We called TAM for an A/C tune up before summer sat in with the bad heat. We had several bad experiences with other A/C companies and was very apprehensive in calling anyone but had to weigh the bad on both sides and we were not interested in being without air 1 day. So, I called and Oscar scheduled an appointment and came out as planned. He reviewed the unit, upstairs and out and came up with a plan. He explained the only warranty would be what he did and if we did not have warranty on the compressor there was nothing they he could do, one of those warranty companies had installed the current unit and we could find no warranty being registered. So, we asked Oscar to work up a price for a new unit as well as new duct work as last year the company messed up everything and we were paying for our attic to be cooled. We were quite concerned what this price was going to be as we are both retired. Wow what an amazement to both of us! It was a very reasonable price and a guarantee we could not pass up, like lifetime! The following week end TAM and the whole crew were here and now 2 weeks later we are sitting in a very comfortable house. Oscar took care of our humidity issue, unit running non stop, and a consistent cooooool! We recommend and trust all that TAM and Oscar recommend!
