Is This a Heating Emergency?

For Cincinnati homeowners, knowing how to identify a heating emergency is important. Getting prompt help can save you time and prevent further damage to your heating system. Key signs of a heating emergency include:

  • Unusual noises: Strange sounds from your heating system can indicate serious issues.
  • No heat: A complete lack of heat during cold months is a clear sign of an emergency.
  • Odd smells: Unusual odors from your heating unit could signal dangerous problems.
  • Frequent cycling: If your heating system turns on and off more frequently than usual, it might be a sign of malfunctioning components or incorrect calibration.
  • Yellow pilot light: A yellow pilot light instead of blue for gas heating systems can indicate a dangerous presence of carbon monoxide, requiring immediate attention.

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.…
