Signs You Need Boiler Repair Services

Your problems might be as obvious as a total breakdown, but sometimes boiler issues can be a little more vague. Contact our team for professional repair if:

  • You’re noticing higher heating costs: Modern boiler systems are quite efficient, and as such you can generally expect fairly normalized heating bills throughout the season. Noting a spike in your energy costs? There’s probably an issue with your boiler!
  • There are issues with the accuracy or function of your thermostat: If your thermostat is saying 70 but you’re feeling more like a 50, the thermostat is almost definitely malfunctioning. This can be due to the thermostat itself, or it may be an electrical issue somewhere down the line. Our experts can tell the difference and bring you the repair service you need to restore your boiler.
  • There are odd sounds coming from your boiler system: Clanks, bangs, and pops are never a good sign. And with your boiler system they can indicate a variety of issues; anything from sediment in the tank, to damaged parts in the system. Either way, a fast response is critical if you want to avoid further damage!
  • Your boiler is heating poorly or unevenly: Even, strong heating is one of the best benefits of a boiler. So if you’re noticing cold spots, or some rooms are not getting adequate heat, you’ve certainly got an issue on your hands.
  • Leaks: Boiler system leaking? The causes are many, but they all point to one thing: You need professional repair, and fast! Leaks can mean more than bad news for your boiler. They can also lead to water damage in the home along the floors, in walls, and can even harm furniture and possessions. If you spot a leak, contact National Heating and Air Conditioning right away!

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.…
