Commercial Boiler Repair & Maintenance

Boiler repair and maintenance is first and foremost a safety issue. Without regular professional maintenance or repair, your boiler system can leak, crack, or wear down, becoming a safety hazard. It may also lose its energy efficiency, costing you a fortune in wasted energy costs. At its worst, a boiler that isn’t properly maintained will face premature replacement, which can be very expensive.

Our boiler system service and repair focus on solving a myriad of common boiler problems:

  • Startup problems
  • Electrical problems
  • High carbon monoxide levels
  • Insufficient heating performance
  • Combustion or ignition problems
  • Radiator, baseboard, or in-floor heating system problems
  • Water or steam leaks
  • And more

Boilers are like any other item that is used frequently. They need regular maintenance to keep running smoothly and as efficiently as possible. From gas boiler services to high-efficiency boiler installation, we do it all to protect the year-round comfort of your home or commercial building.

Commercial Boiler Installation & Replacement

When winters in Cincinnati get cold, having a reliable boiler system is essential to protecting your property and providing comfortable heating to live in. We provide the following boiler services:

  • Removing or replacing the existing boiler, if necessary
  • Selecting an appropriate, energy-efficient boiler system
  • Installing the boiler, plumbing, valves, and related equipment
  • Installing radiators, in-floor systems, and related components

What Our Clients Are Saying

Brandon of National Heating did an excellent job servicing my AC. He is very thorough, knowledgeable, and professional. He discovered that the low outside temperature sensor had not been set up on my Evolution Connex Control and took care of it. I appreciated his top-notch service!

Thomas S.

Great company that I trust. Very thorough. I just had my air conditioner annual service. I used Help in the past. They always tried to upsell every opportunity they had. National Heating and A/C is the real deal from booking the appointment to the actual work. Every person I have dealt with is kind, knowledgeable, and…

Paul M.

I can highly recommend National (previously Nelson Comfort) Heating and Air especially if Sanjay is the company representative. He was beyond good in that he completely cleaned the outside unit and was very thorough with the ac equipment inside the house. He even destroyed a wasp nest that I had not noticed. Five stars for this…

Susan S.

Excellent experience all around. Communication from the company was timely and complete. My service technician Chad Wilson was very knowledgeable, efficient and helpful. I had a lot of questions, having just moved into a house with systems that were unfamiliar to me (geothermal, radiant heat). Chad answered all my questions and spent extra time helping me…

Mary C.

My family has been using this company for years. They've always provided us with honest feedback on pricing for repairs and maintenance. This means a lot to a family on a tight budget. We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
