The usual suspects
Filters you can wash — but nobody does
Mini split filters clog in months, and output drops long before failure. The five-minute fix owners forget exists.
A refrigerant leak
Flare fittings at the line connections are the classic slow-leak spot — gradual decline over a season.
Mode conflicts on multi-zone systems
One head asking for COOL while another asks HEAT — somebody loses. Multi-zone systems have one outdoor mode.
Sensor or board faults
A unit that misreads room temperature satisfies instantly and idles — blinking-light codes usually say so.
Mini splits are a specialty here.
We install and service ductless daily — Mitsubishi, Daikin and the rest. Price approved before any work.

Quick answers
Why did it slowly get worse over the summer?
Gradual decline is the leak-or-filter signature — both throttle output progressively. Wash the filters first; if that doesn’t restore it, the gauges will find the rest.
One room works, the other doesn’t. Why?
On multi-zone systems, check for a mode conflict first — then per-head issues like filters or a failed board. Zone-by-zone testing sorts it quickly.
