AC problems

Ductless Mini Split Repair and Installation

For the room the central system never reaches, the garage, the workshop or the addition.

A ductless mini split is a small outdoor unit feeding one or more indoor heads through a refrigerant line, with no ducts at all. Around Houston they go into converted garages, workshops, sunrooms, additions built after the main system was sized, and the upstairs bedroom that is always five degrees warmer than the thermostat. They are efficient, quiet, and because they are inverter-driven they modulate rather than switching on and off.

They fail in their own ways. The indoor head's drain line clogs and drips down the wall. The filter in the head clogs and the unit ices. The outdoor unit's control board, which is more complex than a conventional condenser's, fails from a power surge. And refrigerant leaks at the flare fittings are the classic installation fault, which is why the installer matters as much as the brand.

For a new install the questions are whether one head or several, where the line set can run, where the condensate can drain, and whether the electrical panel has capacity. A contractor who installs them regularly will have those answers on the first visit.

What it looks like

Water dripping from the indoor head or down the wall
The head blowing but not cooling
An error code flashing on the unit
One room in the house that the main system cannot handle

Whatever the problem turns out to be, the first step is the same: describe it, say where the house is, and one independent HVAC contractor working in your town contacts you to look at it. No charge for being connected, and no obligation once he has.

Where

Ductless Mini Split Repair and Installation across north Houston

Humble

Subdivisions from the seventies to the nineties, so a lot of systems on their second or third replacement, with attic air handlers and original ductwork.

Kingwood

Big two-storey houses from the eighties under full tree cover, with upstairs that runs hot and air handlers in attics that reach 140.

Porter

Fast-growing Montgomery County, with builder-grade systems in the new subdivisions and older country houses on their original equipment.

New Caney

New construction along 59 beside acreage in the pines, with long power runs and surge damage after every storm.

Splendora

Rural lots, manufactured homes and older houses, where package units and window units are as common as central systems.

Crosby

East Harris County, older subdivisions near the lake, open land and salt air, which eats condenser coils faster than anywhere inland.

Dayton

Liberty County, country HVAC: heat pumps on propane-free properties, long drives for the technician, and nobody local to call.

The Woodlands

The biggest HVAC market north of Houston: large houses, often two or three systems each, and covenants on where an outdoor unit can sit.
