FREQUENTLY ASKED QUESTIONS
About Boiler Repair
What are common signs my boiler needs repair?
Watch for signs like no heat, strange banging or gurgling noises, leaking water, inconsistent temperatures, or rising energy bills. If your boiler frequently turns on and off (short cycling) or certain rooms stay cold, you likely need service. We can identify the issue quickly and offer reliable repairs.
What’s the difference between a boiler and a furnace?
A boiler heats water and distributes it as hot water or steam through radiators or baseboards, while a furnace heats air and distributes it through ducts. If your home has radiators or baseboard heat, you have a boiler—and we specialize in servicing both traditional and high-efficiency models.
Can you repair both gas and oil boilers?
Yes. Our technicians are trained and licensed to repair both gas and oil-fired boilers. Whether your system is older or a modern condensing boiler, we’re equipped to diagnose and fix it safely and effectively.
Is boiler repair covered by your Care Club maintenance program?
Yes! Our Care Club offers annual boiler inspections, discounted repair rates, priority service, and more. Preventative maintenance can catch issues early and help extend the life of your heating system.
What if my boiler can’t be repaired?
If your boiler is outdated, unsafe, or too costly to fix, we’ll walk you through your replacement options. We install high-efficiency models that save on energy bills and keep your home warm with less waste. We always give honest advice and never push unnecessary replacements.
What are the best materials for boiler repair in modern homes?
Copper or PEX piping, brass circulators, and stainless steel components ensure reliability and energy savings.
How does boiler repair differ for older homes in Connecticut?
Legacy systems may include asbestos insulation, undersized radiators, or gravity-fed piping that complicates repair.
What’s the average cost of boiler repair in Wallingford, CT?
Minor repairs start around $200–$500; more involved jobs with pump or valve replacement may run $1,000 or more.
