Called them, my first a/c call because i had coupon...a/c was working ok, but didnt want to wake up a 3 am w/ no a/c. Scheduler gave me a run down of different price points depending if i wanted 1, 2 or 4 hours windows. Chose the 4 hour window, the cheapest..99.00....I asked if the technicians are paid a commission on what they sell. She seem rather insulted that I asked...long story short I had a bad feeling after I made the appointment....checked yelp, angies list....Comments/write ups were not very encourging...any rate found another company I was very satisfied with and gave me a much lower charge to check my a/c.
