What is the rated heating capacity of the unit installed?

Air Source Units - SEER (Seasonal Energy Efficiency Ratio) - The total cooling of a central unitary air conditioner or unitary heat pump in BTU's during its normal annual usage period for cooling by the total electric energy input in watt-hours during the same period.

Geothermal Units - EER (Energy Efficiency Ration) - A ratio calculated by dividing the cooling capacity in BTU's per hour (Btuh) by the power input in watts at any given set of rating conditions, expressed in Btuh per watt (Btuh/watt).

EER and SEER can not be compared equally. Air source equipment is rated by SEER and geothermal equipment is rated by EER. EER changes with the inside and outside conditions, falling as the temperature difference between inside and outside gets greater.

Geothermal Units - COP (Coefficient of Performance) - compares the heating capacity of a geothermal heat pump to the amount of electricity required to operate the heat pump in the heating mode.

Air Source Only - HSPF (Heating Seasonal Performance Factor) - is specifically used to measure the efficiency of air source heat pumps. The efficiency of air conditioners are often rated by the HSPF as defined by the Air Conditioning, Heating.

The higher the HSPF rating of a unit, the more energy efficient it is. HSPF is a ratio of BTU heat output over the heating season to watt-hours of electricity used. It has units of BTU/watt-hr.

Depending on the system, an HSPF ≥ 8 can be considered high efficiency and worthy of a US Energy Tax Credit.

The HSPF is related to the non-dimensional Coefficient of Performance for a heat pump, which measures the ratio of heat energy delivered to electrical energy supplied, independently of the units used to measure energy. The HSPF can be converted to a seasonally-averaged COP by converting both the BTU heat output and the electrical input to a common energy unit (e.g. joules). Since 1 BTU = 1055 J, and 1 watt-hour = 3600 J, the seasonally-averaged COP is given by:

Avg COP = Heat transferred / electrical energy supplied = HSPF * 1055 J/BTU / 3600 J/watt-hour = 0.293 HSPF.

Thus, a system which delivers an HSPF of 7.7 will transfer 2.25 times as much heat as electricity consumed over a season.

What type of warranty came with the unit installed?
Variable or Two-speed
Desuperheater?
A desuperheater is a small, auxiliary heat exchanger that uses superheated gases from the heat pump's compressor to heat water. This hot water then circulates through a pipe to the home's storage water heater tank.
What type of back up heat are you using if any?
kW
This only needs to be filled out for Electric Heat Back Up ONLY.
What type of loop does your geothermal unit use?
Name of the local HVAC dealer / contractor who installed your unit.
Please list the phone number for the dealer / contract who installed your unit. This will speed up the verification process.
