Is a Multi-zone Ductless Unit Good for a Historic Home? - Ask the Expert Episode 137

It's next to impossible to update a historic home with new ductwork. That's why a multi-zone ductless system is a perfect heating and cooling option!

Video Script:

Rose wants to know: "How does a multi-zone ductless work for a historical home?" That's a good question. Most historical homes were built before the 1950's, which is really when they started building homes to accommodate central heating and air conditioning systems and ductwork.

A multi-zone ductless system is great for a historical home because you don't have to worry about air ducts. You can install the system and run the conduit lines and refrigerant lines through small spaces and put the air handlers wherever you need them.

    Multi Zone vs Single Zone I did 4 single zone mini split in my home. Will I save much more (electricity wise) compare to if I did a multi-zone system?

    That would depend on the relative efficiency (SEER) of the single-zone units compared to the multi-zone. The multi-zone wouldn't necessarily be more efficient than the single-zone systems based on the design alone.

    For example the multi zone was 20 seer but doing single zone is 30-33 seer on the units (Mitsubishi). What would be a good way to figure cost saving based on that.

    The exact cost savings are hard to estimate without knowing the size of the system(s) that would be required. However, overall efficiency of 30-33 SEER is going to be far better than 20 SEER, and could save on average around $100+ or more per year.
