Reviews of local pros in Blue Ash, Ohio

Kevin came out to my Mothers house to do a cleaning he was thorough and honest and knowledgeable. Answered all my questions and recommended some good ways to keep the system in good shape.

We started with Nelson, and are happy with the continuing good service from National. We have a service contract. Our recent furnace service was easy to schedule, and the technician (Kevin) was on-time, professional and explained everything very clearly. Excellent service- thanks!

Chad and Austin did a very good job when they came out and serviced my air conditioner and I was very pleased. On my next appointment I would like those two to come out. Thank You Very Much.

Johnathan was so awesome!
The whole National Heating & AC team was really great. From scheduling, answering phones, coordinating, etc....all of it. The whole process was wonderful; all led with kindness and integrity. Something we need more of in this world.
We really appreciated them as a whole, and a special appreciation for out technician who was kind when answering questions, was patient with us, and very honest with his work and what he had to do. Made us feel blessed. Thank you Johnathan.

Jonathan Eaves was very friendly and helpful he knows what he's doing I'd refer him to family and friends

The National Heating And Air-Conditioning gentlemen was very nice. Had great Manners I give him a two thumbs up

Kevin Gaines with National Heating and Air was out for routine maintenance on our furnace. A couple of issues were identified and Kevin was able to get back on the same day with parts and took care of the issues.
Kevin was prompt and professional.
Thank you Kevin!

Kevin was great! He did a thorough job and even took out the trash he created. Would recommend him again

I was having issues and national was amazing! Keith (and Eric) were fantastic. They located an issue and fixed it. They were nice, patient, helpful and quick. I highly recommend using National. Great service all the way around.

Matt was incredibly helpful, explained each part of the repairs, and made sure that everything worked well.

Matt was very nice, professional and competent. He figured out the problem and fixed it!

Great company that really educates their customers. I never felt pressured and was informed every step of the way. Jason was great!

National Heating and Air, I couldn't be more impressed. From the moment I contacted them, their team was responsive, professional, and incredibly knowledgeable. They took the time to assess my needs, explain my options clearly, and provide a fair, transparent quote.

What truly stood out was their attention to detail and commitment to doing the job right. The installation crew arrived on time, worked efficiently, and left my home cleaner than they found it. They treated my home with respect and ensured I understood how to use my new system before they left.

Since the installation, my home has never felt more comfortable, and I’ve already noticed a difference in my energy bills. It’s clear they care deeply about customer satisfaction and stand behind their work. I highly recommend National Heating and Air to anyone looking for quality HVAC service—they've earned my trust for the long haul.

He did a great job, was very personable and answered all our questions. Why would I have pictures? Either

These guys were great. Stepped in and helped us with a tough project. Finished ahead of schedule and on budget!

Kevin was kind and professional. He took time and care in getting the issue sorted and explaining it all to us. We highly recommend!

Kevin G. came to my house for an HVAC call. He was very professional, respectful of the environment, and explained every step of the process to me . Thank you Kevin

Keith Brockman and Branden Meadors were absolutely wonderful. They installed our new heat pump with no fuss or mess and answered all our questions in a simple and practical way. I can hardly believe how painless it was to have a new system installed. Of course, our existing ductwork and electric service were adequate to this much more powerful and efficient unit than our previous one, but even so I think it was Keith and Branden who made this transition so easy for us. Their professionalism left us with a lot of confidence in our new system.

Jonathan has been doing excellent work for us for many years, twice annually. We are always glad to see him and feel confident that our geothermal system is in good hands.

Chad did a wonderful job today on repairing my boiler furnace. My 2nd floor was cold and now working great. Thank you

Kevin was great: professional, friendly and did a great job serving my furnace, even noticed that I needed to replace my humidifier filter which had signs of mold. Hoping we get him again in the Spring when it’s time to service our AC unit!
