6 Must-Know HVAC Maintenance Tips for a Reliable System

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 Professional HVAC Maintenance Twice a Year

Regular HVAC tune-up and maintenance keeps your system in top shape. Scheduling a professional checkup in the spring for your air conditioner and in the fall for your furnace helps prevent unexpected breakdowns during extreme weather. These routine inspections keep your system running efficiently, reduce the risk of costly repairs, and maintain a comfortable home year-round. For expert care, consider scheduling HVAC maintenance.

Spring AC Tune-Up

A spring HVAC tune-up prepares your air conditioner for the warmer months. A professional will check for any motor or electrical issues, clean components, and make adjustments to keep your cooling system working efficiently. Taking these steps early helps your AC handle the summer heat without stress.

Fall Furnace Tune-Up

Fall is the perfect time to schedule a HVAC tune-up and inspect your furnace before the colder weather hits. A professional will inspect the burner, heat exchanger, and other critical components to catch any issues before winter, helping your system run reliably throughout the season.

Replace the Filter Every Few Months

Changing your HVAC air filter regularly is one of the simplest ways to keep your system running efficiently. Even if the filter looks clean, it can still be clogged with dust and invisible particles that restrict airflow, making your HVAC system work harder.

Improve Airflow and Efficiency

A dirty filter limits airflow, causing your system to use more energy to maintain comfortable temperatures. Replacing the filter every few months reduces strain on the system, leading to smoother operation and potentially lowering your energy bills.

Boost Indoor Air Quality

Regularly changing the filter not only helps your HVAC system but also keeps your indoor air cleaner. A fresh filter traps dust, pollen, and allergens, which can improve the air quality throughout your home.

Clear Outside Debris

Debris like leaves, twigs, and trash can obstruct airflow, reducing the efficiency of your HVAC system. Keeping the area around your outdoor unit clear increases its performance and longevity.

Keep Plants Away from the Condenser

Plants growing too close to the condenser can block air movement and cause the unit to overheat. Trim or remove any plants encroaching on your HVAC unit to promote proper airflow. Aim to keep at least 12 inches of space around the coil for optimal ventilation.

Clean Dirt and Debris from the Unit

Turn off the HVAC unit and use a hose without a spray attachment to gently rinse off dirt and debris from the condenser. This simple step helps the system breathe better and function more efficiently.

Know the Best Temperature Settings

Setting your thermostat to 78 degrees in the summer and 68 degrees in the winter balances comfort and efficiency. These settings allow your HVAC system to maintain a comfortable environment without overworking, which can help reduce energy consumption and lower utility bills.

Summer Thermostat Setting: 78 Degrees

A 78-degree setting keeps your home cool while reducing strain on your air conditioner. This temperature is efficient for cooling without overexerting your system, helping to manage energy costs during the warmer months.

Winter Thermostat Setting: 68 Degrees

Setting the thermostat to 68 degrees during winter provides warmth without overheating your space. This setting balances comfort and efficiency, helping your furnace run smoothly through the colder months.

If your HVAC system struggles to maintain these temperatures, it may be time for a repair. Schedule HVAC repair to keep your system performing as it should.

Check the Flame

A healthy furnace flame should be a steady, crisp blue. This color indicates that the gas is burning efficiently and completely, keeping your system safe and running well. If the flame appears wavy, orange, or yellow, it could signal an issue that needs attention. In such cases, it's important to have a professional inspect the furnace. Schedule furnace repair if you notice any changes in the flame's color or behavior.

Clean the Condensate Drain Line

Knowing how to clean an AC drain line is important for preventing water damage. Condensate water from the evaporator flows through a drain line to avoid leaks, but over time, this line can become clogged with algae or 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 functioning properly.

Addressing System Issues

Even with regular maintenance, HVAC systems can sometimes experience problems. If your system is struggling or showing signs of trouble, schedule HVAC maintenance to keep it running efficiently.
