My heating system stopped working in last winter. I called one guy to do a repairing, he worked almost one house and tell me the system need to buy new parts to repair, the parts need about $2,200, and he have done the checking for one house, need to charge me $250. Since my house is just 3 years old, I don't believe my heat system need to order major parts, so I paid him $250 and let him go. Then I found Benson ( the owner of Ben Tech), he told me some parts did not connected properly and a bit dirty, so he used few minutes to done the work, the system back to good condition, but he only charged me $60. This guy is very honest and sincerely. Every since that, I use him to do all my rental property's air condition system, and also recommend to my friends.
