This company did an amazing job!! My air conditioner broke the Tuesday before 4th of July, and it was very hot out. I called Nelson Air and requested a next day appointment on a very busy four day holiday weekend. The owner was very professional and 'fit' me into his schedule even though I requested a last minute appointment. The owner and his friend were honest and told me my options for fixing my air conditioner. They did a great job, and I would definitely use them again and/or recommend them to friends and family. Thank you!

Our a/c had failed us 3 times last summer, so we had been thinking about overhauling the whole thing for a while. When I scheduled heater maintenance around Nov, I met Scott, and I told him about our situation. He was very professional, knowledgeable and gave his suggestions without any pressure, which I appreciated. After sitting on it for a couple months, we finally pulled the trigger. Scott's team was very professional, courteous, and efficient.

In 2 days they were able to take apart and dispose of our old furnace, ac, venting, condenser, and replace them all. Additionally, they relocated the heater to the attic crawl space, so we got an extra closet! I cannot express how great everything came out. Scott and his team delivered everything they said they would, and helped give us peace of mind with the oncoming cold and hot days. I would definitely recommend Nelson air for anything heating or air conditioning related.

Highly recommend- great people and great work! We are lucky to have this company in our area to service hvac needs. So many companies send out whoever to look and guess what might be going on with your very expensive equipment and no layman really knows what problems may lie within the elaborate network of pipes, machinery and motors that sit outside the house and in the attic. This family knows their stuff and doesn't waste your time. My hvac purrs like a kitten now, and I know who to call if I want a no nonsense straightforward fix to whatever may be ailing my system (if it acts up again). Happy!

We used Scott from Nelson air to install a new hvac system at our home. We had 2 estimates and both were competitive but decided to go with Scott due to his professionalism and dealing with the owner rather than an hourly technician trying to upsell us. Also he's local to Yorba Linda which we preferred, we have no problem recommending. Service:A/C system repair

The team at Nelson Air is incredible. We worked with Scott to plan our full HVAC system update. He gave us a great quote and no hidden costs! Daniel did our install and he was outstanding - super clean, explained all the work he was going to do and had us up and running same day. We couldn't be happier with Nelson Air!

Nelson Air provided me with options and recommendations on a new unit. Scott was very professional and knowledgeable about the systems he offered as options. He did exactly what he said he going to do, and we couldn't be happier with his service. He was a pleasure to work with, and I would highly recommend him and Nelson Air to any of my friends, family or people doing research on different AC companies! Thank you Nelson Air!

I had a great air duct upgrade today from Nelson Air. They showed up on time, did a great job and cleaned up after themselves. I fully recommend their services.

I had a great experience with NELSON Air. A friend referred me to this company after my AC broke during one of our heat waves and I was desperate! They arrived the day of to assess and provide a quote and had my AC up and running in no time! Overall, I had a great experience with them and will definitely refer them to family or friends that have heating/ air issues.

I called Nelson Air to come to my business to give me a quote. I own a grooming salon and was looking to tap into my current air conditioning unit and run a duct into my kennel room, where we keep the dogs, so they would stay nice and cool as well. The owner came initially to give me the quote and the price was fair. We set up a time for one of his guys to come back to do the job. The guy that came was friendly and did a good job. Two thumbs up.

I dealt with the owner directly & I couldn't be more pleased with their work. They worked around my home remodel construction schedule which was extremely helpful.

Also, their prices are great! We replaced our entire A/C & Furnace unit with all the work being done in 1 day. I will definitely be recommending them!
