Replacing an existing Goodman unit in Austin

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

A high repair quote often prompts the same question. ATX Mini Split King is an independent HVAC and electrical contractor in Austin and Central Texas. We remove the old unit and install ductless systems to code by a TDLR licensed contractor. Call (512) 297-7493.

ATX Mini Split King is an independent HVAC and electrical contractor. We are not affiliated with, endorsed by, or a representative of Goodman or any manufacturer. The Goodman 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 homeowners look at replacing an existing Goodman unit

The most common reason a homeowner in Austin reaches this page is that the existing Goodman unit is not cooling the house through a long Central Texas summer. Rooms stay warm even with the thermostat turned down. Short cycling is another sign people notice. The unit starts, runs briefly, stops, then repeats. That pattern leaves humidity high and temperatures uneven. The equipment may also have grown loud. A rattle, a vibration, or a fan noise that was never there before can make the living room or a bedroom hard to occupy. Age matters too. Older housing stock, additions, and converted garages often still run equipment that has already lived through many summers and short mild winters. A repair quote that looks large relative to remaining useful life is the last common trigger.

None of those symptoms by themselves prove the equipment must be replaced. A dirty coil, a low refrigerant charge from a slow leak, a failing capacitor, or a control board that has seen better days can produce the same list. ATX Mini Split King does not assume replacement is the answer. We look at the actual condition of the existing Goodman unit, the age of the line set and electrical, and the layout of the house. Central Texas summers put heavy load on any cooling system. Mild winters mean heating is less of a driver, but a system that cannot cool will make July and August miserable. Additions and converted garages often have their own equipment that was never sized or maintained the same way as the main house. That is the context we work in every day.

We describe the symptoms this way because they are what you actually feel and hear. We do not attach them to any manufacturer story. The existing Goodman unit is simply the equipment that is in the house today. If it can be repaired at a cost that makes sense, that is often the better path. If the repair is large, parts are hard to source, or the rest of the system is worn, then a conversation about ductless replacement is reasonable. Older Austin houses and garage conversions frequently have limited attic or crawl space, which is one reason people consider a wall mounted indoor head instead of another ducted machine. That decision comes later. First we establish whether the current unit is worth keeping.

Repair or replace, an honest look at the money

Repair is often the smarter money. When the compressor and coils on the existing Goodman unit are still sound, a limited repair can restore cooling without a full replacement. Capacitors, contactors, fan motors, and control boards fail on every brand of equipment. Those are ordinary parts. A refrigerant leak that can be found and sealed is another case where repair makes sense. Central Texas has long hot summers, so cooling performance matters more than heating. If the unit still moves enough air and the electrical is safe, keeping it is reasonable. ATX Mini Split King is an independent contractor. We will say so when repair is the better path. We do not have a relationship with Goodman of any kind. The brand name is only a label for the machine that is already in your house.

Replacement starts to look better when several things are true at once. The repair quote is large because multiple components are tired. The line set is old and may not be reusable. The indoor coil or blower is matching the outdoor unit and both are worn. The house has an addition or a converted garage that the current system never served well. Ductless can put a head exactly where the heat and the people are. That is a layout advantage, not a brand story. Drawbacks exist. Indoor heads are visible on the wall. Some people dislike the look. We will say so at the site visit if the existing ducted system can be repaired cheaply and the ducts themselves are in good condition and already reach every room you care about. We say that out loud.

We also consider how you use the house. If you live in two rooms most of the time, one or two indoor heads can be enough and the rest of the house can stay as it is. If every bedroom and the living area need even temperatures, more heads or a different approach may be required. That is a conversation, not a sales pitch. Electrical capacity in older Austin homes is another real limit. A new circuit or a panel change is extra work that we quote before anything starts. None of this is mysterious. The goal is to spend money only where it improves comfort or avoids a larger future repair. Sometimes that means leaving the existing Goodman unit in place after a modest repair.

What carries over from the old installation and what does not

The outdoor pad under the existing condenser can often stay in place. If the pad is level, structurally sound, and large enough for the new outdoor unit with proper clearance, we reuse it. Cracked pads, pads that have settled, or pads sitting in a drainage problem area get replaced. That extra work is quoted before we start. The wall penetration that currently carries the line set and control wire may also be reusable. A properly sleeved hole through siding, brick, or a framed wall can be used again if the new indoor head sits in a similar location. When the head moves to a different wall, or when the existing hole is undersized or poorly sealed, we cut a new penetration and close the old one. Both the new hole and the patch are billed as separate items.

The existing line set is frequently not reusable. Copper that has been in a wall or buried for years may have kinks, corrosion, or oil residue that does not belong in a new system. We inspect it. If it is the right diameter, the right length, clean, and pressure tight, we can consider keeping it. In practice we often run new line set because the cost of a future leak inside a wall is high. The disconnect at the outdoor unit and the circuit that feeds it are electrical items. If the breaker, wire gauge, and disconnect are already correct for the new outdoor unit and the run is in good condition, they stay. Older houses in Austin often have undersized circuits or worn disconnects. Upgrading those is quoted separately and done to code by our TDLR licensed contractor.

The mounting bracket that holds the indoor head of the existing Goodman unit is almost never reused. Brackets are specific to the chassis they were made for. We install a new bracket matched to the new indoor unit. The condensate route is a separate question. If the current drain is a gravity line that already falls correctly to an approved termination, and it is clear, we may tie into it. Clogged, undersized, or uphill drains get replaced. Condensate pumps are added when gravity will not work, for example in a converted garage with a slab and no nearby drain. Pump installation and a new drain run are quoted before work. We do not guess. You see the extras on paper first.

What the replacement day looks like and what you decide first

Before any tools come out you decide three things. Head placement for each indoor unit. How many zones you need. Where the outdoor condenser sits. Placement is about throw of air, noise at night, and the look of the wall. You choose the wall because you see it every day. Zone count follows how you live. An open living area can often take one head. Separate bedrooms used at night may each get a head so they can be turned off. Additions and converted garages in older Central Texas houses are frequently their own zone. Condenser location needs airflow, a level pad, and a short line set run. We walk the site with you and mark locations before the day of work.

On the day we arrive, protect floors, and recover refrigerant from the existing Goodman unit according to the rules. The old outdoor unit comes off the pad. The old indoor coil or head comes off the wall or out of the closet. We cap and abandon or remove what will not be reused. New line set, communication wire, and condensate tubing go in. The new indoor head mounts on its bracket. The new outdoor unit sets on the pad. We make the electrical connections at the disconnect, vacuum the lines, charge the system, and start it. We check temperatures, airflow, and drain. You see it run before we leave. The house stays occupied. Work is noisy for a few hours but we do not need the whole day in every case. Complex multi head jobs or electrical upgrades take longer and we tell you that in advance.

Permits, if the city or county requires them, are pulled by us before the work day. Austin and nearby towns often want inspection of the electrical circuit and the mechanical installation. We take care of the paperwork. You do not have to stay home the whole time. Someone should be present at the start to confirm the marked head locations and at the end to watch the system start and to walk through basic operation. We protect flooring and furniture, then we clean the work areas when we finish. The old Goodman equipment is removed from the site unless you ask to keep a component. The day is ordinary job site work. There is noise, there is copper being brazed or flared, and then the system runs.

Flat pricing, what is included, and what is quoted separately

A standard one indoor head replacement, including the outdoor unit, line set, indoor head, mounting, electrical connections, condensate, recovery and removal of the existing Goodman equipment, and startup, is $1,500. Materials and labor are included. A two head system is $2,500. A three head system is $3,500. Those prices assume a typical wood frame or standard masonry wall, a usable or simple outdoor pad, a reasonably short line set route, and electrical that is already close to what the new outdoor unit needs. ATX Mini Split King is an independent HVAC and electrical contractor in Austin and Central Texas. Work is done to code by a TDLR licensed contractor. The price holds for the stated scope. We do not change it after you agree unless you change the scope.

Anything that is not standard is quoted in writing before work starts. Examples include a long line set run across a roof or through a finished attic, a new circuit from a distant panel, a panel upgrade, a condensate pump and long drain, cutting and patching masonry that is not ordinary brick, a new poured pad in a difficult location, or extra indoor heads beyond three. We do not start until you have those numbers. If the existing electrical is unsafe we stop and quote the correction. Mini splits are the wrong answer for some houses. A large home that already has good ducts and a repairable central system does not need wall heads in every room. We will say that. Call (512) 297-7493 and we will walk the job before any price is final.

You see every extra on paper before we schedule. No extra work starts without agreement. Older Austin houses, 1960s and 1970s ranches, garage conversions, and room additions often need one or more of those extras because the original electrical, the original pad, or the original wall chase was never meant for a second system. We treat that as normal, not as a surprise. The flat figures of $1,500, $2,500, and $3,500 cover the core install when the site is ordinary. When the site is not ordinary you still get a number first. That is the whole pricing story. There is no other published price. We would rather lose a job than invent a number on the truck. Call (512) 297-7493 if you want the walk through.

Questions to ask before you hire, and when you should keep the equipment you have

Ask any installer whether they are independent or tied to a manufacturer. ATX Mini Split King is independent and has no relationship with Goodman of any kind. Ask who holds the TDLR license and whether the electrical and mechanical work will be pulled and inspected. Ask what happens to the old line set, the old pad, and the old disconnect. Ask how they will route condensate and whether a pump is likely. Ask what is included in the number they give you and what will be extra. Ask them to walk the house and mark head locations with you, not from a photo. Ask when they would tell you to repair the existing Goodman unit instead of replacing it. The answer to that last question tells you a lot.

Keeping the existing equipment is the better decision when a limited repair will restore cooling, the ducts or the current heads already serve the rooms you use, and the electrical is safe. It is also better when you do not want indoor units on the walls, or when the house is large and a ductless system would need more heads than you want to look at or pay for. A mini split is a poor fit if you need even temperatures in many closed rooms and you already have a working duct system that only needs a modest repair. Central Texas summers are long, but that fact alone does not force a replacement. If the existing Goodman unit still does the job after a straightforward repair, leave it. We will tell you that on the phone or on site. Phone is (512) 297-7493.

Ask about insurance, about who actually turns the wrenches, and about how they handle a callback if the new system does not start or the drain overflows. Ordinary questions. Also ask whether they will recover the refrigerant legally and whether they will pull permit when the jurisdiction requires it. If an installer cannot answer those items in plain language, keep looking. ATX Mini Split King answers them. We are an independent HVAC and electrical contractor. The work is to code. If replacement is not the right move we would rather you spend the repair money and stay comfortable through the next summer. That is the whole pitch. There is no other relationship and no other claim.

Questions people actually ask

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

Sometimes. We inspect diameter, length, condition, and cleanliness. Copper that is kinked, corroded, or full of old oil is not worth the risk of a hidden leak. When the line set is the right size, short, and pressure tight we can consider it. In many Austin houses the line set is old enough that we run new. That extra, if it is extra, is quoted before work. Reusing a bad line set is a way to create a callback. We would rather replace it when it is questionable.

When is repair the better choice than a new ductless system?

Repair is better when the compressor and coils are still sound, the repair is limited, and the equipment already cools the rooms you occupy. A capacitor, a motor, a leak that can be sealed, or a control issue can be enough. If ducts already reach the space and they are in good shape, replacing the whole thing with wall heads may be unnecessary. We look at the existing Goodman unit as the machine that is there, not as a brand to remove. If a modest repair gets you through more summers, do that. We will say so.

What do I need to decide before replacement day?

You decide indoor head locations, how many zones you actually need, and where the outdoor unit will sit. Walk the rooms. Think about night time noise in bedrooms and about the look of a head on the wall. Open plans can share a head. Additions and converted garages often need their own. The condenser needs airflow and a short line path. We mark those spots with you before the crew arrives. Electrical capacity in older Central Texas houses can force a quoted extra. Knowing that in advance is part of the decision. Call (512) 297-7493 and we can walk it with you first.

Is a mini split the right replacement for every house in Austin?

No. If your ducts are sound and a repair will make the existing system cool again, keep it. Indoor heads are visible. Some owners do not want that. A house that needs many closed rooms held at even temperature may be better served by repaired ducts than by a cluster of wall units. Converted garages and additions are often a good fit because they were never on the original system. Whole house replacement with ductless is a choice, not a requirement. We say when it is the wrong answer. ATX Mini Split King would rather repair than install heads you will regret looking at.

How do I get a number for my house?

Call (512) 297-7493. ATX Mini Split King will ask about the existing Goodman unit, the symptoms, the age of the house, and whether you have an addition or converted garage. We can often give the flat $1,500, $2,500, or $3,500 figure if the site sounds ordinary. If electrical, pad, line set path, or masonry looks non standard we come look and quote those items before any work. You get the extras in writing. No relationship with any manufacturer is involved. We are an independent TDLR licensed contractor doing the work to code in Austin and Central Texas.
