Summer Maintenance Tips to Avoid Unexpected HVAC Repairs

Summer means warm weather, outdoor fun, and, of course, relying on your HVAC system to keep your home cool and comfortable. But without proper maintenance, your system could be at risk for unexpected repairs right when you need it most. To help you avoid breakdowns, we've compiled a list of simple maintenance tips to keep your HVAC system running smoothly all season long.

1. Replace Your Air Filters

One of the easiest and most effective ways to maintain your HVAC system is by regularly changing the air filters. Over time, filters collect dust, dirt, and allergens, which block airflow and force your system to work harder. Check your filters monthly and replace them every 1–3 months, depending on usage and the manufacturer's recommendations.

Why It Matters

Clean filters improve airflow, boost efficiency, and reduce wear and tear on your system, saving you money on repairs in the long run.

2. Clean Around the Outdoor Unit

Your HVAC system's outdoor unit (or condenser) plays a key role in keeping your home cool. Over time, it can become obstructed by debris like leaves, grass, and dirt. Clearing away this debris ensures the unit has proper airflow and doesn't overheat.

Maintenance Tip

Trim back any vegetation within two feet of the unit to ensure unrestricted airflow. Also, gently hose off the unit to clean the fins, but avoid using high water pressure, which can damage them.

3. Inspect Your Thermostat

Your thermostat directly impacts how efficiently your HVAC system operates. Make sure it’s working properly by testing the temperature settings. If you’re still using a manual thermostat, consider upgrading to a programmable or smart thermostat. These devices optimize energy use by adjusting the temperature when you’re away or sleeping.

Bonus Savings

A well-programmed thermostat can significantly lower your energy bills while keeping your home comfortable throughout the day.

4. Check and Seal Ductwork

Leaky ductwork can cause your cool air to escape, leading to higher energy bills and uneven cooling in your home. Inspect your ducts for any visible gaps, holes, or disconnected sections. Use foil-backed tape or duct sealant to patch up leaks.

Why Act Fast?

Even small leaks can cause your HVAC system to work harder than necessary, increasing your utility costs and straining the system over time.

5. Schedule a Tune-Up

While DIY maintenance goes a long way, annual professional tune-ups are essential to catch potential problems early. An HVAC professional can clean internal components, check refrigerant levels, and ensure everything is functioning efficiently. Regular tune-ups can extend the lifespan of your system and reduce the risk of breakdowns.

When to Schedule

Spring or early summer is the ideal time for an HVAC tune-up to ensure your system is ready for peak performance in hotter months.
