Hot Weather Preparation

• Keep grass clippings and leaves away from the outdoor unit. This keeps dirt and debris from getting into the system. It also keeps the airflow path clear.
• Keep furniture and carpeting away from grills and ductwork. If you block your air conditioning system’s ability to deliver air, you rob yourself of the cooling necessary to keep your home comfortable.
• Keep the west-facing drapes, shades or blinds drawn in the afternoon. Keeping the sun out will keep your home cooler.
• Run your dishwasher, washing machine and dryer in the evening hours.
• Don’t use your oven.
• Keep your fan running. It helps to keep the air moving.
• Don’t overrun an exhaust fan. It pulls the air conditioning out of the home.
• Use a programmable thermostat. This allows you to cool your home only when you need it.
• Zone your heating and cooling system. If you spend most of your time in one part of your home or if different people in your home want the temperature at different settings, then zoning can help you be more comfortable and save money on your utility bills.
• Use an attic ventilator. By pulling hot air out of your home, you keep your home cooler in the summer.
• Have your cooling system checked at least once per year by an ACCA member contractor. Your equipment works more efficiently when it is clean and running properly.

• DO NOT turn off your air conditioning unit!
• Set your thermostat at 85 degrees. This keeps the air circulating in your home. High temperatures and humidity can cause damage to your home, your workplace and your health! Humidity can cause wallpaper to peel, floorboards to warp, and most importantly, mold and fungus to form in bathrooms, on furniture and in your air conditioning ducts.
