Attic AC installation started by another contractor, sloppy awful workmanship, ceilings ruined, registers left unattached etc......asked them to leave. Hired another company to finish the install and start us up......paid alot of money to them to inspect and finish only to find out that not all work was completed....played telephone tag and listened to excuses for 2 weeks from them. Finally found Mersey, made us believers again that there may actually be someone in this industry with some integrity . Great service, spent lots of time explaining everything....will definitely use again
