the gas is burning efficiently and completely. If you notice the flame is wavy, orange or yellow, have a Sears technician inspect the furnace.

Clean the Condensate Drain Line

Condensate water from the evaporator drains away down a drain line to prevent leaks spilling from the evaporator pan. Over time it can become clogged with algae and other debris. Every three months, pour a solution of 1 cup bleach and 3 cups water down the condensate drain tube to keep it clear and prevent possible water damage.

Even with the most diligent routine maintenance, HVAC systems can falter. When your heating or cooling system shows signs of trouble, lean on the trusted expertise of Sears Home Services and schedule repair.
