Horizontal Flow- A type of furnace, installed on its "side", that draws in air from one side, heats it and sends teh warm air out the other side. Most often used for installations in attics or crawl spaces.
Humidifier- A piece of equipment that adds water vapor to heated air as it moves out of the furnace. This adds necessary moisture to protect your furnishings and reduce static electricity.
Matched System- A heating and cooling system comprised of products that have been certified to perform at promised comfort and efficiency levels when used together, and used according to design and engineering specifications.
Operating Cost- The day-to-day cost of running your home comfort equipment, based on energy use.
Payback Analysis- Overall measure of the efficiency and value of your home comfort system. By combining your purchase price and ongoing operating costs, a payback analysis determines the number of years required before monthly energy savings offset the purchase price.
Reclaiming- Returning used refrigerant to the manufacturer for disposal or reuse.
Reciprocating Compressor- A type of compressor used in air conditioners that compress refrigerant by use a type of "piston" action.
Recycling- Removing, cleaning and reusing refrigerant.
SEER (The Seasonal Energy Efficiency Ratio)- is a measure of the cooling efficiency of your air conditioner or heat pump. The higher the SEER number, the more efficient the system is at converting electricity into cooling power.
Scroll Compressor- A specially designed compressor that works in a circular motion versus an up and down piston action.
Setback Thermostat- A state-of-the-art electronic thermostat with a built-in memory that can be programmed for different temperature settings at different times of the day.
Split System- Refers to an air conditioner or heat pump that has components in two locations. Usually one part of the system is located inside (evaporator coil) and the other is located outside your home (condensor coil).
Thermostat- Unit that monitors and controls your HVAV system products.
Ton- A unit of measure for cooling capacity. One ton=12,000 BTUs per hour.
Upflow- A type of furnace that draws cool air from the bottom and blows the warmed air out of the top into the duct work. This type of furnace is usually installed in a basement or an out-of-the-way closet.
Ventilator- A ventilator captures heating or cooling energy from stale indoor air and transfers it to fresh incoming air.
Zoning- A way to increase your home comfort and energy efficiency by controlling when and where heating and cooling occurs in a home. Programmable thermostats are used to control operating times of the equipment. Dampers are used to direct airflow to certain parts or "zones" of the home.
