Repair vs. Replacement When to Consider a New Heating System
If your furnace, boiler, or heat pump is 15 to 20 years old or older, it may be approaching the end of its useful life, especially if you are seeing rising energy bills, frequent breakdowns, or uneven heating throughout your home. In some cases a repair still makes sense. In other cases replacement is the better long term decision. We look at the full picture, including age, repair history, fuel efficiency, available rebates from Mass Save, and how well the current system fits your home. When repair costs start to climb past 30 to 40 percent of the price of a new system, or when safety concerns appear like cracked heat exchangers or carbon monoxide leaks, replacement becomes the smarter move. We install high efficiency furnaces, boilers, and heat pumps from trusted manufacturers like Trane, Carrier, Mitsubishi, and Navien, and we offer clear Good, Better, Best options so you can choose what works for your home and budget. We also handle Mass Save rebate paperwork in house so you keep more of your savings up front.
