FAQs

Routine maintenance is critical every year to keep your HVAC system in top operational condition. Beyond maintenance and tuning, call us at the first sign of trouble to prevent further damage and maintain control of your home’s climate.

It is crucial to find a system that meets the demands of your home based on size. A system that is too small can run nonstop to try to heat or cool your space evenly and sufficiently, causing excess energy consumption and high costs. If your system is too large, it may short-cycle. Short-cycling can cause stress on your system and lead to premature breakdowns.

We offer special financing on approved credit to help our customers spread out the cost of new HVAC installation services. Ask us about our financing so you can upgrade your system without breaking the bank.

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.…
