Description of Work: My heat pump was very old and had to be replaced. I called about 3 different contractors and found Air One tech to be suitable price wise and also had done maintenance work before. Overall, very satisfied with the service that Dariush and his colleague Mike performed.

Description of Work: Installed a Trane XV95 97% efficiency gas furnace and Trane XL16i Air Conditioner. Had to run new lines from outside unit to inside, due to kinks. Showed me how old line was pieced together with numerous connections - New line was all one piece, fewer points of possible future trouble. | Showed me on the old furnace where there were in fact 3 or more cracks in the primary heat exchanger. Explained the multi-stage heating of the new system and programmed my Nest thermostat to make best use of it. Clean professional crew. Sealed the existing duct work in the furnace area. |Recommended outside AC unit based on observation of trees over it, even though it was a less expensive unit, because it is better shielded from leaves and debris. |Dariush (the owner) was the one who did initial diagnosis of old (22 years) furnace. When I said I wanted to replace the AC as well, he sent me proposals for different units and explained the difference between them, and was onsite doing the installation job with 2 others. Very responsive via telephone and email.

Description of Work: Darius is great! Always easy to schedule, very responsive, and does great work. We started using Air One Tech as it was assigned to us by the home warranty company, and as we were happy with the quality of service, started using them for AC and heat pump annual maintenance as well. Highly recommend.

We had done some cleaning around our AC unit and our electrical wire got cut. He spent time tracking down where the problem came from and fixed it for us. He has been doing work for us for 3 years now and I highly recommend him to anyone. He is highly knowledgable and goes above and beyond every time I hire him. I have worked with quite a number of AC/heating companies, he is the only one that I will do business with after the very first experience.

We had AC issue on and off for a year.We tried different companies with no result. Almost two months ago we read reviews about Air One Tech and gave them shot to see if they can find the problem. Darius and Mike showed up on time-I loved that they already had their shoe covers on before walk in the house- Darius found out that compressor after working for few hours gets overheated and quit working!! seems simple but nobody got it before and as quick as this Company. After they fixed our problem I waited two months to make sure the issue was fixed permanently. We had more than four provider diagnosed the problem, everybody had different opinion! Scheduling with an AC company in the middle of summer is not easy but we were lucky to get Air One Tech come over and diagnose the problem. Since we have a very old unit, we got the option of changing it from everybody but Darius. He explained us the problem and fixed it. Fixing the problem took some time but he was following up with us and he kept his promise to fix it! Our AC is working totally fine now. There are something I'd like to say, this company is great!! it might be helpful for other people if they are kind of picky like me and my husband: 1- We had great experience with their costumer service. 2- Darius is very knowledgeable, experienced. and explains the problem elaborately. 3- He was ON TIME. They showed up the same day we were scheduled. 4- His price was fair and we are happy since other companies cost was much more! 5- More importantly; the problem is fixed permanently Air One Tech is a very professional company and we will definitely recommend it.

Two months ago, my HVAC started giving me problems - but it was an intermittent issue. Rather than thinking through the issue, Daryus quickly pointed me to an electrician and focused more on having me close the claim with HMS so he wouldn't continue to be bothered by their follow up calls. It turned out to be an HVAC issue - not an electrical issue - after all so I had to open up another claim. This time, Daryus didn't give me a date until five days out from the call. I called three times the day before the appointment and he did not call me back. He called the day of the appt and said he'd come over - I explained that the problem was intermittent and he told me to call him when the AC is next acting up and he'd try to come down. The next day the AC was acting up and I called him. He was inappropriate and used the word "naked" - referring to the need for me to remove clothing to cope with the heat unless I manually reset the AC - and he said it's ok if the AC's not acting up the next day as he'd just start replacing some parts that could be creating the issue. Well, when I called the next day, he said he can't do it since the AC was functioning! - if he'd told me this, I would have left the AC off for him to diagnose in "unworking" condition the prior day. When speaking with him, he told me "I have a call and will call you back" and then never did. He told me to just have HMS assign another company - which I did in the end. I cannot believe how non-responsive and unhelpful he was.... what I can't believe is that I actually continued to try to work with him for two months and the problem is still unresolved! I hope I find someone better next time.
Description of Work: The provider was assigned by HMS warranty company - and based on the reviews offered here by Angies list members - I thought it was a good choice. This was not the case. I was having trouble with my HVAC unit and Daryus gave me the run around and in the end I had the claim reassigned to another company. If you want to constantly chase your service provider and not get a resolution in the end, then go with this company!

We believe in quality work and being polite to all of our clients. I personally remember this client whom we gave her couple of hours free consulting over the phone to address her A/C issue without knowing her or asking for money. The customer was asking us to be there sharp at any time that she wants regardless of our availability. We simply explained that we need to diagnose the problem properly and it will take some time to resolve the issue,and since it is intermittent, it could be any thing including electrical or mechanical. She already had an electrician to check the system, it was not our recommendation. She canceled the appointment three times, first time because of trip, second time because she already had reset the system and third time she was not sure if she wants to spend to resolve the issue and she was expecting free repair!! Also we are professional contractor who does not use improper words. We never used word "naked" and it is made up.None of her comments are accurate and we are surprised to read them. She was/is asking too much and we couldn't accommodate all of her requests. Dariush

They respond fast and do professional competent work.
Description of Work: My furnace was not working and Darius spent over an hour doing diagnostics and finaly found that the only problem was a clogged pipe that provides a vacuum to the ignite switch. He only wanted to charge me $50 dollars but I insisted he take $100. What a great contractor!!

I chose this contractor after receiving wildly varying cost estimates and recommendations on how to proceed; I felt that this company provided the most candid advice. Installation was tricky because this was an old house with limited space and required putting service lines through walls and floors, then thru a crawl space and foundation to the outside. But the work was done on time and with no problems. My only critiques: --the thermostat was installed on a certain wall at my request, but I could have been warned that putting it directly under an air outlet was not a good idea (temperature fluctuates too much). I simply moved the thermostat. --one of the outdoor A/C connections would have been vulnerable to being bashed with a lawn mower; I fixed that by installing a permanent wooden barrier to prevent damage.
Description of Work: Retro-fitted complete a/c system to existing gas forced-air furnace, including interior coil, external compressor, thermostat and service lines and fittings. (l did the electrical work myself, however ... a dedicated 220 volt circuit to the outdoor compressor is needed. This also requires a building permit.)

Again thank you Darius for your adv0cating on our behalf.
Description of Work: Darius was called out by our Home Warranty company to diagnose our gas Furnace which had stopped working. He arrived within a couple of hours of the request and identified that the very old unit would need to be replaced. I found him to be very responsive and was a strong advocate for us in the ongoing discussions that ensued with the warranty company who was very slow to propose and acceptable solution. We are in a dispute with the warranty company now over the cost for replacement, but Air One Tech was extremely professional and held the line to the need for a replacement of the furnace as opposed to some half way repair of a 40+ year old unit that the warranty company was first wanting to pursue I ultimately chose a mechanical contractor with whom I had worked before, but I wanted to acknowledge Darius for number one standing up for doing was was right for the customer and not the warranty company and a high degree of professionalism throughout the experience.

The overall service was professional and timely
Description of Work: My furnace went out over the evening and i needed to have it fixed. I have a home warranty on it and the when I contacted them they put me in touch with Air One Tech. Air One Tech responded quickly and had my system up and running in no time. The Tech was very professional and explained each step as he went along. I would definitely use them again and recommend them to others.

Please see comments above.
Description of Work: Through our HMS Home Warranty, we hired Air One Tech to address a 1959 leaking heating unit in the entry way of our home. The technician came out fairly quickly after the initial call to inspect the heater. Originally, he said we would need to replace the unit, but after some research found that the unit is no longer made and there isn't a comprable one that would fit the space, so he decided the best route was to fix the leaking pipes and parts. The technician is very friendly, honest, and courteous and was nice to take the time to show us (as new homeowners) where our water shut-off valves are and other "tricks of the trade" about our boiler and heating system. (ie. where the shut off valves are, when to drain the unit, when to service the unit, etc.) The work was performed under the HMS warranty for new buyers, so we only paid $100 deductible, but the technician indicated work performed would have cost around $600 out of pocket. My only complaint about working with this company is a few communication issues arranging appointments and scheduling. We got the impression that this was not at all intentional, but rather a symptom of the fact that the company is a 1-man operation and he is simply very busy as the main provider for heating issues under local HMS warranties. He was very polite at all times and did return calls promptly. We would definitely hire him back again under HMS or on our own, and in fact plan to call him in the Fall to do our HVAC tune up/check up.

My heat pump had been making terrible sounds - bad enough that I think they neighbors were talking about it. I called my home warranty company to start the process of having the issue taken care of. They assigned me to Air One Tech so I called and made an appointment. To my surprise they were able to come the next day which fit my schedule. Dariush arrived and did a full system check AND explained to me what was happening in my system without being condesending. As a woman and a first time homeowner, this is important to me. Since I bought my home and previous owner was the one responsible for the major appliances, it's nice to know where things actually stand in terms of condition, etc. What really sealed the deal was when I mentioned that my exhaust hood over my stove wasn't is great shape he not only took a look but he fixed it by screwing it in place and adding the proper industrial sealing tape. I highly recommend Air One Tech and will be using them as my primary heating and a/c provider!
