Boiler repair

Our repair technicians respond quickly to diagnose and fix boiler problems, restoring heat and hot water to your property as soon as possible. We arrive equipped with commonly needed parts and tools to complete most boiler repairs and services on the first visit, minimizing your home’s downtime and discomfort. 

We look for the immediate problem and find the root cause to guarantee your boiler will continue working after we leave. From faulty thermostats to zone valve issues, we’ve seen and repaired them all. 

Boiler maintenance

Preventive maintenance is the number one way to guarantee your boiler will work during the dead of winter. We recommend scheduling a maintenance tune-up annually, in the fall before the busy winter season. Our boiler maintenance in Denver includes: 

• Checking all pressure gauges for correct settings.
• Cleaning all dust and residue on the heat exchanger.
• Determining if all combustion parts are working properly.
• Tightening any loose components. 
• Running safety and efficiency diagnostic checks.  

Denver’s water quality and altitude can affect boiler performance in unique ways. Our maintenance service accounts for these local factors, addressing issues like mineral deposits and combustion efficiency at high elevations. We recommend annual maintenance before the heating season begins, giving you confidence that your boiler is ready to handle whatever winter brings

Not servicing your boiler annually can result in higher energy bills, reduced efficiency, and costly breakdowns during peak demand. Scheduling preventive maintenance is also the best way to extend your unit’s lifespan.

Boiler replacement & installation

Well-maintained boilers last between 25 and 35 years, and when the repair costs start becoming frequent for your older boiler, it may make more sense to replace it with a newer and more efficient model. Newer models come with higher AFUE (Annual Fuel Utilization Efficiency) rate, meaning they convert more of their fuel into heat.

High efficiency boilers range from 90 to 98% AFUE and usually have a secondary heat exchanger for extra efficiency.

Our team helps you select the right boiler for your property, considering factors like square footage, insulation levels, hot water needs, and your budget. We work with leading manufacturers such as Lochinvar, Weil-McLain, Burnham, and Laars to offer options ranging from electric to gas boilers.

Our installation estimates include all costs upfront, with no hidden fees or surprise charges. We also help you explore available rebates and incentives from local utilities and government programs that can offset your investment in a new, more efficient boiler system.

Common Boiler Heating System Problems We Repair

As a boiler heating system repair company in Denver, CO, there are common issues we see when out on the job. Recognizing these common boiler heating problems will help homeowners understand when they need boiler repairs.

• Faulty thermostats 
• Stuck zone valves
• Leaking pipes
• Corroded tanks
• Sediment mineral buildup in the tank
• Pilot light issues
• Heat exchanger issues

Another issue that is less common comes from carbon monoxide alarms. Incomplete fuel combustion or a cracked heat exchanger can cause a carbon monoxide leak. Carbon monoxide concerns are taken extremely seriously by Sanders & Johnson. If we detect any safety issues during our service, we address them immediately to protect you from this dangerous gas.

Our technicians work with all major boiler types and fuel sources. We service natural gas boilers, which are the most common in Denver, as well as electric and propane systems. 

We work on all major boiler brands, but we always recommend Burnham Boilers and Laars. Burnham Boilers are often considered the latest and greatest in residential boiler technology. They are highly efficient and quiet. Laars is another great brand, using the latest in fuel flow and heating technology.
