- Is the condenser (outdoor unit) and furnace (indoor unit) operating? If not, check breakers and fuses; and, verify your thermostat (cooling control) is adjusted to call for cooling and/or working properly also.
- Change your filter regularly. This simple step alone can increase the efficiency of your air conditioner. It will also run less, increasing the life span of your equipment. If ice is forming it is possible that your air filter is severely dirty and restricting your normal air flow.
- As a related issue check your fan blower belt for excessive slack or damage as it can cause low air flow to allow ice to form and thus cause low cooling performance also.
- Wash your condenser coil regularly. Simply turn off your air conditioner, get a garden hose, and spray the coil using an “up/down” pattern. Be particularly attentive if your condenser is close to a dry vent, or if your neighborhood is full of cottonwood trees. These two items are “air conditioner killers”.
If all else fails turn off your air conditioner and call for service. An annual tune up may lower your monthly electrical bill, reduce repair costs and extend the life of the unit.
