Andover's historic homes and high-end additions made mini splits the go-to solution here — heating and cooling for spaces where ductwork was never an option. In Ballardvale antiques, Shawsheen Village colonials, and new bonus rooms alike, we repair the wall units, ceiling cassettes, and multi-zone systems other companies only install.
Mini split calls in Andover follow a pattern: blinking-light error codes, one head dead on a multi-zone system, water dripping from indoor units in summer, and outdoor units icing in winter. Long, concealed line-set runs in historic homes also make slow refrigerant leaks a recurring diagnosis.
A mini split with a failed board or a clogged drain doesn't need to be torn off the wall. We diagnose by manufacturer fault code, repair the actual failure, and price it upfront.
Blink patterns are manufacturer fault codes — they identify the failed component. We decode them and test the actual part rather than guessing.
Yes — most of our Andover mini split work is on systems installed by others, including installers who no longer service the area.
Almost always a clogged condensate drain or a failed condensate pump — a quick repair that prevents wall and ceiling damage if caught early.
Schedule service or call — same-day and next-day appointments available.
