Replace a Failing Mini Split in Austin

Updated September 2026 · ATX Mini Split King, Austin and Central Texas

Homeowners in Austin and Central Texas often look for a replacement when their existing Haier ductless unit stops keeping up. Long hot summers put a load on older systems in additions, converted garages, and houses without full ductwork. ATX Mini Split King is an independent HVAC and electrical contractor. We remove the old equipment and install a new ductless system to code. Call (512) 297-7493 to talk through the job.

ATX Mini Split King is an independent HVAC and electrical contractor. We are not affiliated with, endorsed by, or a representative of Haier or any manufacturer. The Haier name appears here only to describe equipment that may already be installed in your home and that we can remove and replace. All manufacturer names are the property of their owners.

Flat pricing, everything included

Those are materials and labor together, wired to code by a TDLR licensed contractor. Anything non standard gets quoted first, before a single tool comes out of the truck: a very long line set, an electrical panel that needs work, a difficult mount, a roof or masonry penetration, disposal of the old equipment. You hear the number before we start, not after.

What usually brings a homeowner to this page

A homeowner usually lands on this page because the indoor head is not cooling the room the way it used to. In Central Texas the summers run long and hot, so a space that used to feel comfortable in July now stays warm even when the unit runs for hours. Sometimes the compressor outside cycles on and off in short bursts instead of settling into a steady run. That pattern is called short cycling. It can come from a refrigerant issue, a sensor, or simply age. The sound may also have changed. A unit that once ran quietly now rattles, hums, or clicks in a way that is hard to ignore, especially at night in an addition or a converted garage.

Age is another common reason. Many ductless systems in older Austin houses, garage conversions, and room additions have been in place for years. Parts wear. Filters clog if they are not cleaned. Outdoor coils collect dust and pollen. A repair quote that comes back high is often the last straw. When the cost of a compressor, a board, or a leak repair approaches the price of a full replacement, people start shopping. ATX Mini Split King sees this pattern often. We do not sell the existing Haier equipment and we have no relationship with that manufacturer. We simply remove what is there and put in a new system if that is the better path.

Winters here are short and mild, so heating performance is less of a daily issue than cooling. Still, if the unit struggles in both seasons, or if the homeowner is already planning other work on an addition, replacement can make sense. The symptoms themselves do not tell you the brand is at fault. They tell you the equipment in that location is no longer doing the job the house needs. A TDLR licensed contractor can look at the installation, the electrical, and the remaining life of the parts and give a straight answer. That is the starting point, not a sales pitch.

Repair versus replace, an honest look

Repair is often the smarter money when the problem is simple and the rest of the system is in good shape. A dirty coil, a failed capacitor, a clogged condensate drain, or a control board that is still available can be fixed without pulling the whole setup. If the outdoor unit and indoor head are only a few years old, the line set is sound, and the electrical is already correctly sized, paying for a targeted repair keeps the existing Haier equipment in place. ATX Mini Split King will say so. We are an independent contractor. We do not have a reason to push replacement on a unit that still has useful life. In Central Texas a well maintained ductless system can keep an addition or garage conversion comfortable through another stretch of hot summers. The decision turns on the actual condition, not on a calendar.

Replacement starts to make sense when multiple parts are failing at once, when the indoor head is in the wrong place for how the room is used now, or when the electrical and line set would need major work anyway. Older housing in Austin often has undersized circuits or a disconnect that no longer meets code. A converted garage may have a wall penetration that is poorly sealed or a condensate route that dumps water where it should not. If a repair quote is already high and those other items would still need attention, a full swap can be cleaner. We quote the replacement as a complete job so there are no surprises after the old unit is gone. Honesty here means we will also tell you when a mini split is the wrong answer, for example if the house already has working ducts.

Cost is not the only factor. Time without cooling during a Texas summer matters. If a repair part has a long lead time, replacement with equipment that is on the truck can restore comfort the same day. Conversely, if the existing Haier unit still cools most of the time and the noise is livable, waiting through one more season while you plan other home work is reasonable. We do not invent urgency. A site visit lets us see the pad, the bracket, the penetration, and the circuit and then talk through both paths in plain language. That visit is how we decide together whether keeping the current setup or starting over is the better use of money.

What carries over and what does not

Some pieces of the old installation can stay. The outdoor pad is often reusable if it is level, large enough, and not cracked. We check that the new condenser sits stably and that airflow around it is not blocked by fences or plants that have grown in. The wall penetration, the hole through brick, siding, or the garage wall, can frequently be reused if it is the right diameter and height. We sleeve it and seal it again so rain and insects stay out. In older Austin houses the original hole may be too high or too low for a better head placement, in which case we patch the old opening and cut a new one.

The line set, the copper pipes that carry refrigerant between indoor and outdoor, is the item most often replaced. Flare connections age. Insulation on the suction line cracks in the sun. Oil residue and the old refrigerant type may not match the new equipment. We recover the old charge, cut out the lines, and run new insulated copper with proper traps and supports. Reusing a line set is possible only when it is the correct size, in good condition, and we can verify it is clean and dry. That judgment happens on site, not from a photo. The disconnect and the circuit are electrical items. If the breaker, wire gauge, and disconnect already meet code for the new condenser, they stay. If the run is undersized or the disconnect is rusty and fused, we pull a new circuit as part of the electrical work we are licensed to do.

The mounting bracket for the indoor head is usually replaced. New heads have different mounting patterns and weights. We install a level bracket into studs or use proper anchors in masonry. The condensate route, the drain from the indoor coil, is checked for slope and discharge point. Gravity drains that already fall to a proper location can stay. Pumps that have failed or lines that dump onto a sidewalk or into a wall cavity get rerouted. In a converted garage the drain often needs a new path to the exterior or to a laundry sink. All of this is inspected before we commit to reusing anything. What we cannot reuse we replace so the new system starts with clean, code compliant connections.

What replacement day looks like start to finish

Before anyone shows up with tools, the homeowner decides three things. First, where each indoor head will sit. Height, distance from corners, and airflow across the room all matter. In an addition the original location may have been chosen for convenience rather than comfort. Second, how many zones the new system will serve. One head for one room is simple. Two or three heads let you condition an addition plus a garage conversion or a sunroom without tying them to the main house ducts. Third, where the outdoor condenser will sit. Clearance from walls, windows, and neighbors, plus a path for the line set that is as short and protected as possible, drives that choice. We walk the site with you so those decisions are made with the actual walls and yard in view.

On the day itself we start by isolating power, recovering refrigerant from the existing Haier unit, and unbolting the indoor head and outdoor condenser. The old equipment leaves the property. If the pad, penetration, and circuit are staying, we protect them while we work. New line set is run, brazed or flared as the equipment requires, insulated, and pressure tested. The new indoor heads go on their brackets, level, with the condensate pitched correctly. The outdoor unit is set, leveled, and connected. We pull vacuum, charge, and start the system. Electrical connections at the disconnect and the heads are made up to code. We run each zone, check temperatures, and show you how the controls work. Cleanup includes hauling away the old unit and leaving the work area swept.

A typical one or two head job finishes in a single day if the decisions were made ahead of time and the existing path is usable. Three heads or a difficult line set route, such as through a finished attic or around a masonry chimney, can push into a second day. Weather in Central Texas can also slow outdoor work. We do not leave the house without cooling if we can help it. If something unexpected appears, a rotten stud behind the old bracket, a circuit that will not pass inspection, we stop and quote the extra work before we proceed. You are not on the hook for surprises after the fact.

Flat pricing and what gets quoted separately

ATX Mini Split King prices a standard replacement at $1,500 for one indoor head, $2,500 for two indoor heads, and $3,500 for three indoor heads. Those figures include the new indoor and outdoor equipment, new line set, labor to remove the existing Haier unit, electrical connections at the existing disconnect, mounting, condensate, startup, and haul away. The work is done to code by a TDLR licensed contractor. The price assumes the outdoor pad, wall penetration, and circuit can be reused or need only minor adjustment. It assumes a straightforward line set path of typical length on a single story or an accessible second story. Central Texas jobs in older houses and garage conversions often fit this description. We confirm the assumptions on the site visit so you know the number before we schedule.

Anything non standard is quoted separately before any work starts. A new circuit from the panel, a new disconnect, a pump for condensate when gravity will not work, extra line set length, a second story with no attic access, masonry that needs a core drill, or moving the condenser to a different pad all fall outside the flat figures. We write those extras down, with a price, and wait for your go ahead. We do not start the job and then add costs. If the existing equipment can stay with a repair, we quote that repair instead. The goal is a number you can plan around, not a low starting price that grows. Call (512) 297-7493 to set up the visit that produces the quote.

Payment is due when the job is complete and the system is running. We do not take a large deposit before we arrive. Permits, if the city or county requires them for the electrical or the mechanical change, are handled as part of the quoted extras when they apply. Austin and surrounding Central Texas jurisdictions vary. We tell you what is required for your address. The flat prices cover a complete, working replacement of a failing unit with a new ductless system of matching zone count. They do not cover unrelated electrical upgrades or structural repairs we might notice while we are there. Those would be a separate conversation.

What to ask any installer, and when to keep the old unit

Before you hire anyone, ask whether they are a TDLR licensed HVAC and electrical contractor, not just a helper with a truck. Ask how they will recover the old refrigerant and dispose of the existing Haier equipment. Ask whether the quote includes a new line set or assumes reuse, and what happens if the old copper fails a pressure test. Ask who pulls the permit if one is needed. Ask how they will protect floors and walls in an occupied house. Ask what the homeowner must decide before the crew arrives, head location, zone count, condenser placement. Vague answers are a reason to keep looking. ATX Mini Split King is independent. We have no affiliation with the manufacturer of the unit we are taking out.

Keeping the existing equipment is the better decision when a single inexpensive part will restore function, when the indoor head is already in the right place, and when the electrical and drainage are already correct. It is also better when the space itself is a poor candidate for ductless. A whole house that already has ducts may be served more simply by repairing or replacing the central system. A tiny closet or a room with no exterior wall for a line set may not be worth a mini split. We will say that. Long hot summers make cooling important, but they do not make every room a mini split job. Short mild winters mean heating is secondary here, so a unit that still cools well can be left alone even if heat is weak.

If you are unsure, the cheapest next step is a site visit. We look at the failing unit, the pad, the penetration, the circuit, and how the rooms are used. Then we give you the repair path and the replacement path with the flat prices or a custom quote. You decide. ATX Mini Split King works in Austin and Central Texas on older housing, additions, and converted garages. Call (512) 297-7493. We will not claim a relationship we do not have with any manufacturer. We will not tell you a mini split is the answer when it is not. That is the honest way to handle a unit that is not cooling, is short cycling, is loud, or has drawn a high repair quote.

Questions people actually ask

Can you reuse my existing line set when you replace the unit?

Sometimes. We inspect the copper for size, condition, and cleanliness. Flare nuts and insulation often fail first. If the line set is the right diameter, holds a pressure test, and can be flushed, we may keep it. In most replacements we run new insulated copper because the old refrigerant and oil may not be compatible and because sun damaged insulation is common on outdoor runs in Central Texas. The decision is made on site. Reuse, when it is sound, can reduce the work. When it is not, new lines are part of the flat price for a standard job.

What if my outdoor pad is cracked or too small?

Then it is quoted as extra work before we start. A cracked pad can be replaced or a new composite pad set. If the condenser needs to move for clearance or noise, we quote the new location, the extra line set, and any electrical extension. Standard pricing assumes the existing pad is usable. We will not set a new unit on an unsafe base. In older Austin lots the pad is sometimes against a fence that now violates clearance. Moving it is common and is priced up front so you can choose.

Is a mini split the right choice for every room in an older house?

No. If the house already has a working ducted system, extending a run or repairing the central unit is often simpler and cheaper. A room with no exterior wall, or a space so small that a head would blow directly on a bed, is a poor fit. Converted garages and additions without ducts are the usual good candidates in Central Texas. We will tell you when ductless is the wrong answer. Keeping the existing Haier unit with a repair is also better when the symptoms are minor and the rest of the installation is sound.

How long will I be without cooling?

On a standard one or two head replacement we aim to have the new system running the same day we remove the old one. We recover refrigerant, swap equipment, pull vacuum, and start up before we leave. Three heads or a hard line set route can take a second day. We schedule so the house is not left open during the hottest part of a Central Texas summer if we can avoid it. If parts or weather delay us, we say so before we start. You will know the plan when we book the work.

Do you have any relationship with the maker of my current unit?

No. ATX Mini Split King is an independent HVAC and electrical contractor. We have no training, approval, affiliation, or endorsement from the manufacturer of the existing Haier equipment. We name that brand only because it is the unit already on your wall that we may remove. We do not comment on how that equipment performs compared with others. We look at the actual installation in your house, the symptoms you describe, and the cost of repair versus a new ductless system. Call (512) 297-7493 for a site visit in Austin or Central Texas.
