Mr. Kim is the most hardest and dedicated worker I have ever met. He works efficiently and gives the best deals. I got an air conditioning unit that was $4000 for $3450! I really recommend 777 Mechanical. It's small business so they care to your needs. It isn't some big corporate mammoth that just wants money. Mr. Kim will take care of your air conditioning and heating needs as if he was taking care of his family's.
