# 1 Dirty AIR FILTERS Change or clean your filters as needed for your type of filter. Dirty filters restrict the airflow, making it hard to let your air
conditioner circulate air.

# 2 lack of
maintenance. GET YOUR SYSTEMS CHECKED BY A LICENSED ESTABLISHED COMPANY. That has certified technicians that can check Freon
levels and several other suggested Items.

How can I make my air conditioning system more efficient?
Have the coil cleaned and rinsed on a regular schedule, and make sure your clothes dryer is vented more than ten feet from your air conditioning –
heat pump -outdoor unit. Lint from the dryer will be sucked into the condensing coils and lower the system’s efficiency. You can rinse off the outdoor
coils in between maintenance visits, but be sure to use a soft spray that won’t damage the coils, and make sure you turn off the power to the

Have your Duct system checked at least once a year for leaks and damage. A leaky or damaged duct system can cost, on average, as much as 40 %
of your heating and air conditioning bill. Ducts can be sealed with spray adhesive, mastic, and tapes. These repairs pay for themselves.

Have your insulation level checked (these levels decrease do to activity of workers, humidity, animals, leaky ducts, and settling).

Do not block registers. This includes keeping furniture and drapes away from them.  Make sure your outdoor fin coils are not bent blocking airflow.
This can cause your system to overheat and cause damage.

Clear away any obstructions and debris from around your outside unit. This includes pruning overgrown plants and bushes. There should be several
feet of space around the unit in order for it to effectively draw air into the outdoor coil.

Shade your outdoor air conditioner unit. According to the U.S. Department of Energy, a properly shaded unit is up to ten percent more efficient then
one that is not shaded.

Have your
ductwork professionally cleaned every few years. Obstructions in the ducts are almost as bad as leaks when it comes to reducing

What is a good temperature difference? On average, between 15-20 degrees. You can check this using an accurate thermometer to measure the
temperature coming out of the supply duct minus the air temperature going into the return air or filter. The system should be running for 10-15
minutes, and the outside temperature should be above 80 degrees.

Raise your temperature settings, when you plan to be away for several hours.  Keep the systems indoor fan on auto. Use ceiling fans to keep air
moving and to circulate the air throughout your home or office.

Check that your

Use blinds or drapes to shade any south or west facing windows during the hottest parts of the day. If you don’t want to cover these windows,
consider solar film.  Turn off lights that are not needed, and change out old light bulbs with LED bulbs. These LED bulbs use less power, last many
years longer, and do not produce heat like incandescent bulbs.  Do not use heat producing appliances like your oven, dishwasher, or dryer until late
evening. And make sure you have your dryer vent cleaned on a regular schedule to prevent longer run time and prevent fires.   Check your home or
business for any unwanted air leaks. Check windows, doors, wiring and plumbing.

Why do my lights dim when my ac or heat pump starts?
Air conditioning systems-heat pumps, refrigerators, freezers, furnaces and other devices that have large motors require large amounts of power
when the motors first starts. Once the motor is running, the energy requirements drop. AC – heat pump units come equipped with start-up
capacitors. These give the motor a boost of power when the unit starts up. But over time, these capacitors can get weak and become ineffective.
Eventually the power draw can cause circuit breakers protecting the wiring of the unit to trip. Your system may be overcharged with refrigerant.
Overcharging puts stress on your compressor, making the system start hard. Excessive dimming can also be caused by a loose neutral wire in the
breaker panel.
