The Best Boiler for Your Budget and Heating Needs: Expertly Installed and 100% Satisfaction Guaranteed

If you need a new or more energy-efficient boiler, we can help you find the right upgrade for your Chicago home. Our boiler technicians are experienced in installing all types and sizes of boilers, that can keep you warm and comfortable while keeping heating bills down.

To run boiler heat, you’ll need pipes routed through your baseboards, radiators, walls, ceilings or floors. If youʼre not set up for this kind of radiant heating system, Althoff Industries’ expert technicians can help you find a solution that is just right for your home, family and budget.

2 Year 100% Satisfaction Guarantee

If you are not 100% satisfied with your new HVAC system in the first 2 years, we will do everything we can to remedy the situation for you. If we can’t, we’ll remove the system we installed and install a brand new system at our expense.

Do I Need a New Boiler

  • Age of Current Boiler - Our experience tells us that life expectancy for cast iron boilers in our area is 20–25 years. While they are relatively new to the industry, manufacturers are telling us that life expectancy for condensing boilers is 15 years.
  • Frequent and/or Expensive Repairs - If your boiler is starting to need repairs on an almost annual basis, it’s near the end of its lifespan. Contrary to furnaces that typically have longer warranties, most boiler repairs are out of warranty after five years. Out of warranty repairs can cost $1,000+.
  • Your Home Isn't Comfortable - Do you have a hard time keeping your home warm?  This could be the sign of an aging boiler or even an incorrectly sized system. Regardless of the cause, you want your home heating system to do its job!
  • Leaks - Water leaking from the boiler can be a sign that it’s time to replace your boiler. In addition to the threat of damaging your property, a leaking boiler can leave you without heat when you need it most.
  • Your Utility Bills Are Too High - As a boiler ages, the wear and tear along with damage caused by lime build up on the heat exchanger will cause your boiler to operate less efficiently. To compensate, your boiler will run much longer to satisfy the same temperature levels. This leads to higher utility bills. Newer models—even cast iron boilers— are more efficient today.
