Signs Your Boiler Needs Repair
Boilers run quietly for years, then fail on the coldest night of the month. These are the problems we see most:- No heat or no hot water. The boiler won’t fire, or it runs and the house stays cold.
- Radiators or baseboards that are cold or heat unevenly. Often trapped air, a failing circulator pump, or a zone valve problem.
- Banging, kettling, or gurgling noises. Usually air in the system or scale buildup.
- Water leaking from the boiler, the pipes, or the relief valve.
- Pressure that’s too high or too low on the gauge.
- The boiler shuts off on its own or won’t stay lit.
- Higher heating bills with no change in how you use the house.
What to Check Before You Call
- Check the thermostat. Make sure it’s set to heat, set above the room temperature, and has fresh batteries if it uses them.
- Check the power. Look for a tripped breaker and make sure the boiler’s service switch is on.
- Look at the pressure gauge. If it’s well outside the normal range, don’t try to fix it yourself. Tell us what it reads when you call.
- If you see water leaking, shut off the water feeding the boiler if you can do it safely, and call us.
- Call (203) 894-2533 and tell us the make of the boiler if you know it.
Our Boiler Repair Service
We start by finding the actual cause, not swapping parts and hoping. Then we tell you what we found, what it costs to fix, and whether a repair makes sense, before any work begins. Typical boiler repairs include:- Ignition and burner problems
- Circulator pump and zone valve replacement
- Thermostat and control issues
- Leaks, relief valve, and expansion tank problems
- Bleeding air from the system and restoring even heat
Annual Boiler Service and Tune-Ups
Connecticut winters are long, and a boiler that gets checked once a year in the fall is far less likely to quit in January. During a service visit we:- Inspect the burner and ignition
- Check system pressure and the expansion tank
- Test safety controls
- Inspect the venting and flue
- Check the circulator pumps and zone valves
- Look for leaks, corrosion, and wear
- Test the thermostat and controls
Boiler Repair or Replacement?
Many boilers last 15 to 30 years, depending on the type and how well they’ve been maintained. If yours is older, needs repeated repairs, or is leaking from the boiler itself, we’ll go over the repair cost against replacement and give you our honest recommendation. Financing is available if replacement makes more sense.Boilers We Service
We work on the boiler you already have, so you don’t need to replace a system that can be repaired. That includes the parts around it: circulator pumps, zone valves, thermostats, expansion tanks, and the piping and radiators or baseboards that carry the heat through your home. If your system includes an indirect water heater tied to the boiler, we can look at that too. When a replacement makes more sense, we help you choose a boiler sized for your house.Boiler Repair FAQs
Do you repair boilers in Danbury?
Yes. Call (203) 894-2533 and tell us what’s going on. We’ll get a plumber scheduled to take a look.
Why is my boiler not heating my house?
Common causes are a thermostat or power problem, a failed circulator pump or zone valve, trapped air, low pressure, or an ignition problem. We diagnose it on site and explain your options.
How often should a boiler be serviced?
Once a year, ideally in the fall before the heating season starts.
What does a boiler service visit include?
We check the burner and ignition, pressure, safety controls, venting, pumps, and controls, and look for leaks and wear. We tell you what we find.
How long does a boiler last?
Many last 15 to 30 years depending on the type and maintenance. If yours is getting old and repairs are adding up, we’ll help you compare repair and replacement.
Is it worth repairing an old boiler?
Sometimes. A single part failure on a boiler that’s otherwise in good shape is usually worth repairing. A leak from the boiler itself, or repeated breakdowns, usually points toward replacement.
Can you fix a boiler in an emergency?
Call us right away if you have no heat in freezing weather or a boiler leaking water. See our emergency plumbing page for what to do while you wait.
