Well what can I say these guys are horrible. They sent 3 guys out to come paint the house, they did their job and left a horrible mess. 1. I caught these guys stiffing their Panda Express lunch boxes and Dorito bags in my bush, mind you I caught this on my ring camera. 2 left a ton of over spray in my back fence 3. Used my garden hose and didn’t bother to put it back, left it laying across my yard 4. These guys decided to wash buckets of paint on the side of my house and leave paint in the rocks 5. They left my yard rock spread across my drive way as well. One of workers was acting really immature, singing loudly near the window around 6 am and I also have a video of him laying out on the patio and then screaming for whatever reason. Just really obnoxious. I had reached out to the company concerning the issues, I spoke with a man named Eddie which he was pretty professional, claims to be the owner. He told me that somebody would be out the next day first thing in the morning to take care of all of the issues that I had. I also sent him videos that I captured on my ring camera and all these pictures I’m posting here. The following day happens and he did not show up at all. I told him that I was going to be writing a bad review about it and he told me “if it makes me feel better then go ahead”. This man did not keep his word, and this is coming from the owner of the company. If you can’t trust the owners word, how can you trust a company at all? I would stay far away from this place do not waste your time or your money. Unless you like unprofessional workers and poor work quality. I really wish Google would let me add videos, then everybody would be able to see how ridiculous they are.

I was literally yelled at by Mike who claims to be the owner, over because I called multiple times and got no answer. I was just trying to make sure I was home so i don’t miss the repair schedule & technicians arrival. He answered the phone after the 3rd or 4th time I called and literally greeted me with yelling at the top of his lungs “Where do you get off calling multiple times like that!? Can’t you understand we are busy and you don’t know how to leave a voicemail?” He literally went off on me with more rude words and I was literally beside myself.. I’ve NEVER in my life have been treated & disrespected by any service company ever until this afternoon. I filed an incident claim with my rental company and emailed the incident and sent screen shots and an audio file of a portion of him yelling at me which I recorded using my friends phone. I’m beside myself! How dare you speak to customers like that. NEGATIVE Stars rating if I could I’d give them -100 stars like THE WORST CUSTOMER SERVICE EXPERIENCE AND TREATMENT EVER.

Do NOT use. The company is sloppy and ruined my roof. Even worse, due to their work on my roof he VOIDED my roof warranty! When I brought this issue up to them, they claimed I told them they could cut my roof. Which doesn’t make sense because now I have to pay 5,000 to get my roof fixed AND with no warranty DUE to this company.

Huge should out to Eddie Mosso with Tri State Mechanical. From beginning to end, this was an excellent experience. He just installed 2 new AC units and 2 smart thermostats at my house as well as at my parents house. He was very reliable, punctual, and professional. Summer is here and the temps are going up so make sure to give him a call for all your HVAC needs.
