The amount of heat, rated in British Thermal Units (BTUs), that the unit can deliver into the space. Not sure how many BTUs you need? Try our easy Equipment Sizing Estimator.

Seasonal Energy Efficiency Ratio (SEER) is a measure of cooling over an entire season. It is determined by comparing the amount of cooling produced in BTUs in relation to the amount of electricity used. A higher SEER means a system is more energy efficient and would provide comfort at a lower utility cost than a lower SEER system.

A measure of heat pump efficiency while in a heating mode. The higher the number the better the energy efficiency.

Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.

The maximum capacity breaker in the building's circuit panel that can be used on the dedicated electrical line supplying the equipment.

Reciprocating compressors use a piston to compress the refrigerant.

Rotary compressors utilize a roller rotating eccentrically inside a cylinder and a spring mounted blade always rubbing against the roller. As the eccentric rotates towards the blade, the space is decreased and the refrigerant is compressed. Rotary compressors are very efficient.

Scroll compressors consists of 2 scrolls to pressurize refrigerant. Often 1 scroll is fixed and the other orbits eccentrically compressing the gas between the scrolls. Scroll compressors are quiet, smooth and offer highest efficiency ratio of all compressor types.

Scroll Ultratech™ compressors are advanced scroll compressors which offer more features and better diagnostics.

A safety switch, that when/if the pressure in the system gets too low, it will turn off the equipment to avoid damaging it.

The outside diameter of the liquid line pipe (the inside diameter of the connection on the equipment).

The outside diameter of the suction line (the inside diameter of the connection on the equipment).

A TXV is an inline metering device used to regulate the amount of refrigerant entering the evaporator coil. They are frequently used in high efficiency systems.

The noise produced by the unit rated in decibels. 30dbs is equivalent to a whisper, 60dbs is equivalent to a normal conversation, 90 dbs is equivalent to a lawn mower.
