Greg was great!!!- We had another outfit do an estimate last week at 17,000 dollars as ac and furnace shot and even if we had just ac fixed over 3500 dollars - that guy was condescending and wore a white shirt and expensive shoes and did not appear he had any intention of doing any repair-Then Day and night Greg came and he was fantastic!!! We will never call anyone but day and night for their service and honest business practices- less than 300 dollar repair as opposed to 17,000 dollars-you are the absolute best!!!!!!!!!!!!!
