Boiler Installation & Replacement

Considering a switch to boiler heating for your commercial space? Here are some compelling reasons why it might be the right choice for you:

  • Energy efficiency: Boilers are known for their energy efficiency, which can result in cost savings over time.
  • Consistent heat: Boilers provide even and consistent heating, eliminating cold spots and drafts.
  • Longevity: With proper maintenance, boilers can have a longer life span than other heating systems.
  • Quiet operation: Boilers operate quietly, creating a more comfortable and peaceful environment.
  • Improved indoor air quality: Boilers can help your indoor air quality because they radiate heat instead of using ductwork that can get dusty and irritant-filled.

Boiler Maintenance

Regular maintenance is the key to keeping a large commercial boiler running properly and efficiently. At National Heating and Air Conditioning, we recommend at least two service visits a year before and after the heating season. Typical boiler maintenance includes:

  • Cleaning the burners
  • Inspecting the flue and heat exchanger
  • Checking flue gas levels
  • Verifying proper water and air pressure
  • Inspecting the pressure tank
  • Checking the water regulator and pressure relief valves
  • Purging excess air from the system
  • Inspecting water or steam pipes
  • Inspecting the manifold
  • Checking the electrical system
  • Testing thermostat and control systems

Our HVAC professionals will perform all the recommended maintenance for your system according to the manufacturer’s specifications.

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.

We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
