Mini Split Condenser Sizing Questions
I am looking to install mini splits throughout my entire home for air conditioning and supplemental heat for my steam boiler in fall/early spring. I have received quotes from multiple reputable Mitsubishi diamond installers but confused on the condenser sizing I’m being told I need. In total I am going to need 8 heads and his quote is split between two condensers that are 36k btu each (MXZ-4C36NA is the model) but the totals for the indoor units for each handler is 39k and 45k btus? Guy is assuring me this is ok? Said “I have a diversified load, so they'll never really ever be running at full power all at the same time? In summer I will definitely be running all of these at the same time.”
Any advice on if this sizing sounds right is appreciated. Want to be sure this is right before I move forward.
