The problem of our AC system happened in the afternoon of last Sunday. As soon as we sent photos of the problem, we received an answer that we were scheduled for a Monday morning service. The technician came around 8:30 am and checked everything and then tested the system so we had it back to normal. It was very crucial because of the heat and humidity these days. Air One Tech's service has been extremely efficient and reliable. You can trust this company once you have a system installed from them, especially when you became a member.
Description of Work: The outside of the pipe for the AC/heating system was sweating and the temperature would not come down no matter how low you set.

I love the Air One Tech team, we've been with them since at least 2010, and there's never been a doubt. Their recommendations are solid, never an up sell, they take the time to not just do the job right (the first time) but also to explain stuff in plain English. It's clear they care about our stuff as if it's theirs. If not Dariush, the owner, my go-to is Fardeen. Not just because he's personable and polite. He obviously took notes when Dariush was training him because he's cut from the same cloth and is another rock star. Not a knock on any of the others, as i've met a bunch of 'em over the years. But Fardeen reminds me of my favorite tech.

I had my heater and air conditioner replaced by Air One Tech two weeks ago. I am very pleased with the entire process. Jack was very knowledgeable about HVAC products, and very professional in his dealings. He surveyed the site carefully, listened to my requirements, and took the time to educate me on the HVAC systems. I appreciated the very detailed proposal containing an itemized listing of the model numbers, photos and brochures of the units, the work to be done, rebates and discounts, warranties, etc. The installation was completed just 3 days after accepting the proposal. The installation team (Jose and Andres) wee courteous and efficient, completing the installation in one day and taking the time to patiently answer my questions. The front desk (Allison) was always quick to respond and very helpful. Post installation response to resolve a few loose ends has been quick. I would highly recommend Air One Tech.

Outstanding service, and the only HVAC company I'll use. Dariush and associates are thorough, patient, and very understanding. Switched to them after my prior company carelessly let all the refrigerant drain out of my old heat pump, and have never regretted the change.

Local company Air One Tech is the best. Led by CEO Darius Jamasb, this company bats way above it size providing a tailored, professional service with overselling. We searched long and hard before settling on this and we are so happy we did. Highly recommend to others planning to update systems.

The basics of the visit were great: punctual, efficient and polite. The technician, Fardeen, was terrific! He was very respectful of my working from home (mask, foot coverings, etc.), explained the details of what he was doing/issues he found and made recommendations for next steps. I would absolutely recommend Air One Tech (and Fardeen) for their professionalism. Great job!

Called them for an issue with my in home humidifier. They came out the next day and identified the issue. One day later (had to get part) my issue was resolved. The price was affordable and the service was prompt and professional. I’d absolutely call them again — recommend you do the same.

Air One Tech LLC is one of the three companies we received quotations. The Trane system Air One Tech recommended we thought was the best system according to the efficiency and price. What made us the happiest was the result we received. For the five months we used the new Trane air conditioning system, it saved us several hundreds of dollars on the electric bills. The services of the company is great. They responded to our service calls in very short time. The service calls were usually because of our lacking of knowledge to the new system. In short we are very happy with our new heating and air conditioning system.

We were quite satisfied. We had a standing contract with another HVAC service company and they were pushing upgrades and a new furnace on us and we wanted a second opinion. Because the other company had expressed a concern about "potential" carbon monoxide leakage, we were hoping for quick response on the part of Air One Tech. The owner himself came out to inspect the furnace within days of our call, and said that, while it is always recommended to replace a furnace proactively and that there were definite signs of age, the furnace is mechanically sound for now. He also pointed out (with pictures) evidence of blower deposit build-up (that should have been regularly cleaned under our contract with the other company) that was likely caused by an air filter housing that had never been resized after removal of an old electronic air filter and was basically allowing unfiltered air to get by. We were able to push back on the other company to do the work needed as part of their maintenance agreement and only waiting until their contract runs out so that we can switch maintenance over to Air One Tech.

Kayvan was excellent! Not only did he take care of the issue, he improved upon the control system for the humidifier connecting to thermostat. His work was neat and all wiring secured and well routed. I think Dariush and Kayvan really provide a higher level of expertise. My review above re price reflects more the entire install. When I chose Dariush and his company is was not based on the lowest offer but really his expertise. I think Kayvan as a field technician really adds to the company given his knowledge and pride in his work

It was easy to schedule an appointment with Air One Tech. Our technician, Kavon, was punctual and professional. He diagnosed the problem, gave us options for how to fix it, and then implemented our preferred option quickly. Our heat was back on before her left. I would definitely recommend this company for your HVAC needs.
