"Our AC went out yesterday evening and this morning at 7:30am my sister called an AC repairmen, Legacy Air Heating & Cooling, they answered the phone right away, made the appt for 10-12 today! Repairman showed up on time, fixed the clogged drain, checked the unit over, and told us a price, then finished fixing the problem, unit was low on freon, and then went into the attic to see if any ductwork was loose or off of the ceiling vents. Josh is a very professional serviceman. Best AC Repair experience I have ever had!"

"They were great. I hired them to remove old insulation and install new insulation. They discovered serious issues with my a/c duct work. They rearranged their schedule to come back and make repairs to the ducts. They were lifesavers."
