Comfort in rooms the ducts missed.
Ductless mini-split installation, repair and maintenance across Northern Virginia.

A mini-split is an outdoor unit tied to one or more indoor heads by a small refrigerant line. There is no ductwork, so it fits where central air can't: a room addition, a finished basement, a bonus room over the garage, or an older house that never had ducts.
Each head has its own thermostat, so the bedroom can run cool while the office stays warm. The units run quietly and efficiently, and the filters in each head help clean the air. We install them, repair them and keep them maintained.
What the job includes
- Single-zone and multi-zone systems
- Wall-mounted heads and floor consoles
- Outdoor units on pads, brackets or rooftops
- Line sets run and covered neatly on the outside wall
- Repair of mini-splits other companies couldn't fix
- Cleaning and maintenance to keep them efficient
Signs it's time to call
- One room is always too hot or too cold
- You are finishing a basement, attic or addition
- Your home has radiators or baseboard heat and no ducts
- A space heater or window unit is doing the work now
- Your existing mini-split keeps having the same problem
What it costs
Cost depends on how many rooms, which heads and how far the line set runs, so we price it after a look. Every visit starts with a diagnostic fee, which covers finding the cause and walking you through what it will take. You get the price for the repair before we start, and nothing happens until you approve it.

From a customer
"I recently had a recurring issue crop up with one of my mini-splits that previous companies had failed to properly address. I told Ali my concerns with previous repair attempts, and he and his techs dug deeper and found the potential root cause, rather than just replacing parts."Ben Crosbie, Google review
