Your HVAC system works year-round to keep your home comfortable, but without regular maintenance, its efficiency can drop, energy bills can rise, and unexpected breakdowns can occur. Seasonal maintenance is essential to ensure smooth performance, lower costs, and extend its lifespan. This guide outlines key tasks for each season to keep your system running at its best.

Spring: Prepping for the Heat

As the frost thaws and temperatures begin to climb, it’s time to shift focus from heating to cooling. Preparing your air conditioner before the first heatwave hits is crucial for a comfortable and efficient summer.

Clear the Way for Cool Air

Your outdoor A/C unit (the condenser) has likely accumulated leaves, dirt, and other debris over the winter. This buildup can restrict airflow, forcing your system to work harder and use more energy.

• Action: Start by turning off the power to the unit at the circuit breaker. Then, clear away any leaves, branches, or grass that are within a two-foot radius of the condenser. You can gently hose down the exterior fins to wash away dirt, but avoid using a high-pressure nozzle that could cause damage.

Inspect and Clean the Coils

The condenser and evaporator coils are essential for heat exchange. When they’re caked in grime, they can’t cool your home effectively.

• Action: After cleaning the exterior, you can carefully remove the top grille to access the inside. Use a soft brush or a vacuum with a brush attachment to gently clean the fins. For a deeper clean, you can use a commercial coil cleaner, following the product’s instructions carefully.

Test Your A/C

Don’t wait for a 90-degree day to find out your air conditioner isn’t working.

• Action: Once everything is clean and reassembled, turn the power back on. Set your thermostat to “cool” and lower the temperature. Let the system run for 10-15 minutes to ensure it’s blowing cold air and that there are no unusual noises or odors. If something seems off, it’s time to call a professional.

Summer: Maintaining Peak Efficiency

With summer in full swing, your A/C is working its hardest. The goal now is to maintain its efficiency and prevent strain on the system during peak usage.

The Importance of a Clean Filter

A clogged air filter is one of the most common causes of HVAC problems. It restricts airflow, making your system work overtime to cool your home, which increases energy consumption and can lead to premature system failure.

• Action: Check your air filter at least once a month during the summer. If you have pets, allergies, or live in a dusty area, you may need to check it more frequently. Replace it as soon as it looks dirty. A clean filter is one of the easiest and most affordable ways to keep your system healthy.

Calibrate Your Thermostat

An inaccurate thermostat can cause your system to run unnecessarily or fail to cool your home adequately.

• Action: A simple way to check your thermostat’s accuracy is to place a glass of ice water next to it for about 30 minutes, with a thermometer inside the glass. Your thermostat should read close to the thermometer’s temperature. If it’s off by more than a few degrees, it may need recalibration or replacement. Consider upgrading to a programmable or smart thermostat to automatically adjust temperatures and save energy.

Autumn: Getting Ready for the Cold

As the leaves change color, your HVAC needs will shift from cooling to heating. Preparing your furnace or heat pump now will ensure you’re ready for the first cold snap.

Test Your Heating System

Just as you tested your A/C in the spring, it’s wise to test your heater before you actually need it.

• Action: Switch your thermostat from “cool” to “heat” and set the temperature a few degrees above the current room temperature. Let the system run to confirm it’s producing warm air. You might notice a slight burning smell the first time you turn it on; this is usually just dust burning off the heating elements and is normal. If the smell persists or you hear strange noises, turn the system off and schedule a professional inspection. For issues like this, consider air conditioning services like those offered in Herriman to ensure your system is running smoothly.

Clean Your Vents and Ducts

Over time, dust, pet dander, and other allergens can accumulate in your ductwork and get circulated throughout your home every time the system runs.

• Action: Vacuum your air vents and return-air grilles to remove dust buildup. For a more thorough cleaning, consider a professional duct cleaning service every few years, especially if you have family members with allergies or respiratory issues.

Winter: Ensuring Reliable Warmth

Winter puts the most strain on your heating system. The focus during these cold months is on preventing breakdowns and maximizing warmth and efficiency.

Prioritize Furnace Maintenance

A malfunctioning furnace can be more than an inconvenience—it can be a safety hazard, posing risks of carbon monoxide leaks.

• Action: Ensure your carbon monoxide detectors are working and have fresh batteries. Listen for any unusual sounds like banging, rattling, or squealing, which could indicate a problem with the blower motor or other components. Keep the area around your furnace clear of clutter to ensure proper airflow.

Check Your Home’s Insulation

Even the most efficient furnace will struggle if your home isn’t properly insulated. Heat can escape through attics, crawl spaces, and gaps around windows and doors.

• Action: Visually inspect the insulation in your attic to ensure it’s evenly distributed and not compressed. Use weatherstripping or caulk to seal any air leaks around windows and doors. This simple step can significantly reduce your heating costs and improve overall comfort.

Conclusion

Regular professional HVAC tune-ups are essential for maintaining efficiency and preventing costly issues. Certified technicians can inspect, tune, and identify problems in your system. Schedule a tune-up twice a year—spring for A/C and fall for heating—to ensure your system runs smoothly and lasts longer. Combine this with routine maintenance for year-round comfort.
