Takes about a minute. No obligation.
A mini-split compressor starts and stops hundreds of times across a cooling season, and the contactor that triggers each cycle absorbs the damage. Homes in Clark County, NV run cooling about five months a year, from May through September. By the time a homeowner notices reduced output or a unit that runs but won't cool, the contactor, the capacitor, and the refrigerant circuit have all logged hard use. A contractor diagnosing a mini-split here checks those components before looking anywhere else, because that is where the load lands.
The wiring run to a wall where a mini-split now sits tells a contractor more than the unit itself does. Half the homes in Clark County, Nevada were built in 1998 or earlier (2020-2024 ACS 5-year). That means a share of the county's homes were built around cooling equipment that drew power and moved refrigerant differently than what runs in them now, and the electrical feed to the indoor head reflects those original decisions. A contractor opening a mini-split for repair checks what that feed actually delivers before concluding the unit is the problem, because an undersupplied head fails in ways that look like a refrigerant fault or a board fault until the supply is measured.
The Parts of a Mini-split a Contractor Checks First
The indoor air handler mounts high on an interior wall and pushes conditioned air directly into the room. Its blower wheel, evaporator coil, and drainage line are the first places a contractor looks when cooling or heating has weakened, when water is dripping where it should not be, or when the unit is running but doing nothing useful.
The outdoor compressor unit sits on a pad or bracket outside the house and carries the compressor, condenser coil, and fan. The refrigerant lines and the control wiring run between the two units through a small opening in the wall, and a fault anywhere along that path shows up as a symptom inside.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines which parts apply and what condition they are in for your specific home.
