End of Summer Tips for Maintaining Your AC System

Here are some essential end-of-summer tips from the experts at Thomas Hoffmann Air Conditioning & Heating to keep your AC in top shape:

Schedule a Professional Inspection and Tune-Up

While DIY maintenance is important, nothing beats a thorough inspection by a trained HVAC technician. Our professionals can:

• Check refrigerant levels and look for leaks
• Clean or replace air filters
• Inspect and clean evaporator and condenser coils
• Check electrical connections and components
• Lubricate moving parts
• Ensure proper airflow
• Verify thermostat accuracy

Scheduling a tune-up now can help identify any issues before they become major problems next summer.

Clean or Replace Air Filters

One of the simplest yet most crucial maintenance tasks is keeping your air filters clean. A dirty filter restricts airflow, reducing efficiency and potentially causing your system to work harder than necessary. As summer ends:

• Check your filter monthly
• Clean reusable filters or replace disposable ones as needed
• Consider upgrading to a higher-quality filter for better air quality

Clear Debris Around the Outdoor Unit

Your AC’s outdoor condenser unit needs proper airflow to function efficiently. After a long summer, it may be surrounded by leaves, grass clippings, or other debris. Take time to:

• Clear a 2-3 foot area around the unit
• Gently clean the unit’s exterior with a garden hose
• Trim back any encroaching vegetation

Clean the Condensate Drain Line

The condensate drain line removes moisture from your AC system. Over time, it can become clogged with algae or mold, potentially causing water damage or system malfunctions. To clean it:

• Locate the drain line (usually a PVC pipe near the outdoor unit)
• Pour a cup of white vinegar or bleach solution down the line
• Flush with water after 30 minutes

Check and Clean Vents and Registers

Ensure all your home’s vents and registers are open and unobstructed. Vacuum any visible dust and check for signs of mold or excessive moisture.

Consider Upgrading Your Thermostat

If you haven’t already, consider upgrading to a programmable or smart thermostat. These can help optimize your HVAC system’s performance and save on energy costs year-round.

Address Any Lingering Issues

If you notice any problems with your AC during the summer (strange noises, inconsistent cooling, higher energy bills), now is the time to address them. Don’t wait until next summer when you’ll be relying heavily on your AC again.

Prepare for the Off-Season

If you won’t be using your AC for several months:

• Give it one last run to ensure it’s working properly
• Clean the area around the outdoor unit
• Consider using a weatherproof cover for the outdoor unit (but check manufacturer recommendations first)
