Nest thermostat

[fishinpox]

first off i know for a fact nearly every a/c contractor over tons new houses. for that reason i had my system for my new home designed by a engineer who specalizes in hvac. we are going slightly under ton from what ar****ect/ havc contractor said to do . i will be using variable spped furance and a 2 stage condenser unit with a 16 seer rating . this way we will be able to remove more humidity from my home by slowing down the fan but having it run more often due to under tonnage . i also am having them install a PCO air cleaner on both units, my hvac contractor told me htis air cleaner works so good that if you light a perfumed candle in your home while the system is running you will not smell it ! my goal is to be able to tweek my system and fine tune it to make it as efficent and comfortable as possible
