Signs You Need to Replace Your Furnace

While not ideal, most homeowners wait until their furnace is flat-out broken before deciding to replace it — and it’s all too common for that time to be during a brutal winter. To avoid being frozen in your own home, there are a few signs to look out for when it’s time to replace your old furnace. These signs include:

  • Unit is over 15 years old – There’s no helping it when a furnace is at the end of its life span, so if it’s past its prime, it’s time to replace your furnace with a new model.
  • Unusually high energy bills – A malfunctioning furnace can lead to insane amounts of wasted energy, resulting in high monthly bills.
  • House isn’t warming up – No matter how long your furnace is running, your house doesn’t seem to get any warmer.
  • Odd smells and/or sounds – Foul odors or loud, annoying noises coming from your furnace are never a good sign.

Is your furnace not working as it should? Call our experts at National Heating and Air Conditioning to help! Dial (513) 621-4620 or schedule your service online.

Benefits of Getting a New Furnace

Just as there are clear detriments to keeping a furnace too long past its time, there are plenty of benefits to upgrading to a newer, better model. Some of these benefits are:

  • Energy efficiency – With newer models available, you can save on your monthly energy bills due to their optimal efficiency.
  • Faster warmup times – Get your entire home warmed up within the hour with a new and improved furnace.
  • No odd odors or noises – Gone are the days of banging, hissing, and clanking when you upgrade to a new furnace.

Plus, with a new furnace, you’d save on maintenance and repair costs, as it’ll be quite a long while before anything severe goes wrong. We also offer a one-year guarantee, so if you’re not a fan of your new furnace, you get a full refund — no questions asked.

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.…
