What could cause a boiler not to heat properly?

If your boiler struggles to heat your home, it may have an ignition issue, a thermostat malfunction, or a problem with its internal components. Sometimes the issue involves the circuit board or a communication failure between parts. A professional inspection is the fastest way to determine what is causing your system to fail. For fast, dependable solutions, contact Aire Serv of Central Illinois.

What could cause a boiler to leak?

Worn seals, loose fittings, cracks, or shifts in system pressure can cause a leaking boiler. Even a small leak can lead to bigger issues, including water damage or system failure. It is important to inspect the leak quickly to prevent further problems. Professional diagnosis helps ensure the right repair is made without guesswork. If you notice any signs of leakage, protect your home and contact Aire Serv of Central Illinois to Schedule Service .

How much greater does a new system function?

Newer boilers have higher AFUE ratings than older models, which means they convert more of the fuel directly into heat. Older systems often run at just 56% to 70% efficiency, leading to wasted energy and higher bills. Modern high-efficiency boilers can reach 90% AFUE or higher, offering improved comfort and consistent heating. Upgrading can reduce energy waste while creating a more comfortable home environment. To learn more about how much efficiency you can gain, Schedule Service today.

How much does it cost to replace a boiler?

The cost of replacing a boiler varies based on fuel type, size, efficiency level, and installation requirements. On average, a replacement costs between $3,000 and $8,000. Replacing your boiler with the same fuel type is typically more affordable, while switching to another fuel source or choosing a high-efficiency model can increase the price. If you’re ready for a clear, upfront quote, contact Aire Serv of Central Illinois and Schedule Service .

How often should boilers be professionally maintained?

Most boilers should receive professional maintenance at least once a year to make sure the system is operating at peak performance. Yearly checkups can help catch small problems before they turn into an expensive repair. With routine servicing, this can also improve efficiency and extend your system's lifespan. Regular maintenance also makes sure that your boiler is ready for the coldest seasons. To keep your system running smoothly, schedule service with Aire Serv of Central Illinois.

What could cause a boiler to lose pressure?

Pressure loss in a boiler can be caused by leaks, faulty valves, air in the system, or an issue with the expansion vessel. When the pressure level drops too low, your boiler will not be able to heat your home effectively. This may seem like a small issue, but it will need professional troubleshooting to help prevent long-term damage. If you ignore the problem, it can cause the system to shut down or require additional repairs. If you are noticing fluctuating pressure, schedule service to make sure your boiler is operating properly.

Is it normal for a boiler to turn off and on frequently?

A boiler turning off and on frequently is called short cycling, which thermostat issues, blocked pipes, or improper system sizing. Short cycling can cause lower efficiency and can shorten the boiler’s lifespan. Frequent cycling will also waste energy and can cause inconsistent heat in your home. Schedule Service with Aire Serv of Central Illinois and have a professionals diagnose the root cause and help restore your boiler to proper function.
