Keep your mini-split quiet and efficient

Mini-splits are low-maintenance, not no-maintenance. Dirty indoor heads lose efficiency and start to smell; clogged condensate drains leak; and inverter boards can throw brand-specific fault codes that need real diagnostics to clear.

We clean the heads, flush the drains, verify refrigerant, and pull fault codes with manufacturer tools. On the Cape, salt air loads the outdoor coil, so seasonal cleaning matters more here than inland.

We service every major brand, not just the ones we install — and documented maintenance keeps your manufacturer warranty valid.
