I searched and see many upsize the coil to gain a bit of seer, but want to make sure our contractor recommendations are ok.
We have a second lake home just outside of Dallas. It 1750 sq ft. quite a few windows. We are only there for weekends and some long weekends for the summer. Dont want to dump a ton of money in it, but do want system to works correctly. We will keep the home another 5 years or so.
Contractor (does a lot of work for subdivision) and lives in our subdivision says that 4 ton unit is big enough to cool home the way it is set up. He said coil is only appx. 5-6 yrs old and is fine. Its Carrier ce3axa06q000abaa.
He suggested a Payne 13 seer 4 ton unit. He said we would gain a little efficiency paired with the 5 ton coil.
Not sure what else I should be asking. He said payne is a good unit for the money and for our limited use and we should get many years of good service out of it.
This all sound ok? Anything I should be leary of or questions I should ask.
Thanks in advance for your help!
