Signs Your Air Conditioner Needs Repair 

When experiencing air conditioner repair problems, you need to address them quickly before they turn into an even larger issue. Watch out for these telltale signs that you need home air conditioning repair:

  • Reduced energy efficiency: If your energy bills have skyrocketed, you might be dealing with an inefficient air conditioner that is overworking itself to keep your home cool. The older your system, the harder it needs to work to maintain the comfort.
  • Ineffective cooling: Has your air conditioner stopped working like it used to? If you’re no longer feeling the cool breeze flowing through your Cincinnati home, it could be because of wear and tear, component failure, or a clog!
  • Unusual odors: We all know that your air conditioner is likely to produce a musty smell at the beginning of the seasons. But if an unusual odor persists, you could have a big problem on your hands that requires professional help!
  • Odd sounds: Your air conditioner should be background noise, which is why loud banging, clanking, or grinding noises need to be addressed ASAP. If left unattended, a small problem can turn into a much larger issue!

How Often Should I Schedule AC Services?

National Heating & Air Conditioning recommends that you get your air conditioner serviced regularly. An air conditioner tune-up is a sure way to catch small problems before they turn into major AC repair problems.

If your AC unit is working well but has not been serviced in a while, give us a call. Believe us when we say that nothing ruins a day quite like having your air conditioner break down during a hot Cincinnati summer day.

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.…
