A boiler system keeps a home warm and provides hot water. It requires regular maintenance, and homeowners must understand boiler repairs and services.

Strange noises from a boiler are a sign that something is wrong. A pro can diagnose the problem and fix it.

Thermostat Repair

While a well-maintained boiler can last up to 15 years, it’s common for the unit to require maintenance or repair. Whether the thermostat needs to be cleaned, the batteries replaced, or other necessary repairs, the team of professional technicians at One Hour Heating & Air Conditioning is ready to help!

The thermostat regulates coolant flow to prevent the engine from overheating. It starts closed to warm up the motor, then gradually opens as the coolant reaches the right temperature. When the thermostat malfunctions, it can cause the engine to overheat and damage the radiator and other vital components.

While overheating is the most obvious sign that a thermostat is terrible, there are also other warning signs, such as a low reading on your temperature gauge or a check engine light indicating an issue with the cooling system. Keeping an eye on these signs can help you avoid expensive overheating repairs later down the line.

Boiler Repair

If your boiler is making strange sounds, it’s time to schedule a service appointment. Odd noises, such as popping or rumbling, may indicate that the system is experiencing limescale buildup, trapped air, or an issue with the heat exchanger.

Leaks are another common reason to contact a boiler repair company. This could be due to a broken thermostat, faulty valves, or a malfunctioning circulator pump. A leaky boiler can lead to costly water damage throughout your home if left unattended.

Carbon monoxide leaks can also be dangerous. Leaking boilers should be repaired immediately by a professional to prevent further damage and reduce the risk of CO exposure in your home.

Water Heater Repair

A boiler system rapidly heats water delivered through copper or plastic (PEX) pipes to radiators throughout a home for warmth. Popular high-efficiency models can cut energy costs by up to 30%.

Boilers can develop issues ranging from minor to major, depending on how well they’re maintained. For example, a leak could require more fuel to keep pressure up, or corrosion and buildup might make the unit inefficient.

Keeping up with regular maintenance service helps your boiler last longer, which cuts repair costs and lowers your utility bills. A pro will inspect and clean your boiler, check that the pilot light is on and burning blue, and take a carbon monoxide reading. Some services will also include checking the anode rod — a metal probe that collects corrosive elements inside the tank. This should be replaced every three years to keep the boiler rust-free. A new anode rod costs about $20 to $50.

Plumbing Repair

Having boiler issues at inconvenient times can feel catastrophic, but they are typically easy to fix when a professional technician is called to address the problem. Leaving these problems unresolved can lead to more extensive and expensive repairs or even the need to replace an entire system. That’s why calling a service company at the first sign of trouble is essential.

A leak, zero heat, or odd noises are signs that it’s time for a home boiler repair. A faulty expansion tank, frozen condensate lines, or worn-out seals often cause leaks. Odd noises can be caused by a mineral deposit buildup that requires descaling.

A routine maintenance schedule can help avoid these issues and save energy that an inefficient boiler system would otherwise waste. A comprehensive maintenance plan can include tasks such as:
