We’ve already seen some sizzling days this summer—and chances are, the heat isn’t letting up anytime soon. If your air conditioner has been running nonstop, you might be wondering: Can it make it through the rest of the season without breaking down?
We know how hard your AC works to keep your Sacramento-area home cool. But without a few key check-ins, it could be one heatwave away from trouble. Below is our simple, late-summer AC survival checklist—plus a convenient reminder to stock up on air filters directly from our website to keep your system breathing easy.
1. Check and Replace Your Air Filter
One of the most important steps you can take to protect your AC is also one of the easiest: check your air filter. A dirty, clogged filter restricts airflow, forces your system to work harder, and can eventually lead to overheating or frozen coils. During heavy summer use, filters can clog much faster than you’d expect.
Pro tip: Change your filter every 30 days in the summer. If it’s dusty, gray, or caked with debris, it’s time for a new one. It’s better to change it out a little sooner than to leave it in place for too long and face repercussions.
2. Listen for Unusual Sounds
Is your AC making new noises—like banging, buzzing, rattling, or squealing? These are often early signs of worn-out components, loose parts, or electrical issues. Don’t ignore them. Catching the problem now could help you avoid a breakdown during the next triple-digit heatwave.
3. Feel the Air Coming From Your Vents
Place your hand over several vents throughout your home. Is the air cool and strong, or weak and warm? Inconsistent or warm airflow could signal:
- Low refrigerant levels
- A failing compressor
- Clogged ducts
- Dirty evaporator coils
Any of these require professional attention. Let us diagnose the issue before your system gives out completely.
4. Check the Outdoor Unit
Take a quick walk outside and inspect your condenser unit. It should be free from:
- Grass clippings
- Overgrown bushes or plants
- Dirt, leaves, and debris
Why it matters: Restricted airflow around the outdoor unit can reduce cooling efficiency and shorten your system’s lifespan. Gently hose off the unit and clear at least 2 feet of space around it.
5. Watch Your Energy Bills
If your power bills are higher than usual—and your thermostat settings haven’t changed—your system may be working harder than necessary. That’s a red flag for underlying problems like clogged filters, dirty coils, or an aging compressor.
6. Schedule a Late-Summer Tune-Up
Your AC might seem like it’s hanging in there—but that doesn’t mean it’s operating at full strength. A professional tune-up helps catch worn-out parts, improve energy efficiency, and ensure your system is ready to finish the season strong.
We’ll inspect, clean, and optimize your system to help it power through the last heatwaves without surprise breakdowns.
