After receiving a 8 different estimates to replace one of my 5 ton 16 seer a/c unit and furnace, I made a decision to use A/C doctors to replace not one but both of my 5 ton units. All the other companies started their estimate off with a high price to replace the units, then when they saw that I had more estimates to meet with they began to drop their prices which is a red flag to me. AC doctors gave me their honest upfront lowest possible bid to replace one or both of my ac units without changing the price. They were on time and extremely professional. They explained everything to me upfront before I decided to use them. Eric and his crew did a marvelous job.I would definitely recommend them to anyone needing a/c replacements and repairs.
