New Boilers for Homes That Need Reliable Heat
Boiler installation and replacement services for residential customers in Boulder, Colorado.
If your boiler in Boulder has broken down repeatedly, requires frequent repairs, or no longer heats your home evenly, replacement may be more practical than another repair bill. Older boilers lose efficiency over time, and parts for discontinued models can be hard to find. A new boiler restores consistent heat, lowers energy costs, and eliminates the worry of unexpected breakdowns during cold weather.
DNI Heating and Air installs and replaces boilers for residential customers in Boulder. They work with brands including Allied, American Standard, Burnham, Lennox, Lochinvar, Rinnai, Weil McLain, and many others. Whether you need a new boiler for a home that never had one or you are replacing an outdated or broken system, they will help you select the right model and handle the full installation.
If your current boiler is showing signs of age or has stopped working, reach out to DNI Heating and Air to discuss replacement options for your Boulder home.
What Installation Involves and What You Will Notice After
The installation process in Boulder begins with removing your old boiler if you are replacing an existing system. The crew disconnects the old unit, removes it, and prepares the space for the new boiler. They install the new system, connect it to your home's water lines and heating zones, and test all components to ensure proper operation. Depending on the layout of your home, this may take one to two days.
Once the new boiler is running, you will notice more even heat throughout your home, quieter operation, and lower energy bills compared to your old system. The new unit will also require fewer repairs and provide more reliable performance during cold stretches.
The installation includes connecting the boiler to your existing radiators, baseboard heaters, or radiant floor system, but it does not include upgrades to those components unless discussed in advance. If your heating zones need adjustments or your thermostat needs replacing, those can be addressed during the same visit.
