Don’t Let These 7 Summer Cooling Mistakes Catch You Off Guard

As summer hits full swing here in New York, your home cooling system becomes one of the hardest-working systems in your home. That means you are likely to deal with one of these 7 summer cooling mistakes. But staying cool doesn’t have to mean higher bills, uneven temperatures, or breakdowns in the middle of a heatwave.

Many homeowners make small mistakes that can cost big over time. Here are 7 summer cooling mistakes to watch out for this July, plus a few smart ways to use summer’s warmth to get ahead on winter prep.

1. Cranking the Thermostat Too Low

Hot days can tempt anyone to drop the thermostat to 70°F or lower, but doing so won’t cool your home faster. It only forces your system to run longer, using more energy and putting added strain on the compressor.

Smart tip: Keep it set to 78°F when you’re home, and pair it with a ceiling fan to improve air circulation and comfort.

2. Skipping Seasonal HVAC Maintenance

We get it, summer moves fast, and AC maintenance might not be top of mind. But without a professional tune-up, minor issues like low refrigerant or dirty coils can quickly turn into major repairs.

Stay ahead: Annual service keeps your system efficient, helps catch issues early, and gives you peace of mind.

Good and Bad Furniture Placement

3. Blocking Vents Without Realizing It

Furniture, rugs, or curtains can accidentally block air vents, making some rooms feel warmer and putting extra strain on your AC.

Quick check: Walk through each room to make sure vents and returns are clear and free of obstructions.

4. Wasting Energy Through Leaky Doors and Windows

Cool air escapes easily through unsealed cracks, forcing your system to work harder. It’s a common culprit behind rising energy bills.

Fix it fast: Add weatherstripping or caulk to windows and doors. You can also use insulated curtains to reduce solar heat gain.

5. Ignoring Indoor HumidityWK Mechanical technician holding out a clear air filter for the home owners - Summer Cooling Mistakes

 

Humidity is part of summer in the Hudson Valley. If your home feels clammy or warmer than it should, moisture might be the issue, not temperature.

Try this: A whole-home dehumidifier or upgraded thermostat settings can help maintain a dry, comfortable indoor climate.

6. Overlooking Filter Changes (and What They Reveal)

Yes, changing your air filter is key to efficiency, but it also indicates the air quality in your home. If filters clog quickly, it could mean you have duct leaks, poor circulation, or hidden debris buildup.

Helpful habit: Check your filter monthly in summer. If it’s dirty, swap it out! You can shop for filters and more with us at www.WKMechanical.com/Shop.

7. Missing the Opportunity to Prep for Colder Months 

Here’s something most homeowners don’t think about in July: prepping your heating system while it’s warm.

  • Summer is the ideal time to schedule boiler or furnace inspections, before everyone else calls in the fall.
  • It’s also the perfect season to insulate attics or seal crawl spaces, which helps with both cooling and heating costs.
  • If your system is older or inefficient, use this summer to explore heat pump upgrades or hybrid systems while rebates are still available.
