It has been almost a year, and I have been extremely pleased with Big Air, I wish I had known about them sooner. I found Big Air on Yelp and reached out to them. They were fast and responsive; after explaining my situation, a representative - Matt, Miller came to look at my system. He was friendly, professional, and understanding. He provided me with a list of options and very reasonable quotes.

I greatly appreciated his honesty, so much that I opted to get a new system altogether.

Scheduling and detailing the work was very straightforward and quick. The technician Ernesto was also extremely professional; in addition to being on-time, he was very polite and performed the install quickly and efficiently. There was nothing more I could have asked for. Big Air's response time and quality service amazed me, and made me feel like a highly-valued customer, unlike my previous AC company who would not honor their own warranty.

Great experience from the estimate to the installation. A bit of miscommunication as far as scheduling a tech coming out, to the actual installation. The installers, Ernest and Flavio were great. Took the time to explain everything, answer any questions I had. Both very personable and friendly. My experience was that the company really cared about me as a customer.

They sent a tech out before the installation to see what would be the best way to install the AC. I felt confident they were knowledgeable and experienced. The only thing I would say as far as what they could have done better, was the person that came out for the estimate, I did receive a follow up letter thanking me for my business; it just would have been more of a personal touch for the person who handled the estimate to call, see how the installation went and a thank you.

Overall, it was a great experience and I would recommend them.

Game changers, sales guy was ok, but the crew that did our install...AMAZING!! Extremely professional, courteous, polite, through, I really can't say enough. That goes from the lead boss for the install down the new guy that our house was his first job. 4 new units and new ducting in the attic and craw-space, big job. They were fast, put drop cloths down to protect the carpet, and made sure to sea everything! Amazing amazing crew!

I am very pleased with the work done recently by Big Air. I submitted a request for a quote through Yelp. I got a return call the next day. I described my problem and the person on the phone described what most likely was going on. It involved leaking water and he reassured me that it was not an emergency and he scheduled a service call for the next week.

I had talked to one other company and their first appointment was two weeks out. He gave me a quote for a service call. I got a reminder call the day before the appointment with the name of the tech who was coming. The tech was on time for the service call. He was masked the entire time. After looking at the problem he outlined the steps for solving it and gave me a price quote for the first step.

About 40 minutes later, he was finished and the problem was fixed. That was a week ago and everything has worked perfectly since. If I have HVAC issues in the future, I will call Big Air.

Let me start by saying I love this company! They installed my heating and air 15 years ago and have always been able to rely on them when needed. The techs are always professional and very knowledgeable. I called them this past Tuesday cause my thermostat was cuckoo for Cocoa Puffs! Which means no air!! So the earliest they could be here was next Monday.

Well today I got a call from them saying they could have a tech here in 30 min. I was ecstatic!! The tech, Scott, was here and changed the thermostat, checked the heater and air conditioner and was done. I have air now and am overjoyed they came days earlier. Thank You Scott!!!
