HVAC reviews in Irvine, California

Excellent customer service and HVAC Ricardo did an excellent job. All well done. This service was part of my warranty.

Today Antoine came and was The Most Professional Serviceman I have ever encountered.
His knowledge, warm smile and handled himself showing concern and respect.

The manager came to adjust the problem in reinstalling the new vent cover did great job as before too

Zachary was amazing from start to finish. Took the time to walk me through the process of getting a new A/C unit. Zachary had Hugo and his team come to install and they were great. Took the time to make sure everything was correct. Didn't speed to get the job done which I was thankful for that 🙌 I will recommend this team to family and friends.

Our Technician Carmelo was great. He took extra time to explain everything to us regarding our maintenance.

The technician Jesus Estrada is simply outstanding. He is the one who finally identified the source of the AC leak and fixed it. Experience, diligent and Very pleasant.
I have had at least 4 technicians come for a leak since the initial installation, he is the only one who accurately fixed the issue!
I am impressed and pleased!

Zacary Reyes was just so excellent with his service and knowledge. Anther crew will be coming this evening around 6pm to provide a better quote to possible replace a new air con unit.

At first I wasn't happy, because I had am appointment for the day before and had to call the nest morning to get someone out to take a look at my AC.
Now when Hugo got here, and doing his thing it was great. He knew what he was doing and talking about. And took his time letting me know what was going on.
Thank you

5 stars -Anthony came out to service my AC filter, and I was beyond impressed. He was professional, knowledgeable, and genuinely kind — not to mention incredibly respectful of my space. He took the time to explain everything clearly and made sure everything was working perfectly before he left. You can tell he really takes pride in his work, and it shows.

If you're booking a service, ask for Anthony — you’ll be glad you did. He truly went above and beyond. Five stars all the way!

May 2, 2025 (1 star): AC stopped blowing cold air right after the installers left. There goes $16,000. Guess I better call them to come back and repair my "brand new" AC...

May 23, 2025 (4 stars): Originally I had this place as a 1 star from DAY 1! The moment the "technicians" left after the installation, my AC stopped blowing cold air. I then called to report the malfunction. When the second technician came out (Richard), I already knew that I got a good technician, came prepared and knew what my problem was before he even started. I explained my situation and he stated that the communication wire at the compressor is improperly connected. He said that he just came from another job with the exact problem and ended up being the same solution. Once he corrected the wiring, the system blew cold air again! AND, to go above and beyond, he had a mild issue with accessing the wiring at the compressor because the previous installers didn't leave enough wiring to be able to open the panel freely. Richard went and ran new longer wiring to make it easier for him and the next guy to service the unit! I wish I could rate Richard alone, as he deserves 5 stars.

About the worst ac service and customer service I’ve ever experienced. Talk about incompetence, representatives have no idea what any other representative is doing. Took me several days to even get someone on the phone.
My ac cost me over $14,000. It took them 4 months to finally get the permit approved by the city of Huntington Beach. They constantly assured me that a technician would come; he never showed! Not a text or phone call. This happened several times. Waiting hours for someone to show up and no one came.
I dealt with this company for months. Every time it was a run around.
Don’t make the same mistake I made!
You will regret it!!!

I found GreenStar through a friend who had their rental properties HVAC replaced last year. I was pretty stressed out about the costs associated with repairing my home’s old system. After calling a few companies and getting ridiculous quotes, I gave GreenStar a call. I was able to set up an appointment the SAME DAY! One of their reps came out and listened to all of our concerns. The rep was super knowledgeable and understanding. I believe their name was Zack. We had a tech named Jose come out the next week and installed the new system. It’s been 3 months with zero issues. Our Reem system is great and we’re saving a lot on our electric bills already! Thank you GreenStar for the incredible service! I’ll be referring them to my friends and family as well.

I gave them a little rating because of the scheduling issues. I clearly told them I would not be available any day except the weekend Saturday through Monday. That evening I got a text message saying they were going to be there on Wednesday at 8 AM. I was able to change the appointment day, but then discovered that they put me down for having no cooling from my unit when all I was getting was a routine maintenance. The appointment was booked for between 8 AM. And noon. At approximately 11:45 they called and said they would need to change that to between 2 and 4 PM. They finally called at 4:45 and said they Were on their way. They finally got there at 5:30 PM. I will say the technician was very clean and seemed to be Thorough. When it was Right Time, they would replace the filter. They don’t do that now unless You have a filter for them to use

Our technician Hugo was very kind and was open to letting me shadow his assessment of our heater. I learned a lot and will use him for calls in the future.

This place lies. They sell you one thing and you get another after they say oh we can’t do that here. Sales person is just that a sales person. Once the job happens they run into a kinds of issues because they promise what they can’t deliver. Then you can barley communicate with them. All of there workers have no clue and complain to you the customer. Then the guy who was supposed to clean out my vents straight up lied to me about doing it. And old bloody napkins and cigarettes came up through my vents and into my little daughter’s room. As well as my own. Trying to get anyone to answer you is like trying to call up the DMV.. No one knows what’s going on. All around would not use them again. Also I spent 18k. Totally regret going with them.

I had a problem on Labor Day, where the air conditioner was leaking above our bedroom closet. I called them and literally within one hour. They were at my door. Very professional with text messages updating arrival time with the driver. A completely professional first class service.

Derek was great! Explained to me exactly what I need and I didn’t feel like he was trying to rip me off. Very honest and sincere and I truly appreciate that.

Antoine D. Lewis was a true professional. He did great work on our annual service, explained issues we might want to fix and respected our home. Thank you!

Hugo was extremely professional, respectful, and helpful. Quickly performed the bi-annual maintenance and installed new scrubbers for both systems. A pleasure to have him come out to our home.

The guys spent a long time installing the Ductwork. They did an excellent job and I would highly recommend them for their work and professionalism. Thank you guys for a job well done. As soon as the small bit of drywall in the garage is repaired by Greenstar the job will be a Hugh improvement to my AC system!

Excellent service. HVAC installation went smoothly. There was a minor issue that was resolved the next day. They respond promptly if you have any questions.
