Mitsubishi: common questions

Does Mitsubishi cost more than a ducted system for the same coverage?

Per zone, yes, ductless multi-zone usually carries a higher equipment cost than extending ducted air, and concealed-duct heads add labor on top. The payback is no demolition and independent control per room. New Mitsubishi installs carry our 10-year parts warranty, with labor at 2 years standard (10 years on our maintenance plan); repairs carry one year.

What does the warranty cover on a Mitsubishi install?

A new Mitsubishi install carries our 10-year parts and 10-year labor (2 yr standard, 10 yr with our maintenance plan) warranty, with Mitsubishi's own parts coverage through their registration program when we do the install. Repairs on an existing unit carry a one-year warranty. The $99 diagnostic fee is credited toward the repair.

Should I just seal my old ducts instead of going ductless?

Often yes. If the ducts test reasonably and the runs are intact, sealing is the cheaper path and we'll recommend it. Mitsubishi ductless wins when leakage is high enough that a retrofit costs about as much as a mini-split, or when a room has no duct service at all. We put both numbers on the estimate.

My AC is old, repair or replace, and where does Mitsubishi fit?

If the central system is failing, we run a Manual J and quote a properly sized ducted replacement rather than reaching for ductless by default. R-22 systems with refrigerant leaks usually pencil toward replacement. Mitsubishi fits the targeted rooms, not the whole-house load. New installs carry 10-year parts, with labor at 2 years standard (10 years on our maintenance plan); repairs one year.
