ndoor and outdoor AC/Heating coils cleaned on a regular basis (We recommend 2 times a year). Dirt build-up on the indoor coil is the single most common cause of poor efficiency. The outdoor coil must also be checked periodically for dirt build-up and cleaned if necessary.
• Have the refrigerant charge checked. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly.
• Reduce the cooling load by using cost-effective conservation measures. For example, effectively shade east and west windows. When possible, delay heat-generating activities, such as dishwashing or baking, until the evening on hot days.
• Try to not use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder, which in turn increases your utility bill.
• Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. If practical, ventilate at night either naturally or with fans.
