New A/C for Houston area 2.5 ton
We have a 2600 sq ft home in houston. The A/C and furnace are 15 years old. We have two units in the home, down stairs outside unit was relaced before we moved in. The upstairs unit leaks freon and needs a charage every spring. This year it seens to run all the time even with the new charge.
I cleaned outside coils and inside evap. coils and changed out the thermostat to a honeywell 8000. Also may return filter is only 12"x36", not sure if this is large enough for our unit?
It is a Trane XE1000 TTR030C100A2, is this unit a 2.5 ton?
Also what should I expect to pay for a new unit, and should we replace the furnace also?
Also, the down stairs unit does leak a small amount of freon as well which I am thinking from the upstaris coils.
