Heating & Cooling 101
The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.

Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.

Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.

The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.

Central air conditioning can also be provided through a package unit or a heat pump.

Confortmaker is known for its reliability. Direct Hot Surface Ignition System features an advanced silicon nitride igniter for years of reliable starts. The RPJ® III primary heat exchanger is made of corrosion-resistant weld-free stainless steel. The unique integrated ripple-edged design forces more heat to the outside surface area for higher efficiencies. The two-stage redundant gas valve, two-speed induced draft blower assembly, and variable speed motor operate normally at the lower stage and ramp up as needed. The Variable speed circulation blower motor is pre-lubricated, dynamically balanced, and resilient mounted.
Brand Air Conditioning
The Copeland® features a quieter, lower stage, changing over to the higher stage at higher outdoor temperatures to produce more cool air. A deluxe sound blanket also reduces compressor sound levels. The galvanized steel cabinet features a coated inlet grille with narrower spacing to provide maximum protection as it allows for proper airflow and easy coil cleaning. The Copeland® scroll compressor and the 7 mm copper tubing with aluminum fin coils work collectively to save on energy. The two-speed fan motor operates most of the time on quieter, lower speeds.
