Common Signs You Need Heating Repair

Your heating system often gives early warning signs before a breakdown occurs. If you notice any of the following issues, it’s time to call for professional help:

  • Uneven heating: Some rooms feel warm while others stay cold.
  • Unusual noises: Clanging, banging, or rattling sounds could indicate loose parts or motor issues.
  • Rising energy bills: A sudden spike in energy costs often signals a system running less efficiently.
  • Frequent cycling: If your furnace turns on and off repeatedly, it could mean a problem with the thermostat or internal components.

Addressing these symptoms early can help prevent more expensive repairs later on.

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.

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.…
