AC Maintenance Mistakes That Could Cost You Big

by J&J on August 8, 2025

Mid-summer in Northeast Ohio can push your air conditioner to its limits - and one small mistake can lead to costly breakdowns, sky-high energy bills, or a home that's just too hot. At J&J Plumbing, Heating, Cooling & Electric, we've seen it all, and we want to help you avoid the most common AC maintenance mistakes homeowners make in July and August.

Here's what you should watch out for - and how to keep your system running smoothly all summer long.

1. Forgetting to Change the Air Filter

Why it matters: A clogged air filter restricts airflow, forcing your system to work harder and potentially overheat. It also reduces indoor air quality and increases energy use.

Fix it: Replace your filter every 30-60 days during heavy use months. Homes with pets or allergies may need even more frequent changes.

2. Blocking or Closing Vents

Why it matters: Closing vents in unused rooms might seem smart, but it can actually unbalance your system's airflow and cause pressure buildup.

Fix it: Keep all vents open and clear of furniture, rugs, or curtains to ensure proper circulation throughout your home.

3. Ignoring Strange Noises or Odors

Why it matters: Grinding, rattling, or musty smells are early warnings of bigger problems - like motor failure or mold buildup.

Fix it: Don't wait until it fails. Call J&J's expert HVAC team to inspect and resolve the issue before it escalates.

When your AC unit breaks down at the most inconvenient moment, you can trust our emergency air conditioning repair service for timely solutions.

4. Skipping Your Annual AC Tune-Up

Why it matters: Preventative maintenance is the best way to extend the life of your system and catch minor issues early.

Fix it: Comfort Club members at J&J receive scheduled inspections and cleanings that keep systems operating at peak performance.

5. Setting the Thermostat Too Low

Why it matters: Setting the thermostat to 65°F won't cool your home faster - it'll just overwork your system, waste energy, and increase wear and tear.

Fix it: Set it around 72-74°F for efficient comfort, and use ceiling fans to help circulate cool air.
