Air Source Heat Pumps

UMR Infinity

Infinity® Variable Speed Heat Pump with Greenspeed™ Intelligence

Air source heat pumps look and are installed outdoors much like regular air conditioners. But unlike an air conditioner, the ASHP will both heat and cool a building.

The outdoor unit is attached to the A-Coil on the furnace inside the house. The ASHP brings the heat from the outside air into the house where it is distributed by the furnace. In the summer, the ASHP reverses and uses the A-Coil on the furnace to absorb the heat from the house so that the unit can dump the heat into the outside air.

The main limitation of the ASHP is the use of external air. As the air cools down towards freezing, there is not much heat left for the heat pump to use. So ASHP’s typically turn off when the outdoor temperature drops down close to 32 degrees F. In the summer the ASHP is trying to move warm air (say 78 degrees F) into the warmer air (say 90 degree F) outside. The outside air has a difficult time absorbing this additional heat so the performance of the heat pump goes down.

Duct Less Air Source Heat Pumps

Carrier Toshiba Duct lessDuctless ASHP are designed for situations where a traditional duct work is not available to deliver heating or cooling to the building.

The ductless unit has three parts, an outdoor unit, indoor unit, and a remote control.

The outdoor unit connects to the indoor unit with a small bundle of cables, including a refrigerant line. The unit is placed outside of your home on ground level. The cables require only a three-inch hole in the wall for installation, eliminating the need for expensive and invasive ductwork.

The indoor unit is mounted on a centrally located wall within your home. Working with your existing heating system, just one ductless system is enough to heat and cool an average-sized northwest home. Keeping your existing heating system in place ensures bedrooms and bathrooms remain at desired temperatures, while the centrally located ductless system keeps your home’s main living areas as warm or cool as you’d like.

Because these systems are duct less, they offer a very cost effective solution for homes that do not have central air conditioning due to lack of duct work. These systems are much more powerful and efficient than the more common place window units.
