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 really wanted to have a positive experience with this HVAC company, but unfortunately, it didn't…read moreturn out that way. 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.

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?

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.

Abdul picked up quickly and was so accommodating to fit me in after 5pm. He was able to locate the issue and fix it in timely manner at a reasonable cost too. 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. I would give the biz 3.5 stars but yelp doesn't have that option.
