I have a new Model 6 Mattamy.... 1750sq.
I've been told a by 2 different people that a 2ton is prefect for the home, and another 1 one person that a 2.5 ton is perfect for my home.
With a smaller home is there a real benefit to going to a 2.5 ton unit?
Thanks for your question Wyl,
It is recommended that we perform an on site inspection to determine appropriate sizing however we have installed AC units in many Mattamy plan 6 homes. I agree the correct sizing of your AC unit should be a 24,000 btu or 2 ton even with 9ft upgraded ceilings on the 2nd level and south exposure. Im not sure why a HVAC contractor would suggest a 2.5 ton AC for your home as this will be oversized and cause short cycling. Short cycling is when an AC has been oversized for your home. The negative effect is that the AC will turn on satisfying setpoint prematurely causing poor air flow in your home, particularly on the 2nd level.
This is why it is important to do your research when finding a qualified, reputable company for your HVAC needs. Unfortunately there are many fly by night companies that offer you an unbelievable price for your AC unit but fail to draw ESA permits, dont assume your furnace warranty and disappear once you have a furnace or AC issue.
