Boiler Replacement Services in Denver, CO

Your boiler is one of the most important appliances in your home. You rely on it to keep your house warm and safe. Residents in Denver, CO, and the surrounding area know firsthand how cold our winters get, and it’s important to ensure that your boiler is in prime working order.

While some boiler issues can be repaired, if you are experiencing frequent problems, you should consider a full replacement. Residential boiler replacements can be a fast process and will leave you with a modern system that is more energy-efficient and easier to maintain.

So how do you know when it is time to replace your boiler? Here are a few signs to look out for that indicate it may be time for a replacement:

Old Age

One of the number one reasons for residential boiler replacements is because the boiler has reached the end of its lifespan. You may want to believe that your boiler can last forever and that any issues can be solved with repairs. Unfortunately, that is not the case.

Boilers generally last between 15 and 25 years. The range is rather large because there are lots of factors that determine the lifespan, including usage and how well it is maintained. If your boiler is in this age range and you find that you are continually calling for repairs, it is time to consider a replacement.

Unusual Noises

Boilers will always make a certain amount of noise; they are not silent machines. However, the noise level should be reasonable. If you notice that your boiler is exceptionally loud, that may be an indication that the system needs to be replaced.

In addition to the noise level, there are certain sounds that a well-functioning boiler should not make. For example, any clanking noises or loud bangs indicate that something is wrong.

You’ve probably owned your boiler for years, so you know what it normally sounds like. Don’t ignore abnormal sounds. If you detect a change and the noise becomes a distraction, it is time to consider a replacement.


Boiler leaks are a sign of serious boiler trouble. The moment you notice a leak, you should contact a professional. Even small leaks that are left untreated can cause huge issues down the road. Leaks have a tendency to get worse and need to be addressed promptly.

Old boilers are more prone to leaks simply because they have worn down over the years. Replacing your boiler can be a great thing to do to protect your house from property damage due to boiler leaks.


Corrosion is an obvious sign that your boiler has seen better days. While most systems are designed to resist corrosion, broken valves and leaks do happen, which can accelerate the buildup of rust.

Sometimes these issues can be fixed by repairs, but if you have an older system, corrosion likely means that the system is simply worn out. In this case, it is best to consider a boiler replacement.


Your boiler should work predictably and shouldn’t cause swings in your energy bill. If you notice that your boiler is having trouble heating up or it takes a long time to heat your home, it may be time for you to look into boiler replacements.

Inefficient boilers use more energy and will result in an increase in your energy bill. In addition, if your boiler is not running efficiently, that means it is working harder and will wear out faster than it normally would.

Replacing your boiler will ensure that your system is running efficiently, even more efficiently than the best case with your old system. Newer systems are simply more sophisticated and work smarter.

Bad Smells

A properly operating boiler should not give off any odor. If you notice smells coming from the boiler, it may be time to consider a replacement. Smells are almost always indicative of an underlying issue. For example, rust and dirt deposits can damage your boiler and will also cause an odor.

An odor does not have to be strong to indicate that something is wrong. Even if you only notice a smell some of the time, or it is faint, it is better to look into boiler replacements sooner rather than later.

Needing Frequent Repairs

One tell-tale sign that you need a boiler replacement is a constant need for repairs. A repair here and there is relatively normal, especially for boilers that are heavily used. However, the continual need for repairs means that there is a persistent underlying issue in the system itself.

Eventually, it doesn’t make sense to keep repairing your boiler. Repairs can become more expensive, and older systems tend to be less receptive to constant maintenance. If you are constantly calling for repairs, it is time to consider looking at boiler replacements.
