AIR CLEANERS
Air cleaners remove unwanted air-borne materials from the air supply in your home. Depending on the type of device, cleaners can trap particles as small as smoke, pollen and fungal spores and as large as dust, dirt and pet hair. Not only will the air be healthier for you to breathe, but fewer particles circulating in your ductwork will lower the maintenance requirements of your furnace and air conditioning equipment. Less dirt accumulating on exchanger surfaces, fan blades and cooling coils ensures your HVAC system will operate at peak efficiencies for longer periods of time.

HUMIDIFIERS
Proper humidity is another health-related property of the air circulating through your home and is especially important for the very young and elderly. An adequate moisture level will also prevent damaging furniture and woodwork shrinkage. In the latter case, heating costs may be lowered as reduced shrinkage of window and door frames will ensure reduced cold air infiltration. Finally, to most people, moist air feels warmer than dry air so you will be comfortable even at lower, energy-saving temperatures. For best results, a whole-house
humidifier is recommended.

THERMOSTATS and ZONE CONTROLS
Modern thermostats do more than just automatically operate the furnace or air conditioner until a preset temperature is reached. With a
programmable thermostat, you can control the temperature with different set-points for different times of the day and for different days of the week. Your home is comfortably warm (or cool) only when occupied and, therefore, less costly to condition. Energy-saving settings can always be overidden if necessary.
 
Taking precise climate control one step further, you can add
zone controls to your programmable thermostat. By controlling the amount of air flow reaching different parts of your home, you can ensure only frequently occupied areas receive maximum comfort conditioning. By keeping that unoccupied bedroom or basement workshop cooler in the winter, you save on heating costs.

VENTILATORS
Unless they have been retrofitted to control air infiltration, older homes are usually rather drafty. A drafty house is expensive to heat and cool, but does have a higher rate of air turnover. As a result, stale or polluted indoor air is constantly, if slowly, exchanged for fresh, outdoor air.
 
Considerable care is taken when building modern homes to seal them so very little uncontrolled outdoor air gets inside. This greatly improves the energy efficiency of these homes but adds problems of its own as oxygen is used up, yet not replenished, and odours accumulate. In uncommon but worst cases, radon gas can also accumulate. To remedy this situation, a ventilator is recommended.
 
A powered
ventilator forces stale indoor air across the surface of a heat exchanger before it is expelled to the outdoors. An amount of fresh air equal to the air forced out is brought inside and, in the winter, as it passes across the opposite side of the same heat exchanger, it picks up heat from the outgoing air. In the summer, heat is removed from the incoming, outdoor air so energy, used to improve the comfort of your home, is conserved. A ventilator is therefore, an energy-conserving, controlled "draft" device that greatly improves the air quality in a well-sealed home.
