What is an ‘Air Source’ heat pump?
An air sourced heat pump uses a compressor and refrigerant to extract heat from the outside air and bring it in to heat the home. This type of system uses a fraction of the power that an electric furnace would need to heat a home because most of the heat coming from the outside air. Air sourced heat pumps are also able to cool and provide air conditioning in the summer.
Westisle is able to offer a full range of heat pump options with efficiency and cost to suit most budgets. This includes new variable speed or VRF models from Trane and Mitsubishi. These systems offer exception performance in cold weather and are among the quietest systems available.
If we presently have either an oil, gas or electric furnace. Can we add a heat pump to it?
Yes, many Westisle customers have added a heat pump to their existing oil, gas or electric furnace to cut heating expenses. You would then use your oil, gas or electric furnace as back-up heat, which in this climate, would be very infrequent. You could expect your oil bills to drop substantially.
Will a heat pump heat the whole house all the time?
If you have hooked up a heat pump to an existing ducted forced air system the heat pump will provide both heating in winter and cooling and dehumidifying in summer. However, when the outside temperature goes below 4 degrees Celsius the auxiliary heating system might kick in to supply the added heat needed to keep the house at your desired temperature.
In summer can I get central air conditioning throughout the house?
Yes, one of the nice benefits of owning a heat pump is; not only do you get economical heating, but with the flick of a switch you can enjoy cooling throughout the house in summer.
How do I know what size of heat pump I need and where to situate the outside condensing unit?
A Westisle customer service representative will be happy to come out to your home and do a complete heat loss analysis to determine the size and location of your new heat pump.
What gets hooked up to my existing furnace when I add a heat pump?
Should you decide to go ahead with a adding a heat pump to your furnace the following items will be added.
An example of a split heat pump application (an indoor air handler and an outdoor unit).
A disconnect electrical switch will be placed close to the outdoor condensing unit. Two small diameter copper pipes (one suction line and one vapor line) will be extended from the condensing unit and run into your furnace. These lines will be installed with great care as to look as pleasing as possible.
In the furnace area the pipes will be hooked up to an ‘A’ coil inside the plenum of your furnace.
If needed, we will install a new thermostat to control your new heat pump investment. Westisle can also offer you a full seven- day program capability thermostat as well.
How do I know if my present electrical service is adequate?
A Government Certified Electrician should do an inspection to make sure you have adequate power to run the new heat pump. If your present system is sufficient, then in most cases an additional line voltage wire will have to be run from the fuse box out to the new shut-off box located outside beside the condensing unit. If it is determined that your present amperage is not sufficient then the Government Certified Electrician will give you a quote on upgrading your present electrical box.

Yes, you could replace your old furnace with an air handler and optional electric heat (as per below). In most cases the new air handler will be smaller than your existing “old” oil furnace. The electric back up heat would only come on occasionally.
What is SEER, TONNAGE AND AFUE?
SEER: The seasonal energy-efficiency ratio (SEER) rates how many Btu an air-conditioning unit will remove for each watt of electricity consumed. The higher the SEER, the less you spend on operating costs. Federal law mandates a minimum SEER of 13 for all new air-conditioning units.
TONNAGE: An air-conditioning ton equals 12,000 Btu per hour. That means a three-ton air conditioner can remove about 36,000 Btu of heat per hour from your home.
AFUE: The annual fuel-utilization efficiency estimates how much heat a unit delivers for every dollar spent on fuel. The higher the AFUE, the lower your heating bills.
