How big of an air conditioner do i need for central air in 1100 square feet?
All these answers are the old way for sizing an house with the new changes in Energy Laws and eff. a sizing chart and ENERGY AUDIT need to be performed to ensure new unit will work properly. U have to many HVAC Contractors that will put the same size back in and not take the time to do this it may cost u some monry but in the long run it’s worth it trust me. If u don’t do this then you;ll be just another dissatisfied cust. with a brand new system.And this answer can be backed up by visiting your states energy program or calling local energy company and I’M a HVAC/Plum in trade 11 years so TRUST ME ON THIS AND GOODLUCK.
