Highly recommend High Side HVAC for anyone needing fast, affordable, and professional AC repair in Irvine. We'll definitely be calling him again for any future HVAC needs!

I can't recommend Nick and the team at Alpine Heating & Cooling highly enough!…read more We had an issue with the A/C in my office, and the first contractor we called quoted us approximately $7,500 in repairs. Based on that assessment, I had already purchased a new unit and contacted Nick to handle the installation. Thankfully, Nick took the time to thoroughly inspect everything before moving forward. Instead of replacing the system, he discovered the problem was actually a very simple fix. Rather than selling me something I didn't need, he was completely honest, made the repair, and only charged me for the service call. His integrity literally saved me thousands of dollars and spared me the hassle of going through my HOA's approval process for a new unit. That's the kind of contractor you hope to find but rarely do. Nick was honest, knowledgeable, efficient, and professional from start to finish. My office A/C is now working perfectly. If you're dealing with any heating or air conditioning issue, call Alpine Heating & Cooling first or at the very least, get a second opinion from them before committing to expensive repairs. It could save you a tremendous amount of money. Highly recommended!

Alpine Heating and Cooling completely redid the HVAC system in my home, and I could not be happier…read morewith the results. Before working with them, we barely had any cold air blowing upstairs and our system constantly seemed to be having issues. Nick quickly discovered that we had the wrong size unit installed in our home -- a 3-ton unit when we actually needed a 2-ton system. He also found that much of the previous installation had been put together incorrectly, which explained why everything kept breaking down and never worked properly. Nick truly has a passion for what he does, and both he and Alex are absolute masters at their craft. Since installing the new system, our home stays perfectly cool whenever we need it, and everything runs exactly the way it should. I can't say enough great things about Alpine Heating and Cooling. Their knowledge, professionalism, and attention to detail were outstanding from start to finish. I'm extremely glad I chose them and would highly recommend them to anyone looking for honest, skilled HVAC professionals.

The day after we returned from vacation our ac went out during the hottest two weeks we've had this…read moreyear. It was a VERY old unit so we knew it was probably time to replace rather than repair again. I placed a service request via Yelp the next morning, responded to two of the half dozen companies that reached out and scheduled them to come the next day to provide estimates. Hana Hou weren't in those two, but the owner followed up on the next day and offered to be of service; review any estimates I got and provide some honest feedback. First company comes out. Nice, professional guy. Agrees that it's probably in our best interest to replace as a repair would've been around $2k, and we're still going to need to replace it within the next few years. We decide to continue with replacement. He leaves. His company sends a replacement quote a few hours later. Estimate seems a bit high, but what do I know? I send it to Bill at Hana Hou then wait for the guy from the next company. Next company comes out. Another very nice man. He completes his inspection, then sits down and and gives us three options. The highest cost option is $3k under the first company. But the catch is they can't do it until 10 days later. It's over 90° in my house when he delivers this news. "Yeah, we'll keep you on the list," I say. I send their quotes to Bill at Hana Hou, who loops in his expert Marc who tells us he can install a new unit THE NEXT DAY. He's 1 city over from us and just wrapped his last appointment for the day. It's 93° in our house. I'm honestly pretty desperate. Marc comes through. Inspection, FIVE options, we decide on one (not the cheapest we've seen all day,, but not the most expensive either). I sign the paperwork and he leaves. We go to a local hotel, and Hana Hou starts work the next morning at 8am sharp. Come home from work that night to a comfortably cooled home. (My husband said our installers Steven and Josh were great! Very personable, hard working and had great communication.) It honestly seems like there are quite a few great companies in the area. Even the most expensive option seemed like they were just riding the market at its high point (heat wave). But I recommend giving Hana Hou a shot. I'm extremely pleased with their work and the price I paid for it.

Extremely disappointed with NexGen's protection plan…read more I paid for this membership for over two years because it included things I actually used -- my annual tankless water heater flush, A/C check, and replacement A/C filters. Now, apparently, those benefits have changed. Filters are no longer included and the water heater flush costs extra. What really makes me angry is that I do not recall NexGen ever notifying me that the benefits I was paying for had changed. They even called ME to schedule my annual water heater flush through my membership, only for me to find out afterward that I would now have to pay extra for it. So what exactly am I paying for? To make matters worse, nearly every service visit seemed to come with a new list of recommended repairs or upgrades costing anywhere from hundreds to thousands of dollars. At a certain point, it becomes very difficult not to feel like the membership is more useful as an opportunity to sell you additional work than as an actual maintenance plan. If NexGen had simply been upfront and notified customers that the plan was changing, I could have decided whether it was still worth paying for. Instead, I continued paying for a membership based on benefits I had received for years, only to discover they were no longer included. Based on my experience, I would absolutely not recommend this protection plan. Save your money and get everything they claim is included in writing before signing up.

I've now worked with Ali and ARA Heating & Air Conditioning on two different homes and two very…read moredifferent HVAC projects over the last couple of years, and I can't recommend him highly enough. The first project was at our condo near South Coast Plaza. It was a complicated HVAC installation, and what stood out immediately was that Ali wasn't just trying to sell us equipment--he acted as an advisor and consultant throughout the process. He helped us understand our options, was very fair about what we actually needed, priced the project competitively, and then went above and beyond during the installation and afterward to make sure everything was done correctly and that we understood the system. When we recently moved into a townhouse in Fountain Valley, calling ARA again was an easy decision. This house presented a completely different challenge. It wasn't originally designed around air conditioning, although AC had been added at some point, and the existing system and airflow--especially to the upstairs--left a lot to be desired. Ali took the time to understand what we were trying to accomplish rather than simply recommending that we replace everything. He helped us determine what actually needed to be replaced and, just as importantly, identified improvements to the existing ductwork that could get substantially more conditioned air upstairs. We opened up and improved portions of the ducting as part of the project, and the difference has genuinely been a game-changer for the comfort of the second floor. What I've appreciated most across both projects is that Ali approaches HVAC like someone helping you solve a problem, not someone trying to maximize the invoice. He explains the tradeoffs, gives you options based on your priorities and budget, and then works to find the best solution and pricing within those preferences. When there are worthwhile improvements beyond simply replacing a furnace or AC unit, he'll point those out and explain why they matter rather than just adding things to a quote. After experiencing ARA's work on both a condo near South Coast Plaza and a townhouse in Fountain Valley, I would absolutely recommend Ali and ARA Heating & Air Conditioning to anyone looking for an honest, knowledgeable HVAC contractor in Orange County--whether you need an AC or heating system replacement, a more complicated installation, ductwork or airflow improvements, or simply someone you can trust to tell you what your home actually needs. It's rare to find a contractor you actively want to call again when you move into another house. Ali is one of those people.
