I was extremely impressed many aspects of the service: promptness, courtesy, friendly communications, ease of scheduling, reasonable rates & no extra charge for weekend service. I will definitely call Alternative Air for any future issues with my HVAC.

This is my second review of Preferred Air! I still think they rock! My AC died! Time for a new one…read more They gave us a recommendation for a unit they said the owner had installed at his own home which was thousands less than other units. It was two days before they could install, however they gave us two free loaner window units which they came and set up for us in the meantime. When they came out for the install, we needed a small drywall repair which was anticipated and they had the repairman out the same day. They followed up the next day and one week later they came to the house for a follow up visit to ensure we were up and running optimally. This company was so impressive all their team members are awesome and helpful. Many years ago with my last AC install, the company that will remain nameless left a huge drywall hole and didn't patch it or have a recommendation for us. We also had issues with their company extended warranty which they stopped servicing. They sucked! Post sale support was terrible! So for a complete soup to nuts solution with top notch post sale service go to Preferred Air. You will be happy you did!

I received a text when Daniel was on his way and he arrived promptly at the start of the scheduled window. Daniel really took the time to listen to what I was looking for. After checking out the house, he recommended the right mini split heat pump size, the best placement options, and suggested a few upgrades to improve efficiency and save energy. He explained everything clearly and answered all my questions without hesitation. The itemized quote was detailed and easy to understand. It included everything from the heat pump, installation (materials and electrical), attic insulation, to even a Wi-Fi adaptor so I could control the system through an app. June 6th installation was quick and smooth, and everything worked perfectly right away. The condenser unit location was inconspicuous and protected from the elements with adequate airflow access. They helped me set up the app and even built an attic enclosure over the drop down stairs. Pricing felt fair and reasonable, especially for the quality of work they delivered. During the summer peak when it was 110+ outside, I was able to keep my garage at whatever temperature I wanted, which makes it usable year round and is a game changer in Phoenix. Daniel was professional, knowledgeable, courteous, and communicated really well throughout the whole process. I'd definitely recommend Preferred Air to anyone looking for an honest, skilled, and fairly priced HVAC company. I'll be using them again for any future HVAC needs.

I've told Kappa several times to cease charging me and refund the stolen funds, and now they've gone silent. I will be filing an ROC complaint against Joe Garcia, and any affiliated with Aire 1 LLC. The contractors also never kept their part of this bargain for semi-annual HVAC tuneups anyways, and their workers would constantly try and upsell unnecessary items at an obscene markup even though the system was brand new installed by this very same company. Scam artists, and apparently thieves. Kappa Air will also be receiving the same ROC complaint.

I used Aire 1 LLC for a couple years, despite some minor frustrations I had with them throughout my…read moretime using them. I'm a heavy advocate for supporting small businesses, and will always go to a family owned biz before a chain or larger conglomerate, and signed up for their "club" after their first visit to assist me, paying a monthly fee for white glove service. That being said, I cancelled my "club membership" last year, and will absolutely never call them back for assistance moving forward. Office/Scheduling - I repeatedly had trouble scheduling maintenance with them. If someone didn't answer when I called in, and I had to leave a voicemail, I would never get a call back. I had to be strategic to try and call when I knew someone would answer in real time. There were also at least two times to note where we would schedule a service window, and the technicians would not arrive within that window. One of the times I had to call back in to ask where they were, and they called the techs to go straight to my place next to assist me. The second time the tech called me right at the end of the window to let me know "they were on the way", and I told them not to come because I had other plans I needed to get to after that window and was waiting for them to come earlier. They said they would have the office call me to reschedule, and they never did. I didn't bother calling back to reschedule either, as it was just a check up visit that was offered with the club membership. Services - Every time the technicians came by, they were always very kind and friendly. I have no grievances with the staff as individuals. I first hired them to fix a leak in my A/C vent because the water was not draining through my wall to my bathroom correctly. They installed a motorized pump to force the water over the wall because the original installers laid the inner wall piping over a support beam in the wall, and the water essentially needed to "drain uphill", which was the cause of it coming back out my vent. Shortly after that, my A/C crapped out on me entirely, and I ended up hiring Aire 1 to replace the entire unit, inside my condo and on the roof. The very same day they replaced it, I needed to call them back in a couple hours due to an error that popped up on my (new) thermostat that the unit had shut off. The motorized pump they installed has a failsafe that will automatically shut off the A/C if it's imbalanced in any way as a safety precaution, and the pump was not staying as flat as it needed to be. They re-leveled it, and assured me it would not be an issue again. I ended up having to call them back out a few more times about this issue due to waking up too many times drenched in sweat because my A/C shut off in the night. They finally mentioned they could turn that setting off, so it wouldn't shut the unit off, and that resolved that issue. Final Straw - Last year I started to experience a water leak in my front door frame. This took weeks to diagnose where the water was coming from, if it was plumbing from my unit, from the unit above mine, etc. They finally were able to track the leak down to the drainage tube from my A/C into the wall that they replaced the previous year when installing my new unit. The technician had simply cut the tube 6-10 ft in length, pushing it all the way through the PVC pipe in the wall, thinking that would be sufficient to have the water drain downwards without coming back up. They did not bother to seal the PVC pipe at the end, where the tube was inserted (picture below). They came back, with their brother (since it's a family owned biz), to fix the leak. While they were here, they verbally admitted that they screwed that up and should have sealed that correctly when installing my new unit, and that it was "their bad". Mind you, I needed to submit a home insurance claim to fix this leak in my door frame, and this involved a drying and restoration company, and Aire 1. While everything was covered, I was still responsible for paying a deductible, which I assumed could be reimbursed by the party at fault. Fast forward to now, several months later, and Aire 1 is completely denying fault, and since I have no written admittance because the technician was careful to only admit fault verbally to me in person, I have no grounds to fight their claim. Now this may seem as "retaliation" for this factor, which is a fair and partial aspect of this review, but I assure you everything I've laid out is simply clear and factual to my experience with their services, and I only leave this as a warning for what you could potentially experience working with them. I try to avoid leaving negative reviews, but the way they've been handling things so poorly after I tried giving them chance after chance (amidst all the minor scheduling frustrations as well), I cannot sit idly without sharing my overall experience with them.
