Boilers heat a huge share of Merrimack Valley homes, and many of them have been running for decades. When yours is leaking, unreliable, or simply past its prime, a new boiler can give you steadier, quieter heat and use less fuel doing it. Caron Heating & Cooling has installed and replaced boilers across Methuen and the Merrimack Valley for 20 years.
We install high-efficiency gas boilers, combi boilers that handle heat and hot water in one unit, and modern oil boilers. Every job starts with an honest look at your current system and a heat loss calculation, so your new boiler is sized for your home, not copied from the old one.

Signs It's Time for a New Boiler
Consider replacement if you’re seeing any of these:
- Your boiler is 20 years old or more
- Leaks, rust, or corrosion on the boiler or near-boiler piping
- Frequent repairs, or a major repair quote
- Rising fuel bills without a change in how you use your heat
- Uneven heat, cold radiators, or rooms that never warm up
- Banging, kettling, or gurgling noises
- Pressure problems or a relief valve that keeps discharging
- Hot water that runs out quickly on a boiler-fed system
We’ll give you an honest repair-or-replace answer. If a repair makes more sense, see boiler repair below.
Boiler Repair or Replacement? Honest Advice
Not every boiler problem means a new boiler. We’ll assess your system, explain what’s wrong, and show you the cost of repairing versus replacing so you can decide. For repairs, see boiler & oil heating repair. If your heat is out right now, see emergency heating repair.
Boilers We Install
We’ll recommend the right type for your home:
- High-efficiency gas boilers (condensing) — more of your fuel turned into heat
- Combi boilers — heat and on-demand hot water from one compact unit
- Oil boilers — modern, reliable oil equipment for homes that stay on oil
- Boilers with indirect water heaters — plenty of hot water from your heating system
- Steam and hot water (hydronic) systems
- Replacement of circulators, expansion tanks, and near-boiler piping as part of the job
Flexible financing is available through Synchrony to help spread the cost of a new boiler. Ask about current options. Financing subject to credit approval.
Our Boiler Installation Process
Free in-home assessment. We look at your current boiler, piping, venting, radiators, and fuel.
Heat loss calculation. We size the new boiler to your home, not to the old unit.
Clear written quote. Equipment options and pricing, with no surprise add-ons.
Professional installation. Removal of the old boiler, new near-boiler piping where needed, startup, and a walkthrough before we leave.
Converting From Oil to Gas?
If gas is available at your street, switching from an oil boiler to a high-efficiency gas boiler is an option worth considering. We handle oil-to-gas boiler conversions, including removal of the old equipment. We also keep oil systems running for homeowners who’d rather stay on oil. We’ll walk you through the trade-offs for your home. Thinking about leaving oil and gas entirely? Ask about a heat pump, which is the equipment that qualifies for the largest Mass Save rebates. Boilers don’t qualify for Mass Save.
Boiler Service & Maintenance
A new boiler lasts longest with a yearly service. Our Comfort Club membership (our Safety & Efficiency Agreement) includes annual boiler service, 20% off repairs, and priority service. See heating maintenance & tune-ups.

Frequently Asked Questions — Boiler Installation
How much does a new boiler cost?
It depends on the boiler type, your home’s heat load, and what your piping and venting need. We give you a free, detailed written quote up front, with financing options if you want them.
How long does boiler installation take?
Many boiler replacements take one to two days. Conversions or major piping changes can take longer, and we’ll give you a timeline before we start.
What is a combi boiler?
A combi boiler provides both home heating and on-demand hot water from one compact unit, so you don’t need a separate water heater tank.
Do new boilers qualify for Mass Save rebates?
No. Mass Save rebates apply to heat pumps and heat pump water heaters, not boilers. If rebates matter to you, ask us whether a heat pump is a fit for your home.
Can you convert my oil boiler to gas?
Yes, if gas service is available at your home. We handle oil-to-gas conversions, including removing the old oil equipment.
