We've all jumped into a shower one time or another only to be met by freezing cold water. While we may have blamed it on a relative for taking too long of a shower right before we hopped in, it may be indicative of another problem altogether: an inefficient water heater. Luckily, water heaters are one of our areas of expertise.

Amazing professional service will not disappoint. Actually focused on repairing my unit instead of trying to sell me a new one. The time will come when I do need a new unit but not yet. Air One Tech is definitely my to go place from now on with my current unit and when I decide to invest in new one.

Over the past few years I have used Air One Tech for all our heating and AC needs. I've had other firms but Air One Tech is far and above the others not only in technical competency but also in "easy-to-deal-with-ness", feeling that they really care about my satisfaction and they are cost competitive. For the past 3 years they have provided the regular maintenance for our heating and AC, and even installed a humidifier. They fixed things that were broken (on our outside AC unit) installed a new thermostat, and provided full explanations of the issues (with photos of parts and of our units) and

Consistently outstanding service from Air One Tech’s Dariush and team.
Over the years we have relied on their professionalism and responsiveness to service our old HVAC system and when it was time to replace it with a new one we knew who to call. Dariush thoroughly inspected our home and made thoughtful, educated recommendations. Also recently replaced a family member’s hot water heater.
All went very smoothly.
Dariush and his team are very knowledgeable and really care about what they do. Highly recommend!

Air One Tech has done an outstandingly professional job responding to my short notice request to service and flush my water heater. Alison was very courteous, informative, and simply pleasant to talk to. The technician notified us of his arrival in a timely manner and completed everything very quickly, but very thoroughly. After servicing, the issue was instantly resolved. We also received a very detailed report with pictures and recommendations for the future. Overall, a very professional service. Will refer to in the future.

Recently had issue with my heat pump turning on and off rapidly! first thing crossed my mind in the middle of all other problems was now I need a new heat pump right after replacing roof!! yes? NO! it turns out to be control board issue. even though it was not quite cheap, $500.00, was way cheaper than 10000.00 whole system!! courteous, detail service and quick repair! highly recommended!

I wish we could rate 6 stars... Our AC went out, and we called to get it serviced around 11am on a Tuesday. A few hours later someone was at the house! Unfortunately the system was shot (no surprise for a 20+ year old system), so we purchased a new one. The owner even stopped by on Wednesday with a portable AC to get us through, and they were at our house with the new system ready to install that Thursday at 8am! (Yes, you read that correctly. The new system was being installed within two days of our initial call).

The install went very well. The guys were professional, knowledgeable, and worked

I will not use another company to service my home system. The technician, Mr. Christmas, was outstanding. The owner is an honest man who worked hard to install my new unit and ensure that my home was respected and cared for. Top notch service. Amazing customer service and office staff too.

Same day service! We came home to a hot house and we had a newborn. They were able to send a technician out same day and replace what we needed. What a relief! The thermostat was reading 80 something inside the house!

We are so appreciative of the service Air One Tech provided!

Air one tech team was a life saver. I had a broken HVAC due to storms and kids and wife were in misery. Airone tech showed up same day I called, diagnosed and fixed the problem and got my family back to "life". They also saved me few thousands dollars by accurately diagnosing the real problem although there were a false positive about the compressor being the issue. I am glad I have a maintenance plan with these guys!

OK, this goes way beyond. I called them to schedule a maintenance check/service visit. I was a little concerned because it seemed a wet switch on our system had tripped; it's usually a false alarm, but I needed a pro to be sure in this case. They've already done excellent work for me, so I called them again.

They moved me a up a couple days sooner from the original date, since the unit wasn't working, but wasn't an emergency. This, in and of itself, was great of them, and I appreciated the priority service.

I also realized that the new date was my son's birthday - so

Air one tech helped me replace my ac unit last year, and I received a call for a complimentary maintenance check. I actually almost canceled my appointment because I had a very busy schedule, but I'm so glad I didn't. Sayvan came to do the checkup and he was super kind, helpful, and knowledgeable. He helped me figure out why it was so cold in my place when I had the heat at 75, and even helped me clean my incredibly dirty vent (which he certainly did not have to do). He is an amazing technician and I highly recommend him!!

I picked Air One Tech because they're certified for Trane furnaces, and I'm glad I did. I was able to get an appointment the same day. Dariush took the time to diagnosis the problem and explain the different options. After ordering parts, a technician returned the following week to do the repair. He was also courteous and professionaI. I agreed to maintenance plans (there is a separate charge for each system you have) which were worth it because they did much needed cleaning and patched up holes. After payment I immediately received an e-mail confirmation detailing the work done

I've probably used 4 - 5 different heating/AC type companies the past 20 years. I would have to say hands-down I've had the best experience overall with Air One Tech.

The owner is very responsive and incredibly knowledgeable. We had the team of Angelo and Amir come out and service and repair our heating/AC system and another time to replace our hot water heater.

They both are friendly and courteous and did an excellent job. Before they left they cleaned up everything and made sure all of our questions were answered and we were 100% satisfied. They make a great team and the owner
