More North Shore Homeowners Choose Heat Pumps to Combat Rising Fossil Fuel Prices

More homeowners on the North Shore City and Suburbs area are choosing North Shore heat pumps to help combat rising fossil fuel prices. These innovative heating systems provide both air conditioning and heating.

In the heating mode, heat pumps pull in the cool air from outside and transfer it into your home to make it warm. In the cooling mode, it works in reverse to remove the hot air from inside your house.

Air Source

Air source heat pumps capture the warmth from the air and transfer it to a home. They run on refrigerant and use a refrigeration cycle to step up the temperature of the air before it is delivered. They are considered environmentally friendly as they don’t burn anything and they use R410A refrigerant which is less damaging to the ozone layer.

They work best in warmer climates, but technology has made tremendous strides and they are now an excellent heating solution for Wakefield homeowners. They operate well even in freezing temperatures. Of course, the homeowner’s energy usage, insulation and draught-proofing all impact how cost-effective they are to operate.

Unlike furnaces and boilers, heat pumps provide a continuous flow of warm air and can also be used to dehumidify your home. They are a great replacement for old, inefficient furnaces and boilers.

Water Source

Water source heat pumps operate on the same principle as air sourced heat pumps but extract heat from a body of water (usually a lake or reservoir). A piping system is laid under the surface and cycles water through the system absorbing and transporting heat to your house.

As with air sourced, the water supply must be of sufficient quality as mineral/biological contaminants can foul the heat pump’s water to refrigerant heat exchanger resulting in a water starvation condition that triggers an automatic shutdown. Kensa can establish the required flow rates during the sizing stage to avoid this scenario.

Open loop systems must be designed to allow for an adequate amount of water flow during load conditions to prevent clogging of the borehole/aquifer. A typical heat pump requires two to three gallons of water per minute for each ton (12,000 Btu/hr) of heating capacity. This is usually achieved by pipeing the heat pumps in parallel using closely spaced header assemblies and dedicated circulators.


An electric heat pump system extracts heat energy from the air, even when it’s cold. In a ducted or ductless mini-split system, a cool liquid in the condensing unit absorbs the heat energy from the outside air and concentrates it.

The heat is then used to warm your home. The electricity that’s used for this is sourced from the electric grid, which means it produces far less carbon than a fossil fuel furnace.

Kearney HVAC is a Mitsubishi Electric Diamond Contractor, and we install their high-efficiency ductless heating systems in homes throughout the North Shore. We also help homeowners get up to $10,000 back with the Mass Save heat pump rebate. To learn more, call us for a virtual home energy checkup. You can also schedule a free, one-on-one consultation with an energy expert to find out what the best heat pump system is for your home. A properly sized heat pump will provide you with optimal comfort while lowering your energy bills.

Heat pumps are one of the most energy efficient options for heating your home. In winter they extract heat from the air outside (even when it is very cold) and pump it into your house. In summer the cycle is reversed and they push heat from your house out into the air, much like an air conditioner.

They rely on electricity but use significantly less of it than furnaces or electric boilers. They also produce no carbon emissions, only extracting heat from the environment.

If you want to improve the comfort of your Winnetka area home and reduce your utility bills, a heat pump is an excellent option. And with the right rebates, you can save up to $13,000 on a new heat pump system!
