Today's air conditioning systems can help keep you from over-heating due to high monthly energy bills.

If your air conditioning system is 10 years old or older, you might be surprised to find out how much more efficient new systems are. In fact, you could experience savings of up to 40%, usually re-paying the cost several times over the life of the equipment.

• Newer air conditioners offer tremendous comfort. The Seasonal Energy Efficiency Rating, (SEER), measures cooling performance, (the higher the rating, the more efficient the unit). Typically, older units have ratings of around 6 SEER, and newer units offer ratings of 13-24.5 SEER. If you have a 6 SEER unit and upgrade to a 13 SEER unit, you could cut your cooling costs in half.

• Air conditioning products feature either a scroll or reciprocating compressor. The type of compressor used will depend on the size and efficiency of the unit.

• Optional variable-speed air handlers are also available to help maximize system efficiency. Whisper-quiet blowers improve air quality by mixing air from floor to ceiling.

Spring System Tune-Up

What you can do to help your air conditioning system run efficiently:

• Follow the manufacturer's maintenance instructions.

• Keep air-supply outlets and return inlets clear of obstruction.

• Clear leaves, brush and dirt (as they accumulate) away from unit.

• If there's a pipe for draining condensate water, check it and keep it clear from blockage.

• Check the air filter once a month (during the operating season). Replace or clean the filter if it looks dirty.

• Invest in a digital thermostat, and program temperatures for your air conditioning system to follow throughout the day.

• Routinely have a professional contractor perform a pre-season check-up. Having your air conditioner inspected and tuned-up can save you money and prevent premature breakdown.

• Schedule your tune-ups early in the spring. You'll have more scheduling flexibility, and be less likely to experience problems during warmer weather.

Here are some of the services your technician will perform during a system check:

• Inspect blower wheels, unit wiring and unit disconnections.

• Check refrigerant charge, motors, and ductwork, as well as, the compressor.

• Clean condenser coils, condensation drain, as well as, clean or replace air filters.

• Lubricate motors and bearings.

Allergies and Your Indoor Air

• Approximately one in five people in America suffer with serious allergy or sinus problems, and over 35 million Americans are affected by seasonal allergies. There's not a lot you can do about pollen and allergens in the air outside, but there's a whole lot you can do for your indoor air.

• Indoor air is often even more polluted than outdoor air. Pollen, dust, smoke from cooking and tobacco, animal dander and hair can collect in stagnant indoor air. Mold, the cause of almost 100% of chronic sinus infections, can infect duct systems.

• Ask your dealer about electronic air cleaners. They do a terrific job of filtering dust, microorganisms and foreign objects. Much more effective than disposable and electrostatic filters, electronic filters can eliminate up to 99% of all household irritants. If you suspect mold, call your dealer to have your ductwork inspected.
