Signs That You Need HVAC Service in Cincinnati

When there are problems with your heating or cooling system, there will often be symptoms prior to a complete breakdown, such as:

  • Poor performance: The system may not heat or cool effectively, or it may produce uneven temperatures.
  • Reduced airflow: Clogged air filters or obstructions can cause reduced airflow in one or more rooms.
  • Higher utility costs: A poorly-performing system will use more energy, increasing your heating and cooling costs.
  • Strange noises: Noises like screeching or screaming could indicate AC compressor problems, while thudding could indicate broken belts and banging or booming sounds could indicate furnace combustion problems. Any noises that are new or suddenly louder could signify a problem.
  • Strange smells: Excess smoke or fumes could indicate furnace or boiler problems, while burning or melting smells could indicate electrical problems. Musty or stale smells could indicate duct contamination.
  • Excessive dust: If you find yourself dusting more frequently than normal, your air filter may be clogged or there could be duct leaks.

If you notice any of these signs, or your system fails to start at all, contact the team at National. We can quickly diagnose and repair most heating and cooling problems the same day, minimizing your discomfort and inconvenience.

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.…
