Frequently Asked Air Conditioning Questions

How often should I change the air filter in my system?

Check it at least every month during peak use, and replace it when it looks dirty enough to significantly impair the air flow through it. Some filters, such as media filters or electronic air cleaners, are washable: others are disposable and must be replaced.

Do I need a Humidifier?

That depends largely on your climate and personal needs. Humidification is definitely helpful in many homes and businesses. Particularly during cold weather, insufficient moisture in the air often is responsible for such assorted problems as stuffy noses, sore throats, even more dust than usual, cracks and dried-out joints in wood furniture, wilted plants and static electricity which jolts hair, clothing and computer disks. Indoor relative humidity may fall to around 7 percent, much drier than even the 25 percent relative humidity of the Sahara Desert! Ideal indoor relative humidity is between 30 to 50 percent.

During summer, should I turn my thermostat up when I leave home?

If your house is going to be empty for more than about four hours, it's a good idea to turn your thermostat up to about 82 degrees or so instead of the 78 usually recommended. Keep the house closed to minimize heat build-up. When you come home, don't set the thermostat any lower than the temperature you actually want-your air conditioning system wouldn't cool any faster and might easily waste money by cooling your home more than needed.
