Green Air Engineering | HVAC in Laguna Hills, Heating Cooling Install & Repair Laguna Hills, CA

Nick responded immediately to our problem and did the troubleshooting to solve it. He has done this in the past as well. We have used Nick extensively for our heating and A/C equipment, installation and maintenance and have been very happy with his outstanding service and quality of work.

Everything about Green Air Engineering is tops! Nick is extremely knowledgeable, reliable, honest, caring and meticulous. He and his crew are true professionals. They installed a brand new furnace, AC, and ducting system in our house, far nicer than what we had before, in just 2 days!
Everything turned out better than what we expected. They took care of all the details and the work they performed was seamless. Nick’s attention to detail and project planning is first class and it was a pleasure to see how skill and professionalism transcended with all the crew members. He treated the project as if it was his own and as a result, we LOVE what we got!
Don’t waist your time with any other company. Nick is the real deal!

Nick was exceptional! He was knowledgeable, excellent at explaining options, kind and personable. HE met his quote for expenses, was accurate on expected time frame to recieve and install and trustworthy. He did above and beyond what was required. I will highly recommend him.

Nick is an HVAC PRO by all means. He asked me a couple of questions and quickly figured out what type of heating system we have. He then provided simple and clear instructions for me to solve my issue myself, saving both of us time and me money. Needless to say I have found my HVAC guy for as long as I live in the area. Will hire him without a doubt to tune up and maintain our system routinely.

PS. He even sent me an edited photo, showing me exactly what I need to do!

I got three quotes for our home AC replacement. Green Air Engineering gave me the best price and the highest quality for a customized system. I went with a two-stage furnace and compressor and can not be happier. They helped me with the permit, did the job in one day as planned, replaced flex dusts in the attic, and arranged for the HERS testing by third party. Nick the owner stopped by in a week to tune up the system to our test after a a week of trial run. He was responsive and professional a few times I called him with questions. I highly recommend this business.

We have worked with Nick in the past and have always had great experiences. He shows up on time, does what he says and shows pride in his work. We recently hired Nick to replace two complete systems. Installation went smoothly and on schedule. We had an issue with one of the units shortly thereafter, but Nick came out the next day and took care of it. He stands behind his work. Highly recommend.

Nick was very knowledgeable about my A/C installation, and was able to quickly diagnose and solve my problem. I can strongly recommend Green Air Engineering

It was time to replace our AC units and we interviewed lots of companies. Green air came highly recommended, and for good reason. Highly knowledgeable and professional. Great attention to detail. They explain all the options and give you choices, and talk you through the different choices. The install was easy. The crew was courteous. We have now had our AC for 2 years with no problems. Highly trusted and professional . I’d recommend them to anyone. 5 star service !

Just a note to say thank-you NICK FALLAH for the wonderful service Green Air Engineering provided. I have been a long standing customer of Green Air Engineering . It is a real pleasure to have an A/C and heating service you can really trust. The work has always been performed in a timely manner at a reasonable price.

Nick was very helpful. He advised us with an immediate quick-fix of our failing heater over the phone, even though we called him during Thanksgiving and we were new customers. Next week, he fixed our heaters properly and they work well since then.
