HVAC Experts: 4 Ways to Make Your AC Unit More Energy-Efficient

← Back to all articles

You don't need a new system to get more out of the one you already have. These four changes make a real difference in how efficiently your AC runs.

1. Seal the Gaps

Even a well-running AC has to fight a losing battle if conditioned air is leaking out around windows and doors. Check for gaps around window frames and reseal with caulk where it's cracked or missing. It's a small, cheap task that stops your system from cooling the outdoors along with your house.

2. Check Your Insulation

Insulation tends to be weakest in attics, and it's often overlooked because it's out of sight. Poor attic insulation lets summer heat radiate directly into your living space, forcing your AC to work harder just to keep up. If it's been years since anyone looked at your attic insulation, it's worth a check.

3. Get Your Thermostat Settings Right

Small, consistent adjustments matter more than dramatic ones. A programmable or smart thermostat that automatically adjusts when you're away or asleep saves energy without you having to remember to do it manually every day — and most people find they barely notice the difference in comfort.

4. Don't Skip Scheduled Maintenance

A dirty coil, a slightly low refrigerant charge, or a filter that's overdue for a change are all things a technician catches during routine maintenance — and all things that quietly drag down your system's efficiency if left alone. Annual maintenance is the single best thing you can do to keep your AC running the way it did on day one.

Put It Together

None of these four steps require touching your equipment budget. Sealed gaps, solid insulation, a well-programmed thermostat, and regular maintenance together can add up to a noticeably lower summer electric bill.
