DIY Air Conditioning tips

Clean around outdoor condenser unit. Your outdoor unit will work most efficiently if it is clean and clear of debris. A more thorough, in-depth cleaning should be performed by a professional.

Vacuum indoor vents and keep vents unblocked. You can vacuum dust and any debris away from indoor supply vents to help maintain steady airflow from your system. Also, keep items like blinds, furniture and toys away from blocking the vents.

Increase your thermostat by a few degrees. Typically, adjusting temperatures 5 – 8 degrees (down in winter, up in summer) can help save money and energy. With a programmable thermostat, you can automatically adjust the temperature for different times of the day or during times you are going to be away from home for several hours.

Keep lamps and other heat producing appliances away from your thermostat. Having heat producing appliances near your thermostat will tell it that the air in your home needs to be cooled more, causing the system to run longer and work harder than it may need to.

Keep curtains and blinds closed in the heat of the day. When direct sun hits the windows in your home, keeping your curtains or blinds closed can keep some of the heat from warming the inside of your home.

Clear your drain line. There is a drain by the indoor cooling coil, typically mounted above the furnace in the basement. If you flush one cup of chlorine bleach down your air conditioning drain and rinse it with a gallon of water, you can keep your drain clear through the summer. Keeping your drain line clear can save your basement from taking on water if the drain becomes blocked.

Avoid using your dryer and oven in the hottest hours of the day. Running your dryer will cause warm air to be drawn into your home and using your oven will add additional warm air to your home, causing your air conditioner to have to work harder.

Insulate any exposed ductwork. Make sure ductwork that runs through an unconditioned space is properly sealed so it doesn’t leak any of your conditioned air. You can fix visual leaks with a specialized duct-sealing tape that is UL 181-rated, but be sure a professional also checks the ductwork during your next scheduled maintenance visit. It’s also recommend that your ductwork be insulated using the proper thickness duct insulating material.
