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

In Austin and the rest of Central Texas the summers last a long time and stay hot. A mini split that is not cooling leaves indoor spaces uncomfortable, especially in older houses with less insulation, in room additions, and in converted garages that pick up extra heat from the sun. The indoor head may send out air that feels warm or only slightly cool. The outdoor condenser may run for hours without bringing the temperature down. These symptoms appear for many reasons that have nothing to do with any particular brand. Age, dirt on coils, low refrigerant from a leak, or a failing fan motor can all produce the same result. Homeowners notice the problem first on the hottest afternoons when the load is highest.

Short cycling is another common reason people look at this page. The unit turns on, runs for a short time, then shuts off, then starts again. That pattern can come from a thermostat that is poorly placed, from a control board that is acting up, or from a system that is oversized or undersized for the space it serves. Noise is also a frequent complaint. Indoor heads can rattle or hum. Outdoor units can grow louder as bearings wear or as the compressor works harder. None of these signs points to one manufacturer. They simply mean the equipment is not operating the way it did when it was new. In a mild Central Texas winter the heating mode may still work, which can hide the problem until the next summer.

Age itself brings people here. Mini splits last a finite number of years. After that period parts become harder to source and the cost of keeping the unit running rises. A repair quote that comes back high is often the last straw. The homeowner has to decide whether to put more money into equipment that is already old or to start over with a new ductless system. ATX Mini Split King does not sell repairs on every job. We look at the whole picture, including how the house is used and how the existing layout of lines and electrical service will affect a replacement. We name the existing LG equipment only because that is what is on the wall or on the pad today and that is what we would remove.

Repair Versus Replace for an Existing Mini Split

Repair is clearly the smarter money when the failure is isolated and the rest of the system is still in good shape. A capacitor, a fan motor, a sensor, or a small refrigerant leak that can be found and sealed may cost far less than a full replacement. In those cases ATX Mini Split King will say so. We are an independent contractor, so we have no incentive to push a new system when a repair will restore comfort for several more seasons. Central Texas winters are short and mild, so a unit that still heats adequately can be left in place through the cool months while the homeowner plans. The key is an honest diagnosis that looks at the age of every major component, not just the part that failed this week.

Replacement starts to look better when several things have gone wrong at once or when the equipment is simply old. A high repair quote on a unit that already has a noisy compressor, a corroded coil, and a control board that has been replaced once before is a signal to stop putting money in. The homeowner also has to think about how the house is used. An addition or a converted garage may now need its own zone. The original head placement may no longer match furniture or window coverings. In those situations a new ductless system lets you choose the number of indoor heads and where they sit. ATX Mini Split King will walk through that choice before any work begins. We do not assume that more heads are always better.

A mini split is the wrong answer in some houses. If the existing central ducted system still works and the only complaint is one hot room, adding a single head may be overkill. If the electrical service is already at capacity and a new circuit would require a panel upgrade, the extra cost can make replacement unattractive. Older housing in Austin sometimes has limited wall space or historic interiors that owners do not want to cut. In those cases keeping the existing equipment and repairing it, or looking at a different heating and cooling approach, is the better decision. We say that out loud. Our job is to match the equipment to the house, not to sell a ductless system on every visit.

What Stays and What Goes When You Replace a Ductless System

The outdoor pad is one of the items that can carry over. If the concrete or composite pad is still level, free of cracks, and large enough for the new condenser, we leave it in place. A new unit may sit on a slightly different footprint, so we measure before we commit. The wall penetration is another candidate for reuse. The hole that already exists through brick, siding, or wood framing can be used again if the new line set and communication cable fit through it and if the height still matches the indoor head location. In older Austin houses the original hole may be too small or too high, in which case we cut a new one and patch the old opening. We never assume the existing hole will work.

The line set itself usually does not carry over. Copper tubing that has been in service for years may contain residual oil or moisture. The diameter of the liquid and suction lines may not match the new indoor and outdoor coils. Flares at the ends may be damaged. For those reasons we run a new insulated line set on most replacements. The electrical disconnect and the circuit that feeds it can stay if the breaker size, wire gauge, and disconnect rating still meet code for the new condenser. In many Central Texas homes the original circuit is adequate. When it is not, we pull a new circuit from the panel and install a new disconnect. That work is quoted separately before any work starts because it is not part of a standard head count.

The indoor mounting bracket is rarely reused. Each manufacturer uses a different plate, and the old bracket may be bent or corroded. We install a new bracket that matches the new head. The condensate route is a mixed picture. If the existing drain line still slopes correctly to a suitable termination and is free of clogs, we can tie into it. In additions and converted garages the original drain may dump into a spot that no longer works, or it may have been run without a trap. In those cases we install a new condensate line, sometimes with a pump if gravity will not suffice. All of these details are checked on the first visit so the homeowner knows what will stay and what will be new.

What Replacement Day Looks Like and What You Decide First

Before any tools come out the homeowner decides three things. First is head placement. The indoor unit has to sit high on a wall with clear space in front of it so air can reach the room. Furniture, curtains, and artwork all matter. Second is zone count. One head may be enough for a single room or a studio. Two or three heads make sense when the house has an addition, a converted garage, and a main living area that need independent control. Third is where the condenser sits. The outdoor unit needs airflow, a level pad, and a location that does not block a walkway or sit under a bedroom window if noise is a concern. These choices are made on a site visit, not on the day of the work.

On replacement day the crew arrives with the new indoor heads, the outdoor condenser, line set, and electrical materials. The first task is to recover any remaining refrigerant from the existing LG unit and to disconnect the old indoor and outdoor equipment. The old heads come off the walls, the old condenser comes off the pad, and the old line set is pulled if it is not being reused. We protect floors and furnishings. In an occupied house the work is sequenced so that one zone can stay running if the homeowner needs it, though that is not always possible. The wall openings are inspected and, if needed, enlarged or relocated. Electrical lockout is performed at the disconnect and at the breaker.

New brackets go on the walls, new heads are hung, and the new line set is run, brazed or flared, and insulated. The condenser is set on the pad, leveled, and connected. The circuit is landed, the disconnect is closed, and the system is vacuumed, charged, and started. Condensate lines are run to the chosen termination. The crew checks each indoor head for airflow, temperature drop, and quiet operation. At the end of the day the old equipment is hauled away, debris is cleaned up, and the homeowner is shown how to use the new controllers. The whole process for a one, two, or three head job typically finishes in a single day if the electrical and drain work is standard. Non standard items that were quoted ahead of time are completed as well.

Flat Pricing for Standard Replacement Jobs

ATX Mini Split King uses flat pricing for the most common replacement jobs. A single indoor head with its matching outdoor condenser, line set, and labor is $1,500. Two indoor heads sharing one outdoor unit, with line sets and labor, is $2,500. Three indoor heads with one outdoor unit, line sets, and labor is $3,500. Those figures cover materials and labor for a standard installation in Austin and Central Texas. The existing LG equipment is removed as part of the job. The prices assume the outdoor pad can be reused or is already in place, the wall penetrations are usable or require only modest enlargement, and the electrical circuit and disconnect are adequate. Anything outside that scope is identified on the first visit.

Included in those flat prices are the new indoor heads, the outdoor condenser, new insulated line sets of ordinary length, new mounting brackets, basic condensate drains that can use gravity, recovery and removal of the old equipment, start up, and a single day of labor by our crew. Work is done to code by a TDLR licensed contractor. We do not add hidden fees for ordinary travel inside our Austin and Central Texas service area. The homeowner receives a written description of what is included before we schedule the work. If the job stays within the assumptions listed above, the price does not change on the day of installation.

Items that get quoted separately before any work starts include a new electrical circuit or panel work, a condensate pump, extra long line sets that must travel across a roof or through multiple walls, masonry cutting that requires a specialist, interior patching and paint, and any structural changes to the pad or the wall. We also quote separately if the homeowner wants a different number of heads than the one, two, or three packages, or if the condenser must be placed on a roof or a wall bracket instead of a ground pad. None of that work begins until the extra cost is written down and agreed to. That keeps the job honest and lets the homeowner decide whether the extra items are worth it.

Questions to Ask Before You Hire and When to Keep What You Have

Ask any installer whether they are an independent contractor or whether they have a relationship with a particular manufacturer. ATX Mini Split King has none. Ask whether the work will be done to code by a TDLR licensed contractor. Ask how they decide what existing parts of the system can stay and what must be replaced. Ask for a written list of what the quoted price includes and what will be billed extra. Ask how they protect the house during the work and how they dispose of the old equipment. In Central Texas you should also ask whether they have experience with older housing, room additions, and converted garages, because those spaces often have odd wall construction and limited electrical capacity.

Ask what happens if the line set length or the electrical service turns out to be different from the original estimate. A good answer is that the extra work is quoted and approved before it starts, not billed as a surprise at the end of the day. Ask how many people will be on site and how long the job is expected to take. Ask whether the indoor heads can be placed exactly where you want them or whether there are limits based on line set length and condensate slope. These questions help you compare installers on process rather than on promises. ATX Mini Split King answers them the same way for every homeowner. We would rather lose a job than start work with unclear expectations.

Keeping the existing equipment is the better decision when a modest repair will restore function, when the electrical upgrade needed for a new system is too expensive, or when the layout of the house simply does not suit ductless heads. If the current LG unit still cools most of the time and the only issue is a noisy fan that can be replaced, spend the smaller amount. If the panel is full and a service upgrade would cost more than the new mini split itself, wait. If the rooms are so open or so oddly shaped that heads cannot deliver even air, a different approach may be wiser. ATX Mini Split King will tell you when that is the case. Call (512) 297-7493 to talk through the options for your house.

Questions people actually ask

Will you repair my existing LG unit instead of replacing it?

Yes, when repair is the smarter money. If the problem is a single part and the rest of the system is sound, we will say so and we will not push a replacement. ATX Mini Split King is independent and has no relationship with LG or any other manufacturer. We look at age, the cost of the repair, and how the house is used. Central Texas summers are long, so we also consider whether the unit will last through another hot season. Call (512) 297-7493 and we can discuss what we find on a visit.

What is included in the $1,500, $2,500, and $3,500 prices?

Each price covers the indoor heads, the outdoor condenser, ordinary line sets, brackets, basic gravity drains, removal of the old equipment, labor, and start up for a standard job. The $1,500 figure is one indoor head. The $2,500 figure is two heads. The $3,500 figure is three heads. Electrical upgrades, condensate pumps, extra long lines, and interior finish work are quoted separately before work starts. We put the inclusions in writing so there is no confusion on installation day.

Can the outdoor pad and wall hole be reused?

Often the pad can stay if it is level and large enough for the new condenser. The wall penetration can be reused if the new line set fits and the height still works for the indoor head. We check both on the first visit. In older Austin houses or additions the original hole may be the wrong size or in the wrong place, so we cut a new one and close the old opening. Those changes, if needed, are identified and quoted before the work begins. Nothing is assumed.

What do I need to decide before replacement day?

You decide indoor head placement, how many zones you want, and where the outdoor condenser will sit. Head placement has to allow clear airflow and a path for the line set and drain. Zone count depends on how the house is divided, including any addition or converted garage. Condenser location needs a level pad, airflow, and a spot that does not create a noise problem for a bedroom. These choices are made on a site visit with ATX Mini Split King. Once they are set, the installation day can proceed without last minute changes.

When is a mini split the wrong choice for my house?

A mini split is the wrong choice when a working central system already covers the house and the complaint is minor, when electrical capacity is too limited without a costly upgrade, or when the rooms are too open or too cut up for heads to work well. Older housing with historic interiors may not want new wall penetrations. In those cases repairing the existing equipment or looking at another approach is better. ATX Mini Split King will say so. We match equipment to the house rather than selling a ductless system on every call. Phone is (512) 297-7493.
