How Often Should I Change My Air Filters?

Inspect each month and change or clean filters as needed. Time intervals frequently vary with each family. The most important aspect of efficient operation of your heating and cooling system is proper air flow. Dirty air filters will severely limit air flow, which can cause the compressor to run continuously or overheat your heat exchanger. Dirty filters could cause a 20 percent or more increase in operating costs. The outdoor units should be free of debris to ensure uninterrupted movement of air. Check out these Filter Tips and our Guide for Indoor Air Quality.

What Type of Heat Pump is Best?

One that is installed by Howell's of course! No, seriously, the efficiency of the heat pump when used as an air conditioner is known as the Seasonal Energy Efficiency Ratio (SEER). In January of 2006 the Department of Energy enforced the increase to a 13 SEER minimum standard for all heat pump and air conditioner production. A fair method of comparing the heat pump to other heating systems is to use the Heating Seasonal Performance Factor (HSPF). The HSPF compares relative equipment efficiencies. A HSPF of 6.8 or higher is recommended.

Pesticides

PESTICIDES

Sources: Products used to kill household pests (insecticides, termiticides, and disinfectants). Also, products used on lawns and gardens that drift or are tracked inside the house.

Health Effects: Irritation to eye, nose, and throat; damage to central nervous system and kidney; increased risk of cancer.

Levels in Homes: Preliminary research shows widespread presence of pesticide residues in homes.

Steps to Reduce Exposure:

• Use strictly according to manufacturer's directions.

• Mix or dilute outdoors.

• Apply only in recommended quantities.

• Increase ventilation when using indoors. Take plants or pets outdoors when applying pesticides to them.

• Use nonchemical methods of pest control where possible.

• If you use a pest control company, select it carefully.

• Do not store unneeded pesticides inside home; dispose of unwanted containers safely.

• Store clothes with moth repellents in separately ventilated areas, if possible.

• Keep indoor spaces clean, dry, and well ventilated to avoid pest and odor problems.
