I was a loyal customer until last year. My rental property a/c unit stopped working and I called Campbell they came out after 2days put on a part, called me and told me my unit was working. I called the payment in over the phone. to find out minutes later, the unit was not working from my tenant. The worker did not even have time to leave the premises. They refunded me the money back for the part, they had on. which was not the problem, but charge me for putting it on. The owner would not return my calls. I was out of a large sum of money, since I was unable to get it back from my credit card. I definitely would not recommend them to anyone. You must be able to trust a company, and I didnt feel this way after this happen. read more
