Heating Repairs & Diagnostics

Our technicians perform comprehensive diagnostics using the most advanced equipment available. That allows us to identify the core issue and avoid only fixing a symptom of it. We complete repairs using high-quality parts and per all manufacturer warranty specifications. We will calibrate the system and test it thoroughly to confirm a lasting repair.

Watch for the signs you may need heating diagnostics and repairs:
  • Weak airflow
  • Unusual noises
  • Rising energy bills
  • Unpleasant smells
  • Short or long cycling
  • Inconsistent temperatures
  • Frequent pilot light problems
  • Uneven heated air distribution

System Installation & Replacement

Our company offers a complete range of heating replacement services. This includes conversions and upgrades. We manage all aspects of a heating installation from start to finish. That includes expert guidance during the equipment selection phase. Our team manages permits and oversees code-compliance inspections.

We balance air for ducted systems. We also test thoroughly and educate customers on using their new thermostat. Our experts install furnaces, hybrid systems, boilers, and many other heating solutions. We also install add-ons, including smart thermostats, bypass humidifiers, and zone control systems.

Investing in a new heating system can:
  • Lower your energy bills
  • Improve your indoor air quality
  • Provide safer and quieter operation
  • Reduce your household carbon footprint
  • Deliver faster and more consistent heating

Systems We Service Overview

We service all heating brands and models. This includes maintenance and repair services for both warranty-covered and non-warranty systems. Our heating services extend to hybrid systems, which pair a heat pump and a furnace. The heat pump delivers the primary heating while the furnace serves an auxiliary role. In our climate, the system must switch between those units at the right times.

The heating systems we service include:
  • Furnaces
  • Heat pumps
  • Geothermal heating systems
  • Ductless mini-splits

Emergency Service & Scheduling

If you need an emergency heating service, we recommend that you call us directly for the fastest response. Contact us anytime for emergency appointments, even on weekends and holidays. We offer same-day appointments for urgent heating problems and 24/7 emergency services. We will arrive as quickly as possible to get your heating back on in a reliable manner.

Examples of the heating emergencies we handle include:
  • Gas leakages
  • Burning smells
  • Visible damage
  • Complete loss of heat
  • Irregular system cycling
  • Carbon monoxide alarms
  • Low temperatures and weak airflow

Energy Efficiency & Rebates

HVAC manufacturers have placed great emphasis on energy efficiency in recent decades. Many systems today are much more efficient than the ones you bought last time. ENERGY STAR is a program run by the U.S. Environmental Protection Agency. It certifies the best performers in energy efficiency. Systems with this label can usually earn energy incentives from both government and private groups. Incentives can lower the cost of energy-efficient systems. They also help you get back your investment faster. Our team can help you explore those options and make the right choices.

There are many types of energy incentives available:
  • Federal rebates
  • Ohio tax credits
  • Federal tax credits
  • ENERGY STAR rebates
  • Manufacturer rebates
  • Utility and other local rebates

24/7 Emergency Heating Repair

Even if it’s the middle of the night amidst a severe snowstorm, we’ll come to your home to fix your heating. We offer furnace repair services for thermostats, flame sensors, ignitors, blower motors, and more.

Furnace Installation & Replacement

Our company offers a wide range of options for furnace installation from the top brands. Among the fuel-fired models, you have the option of high-efficiency systems. Traditional fuel-burning furnaces lose heat through the process of venting toxic gases. Condensing furnaces have a second heat exchanger to mitigate much of that loss. Some models feature variable-speed blowers, multi-stage burners, and modulating gas valves. They also include other enhancements.

Comfort Care Maintenance Plans

We encourage all Cincinnati homeowners to schedule seasonal heating maintenance. The ideal time to schedule a tune-up is early in the fall before the cold weather arrives. That said, if you miss that timeframe, it’s better to schedule later than not at all.

Most HVAC warranties require regular maintenance as a condition of coverage. Tune-ups improve efficiency, thereby lowering your monthly heating bills. Clean equipment promotes better indoor air quality. Well-kept heating systems need fewer repairs, last longer, and age better.

Seasonal heating maintenance is particularly important if you have fuel-fired heating. There are many malfunctions that can cause carbon monoxide to seep into the home. Those include cracked exchangers, gaps in combustion chambers, and backdraft scenarios.

We have a maintenance plan that makes seasonal tune-ups easier and more affordable. Membership includes comprehensive heating and cooling maintenance at a discount. As a member, you’ll also get many more perks at no extra charge. You get priority same-day status, a 15% service discount, and a $25 annual discount on new equipment.

Schedule Reliable Heating Help

Our company offers convenient scheduling by phone and online through our website. You can reach us any time of day or night if you’re dealing with a heating emergency. We often have coupons and specials available. You can find our current offers online. We offer free quotes for furnace installations. Plus, we have flexible financing options pending approved credit if you qualify.

National Heating and Air Conditioning is a local and trusted choice for professional heating services in Cincinnati. To schedule an appointment, call today or contact us online.

Frequently Asked Questions

We provide same-day service for urgent HVAC problems in the Cincinnati area. We focus on customers who need heating the most. We also have heating technicians on call at all hours for emergencies. If you lose your heat on a cold Ohio night, you need help fast. Even if it’s a weekend or a holiday, we are going to deliver that professional assistance.
You should schedule a seasonal tune-up for your furnace system once a year. The ideal time to schedule is in the fall before the cold weather arrives. That said, it’s better to schedule late than not at all. Most furnace warranties require seasonal maintenance. This helps lower operating costs, prevents repairs, and extends equipment lifespans.
Key factors to think about are the system’s age, the level of repair needed, and whether a warranty applies. Common problems with pilot lights, like being hard to relight, are often fixable. You can usually solve these by cleaning and calibrating them. Unpleasant smells and excess dust are problems we can often solve without replacements. Other signs can include unusual noises, weak airflow, and uneven heating.

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.…
