Very disappointing service. Had a tenant living here who ran everything. Miller came 5 times total to fix my a/c system. They filled the system everytime and it lasted no more than a month. Finally they decided to find the leak and then ""repaired"" it. Freon continued to leak out, went into the summer heat without A/C. When I called them, they claimed to guarantee their work, but wouldn't send a tech out to fix my system that they supposedly already fixed. I made an appointment to have someone come take a look. First day they did not arrive in the specified time so I rescheduled for the next day. That day he came, but looked over the invoiced from before and claimed a bunch of b.s. for how he fixed the leak and ""you must have a new leak."" Or they didn't fix the leak in the first place. I highly recommend anyone thinking of this business to go find a homeless guy and give him $1000. You'll have the same results, but at least this way you'll improve someone's life. If i could, I'd give them 0 stars.
Cons: slow, dishonest, shoddy work
