Boiler Replacement FAQs
How do I know if I need a new boiler?
If your boiler is more than 15 years old, needs frequent repairs, or struggles to heat your home evenly, it’s probably time to consider a replacement.
What type of boilers do you recommend?
Weil-McLain is our most common recommendation because it offers dependable performance, great efficiency, and easy maintenance at a great value. We can install boilers from any manufacturer if you have one in mind.
What do you recommend for maintenance?
It’s critical that your boiler has a routine service from a professional at least once a year, preferably before the winter. Regular service helps your boiler last longer and run more efficiently.
My heat is out, how fast can you replace my boiler?
We offer 24/7 service if your boiler breaks down. Most installs are completed in under 1 day. Depending on the time of day, if we can’t get your new boiler immediately, we’ll do our best to get your heat back on.
What types of boilers do you work on?
We install both standard and high-efficiency gas boilers for baseboard and radiator systems. We do not work on oil systems.
How much is a boiler near Greenwich?
How much a boiler costs depends on the brand you select, the size of your home, and whether it’s a standard or high-efficiency boiler.
How long will my new boiler last?
With proper installation and annual maintenance, most gas boilers last 15–25 years. Rugged boilers like cast iron can last longer. To get the most out of your boiler, make sure it’s serviced at least once a year.
Can you handle my boiler service after install?
Yes, and we recommend it. Having one technician who knows your system helps prevent issues, improves efficiency, and extends the life of your boiler.
