ATX Mini Split King is an independent HVAC and electrical contractor. We are not affiliated with, endorsed by, or a representative of Midea or any manufacturer. The Midea 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.

Why an existing unit brings homeowners to this page

The most common reason a homeowner in Austin or the surrounding Central Texas area lands on a page like this is that the existing Midea unit is not cooling. During the long hot summers the indoor head may send out air that feels barely cooler than room temperature. In an older house, an addition, or a converted garage the problem shows up as one zone that never quite reaches a comfortable temperature while the rest of the home feels fine. Short cycling is another frequent complaint. The outdoor unit starts, runs for a few minutes, then shuts off, then starts again. The pattern can go on all afternoon. Loud operation is also typical of equipment that has been in service for many years. The indoor fan may rattle or the outdoor unit may hum or vibrate more than it used to.

A high repair quote is often the last straw. A technician looks at the existing Midea equipment, names a price to fix a compressor, a board, a leak, or a fan motor, and the homeowner compares that number to the age of the unit and the remaining summers it might last. In Central Texas the cooling season is long, so a repair that only buys one more summer can feel like poor value. The quote itself does not tell you whether the rest of the system is sound. It only tells you the cost of one repair. Some homeowners also notice that the unit has become less able to handle the mild winters when a little heat is needed in an addition that has no other source. Together with age and a high repair quote those issues usually send a homeowner looking for replacement options.

We do not blame the original manufacturer. The existing Midea equipment is simply the unit that is already in the house. It may have served through many Austin summers and a few mild winters. Converted garages and room additions often received a single zone ductless system because running new ducts was impractical in older construction. When that system starts to show the signs listed above, replacement becomes a practical conversation. ATX Mini Split King will look at the space, the existing pad, the wall opening, and the electrical circuit. We will tell you plainly whether a new ductless system still makes sense or whether another approach would serve the house better. There are cases, described later, where keeping the current equipment or choosing a different kind of heating and cooling is the better decision. Call (512) 297-7493 if those symptoms match what you see.

How to think about repair versus replacement

Repair is sometimes the smarter money. If the existing Midea unit is relatively new, if the failure is a single inexpensive part such as a capacitor or a fan motor, and if the rest of the system still cools well after that part is changed, then paying for the repair and keeping the equipment makes sense. A TDLR licensed contractor can diagnose the actual fault and give a clear price for that work before anything is taken apart. In an older house or a converted garage the electrical circuit and the line set may still be sound. Spending a modest amount to restore function for several more years is often better than replacing everything. ATX Mini Split King will say so when that is the case. We do not push replacement when a straightforward repair will do the job for a reasonable cost and a reasonable remaining life.

Replacement starts to look better when several things line up against repair. The unit is old, more than one component is failing, the repair quote is high relative to the remaining expected life, and the system already struggles with the long Austin cooling season. Short cycling and extra noise often mean more than one part is worn. In that situation putting more money into the existing Midea equipment can become a series of visits rather than a single fix. Central Texas winters are short and mild, so heating performance is usually a secondary concern, but cooling reliability through months of high temperatures is not. A homeowner should also consider whether the indoor head location still makes sense for how the room is used now. Furniture, a new partition, or a change from garage to living space can leave the old head in a poor spot.

We will tell you a mini split is not the right call when the house already has a working central system that can reach the addition with modest extra ductwork. It is also wrong when the converted garage is used only a few hours a week and a simpler window unit would suffice. If the electrical panel cannot support the new outdoor unit without an expensive upgrade, replacement may cost more than it saves. ATX Mini Split King walks the site and looks at the panel. We tell you if those problems exist. We prefer you repair the existing Midea unit or choose another method rather than install ductless equipment that does not fit the house or the money you want to spend.

Parts that can remain and parts that must be new

The concrete or plastic pad under the outdoor unit can often stay. If it is level and large enough and has good airflow we leave it. The wall penetration can usually be reused if the height is practical and the wall is sound. We inspect the flashing so water stays out. The line set is frequently replaced because the copper may be the wrong diameter or the flares may not match the new valves. When reuse is impossible we install new insulated lines and quote that work in advance. In long Austin summers a leaking or undersized line set will show up as poor cooling even with new indoor and outdoor pieces. We therefore test and measure before deciding. The homeowner is shown the condition of the existing copper and the reason it can or cannot stay.

The disconnect at the outdoor unit and the branch circuit that supplies it can frequently be kept. Code requires the breaker and the conductors to match the new condenser nameplate. If they already do, and the disconnect is in good condition, we leave them. Many older Central Texas houses have an undersized circuit or a disconnect that is no longer acceptable. Then we add a new homerun from the panel or we change the disconnect. That work is priced before we begin. The indoor mounting bracket almost never carries over. Each new indoor head uses its own back plate with a different screw pattern and a different drain stub. We take the old bracket off the wall, repair the drywall or the plaster if the holes do not line up, and mount the new plate so the head sits level and the condensate can leave.

The condensate route is inspected on every job. A gravity drain that still has the proper slope from the indoor head to the outside or to a floor drain can stay. Flexible hose that has become brittle, a pump that no longer lifts the water, or a drain that has been run without a trap or a cleanout will be changed. In a converted garage the drain often exits through the same wall penetration as the lines. We make sure the new head can use that path or we drill a new low point if needed. Nothing about the old Midea equipment is assumed to be compatible. We treat every piece, pad, penetration, lines, power, bracket, and drain, as something to verify on site. The homeowner sees the list of what can stay and what must be new, with prices, before work starts.

Replacement day and the choices you make first

Before the crew arrives the homeowner has already decided three things. First, where each indoor head will hang. That choice affects comfort, condensate routing, and how much wall we have to open. Second, how many zones the new system will have. A single head may be enough for a converted garage. An addition that is now two rooms may need two heads. Third, where the new outdoor unit will sit. Even if we reuse the pad, we confirm it is still the best location for noise, airflow, and service access. Those decisions are made on a site visit, not on the morning of the work. Once they are set, the replacement day itself is straightforward. We arrive, protect the floors, recover any remaining refrigerant from the old Midea unit, disconnect power, and unbolt the indoor and outdoor pieces.

The old indoor head comes off the wall, the old outdoor unit comes off the pad, and both are taken away. We do not leave old equipment on the curb unless the homeowner asks to keep a part. Next we mount the new indoor back plates, run or reuse the line set, make the electrical connections at the disconnect, and set the new condenser on the pad. Vacuum, charge, and start up follow. We check temperatures, look for leaks, confirm the condensate is leaving, and show the homeowner how to use the new controllers. The whole sequence for a one or two head job usually fits in one day. Three heads can take longer if the line sets go in different directions. ATX Mini Split King leaves the site clean and the old equipment removed.

Flat prices and items quoted before any work

A standard replacement of one indoor head and its matching outdoor unit, using the existing pad, an existing wall penetration that we can reuse, and an existing circuit that already meets code, is $1,500. That figure includes the new indoor and outdoor equipment, the labor to remove the old Midea unit, the labor to hang the new head, connect the lines, evacuate, charge, start, and haul the old pieces away. Two indoor heads with one outdoor unit, same conditions, is $2,500. Three indoor heads is $3,500. Those three numbers are the only prices we publish. They assume a straightforward swap in a typical Austin or Central Texas house, addition, or converted garage. If the line set must be replaced, if a new circuit must be pulled, if the pad is broken, or if a condensate pump is required, those items are quoted separately before work starts.

Nothing else is hidden in the flat numbers. Permits, if the city of Austin or the county requires one for the electrical or the mechanical change, are extra and are listed on the pre work quote. Moving the outdoor unit to a new pad location, fishing new wire through finished walls, or opening a second wall penetration are also extra. We would rather you see those costs in writing than discover them after the old unit is already on the truck. ATX Mini Split King is an independent contractor. We buy equipment on the open market and we stand behind the installation because the work is done to code. If the existing Midea system can be repaired for less than the replacement figure, we will say that too. The goal is a clear choice, not a surprise bill.

What to ask an installer and when to keep the existing unit

Ask any installer, including us, whether they are a TDLR licensed contractor and whether the electrical work will be done to the current code. Ask who will pull the permit if one is required. Ask whether they will recover the refrigerant from the old unit instead of venting it. Ask how they will handle the wall penetration so it stays watertight. Ask what happens if the existing line set cannot be reused. Ask for a written list of what is included in the price and what is extra. Those questions apply no matter who you call. They protect you in an older house where hidden rot, undersized wire, or a blocked drain can appear after the old Midea equipment is already gone. A clear answer on each point is more useful than a low first number.

Keeping the existing equipment is the better decision when a single repair will restore reliable cooling for a cost well below the replacement figures above, and when the indoor head is still in a location that serves the room. It is also better when the house electrical service cannot accept another condenser without a costly panel change, or when the space is used so little that even a window unit would be enough. In a mild Central Texas winter the heating function of a mini split is rarely the reason to replace. If the old Midea unit still moves enough air to take the edge off the few cold nights, and if cooling can be restored cheaply, stay with it. ATX Mini Split King will tell you when that is the case. We would rather you spend less and keep what you have.

Questions people actually ask

Can the existing line set stay when the indoor and outdoor units are replaced?

Sometimes. We measure the diameter, inspect the insulation, and check the flares and the oil condition. If the copper matches what the new equipment needs and is free of damage, we can reuse it and keep the price at the flat figure. If it does not match, we quote new lines before work starts. In older Austin houses the original run is often the wrong size or has been patched. Reusing a bad line set would only recreate the cooling problems you already have. We show you the lines and explain the choice on the site visit.

What should I decide before replacement day?

Decide the exact wall for each indoor head, how many zones you need, and the final spot for the outdoor unit. Those three choices control condensate routing, line length, noise, and whether we can reuse the pad and the penetration. We help you choose on a visit before the work is scheduled. Changing your mind after the old Midea unit is removed costs extra time and money. Also decide whether anyone will be home. We need access to the indoor spaces and a place to set the recovered refrigerant tank and the new equipment. Having those answers ready keeps the day short.

When is repairing the existing unit the better choice?

Repair is better when the Midea equipment is not very old, the failed part is inexpensive, and the rest of the system still cools the space after that part is changed. A capacitor, a fan motor, or a simple leak repair can be enough. If the indoor head location still works for the room and the electrical circuit is sound, spending a modest amount now can give several more summers of use. We diagnose first and give a repair price. Only if that price is high compared with remaining life do we talk about the $1,500, $2,500 or $3,500 replacement figures. Keeping what you have is often the honest recommendation.

What extra items are quoted before work instead of included?

New line set, a new electrical circuit or disconnect, a new pad, a condensate pump, extra wall penetrations, and any permit fees are quoted separately. The $1,500, $2,500 and $3,500 figures cover only the standard swap of indoor heads and outdoor unit plus removal of the old Midea equipment when the pad, penetration, circuit and drain can stay. You see the extra list and the prices in writing. No work starts until you agree. That way an older house with hidden problems does not produce a bill you did not expect. We would rather lose the job than surprise you after the old unit is gone.

Is a ductless system always the right replacement in an addition or garage?

No. If the main house already has a central system that can be extended with a modest amount of duct, that path may give more even temperatures and fewer indoor heads to maintain. If the garage or addition is used only occasionally, a window unit or even no mechanical cooling may be enough. If the panel cannot take another condenser, the upgrade cost can make ductless replacement the more expensive choice. ATX Mini Split King looks at the whole house, not just the failing Midea unit. We will say when another approach is smarter. Long summers still need cooling, but a mini split is not the only way.
