I scheduled an appointment for a 'tuneup' between 3-5 on a Thursday thru SRP's program. Showed up late. Beware - This is just a paid estimate for a new AC unit. Do yourself a favor and call the dozens of other better rated companies for a free one. Tech wrote dirty coils, apparently a tune up doesn't involve wiping them down with a rag when you are standing next to it on the roof. Quoted me for a 4 ton unit on a 950 s/f house.
