Heat Pump FAQ

What is a heat pump?
A heat pump is a highly efficient system that both heats and cools your home. In summer, it moves heat out of your home. In winter, it does the opposite — pulling heat from outside air (even cold air!) and bringing it indoors.

Do heat pumps work in cold climates like Massachusetts?
Yes! Modern cold-climate heat pumps are designed to perform very well in New England winters. They can heat your home even when temperatures drop below freezing.

What is the cost of a heat pump?
Depends! But most heat pump projects we install cost around $14,000 after rebates. At Forge, we apply your rebate upfront, so you don’t have wait 12+ weeks to receive a rebate check.

Can a heat pump replace my current heating and cooling system?
In most cases, yes. A properly sized and installed heat pump system can fully replace oil, gas, or electric baseboard heat, and also replace your window or central AC system.

Do heat pumps lower energy costs?
They can! Because heat pumps move heat rather than generate it, they’re 3–4 times more efficient than traditional fossil-fuel systems. That can mean lower utility bills, especially if you’re switching from oil, propane, or electric resistance heat.

What rebates are available?
In Massachusetts, your project may qualify for Mass Save™ rebates of up to $10,000 for installing a heat pump, plus 0% financing through the Mass Save HEAT Loan.

How long do heat pumps last?
A well-maintained heat pump typically lasts 15–20 years, similar to or longer than a furnace or central AC system.

What’s the difference between ducted and ductless systems?
Ducted heat pumps use hidden ducts like traditional fossil-fuel systems. Ductless heat pumps (“mini-splits”) use sleek wall-mounted indoor units — great for homes without existing ductwork or for adding comfort to specific areas.

Is the installation process disruptive?
Not really! Most installs take just 2–4 days, and a professional team (like Forge!) will walk you through the plan and minimize disruption to your home.
