Dos and Don’ts of Running Your AC in the Summer

When summer temperatures rise, your air conditioner becomes one of the most important appliances in your home. But using it the right way can make a big difference in both comfort and cost. Here are some essential dos and don’ts for getting the most out of your AC system during the hot months.

Do: Change Your Air Filter Regularly

Your AC unit works hard to keep your home cool, and a clean filter helps it do the job efficiently. When the filter is clogged, the system has to work harder, which means higher energy bills and more wear and tear. Change your air filter every one to three months, depending on usage and whether you have pets or allergies.

Don’t: Block Vents with Furniture or Rugs

It might seem harmless to place a sofa or rug over a vent, but this restricts airflow and can reduce your system’s efficiency. Keep all vents open and unobstructed so air can circulate properly throughout your home. This helps avoid hot spots and ensures even cooling.

Do: Use a Programmable Thermostat

A programmable thermostat allows you to set different temperatures for different times of the day. For example, raise the temperature when you're not home and cool things down just before you return. This smart move can save you money and prevent unnecessary strain on your system. Many homeowners who have upgraded to programmable thermostats report noticeable savings on their utility bills.

Don’t: Set the Thermostat Too Low Too Fast

When you walk into a hot house, it’s tempting to drop the thermostat way down to cool off quickly. But this doesn’t speed up the cooling process—instead, it forces your system to work overtime. Stick to gradual changes, ideally setting the temperature between 72–78°F for efficient cooling.

Do: Schedule Regular Maintenance

One of the smartest steps you can take is scheduling routine maintenance with a licensed HVAC technician. They’ll check refrigerant levels, clean coils, and make sure your unit is running smoothly. This not only extends the life of your system but also helps prevent mid-summer breakdowns. If you're unsure where to start, explore your AC services options to learn what’s available.

Don’t: Ignore Signs of Trouble

If you hear strange noises, notice weak airflow, or see your energy bill climbing, don’t wait. These are warning signs that your system might need attention. Acting early can save you from more expensive repairs down the road.
