Terrible experience from start to finish. I had two techs come to service my PTAC units. One did a…read moregreat job, the other didn't even bother cleaning the filters in my master bedroom. Immediately after the service, my 4-year-old PTAC started making noise and the thermostat stopped working properly. I called them back, and they sent a tech who insisted nothing was wrong--clearly to avoid holding the first tech accountable. I then hired another company, who found a leak and confirmed the unit was losing freon. When I confronted YuHan, she claimed it was "impossible" their first technician caused the problem and that their company "never makes mistakes." That's hard to believe when they couldn't even clean a filter. She asked me to send pictures and receipts, but it's pointless--she'll just deny responsibility no matter the evidence. She basically said I am lying. I attached a picture, this was AFTER the "cleaning". You can see the line thats leaking. The rep went as far as saying I am taking pictures of a third unit they never serviced, as if I am trying to scam them for a machine that wasn't working. Its ridiculous There are far better companies out there, and I can recommend a few. My advice: stay far away from these guys.

They work site was kept organized and everything was clean and disposed without issues. And same with Fatima and Nicole last time, working with Marylyn on payment and schedules and follow-ups are always a pleasant experience. Thank you again. I have referred you on NextDoor and I wish Shadi nothing but the best. 11/2020 Just had my 30+ year old heating furnace replaced by Shadi's team. Everyone in the group was a pleasure to work with. From initial visit by Paul, to installation by Fernando, and follow-up by Ahmad, the experience was above and beyond. The work is completed in a day and work site is cleaned up nicely afterwards. Lastly, reaching out to Fatima and Nicole for questions and follows up are always met with courtesy and promptness. Thank you Shadi for a great team and for the wonderful service.

According to my father: Dad called around for an urgent…read moreplumbing issue, at around 11pm, which caused clogging in the toilet and backflow up the shower drain. This was the only Korean plumber who had an answering machine in the area. Dad speaks both Korean and English. After leaving a voicemail late at night about an urgent plumbing issue, my dad got a call from the plumber's wife at around 5:30am in the morning. I mean that is a really fast response time. Turns out, most of the clog was fixed (drain cleaner poured in the night before) by the time the plumber arrived. The plumber took the time to explain the problem (clog was not where originally thought) and charged a very reasonable fee for the early morning visit over (less than the $150 or hourly fee other plumbers in the neighborhood were quoting for the same type of work). Everything was resolved by 7am, but the peace of mind of knowing there's a dedicated plumber in the area was a great relief to my dad. Plumber is an elderly gentleman, been working as a plumber for decades, and very easy to talk to (well, as far as I know, in Korean).
