Armen (kneeling) with his brother working tirelessly on my condo roof in West Hollywood.
Mike F.

I could not have been more fortunate to find Air-O-Tech! Armen responded right away when my ancient HVAC dropped dead. (During a heatwave!) He made a thorough, same day inspection , but couldn't save my existing 1980's rooftop unit. Two days later I have a new, efficient HVAC system. Price was fair & installation was seamless. Air-O-Tech is now my go-to for all HVAC service.

I was working with Armen from Air o Tech on a multi unit property, he had installed multiple split AC units. The AC units only lasted a few months until they started giving multiple issues. Armen has since completely ignored all phone calls and texts regarding these repairs. I have called other AC companies to look at the units but Armen is the one who set up these units and they do not want to take up the responsibility. I am willing to pay for these repairs because I've been receiving non stop complaints from tenants. Nonetheless Armen refuses to even pickup or respond, and he promised warranty on all these items which he did not honor. I gave him the benefit of the doubt and waited months before writing this review. Hopefully you reach out and fix the AC units I paid thousands of dollars for.

This past Sunday, late afternoon we went to an early dinner, the air conditioner was set to 73, and upon return, it was 80. An hour later it was 83, and I panicked. My father was expecting his first ever FaceTime call from his brother and I needed to find out why the fan was blowing HOT air. So YELPEd I did. I received 6 responses with AIR-O-TECH being one of them. Armen both owner and the licensed contractor who came out requested more information. I texted it ( but to the wrong number and my dad had his FaceTime Call). Armen said if it was not so late he could have come out tonight. Let's make it tomorrow morning between 9 and 10 am, I have to make a delivery first. Of the other 5 responses, they stated tomorrow day. No time. He texted that he was 30 minutes away, and put on clean booties to protect my floors, and a clean mask, to protect my health. At the time of the text, Armen stated a price for the estimate, explaining that it takes his time to drive to my home and to find what is wrong. His was right in the middle of the others. When he found the piece, he explained that it may just be that piece, but it may not. He could fix it and then have to fix another and another, etc. Asking his opinion, we decided to change the entire heating and air conditioning unit. He stated that his company had an opening on Wednesday, and that was the most optimal day for us. He needed to rent a crane, and he and his contracting employe removed the old and installed the new with precision and were extremely neat, organized, clean, and respectful from the first message to the receipt. They even gave a one year LABOR and ten years PARTS guarantee. He threw in a FREE air conditioning pad, and showed me how to operate the new update equipment. Pluses going with AIR-O-Tech: Very Responsive to YELP REQUEST, gave a WRITTEN ESTIMATE in line with the law; SAID A DAY AND TIME and ARMEN messaged 30 minutes prior to alert us that he was on the way; USED A CRANE; ; WAS VERY NEAT, CLEAN, ORGANIZED, WELL GROOMED, WORE UNIFORMS SO YOU KNEW WHO WAS ENTERING YOUR HOME; GAVE A WRITTEN RECEIPT FOR ONE YEAR LABOR AND TEN YEAR PARTS GUARANTEE; LICENSED, SAID IT AND DID IT. Would I use them again. ABSOLUTELY. THIS WAS MY DADS HOME. MY HOME NEEDS POSSIBLY A NEW AIR CONDITIONING UNIT TOO. POSSIBLY EVEN A BIGGER ONE. HIS WAS A 4 TON UNIT, and I HAVE A 3 TON THAT HAS GONE OUT ( and a home that is larger). My only compliant is that they don't do EVERYTHING IN THAT THEY APPEAR TO BE VERY HONEST AND WE ARE VERY HAPPY WITH THEIR SERVICE. July 11, 2020 Although Armen and his brother are fantastic, I have a very difficult stressor going on with family, specifically my father, as a result, I forgot how to change the filters On the new Air Conditioner and Furnace, Armen, and his brother installed, and they even left an extra filter and demonstrated but my father was just getting out of the hospital and I did not focus at the time. So I called tonight, left a message and Armen returned the message within a couple of minutes I am very grateful that I chose a great company with an owner who stands behind his product and even responds so quickly to questions that his past very satisfied customers have Once again Armen a GIANT THANK YOU!!

He plugged his machine into the unit and found the problem immediately. A very nice guy as well.

Armen was great! I contacted multiple air-conditioning and heating people to fix an AC unit that was not blowing cold air and they all said I would have to wait 2 days but Armen said he would be over in a couple hours. He arrived and within minutes he found the problem and then also told me that my unit was not a good brand and I suggested that I get a better more efficient one. I will be working with him again to replace this unit and other units I have. Highly recommended!

I finally found someone in the AC repair industry who's trustworthy & reliable! Armen arrived to my home ready to fix what he initially thought was the issue with the AC unit. He tested out the new parts he brought to discover it was a much bigger problem... the compressor in my system was blown. He said he wouldn't be able to get it working without it. So either new compressor or new system. Either way, it sucks. He was very gracious about the whole thing however, and only charged me a low fee for diagnosis despite being out on my hot roof for a couple hours. I'll probably be hot around here for a while but I'll rest assured at least I didn't get ripped off! Thanks Armen!!

Amen wrapping things up in this heat! Thank you good sir!!!

See all

I can't say enough good things about Ed and Ed Brothers. I've had air conditioning in my home for…read moremore than 30 years, and this is by far the best air conditioning company I've ever worked with. Ano, the office manager, is fantastic. She is professional, responsive, and incredibly efficient. Calls are returned promptly, appointments are scheduled quickly, and everything is handled exactly the way you hope a service company will handle it. Greg, our service technician, was awesome as well. He texted with his ETA, arrived when expected, diagnosed the problem, and got everything moving immediately. The necessary part was ordered, and they were back the very next day to install it. Everything was handled professionally, efficiently, and quickly--and most importantly, my air conditioner is fixed! It is so refreshing to work with a company that communicates well, shows up when they say they will, and simply gets the job done. Thank you, Ano, Greg, and everyone at Ed and Ed Brothers. Outstanding service from beginning to end. Highly recommended!

I got quotes from 3 other companies and Ed & Ed offered the most superior brands (for the heat pump and compressor) at a very great price. Ed and Edmond were so patient with me, always answering my questions and taking the time to speak with me as questions arose prior to the installation. As for the installation, the project was headed by Vic who was excellent, respectful, thorough and patient. All of the workers were really excellent and polite. I'm very happy that of all the companies I went with Ed & Ed!

Thus, when our 20+ year AC unit went south on us recently, Manny's was the first place I called. After giving a quite reasonable and competitive estimate, I set things up with Cecelia....who arranged to have Andrew and his crew come out several days later. Along with arriving right on time, they worked fast and diligently moving out the the very large and heavy unit that I've used for many years, and then setting up the new one. In this regard, I should also mention, on Manny's advice, we switched from gas to electric...which seems to work far better than our previous unit which relied on gas. In addition, given the fact that our ducts were showing some of the wear and tear of the past 20-years (which included a few puncture holes in them), I arranged to with Manny to have a crew return to replace them. Again, the pricing was competitive and the job was done in less than a day. It's also worth mentioning that along with a very polite and courteous crew, everything in our backyard was left exceptionally clean. In any event, for anyone looking to replace their AC unit or simply in need of some general repair on their AC system, Manny's should be the first place to call. Their expertise, service, and prices can't be beat!

I am so happy we found Robert Hall and Sons!…read more We had a very old, but still working, HVAC system. This summer, after going through our warranty company for a check-up, the technician ended up blowing our compressor. We then spent four visits trying to get the AC working again. It never did. Unfortunately, we realized too late that we had been completely scammed. While trying to get it fixed in August, we were also ghosted by another company right in the middle of a heatwave. Needless to say, I was stressed and overwhelmed. At that point, we decided to replace the entire system because we no longer trusted putting more money into repairs. That is when we called Robert Hall and Sons. Mike came out for an estimate, and right away, we felt like we were in good hands. He patiently answered all of our questions and, true to his word, we had a written estimate a few hours later. The estimate we received was beyond reasonable. After we submitted the signed contract, we were scheduled for installation about a week out. A few days later, I saw that another extended heatwave was in the forecast. After everything we had just gone through, I was not prepared to go through it again without working AC. I explained the situation to Mike, along with our HOA requirements, and he worked with us to make sure everything could be done as quickly, quietly, and efficiently as possible. His crew was amazing. They worked quickly, but thoroughly, and had the entire system installed in under three hours. I honestly could not believe how smoothly everything went. I cannot stress enough how professional Mike has been throughout this entire process. After the nightmare we had just experienced with other companies, it was such a relief to finally deal with someone who was honest, responsive, and did exactly what he said he would do. We now have a new HVAC system, a cool house, and peace of mind. Most importantly, we trust that if anything does go wrong, Robert Hall and Sons will be there and make it right. I would absolutely recommend Robert Hall and Sons. After everything we went through this summer, finding a company we can actually trust means everything.

Excellent service! They came out right away and gave us a very detailed breakdown of the work that…read moreneeded to be done. We got several quotes and decided on RH&S due to their great reviews and especially because they offered a two-year warranty instead of just a year for labor like the others. Would definitely recommend them.
