Can I Fix My Boiler Myself?
While it may be tempting to try and fix your boiler yourself, it is not recommended.
Boilers are complex systems that require trained boiler experts to repair and maintain. Attempting to fix one yourself can not only be dangerous but also cause more damage to your boiler and end up costing you more in the long run. Entrust a reputable boiler repair service in Denver, like ours at Sanders & Johnson, to have your boiler fixed safely.
Could My Boiler Explode?
In extremely rare circumstances, yes, an explosion can occur. Regular preventive maintenance along with an annual inspection, performed by a licensed and experienced professional contractor such as Sanders & Johnson, can help keep your boiler running safely and efficiently.
When should I replace my boiler instead of repairing it?
Boiler repair vs. replacement depends on the extent of repairs and the age of the boiler. For example, for a relatively new boiler with minor issues, repair is the most cost-effective solution. However, if your boiler is nearing the end of its expected lifespan or if you’re experiencing expensive or frequent repairs, it may be time to consider boiler replacement.
How long do boilers last in Denver’s climate?
Most boilers last anywhere from 25-35 years in Denver’s climate. Boiler lifespans vary depending on the make and model, as well as the frequency of servicing. Routine boiler maintenance is one of the best ways to prolong the life of your Denver home boiler.
How can I save money on boiler costs?
If it’s time to replace your boiler, installing an Energy Star boiler is a great way to save on utility costs. These energy-efficient models require less energy to heat your home, resulting in significant long-term savings. We install, repair, and service all boiler models, including Energy Star boilers and Burnham boilers.

Common Boiler Problems We Fix
Not enough heat
Your boiler’s main job is to provide heat, so it’s especially frustrating when it delivers insufficient heat or no heat at all. If your thermostat is set to the correct temperature and your boiler still isn’t heating, chances are it’s due to a more serious internal issue. Our team can diagnose the cause and discuss boiler repair solutions.
Loud noises
When your boiler first turns on, it will usually make a bit of noise before settling down. However, loud or unusual sounds during boiler operation can be a sign of a problem. A professional should investigate any new banging, gurgling, or whistling noises. Common problems like mineral buildup, poor water pressure, and air in the boiler can all lead to unusual sounds.
Leaks
Several issues can cause boiler leaks, including problems with the pressure relief valve and the pump seal. An aging boiler that is starting to corrode can also cause a leak. In most cases, leaks can be repaired. However, if the boiler is nearing the end of its expected lifespan and leaking due to severe corrosion, it may be more cost-effective to consider boiler installation and replacement.
Faulty pilot light
Some boiler models include a pilot light, which must remain on for the boiler to continue operating. This is particularly common in older types of gas boilers. Often, the issue involves access to the gas line, which can cause the pilot light to turn off. Since gas is flammable and dangerous to inhale, it’s best to call a pro if you have any gas or pilot light concerns.
