LEARN MORESan Marco was first developed in the late 1920s, and many homes here were built long before central air was common. That often means no ductwork in some rooms, ducts squeezed into tight attics, or additions that never cool down properly.
We help with ductless mini-splits that add cooling without opening walls, duct inspections and sealing to stop cooled air from leaking into the attic, and correctly sized systems that pull moisture out of the air. Being close to the St. Johns River means humidity is part of daily life, so we size every system to dehumidify, not just to cool.

Yes. A ductless mini-split heat pump cools and heats without ducts. An outdoor unit connects to slim indoor units through a small opening in the wall, so there is no need to open up walls or ceilings, and each room gets its own temperature control. It is a popular choice for older homes, additions, sunrooms and converted garages.
Common causes are a system that is too large and shuts off before it removes moisture, a dirty filter or evaporator coil, the thermostat fan set to ON instead of AUTO, or leaky ducts pulling in humid attic air. The EPA recommends keeping indoor humidity below 60%, ideally between 30% and 50%. A tune-up, duct sealing or a whole-home dehumidifier usually solves it.
Our standard residential diagnostic fee is $89, and you get a flat-rate price before any repair begins. Most common AC repairs in Jacksonville cost between $150 and $1,800, depending on the part. Our AC repair cost guide explains the typical prices part by part.
At least once a year, ideally in the spring before the summer heat. If you have a heat pump, which heats and cools all year, schedule two visits: one in the spring for cooling and one in the fall for heating.
A useful rule of thumb is the $5,000 rule: multiply the age of the system by the repair cost. If the result is more than $5,000, replacement is usually the smarter choice. Systems older than 12 to 15 years, or that still use R-22 refrigerant, are also good candidates for an upgrade. We provide free estimates for new systems.
