Essential maintenance tips to keep your air conditioning running efficiently all summer long
As temperatures soar and summer approaches, your air conditioning system becomes your home's most essential appliance. But nothing's worse than your AC breaking down during a heat wave. The good news? Most breakdowns are preventable with proper maintenance.
In this comprehensive guide, we'll walk you through everything you need to know to prepare your AC system before the heat hits, ensuring optimal performance, energy efficiency, and avoiding costly emergency repairs.
Energy Savings with Proper Maintenance
Longer System Lifespan
Breakdowns Are Preventable
Your AC system has been dormant for months. During this time, dust accumulates, components settle, and minor issues can develop into major problems. Starting up your system without maintenance is like running a marathon without training—you're asking for trouble.
A well-maintained AC uses 15-30% less energy than a neglected one
Catch small problems before they become expensive emergencies
Clean filters and coils mean cleaner, healthier air for your family
Regular maintenance can double your system's operational life
Follow these essential steps to get your AC system summer-ready
Dirty filters are the #1 cause of AC inefficiency. They restrict airflow, making your system work harder and costing you money.
Pro Tip:
Check filters monthly during summer and replace every 1-3 months depending on usage. If you have pets or allergies, replace them more frequently.
Your outdoor unit needs to "breathe" properly. Remove debris, leaves, grass clippings, and dirt that accumulated during fall and winter.
How to clean it:
A clogged drain line can cause water damage, mold growth, and system shutdowns. This is especially important in humid climates.
Quick test:
Pour a cup of water into the drain pan. It should drain within seconds. If it doesn't, the line needs clearing.
To clear it:
Pour a mixture of 1 cup bleach and 1 cup water through the drain line, or use a wet/dry vac to suction out clogs.
Your thermostat is the brain of your AC system. Make sure it's reading temperature accurately and communicating properly with your unit.
Testing steps:
While DIY maintenance is important, a professional tune-up catches issues you can't see and ensures peak performance.
What a professional inspection includes:
Don't ignore these red flags—they could save you from a complete breakdown
Could indicate a failing compressor, clogged ducts, or blower motor issues. Don't wait—weak airflow gets worse quickly.
If your AC is blowing warm air, you likely have a refrigerant leak, compressor problem, or thermostat issue requiring immediate repair.
Grinding, squealing, or banging sounds indicate mechanical problems. Turn off your system and call a professional immediately.
Moisture or pooling water around your unit signals a blocked drain line or refrigerant leak. Both require immediate attention.
A sudden spike in your electricity bill means your AC is working overtime due to inefficiency or a developing problem.
If your AC turns on and off constantly (short cycling), it's a sign of a serious problem that will lead to premature failure.

Keep your home cool and your energy bills low with these expert strategies
The Department of Energy recommends 78°F when you're home and higher when away. Each degree above 78°F saves 3-5% on cooling costs.
Smart tip: Use a programmable or smart thermostat to automatically adjust temperature based on your schedule.
Ceiling fans create a wind-chill effect that makes you feel 4-6 degrees cooler. This allows you to raise your thermostat setting.
Remember: Fans cool people, not rooms. Turn them off when you leave the room.
Close blinds, curtains, or shades on south and west-facing windows during the hottest part of the day to reduce heat gain by up to 30%.
Upgrade idea: Consider blackout curtains or reflective window film for maximum heat reduction.
Check doors, windows, and ductwork for gaps. Sealing leaks can improve AC efficiency by 15-20% and save hundreds annually.
Quick fix: Use weatherstripping for doors and caulk for windows. Both are inexpensive and easy to install.
Run dishwashers, washing machines, and ovens during cooler evening hours. These appliances generate significant heat that your AC must work harder to overcome.
Alternative: Grill outdoors instead of using the oven, and air-dry dishes when possible.
$200 - $400
By implementing these energy-saving strategies along with proper AC maintenance, the average homeowner can save $200-400 per year on cooling costs.
Preparing your AC system before summer isn't just about comfort—it's about protecting your investment, saving money, and ensuring your family stays cool when temperatures soar.
