Level/Seer HVAC for 1800 sq ft townhouse?

[Daniel Felix]

We are going to be first time landlords in a couple of months for an 1,800 sq ft., 3 floor, townhouse condo. We need to replace the HVAC system, and I believe this is a "B property". 

1. What would you recommend for the SEER rating we get?

2. Any other recommendations?

Thanks!

@Daniel Felix it's hard for anyone to judge what size unit you need over the internet. Many things have to be taken into account. Current duct work size, age of home, current insulation etc. Higher the seer rating the more efficient the unit will be. Your best bet is measure each room and add up your actual square footage. A 3 ton unit is not too small for an 1800 sqft building again depending on insulation factors also age of windows. A 4 ton or 5 ton is a large unit for an 1800sqft structure. Bigger is not better in this case and don't let anyone tell u otherwise. Too many installers do not size units properly which cause issues down the road.
