Professional Heating Services

The last thing any homeowner wants in the middle of a cold Clermont winter is an uncooperative furnace. A lack of heat is one of the most common repairs that National Heating and Air Conditioning makes. (And here’s a hint: check the filter. It could be so clogged with dust that it has effectively shut down your furnace.) Other types of repairs are just as common: strange noises, frequent cycling, or air flow problems. These issues point to some logical sources, but at National, we take nothing for granted: we check your ducts, too, knowing that deficiencies there can undermine your entire heating and cooling system.

Top-Rated Air Conditioning Services

Your air conditioner is capable of making more noises than an orchestra: clicking, humming and buzzing. It might rattle, hiss and whistle. Like all cries for help, you’ll want to address this quickly, as your air conditioner makes such noises only when something is truly wrong. Other problems won’t hurt your ears, but they should get your feet in motion, such as when your air conditioner isn’t turning on, your home isn’t cooling down properly, or air isn’t flowing as it should. Dirt and grime buildup causes some of these problems; electrical failures and refrigerant issues could be the blame for others. Our technicians have seen everything and are prepared to handle any issue. On top of repairs, our air conditioning services include:

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.…
