Frequently Asked Questions
What is the Mass Save HEAT Loan?
It’s a Massachusetts program offering 0% APR financing (up to $25,000, no fees) for qualifying energy-efficient equipment such as heat pumps and heat-pump water heaters, plus weatherization. It requires a free Mass Save Home Energy Assessment first. For eligible projects, it’s almost always the best deal available. See full details →
Can I finance a water filtration system or softener?
Yes. Water treatment is typically financed through the same home-improvement lenders used for HVAC and plumbing — through a personal loan, a home equity option, or point-of-sale contractor financing. We’ll help you compare so you’re not overpaying on interest.
What’s the catch with “no interest if paid in full” offers?
Many promotional plans use deferred interest: if you don’t pay the full balance by the end of the promo window, interest is charged retroactively from the original purchase date. They can be great if you’ll pay it off in time — just go in knowing the deadline. More on contractor financing →
Does checking my options hurt my credit?
Many lenders offer a pre-qualification with only a soft credit check, which doesn’t affect your score. A full application (hard pull) happens only when you move forward. We can point you to soft-check options first.
