Well, A/C is 10 years old, they did an inspection and evaluation. The capacitor was in need of replacement and was probably costing us in higher electric bills. Also they installed a programmable thermostat for us. We were very pleased.

"My son needed assistance in getting his Cadillac through emissions. I went to a lot of places. They all wanted at least 3 times the value of the vehicle. I went on the DMV website and searched for mechanics with a 100 percent pass rate. I found Bryden's and found good reviews. Went in. Met a mechanic that was friendly. Explained everything and laid out the options and made it downright affordable. They did the repair and physically took it though emissions. Specifically track down an intake leak on a 2001 Cadillac Seville STS. Not an easy task. Job done. Very pleased with the service. I highly recommend them to not just do emissions but do other repairs."
