Discover the National difference when you call National Heating and Air Conditioning for AC repair in Campbell County.

AC Installation, Repair and Maintenance

When temperatures spike, your AC helps you stay cool at home. You shouldn’t hear any clanging, rattling, or hissing — those are all signs that something is wrong. Similarly, your AC shouldn’t emit any odors. Bad smells can mean there’s mold somewhere, or a small animal made its way in.

What’s better than addressing smells or sounds is to invest in preventive maintenance. Having one of our NATE-certified technicians do a tune-up in spring will prep your system for summer. We can find potential issues before they develop, stopping odors, noise, and breakdowns in their tracks.

Trust National Heating & Air Conditioning for all your AC needs.

Our Heating Services

Just as with air conditioning, your heating system should be quiet and odor-free. It’s not unusual to detect a burning scent the first time you use your heater for the season. That’s often just dust that stuck around. Otherwise, though, you’ll need a professional.

At National Heating & Air Conditioning, we can take care of all this and more.

Indoor Air Quality System Installation

Being comfortable indoors involves more than just your heating and cooling system. Particulates in your indoor air can contribute to discomfort, respiratory issues, and in the long term, even cancer. Because we keep our homes sealed to keep conditioned air in, ventilation may be inadequate. That means that indoor air is often more polluted than the air outside.

To help you with your indoor air quality, we offer these services.

Commercial HVAC in Campbell County

HVAC systems don’t just impact comfort and health inside of homes. They also play a large role in the comfort, safety, and success of businesses. Uncomfortable working conditions can hinder employee productivity. They can also impact customer behavior.

To help your business put their best foot forward, we offer commercial HVAC services, too.

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.…
