Heating Installation & Replacement

At some point, your HVAC or heating system is going to run itself into the ground from years of use or lack of proper maintenance. Like all working machines, it will be repaired until it can’t be. In this case, your home’s heating system becomes unreliable and requires replacement. Our technicians at National can walk you through the process of selecting and installing a high-efficiency heating system for lower operating costs, higher heating output, and improved airflow. 

Newer heating systems also offer:

  • Eco-friendly operation
  • Reduce repair costs
  • Whole-home heating efficiency

Ideally, you should schedule a maintenance appointment for your heating system at least once a year, and the best time do so is in the fall before winter fully sets in. If you use a heat pump, it should be tuned up twice a year, as it needs to heat and cool your home.

On average, furnaces last around 15 to 20 years, but this is dependent on a number of factors. Due to Ohio’s extremely cold weather, many homeowners in this area run their furnaces frequently, which will make your furnace’s lifespan shorter. Not keeping up with a regular maintenance schedule will also cause your furnace to not last as long.

The standard amount of time to replace most filters is 90 days. If you have pets in your home or members of your household suffer from allergies or other respiratory conditions, you will likely need to replace filters more often.

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.…
