The owner of this place is so unprofessional and doesn't show his employees any respect. It's no wonder he is always looking for help. Your employees are the backbone of a company and if you don't treat them with respect then your company will most definitely fail in time. And I hope he does fail because anyone who belittles his employees the way he does deserves to fail.

I cannot say enough good things about this company. Reasonable prices for my service agreement for my home, technicians are friendly and professional, plumbing is fast and respectful of my property. I would use them over any other HVAC or Plumbing company because of the service that I have experienced there.

One star because person driving company car nearly caused an accident. Tail gated us and several others on their way to the mall. Hopefully it wasn't an emergency that caused them to drive like that. Bad way to advertise for your company. But if that's any reflection of their company, I'd stay away. EDIT: It wasn't wanting to let me answer your response so hopefully you do see this, Unfortunately not much identifying info.

If I remember correctly it was a silver Kia, heading west on 22nd toward Parkplace mall. Just west of Kolb is where the driver caused a vehicle to swerve to avoid an accident. It occurred the same day I posted this, and I think it was late afternoon. Sorry I couldn't be more help.
