HVAC reviews in Cincinnati, Ohio

I had an absolutely outstanding experience with Nelson Comfort. The service technician from Nelson Comfort was courteous, polite and very knowledgeable. He showed up right on time and quickly fixed the problem I had with the air conditioner in my new house, and he took the time to explain and show me what I could do to prevent the issue from reoccurring in the future. I would very highly recommend Nelson Comfort. I've used Nelson Comfort for over 8 years and have always had very positive experiences.

Our tech, Zach, arrived as scheduled and was wearing a face mask, shoe covers and gloves. He was careful about social distancing.
This was a regular contracted call to service our AC unit, but he suspected a leak in the cooling coils (ice had formed on the bottom fins and tubing). He advised we would have no AC until he could find the leak, but he had another scheduled call.
Fortunately, he was able to return after his last call. He ran a leak test and found the AC coil would need replacing, but could not be scheduled until the parts came in. He completed our service check, adjusted our heat pump to give us some cooling (90+ degrees all week!) and cleaned up everything before leaving.
We were charged only $85 for the leak test and given a fair quote of about $1,300 to replace the coil and recharge the system (our parts are still under a 10-year warranty).
We hope Zach is assigned to our repairs when the new coil arrives. He was thorough, very friendly, professional and efficient. Nelson Comfort is lucky to have Zach on their team!

Update:
Another outstanding job done! My aging central A/C died at the start of a heat wave. Nelson Comfort exceeded again: Better quality equipment for less cost than the competition, installed promptly despite the busy season. They left everything tgey touched clean and tidy. The new system is performing perfectly. I shouldn't even bother asking other installers for quotes: Nelson Comfort is The Best!

Previous review:
I took bids from four installers for my new HE natural gas furnace, and Nelson exceeded all others. Courteous and helpful salespeople, by far the best equipment for the price, and they were energetic and flexible on the installation. They are at the top of my list for future installations, upgrades, and service.

Austin texted that he would be even earlier than scheduled time. Very professional, courteous & personable. Quickly diagnosed a/c problem & resolved the issue.

Nelson managed and installed Geothermal at my house which was totally renovated. The new system has been great and Nelson was extremely patient with me while renovations were going on. They worked around my schedule and made some good suggestions on changes to make while renovating. Our house is much more comfortable and even temperature. The geothermal works great, is very quiet and extremely efficient. I have already saved a bunch of money on heating costs from last year to this year and look forward to the lower power bills in the future.

Thanks for all the great service and suggestions!

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!

Kevin was extremely knowledgeable and experienced providing details about our ac system. He was courteous and professional. Great service technician!!

My experience with Nelson Comfort was positive from beginning to end. I have a 100 year old home that did not have central AC on the 2nd or 3rd floors and no simple way of installing it. The salesman , Greg, came up with a very creative way of positioning and installing all of the system components in closets and crawl spaces. These details were fine tuned by Greg returning to our house with an installer before ordering materials. When the work started we had 2 foreman, Keith and Elijah, and their crews working on our job. The foremen were polite, knowledgeable and hardworking. Their apprentices were polite and respectful as well. Working in a house such as ours with wood lath and plaster walls and ceilings is messy, but the crews did their best to minimize the dust and debris and cleaned up well each day. I am in the commercial construction business and know when a job is done well (or poorly). Our job was definitely done well. I highly recommend Nelson Comfort for new system installations.

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 visit!

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 figure out how to program and control various elements of my system.

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 professional. I will never use anyone else.

Chad is a repeat technician and does a 1st class job including the customer service. Seems like Ian is following in his footsteps with. A pleasant and courteous approach. Great team. Will have them back.

Today Nelson Comfort installed a replacement four-inch Aprilaire Media passive air filter to replace the 20-year old electronic air cleaner. They also installed an "I-Wave" ionizer internally to the airducts at the furnace, which cleans the air and kills pathogens. So the house should have cleaner air and also provide a measure of safety even against the COVID virus, which apparently the I-Wave will kill on contact.

The technician Tyler was right on time at 8:00am and finished his work ahead of schedule. He showed me the installation and his work and is very professional. I would recommend the company and their services. their technicians are always polite
and respectful of the house and wear booties and masks as well.

Today is another day, 3.17.22. Matt came out and arrived at 7:50am, right on time. I am remodeling the lower level family room, which on the last remodel did not include supply ductwork for heating and cooling. Matt installed two supply ducts and one return duct, and closed off an supply elsewhere and made a couple of other small repairs. He was very attentive, listened carefully, and took care of the little details. He was outstanding. Very pleased, Finished by 11:10am.

A/C repair service for a unit they sold and installed for me several years ago. They were easy going on the phone and onsite. They listened to me and worked with me (i didn't want to void my warranty, fixing a repair i could of handled on my own technically, by ordering a generic matching part online) w2They fixed the problem I had diagnosed quickly once they made it out here to service the unit.. I would of subtracted a star for that in my review, except I filled out a thing on their website for a free service call with any repair. The part was under limited warranty for 10 years. I ordered the unit 4-5 years ago. They indtalled it and carried parts on service vehicles for these Trane A/C units. In my case it was a bad capacitor for the outside fan. Onsite test and repair took 30 minutes or less and I only paid the limited warranty (predefined) price for that part, and the service call fee waived (for free). So, we were back up and running in no time after that. Been fine the last few days since the repair and it's only gotten hotter outside each day since. Thank you!

Kevin (tech) was very courteous, professional and through in doing fall maintenance on my Furnance. Very good job.

Matt was wonderful! He came out to inspect my mom's air conditioning units and did a great job! He is always so kind and respectful.

Nelson Comfort Techs Perry and Morgan showed up on time and ready to work. Both were GREAT!! My experience with Nelson was flawless and will certainly refer them to friends and family. This new Daikin FIT Heat Pump is awesome!!

Ethan was our service technician. Ethan was friendly and easy to talk to. He took his time to make sure the system was working properly. He was also willing to answer any question we had. We would definitely request Ethan for future HVAC services!

Ethan was amazing! He waited for me when I wasn't there when he arrived. He was so respectful of the house and property and very polite, professional and friendly. Thank you Ethan.

Jason G. is such a pleasant, easy going person to work with-he's been here for repairs as well as maintenance and I trust his opinion.

Love the geothermal unit BUT it has been a YEAR and if they don't respond to me (I have left 2 messages) about resolving how their contractor left our front yard, after he dug the trench for the unit, I WILL HAVE A BIG ISSUE. We paid them A LOT of money and expressed concern about this from the beginning. They said it would "settle." It hasn't. Now they need to address it.
