Aire Serv of Southwest Connecticut: A nest of professional liars, led by owner head liar! Steer clear of them as they almost got me to replace my Heating & Air condition gas furnace. Thankfully there are honest HVAC contractors out there and after having hired two more Heating & Air conditioning contractors they both confirmed that the furnace Did Not need to be replaced. The system is still working in perfect condition. thanks to honest people out there weeding liars.
