Heating & Air Conditioning Services in Cincinnati, OH 45243

Madeira and Indian Hill stretch along some of Cincinnati’s busiest east side corridors, including Camargo Road, Miami Avenue, and Kenwood Road. Between older Cape Cod homes near downtown Madeira, larger properties throughout Indian Hill, and finished basements common around Sellman Park and McDonald Commons, homeowners here deal with a wide range of heating and cooling challenges throughout the year.

National Heating & Air Conditioning has been serving Cincinnati homeowners since 1930, and our technicians continue working throughout the 45243 area every week. If your furnace, AC system, heat pump, or water heater is struggling to keep up, call 513-621-4620 or contact National Heating & Air Conditioning online to schedule service.

A Long History of Serving Madeira & Indian Hill Homeowners

National Heating & Air Conditioning has been working in neighborhoods throughout Madeira and Indian Hill for generations. Homes near Euclid Avenue and downtown Madeira often date back to the 1940s and 1950s, while properties throughout Indian Hill tend to be larger custom homes that require multiple HVAC systems, zoning controls, and advanced humidity management. Our technicians regularly work near Miami Avenue, Camargo Road, Kugler Mill Road, and throughout the neighborhoods locals simply refer to as “The Village.”

We also service homes near Madeira Elementary, Indian Hill High School, and the residential streets surrounding Murray Avenue and Dawson Road. Because we already service so many homes throughout Madeira, Indian Hill, and the 45243 area, we understand the equipment setups, airflow problems, and seasonal comfort issues homeowners here run into year after year.

Air Conditioning & Cooling Services in Madeira & Indian Hill

Summer cooling problems throughout 45243 often go beyond simply replacing an AC unit. Older Madeira homes with original layouts can struggle with uneven airflow between floors, while larger Indian Hill homes may rely on several separate systems working together to cool the property evenly. National Heating & Air Conditioning provides:

  • AC Repair
  • Emergency AC Repair
  • AC Installation
  • AC Replacement
  • AC Maintenance
  • Ductless Mini-Splits
  • Heat Pumps

Heating Services in Madeira & Indian Hill

Winters in Cincinnati place a heavy workload on heating systems, especially in older homes with aging furnaces, original ductwork, or boiler systems that have been operating for decades. The colder-than-average winter conditions at the end of 2025 caused a noticeable increase in furnace strain throughout 45243, particularly in homes with older heat exchangers and neglected maintenance. Heating services available throughout Cincinnati’s east side include:

  • Emergency Heating Repair
  • Heating Repair
  • Heating Installation
  • Heating Replacement
  • Heating Maintenance
  • Furnaces
  • Boilers
  • Geothermal Service
  • Heat Pumps

Boiler systems are still common throughout parts of Madeira and Indian Hill, especially in older brick homes near Euclid Avenue, Given Road, and sections surrounding downtown Madeira that were built before central air became standard.

Water Heater Services in Madeira & Indian Hill

Finished basements are extremely common throughout neighborhoods near Camargo Club, Madeira neighborhoods off Hosbrook Road, and many homes throughout Indian Hill, which means water heater failures can quickly turn into expensive cleanup situations. We regularly help homeowners replace aging tank water heaters before leaks damage flooring, drywall, or storage areas. National Heating & Air Conditioning provides:

  • Water Heater Installation
  • Water Heater Repair
  • Tankless Water Heaters
  • Tankless Water Heater Installation
  • Tankless Water Heater Repair

Many homes throughout Madeira still have older water heaters approaching the end of their lifespan, especially in homes built during the post-war housing boom. Hard water buildup can also reduce efficiency over time and shorten the lifespan of heating elements and internal components. Tankless systems have also become more popular throughout Indian Hill and newer renovated homes where homeowners want longer hot water supply, improved efficiency, and more usable mechanical room space.

Commercial HVAC Services in Madeira & Indian Hill

Madeira and Indian Hill include a mix of professional offices, restaurants, schools, churches, and local businesses throughout the Miami Avenue corridor, Kenwood Road, and areas surrounding Madeira’s downtown business district. Commercial systems here often require careful maintenance because many buildings are older and were renovated over time. Commercial HVAC services include:

  • Commercial AC
  • Commercial Heating
  • Commercial Boilers
  • Commercial Heat Pumps

We regularly work with commercial properties that rely on older boiler systems, rooftop equipment, or multi-zone configurations to keep larger spaces comfortable. Churches, schools, and institutional buildings throughout this part of Cincinnati often require specialized airflow management because of tall ceilings and older building layouts.

Our team already works throughout Madeira, Indian Hill, Terrace Park, and nearby east side neighborhoods every week, allowing us to respond quickly when homeowners need service.

Homeowners throughout Madeira, Indian Hill, and 45243 continue choosing National Heating & Air Conditioning because we provide:

“Kevin Gaines is awesome. He’s friendly and so competent. He answered many questions I asked about the furnace. I had questions about the water heater as well and he went the extra mile to send pictures and get answers from the proper person. I’m sold on the company thanks to Kevin!”

Gerald Y. – Rated 5/5 Stars

“We couldn’t be more pleased with Kevin’s services this week. He assessed the problem for us on Sunday and had our heat pump back up on Wednesday. Kept the temperature needed in furnace mode in between. We’re in Florida most of the year, so we’re totally dependent on his skills.”

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.…
