Nelson Air showed up on time, fixed my broken AC and installed a new thermostat. I thought I needed a new AC unit and thought it would be expensive but I only needed a small part to fix the unit. Very honest work.

The owner, Scott, was able to diagnose the problem with our unit within minutes and give us a detailed assessment of the issue. We were impressed with his professionalism, honest up-front pricing and efficiency in getting the job done in a timely matter. We'll definitely be back for his services down the road!

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!

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.

We have used Nelson Air for years for our HVAC maintenance. Most recently, Scott installed a whole house air purifier in our home. He is professional, reasonably priced, and great to work with. He doesn’t try to upsell. Highly recommended.

Scott Nelson was very professional, knew what he was talking about, and got our air conditioner fixed! So happy we have cold air now throughout the house. I would definitely recommend Nelson Air to anybody.

I've used Nelson Air over the years and they always provide excellent service! The technicians are always on time, very professional and knowledgeable. Thanks Scott for being fair, honest and for always going above and beyond to take care of my needs!

** First time using them, great first impression! **. The capacitor failed on my A/C unit. They arrived within the time frame they provided to us. Kept us updated and gave helpful suggestions how to maintain equipment. Planning on some minor upgrades and they will be the first I call and don't plan on wasting my time with other quotes. * without their service that night, our home was too hot be in. It was a simple repair and they solved the problem!
