Furnaces are workhorses, but they don’t last forever. The U.S. Department of Energy recommends replacing a troublesome furnace if it’s more than 15 years old. When the time comes for you, you can depend on National Heating and Air Conditioning to correctly size your furnace. If you buy one too small, it will run longer than necessary to reach the thermostat setting. And if you buy a furnace that is too large, it will reach the desired temperature too quickly and then abruptly shut off—a process that is called short cycling that will prevent your home from heating properly. It can undermine the efficiency of a furnace and compromise its lifespan. Sizing a furnace accurately takes time, but we will always take the time to get it right because your comfort depends on it.

Besides furnace installation, we offer:

Air conditioners don’t last forever, either, but you can beat the odds with diligent maintenance. We recommend replacing an air conditioner if it is more than 10 years old.

Add on improved indoor air and more consistent indoor temperatures and you’ll understand why many Campbell residents consider a new air conditioner one of the best investments they’ve made in their home.

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.

We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
