Our AC went out a little over a week ago, of course it happened toward the end of the week so it…read morewas Friday afternoon by the time we realized it wasn't something routine maintenance on our side would fix. Jary (who helped us when we first moved in) came out on Tuesday and said we had a leak somewhere since the closed-system unit was totally out of coolant. He came back Weds. to do the leak detection and found the leak, recommended a new coil. We had the new coil installed on Friday; this time it was Ricardo and team that did the work installing the coil. They did a great job and a couple hours later our house was back to normal temperature. Gabriel helped us with all the coordination and estimates and seeing if the part was still under warranty (it wasn't, but I didn't expect it would be honestly.) No one likes spending a bunch of money on repairs but I'm very confident that the recommendations Jary made were sound and correct. He did not attempt to upsell me at all, which is greatly appreciated. (The estimates Gabriel sent did include options for replacing the unit, but that wasn't necessary at this time and there was no pressure to do so.) I will continue to call them if we have issues in future with our HVAC system.

I originally complained about response times, but thank you Gabriel for the explanation, I'll reach…read moreback out after the summer.

Let's talk about how my water heater started leaking during one of winter's last cold spells LOL!!!…read moreTo stop the leakage, I had to turn it off... which means I didn't have any hot water, yikes! Thankfully the mess didn't get out of control -- but waiting on the claims process from my warranty was a bit of a pain and back and forth, no doubt. After dealing with them, I learned I had to replace my unit... and thankfully, while it was free, I had to pay for installation, which was going to be quite hefty through them. Thankfully, my dad had just gotten some related work done, and asked the guy about it. And a few days later, Mohamed was able to come out to my house and take care of everything for a much better price than what was being suggested through my warranty! He also noticed two small leaks in the pipes around my water heater and fixed them without charging too much extra. It's been a few weeks now, and everything is still working wonderfully. He was very professional and polite, and I would recommend him for other jobs in his skillset. Can my hot water go down in the summer next time?

Unfortunately, the system…read moreis not working properly this year, and I have had a very difficult time getting any response from the company. I have tried reaching out multiple ways, including email, Yelp message, phone call, voicemail, and text message, but have not received a response. I understand companies get busy, but when a recently installed HVAC system has an issue, I would expect some level of follow-up, especially if warranty service may be involved. Based on my experience, I am disappointed with the lack of communication after the installation. The initial work may have been completed, but the lack of response when a problem came up has made it difficult to recommend them.

He also provided what next steps would be for a more permanent solution. It was a very professional, friendly service call.

I contacted this company due to my AC breaking down. They cancelled and rescheduled an appointment…read moreof which they put me out until Friday and said someone would arrive at 7 AM. At 8 AM. I called them and the dispatcher Heather refused to talk to me and made the other person tell me that their truck broke down and that they could possibly get me on the schedule today. Don't use these people if you actually want service fulfilled and especially if your furnace or AC has broken down. Response to Alex: your dispatcher Heather would not take my phone call and handed it over to Tyler who told me that your truck broke down. Tyler also said he may be able to get me on today's schedule. How much do you think that was going to happen? I had been rescheduled initially due to double booking the first go round and then suddenly your truck breaks down. This whole process started on Tuesday when my condenser was not working. With the upcoming weekend having extreme heat, I needed it to work. And this must be part of your problem because if you don't think making an appointment and keeping an appointment is part of your service then that is a huge issue.

When I asked what I thought were straightforward questions about the PSI readings before and after Freon was added, the technician became noticeably defensive and agitated. I ended up having to stop the conversation and asked him to just complete the work, which made things feel tense and unprofessional. To his credit, he did apologize later and his tone became more friendly, but by then, the interaction had already left a bad impression. I had no problem paying the $800 freon recharge cost, but at that price point, I think it's fair to expect respectful communication and transparency. I was simply trying to keep track of the PSI readings for my own records, since I'm dealing with a known leak. As a customer, I believe it's reasonable to ask questions and feel comfortable doing so. Unfortunately, based on this experience, I won't be using their services again and can't recommend them.

Update: Aug 7 2025 -- Abdul had to come back and check the unit bc it was definitely working overtime and still doesn't feel cool. It might be the unit but he added what he could and cleaned up what he thinks could be the problem. I did look back on the bill he gave me the first visit and checked to see what I got charged. Everything seemed legit except that he charged me $120 for travel cost, which was a sticker shock to me. I would think most hvac folks gave to travel to homes in order to provide service, so I see that as cost of doing business, but that's just me.
