Ductless, any brand
One room, its own mini-split
ACE is a Mitsubishi authorized installer and repairs ductless systems from any brand. Single-zone and multi-zone design for the rooms your main system never covered.
Chapter 01
Which room in your house never keeps up?
Ductless work starts with a room, not a machine. ACE puts the usual suspects in one line: “A converted garage, a sunroom, an upstairs bonus room, a primary suite at the end of a long duct run, a workshop or an addition that was never tied into the original system.” Each of them sits at the far end of the ductwork or was never on it at all.
A mini-split gives that room its own indoor head on the wall and its own outdoor unit, so the comfort of the space stops depending on a duct run that was never built for it. ACE designs single-zone systems for one room and multi-zone systems when several rooms each need their own.
The other failure is the one nobody schedules. A customer writing as PhenicieGolf Academy Golf Prof put it in one line: “Got same day service when my mini split went down!”

Who repairs a mini-split that somebody else installed?
ACE does. The crew on Cypress Church Rd is a Mitsubishi authorized installer and offers Mitsubishi authorized service, and ACE repairs ductless systems from any brand, so a head that was hung by another contractor is not turned away.
The same review shows how the visit runs: the technician arrived early in the projected window and diagnosis finished quickly. The reviewer's unit was several years old and still had parts under warranty, the parts took a few days to arrive, and the reviewer trusted ACE to repair it as soon as they landed. Diagnosis first, the price before any work begins, then the repair. Dee Guerrero described the same habit on another call: “Once identified he walked me through the problem and gave me reasonable options for a solution.”
New installations are single-zone or multi-zone design. If you are weighing a high-efficiency mini-split, ACE points customers to the CenterPoint Home Efficiency Rebates, which list high-efficiency mini-splits. That is CenterPoint's programme, so confirm its terms before you count on it.
Chapter 03
Maintenance past the filter rinse
ACE's own wording for mini-split maintenance is “beyond rinsing the filters”. The filter is the part an owner can reach. A visit from a technician is for everything behind it, on the indoor head and at the outdoor unit.
The Comfort Club is ACE's monthly maintenance plan, from $12.95 a month in a Silver tier and a Gold tier, with priority service on all calls and up to 20% off repairs. Ask on (281) 256-3433 how it fits the equipment in your house, and read the plans side by side on the Comfort Club page.
When a head stops responding at 2 a.m., the emergency line is answered around the clock. ACE is a Texas licensed HVAC contractor, TACLB 135382E, and has been working from Cypress since 2010.

Single-zone and multi-zone design
Where a duct never went
If one of these is your room, it is a ductless job. If three of them are, it is a multi-zone one. For whole-house cooling instead, see air conditioning, and for a heat pump that moves heat both ways, see heat pumps.
