FAQs

Your furnace might make noise when it’s not running for many reasons. Air drafts through ducts may lead to rattling or whistling sounds, and metal components may expand and contract as the furnace cools down, causing popping noises. Electrical issues such as damaged wiring may result in buzzing or humming sounds. Clicking noises could indicate a faulty gas valve, and a running blower fan after shutdown may cause whirring sounds.

Ductless mini-split air conditioners have gained popularity among Ohio homeowners for their ability to create controlled temperature zones in individual rooms. This option provides energy-efficient cooling, helping reduce overall energy bills while ensuring a comfortable home. In addition to flexible temperature zones, these systems offer quick and affordable installation, efficient design, quieter operation, and straightforward maintenance.

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.…
