The Benefits of New Boiler Installation

Wondering if a boiler system is the right choice for your Cincinnati building? Our experts can help you decide based on your needs, your building, and your budget!

In general, the benefits of boiler installation include:

  • Strong, reliable heating: Boilers heat buildings in a way that’s unique to their operation. Through heated water, boilers provide heat via a series of pipes or radiator systems, which warm your home by radiating a constant, controlled heat. The result is heating without any of the cold spots of a furnace system, as well as a heat that remains constant no matter what nature throws your way.
  • Easy maintenance: With the exception of annual boiler maintenance service, these systems generally require very little in the way of care or ongoing upkeep.
  • Additional functionality: Boilers can heat your building and water. This gives a boiler the dual function of a heating system and a water heater. In fact, while boilers can serve as an auxiliary water heater, they can also act as a primary water heater if set up correctly.
  • Minimal dust: Without a duct system and forced air, boilers won’t move as much dust and debris through your space. That can mean cleaner air and less dust creating problems in your system. It can also mean you don’t have to work about checking or replacing air filters!
  • Quiet operation: Unlike furnaces that create a constant drone, boilers operate at near silence, barely making a whisper. That can make your space more peaceful and relaxing, as well as keep it cozy!

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.…
