Replacing a Gas Pack With a Mini Split in Georgetown, Texas

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

Many homes in Georgetown rely on a single outdoor gas pack unit to manage summer cooling and winter heating. These packaged systems sit outside on a ground slab, pushing conditioned air through crawlspace or attic ducts. When an older unit struggles in long Central Texas heat waves, switching to a ductless mini split system provides a practical and efficient heating and cooling alternative for your living space.

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.

Understanding How a Gas Pack Operates

A gas pack is a self-contained heating and air conditioning system where all major parts reside in one metal cabinet sitting outside the house. Unlike split systems that separate the indoor coil from the outdoor compressor, a packaged unit houses the evaporator coil, condenser coil, blower motor, compressor, and natural gas or propane burner together. Outdoor air flows through the unit to cool the refrigerant, while indoor air is drawn out of the home, conditioned inside the cabinet, and circulated back indoors.

The connection between the house and the packaged unit relies on two large sheet metal duct passages cut through the exterior wall or foundation. One duct pulls air from the house into the return section of the unit, while the other pushes heated or cooled air back into the supply ductwork. From there, standard metal or flexible ducts distribute air throughout the rooms of the home. This mechanical design keeps combustion and mechanical noise completely outside the living areas.

Honest Advantages of a Packaged Gas System

Packaged gas systems remain popular in older Georgetown properties and ranch style homes because they save valuable interior space. Since everything sits outside on a concrete pad, homeowners do not lose closet space or attic clearance to an indoor air handler or gas furnace. In addition, maintenance technicians perform almost all inspections, filter changes, and repairs outside, which prevents dirty equipment and service tools from being hauled through the interior of the home during routine service calls.

Another major advantage is the strength and reliability of gas heating during sudden Texas cold snaps. Natural gas produces steady, high-temperature heat at the supply registers without needing supplemental electric resistance heat strips. For properties connected to city gas lines or on-site propane tanks, a packaged gas unit provides dependable comfort during winter freezes. Having only one combined piece of equipment also means you only manage one outdoor footprint rather than multiple mechanical boxes around your yard.

Drawbacks and Limitations of Gas Pack Units

Because the entire unit sits outdoors year round, a gas pack suffers constant exposure to harsh Central Texas weather. Intense summer sun, blowing dust, heavy thunderstorms, and hail beat down on the metal cabinet, electrical components, and coils. Over time, metal parts rust, wiring deteriorates, and plastic components become brittle. Moisture accumulation around the base of the outdoor unit can also corrode the lower sheet metal casing and degrade the structural integrity of the base pan.

These units also rely entirely on extensive ductwork that often runs through unconditioned crawlspaces or scorching attics. In neighborhoods with older pier and beam foundations or converted garage spaces, air leaks and thermal losses along the duct runs reduce overall comfort. Furthermore, a single packaged unit creates one broad temperature zone for the whole house. Rooms furthest from the outdoor cabinet often suffer from weak airflow, resulting in hot bedrooms during summer afternoons and uneven heating across different areas of the house.

Signs Your Gas Pack Is Reaching End of Life

Age and environmental wear eventually cause gas pack systems to fail. One serious warning sign is visible rust or physical corrosion on the burner assembly, exhaust flue, or heat exchanger. Cracks in a gas heat exchanger create serious safety hazards that require immediate equipment shutdown. If you smell odd combustion odors, hear metal popping noises when the heat starts up, or notice that the gas burner repeatedly cycles on and off without warming the house, the unit is nearing the end of its operational life.

On the cooling side, an aging compressor will struggle during peak summer temperatures in July and August. You might hear loud humming, buzzing, or clicking sounds as the outdoor motor attempts to start. Weak cooling output, rising electric bills, and frequent refrigerant leaks in the outdoor coils also indicate critical failure. When the cost of replacing specialized fan motors, circuit boards, or compressors approaches the value of the machine, continuing to patch the system is no longer practical.

The Mini Split Replacement Process and Flat Pricing

Replacing an old gas pack with a ductless mini split starts with safely disconnecting the existing electrical service, gas lines, and ductwork. The old outdoor unit is removed from the property. Next, the large supply and return openings through the exterior wall or foundation are sealed with durable insulation, backing materials, and weatherproofing to protect the structure against water intrusion and pests. The crew then sets a new, compact outdoor heat pump unit on a level pad or secure wall bracket.

Inside, sleek wall-mounted indoor air handlers are positioned in primary living areas and bedrooms according to your preference. Thin refrigerant line sets, power cables, and gravity condensate drain lines run from each indoor unit through a neat three-inch hole to the outdoor condenser. All lines are protected inside decorative exterior covers that match the exterior finish. An installation is typically completed in a single day, leaving the homeowner with independent temperature controls for individual rooms.

ATX Mini Split King offers simple flat pricing for standard installations. Pricing is $1,500 for one indoor head, $2,500 for two indoor heads, and $3,500 for three indoor heads, with all standard materials and labor included. Any non-standard requirements, such as extended line set runs, awkward mounting locations, or an electrical panel upgrade, are quoted clearly before any work starts. All work is completed to code by a TDLR licensed contractor. Call (512) 297-7493 to discuss your layout.

When You Should Keep Your Existing Setup

Switching to a ductless mini split is not the right choice for every property in Georgetown. If your current gas pack is less than ten years old and only needs an inexpensive fix like a new capacitor, contactor, or flame sensor, repairing the existing unit is the smart financial move. It makes little sense to replace a functional system prematurely when a quick, affordable repair can keep your home comfortable for several more seasons.

Staying with a traditional ducted system also makes sense if your existing ductwork is in great condition and your home has an open floor plan that heats and cools evenly. Homeowners who dislike the appearance of indoor wall-mounted heads may also prefer sticking with central ducted equipment. If you want to keep gas as your primary heating fuel and already have sound ductwork in place, installing a new ducted package unit will often serve your lifestyle better than going ductless.

Questions people actually ask

What happens to the large holes in the wall when the gas pack is removed?

When the old unit is taken away, two large duct penetrations remain in the exterior wall or skirting. Our crew frames in the opening, installs exterior sheathing, seals the seams against air and water leaks, and adds solid insulation. The exterior is finished to protect your home from weather and pests, while interior vents connected to the old trunk line can be closed off or covered.

Can a ductless mini split handle hot Georgetown summers?

Yes. Modern ductless mini splits use variable-speed compressors that adjust output continuously to match the heat load of your home. Because the cool air is delivered directly into the room without passing through hot, leaky attic ducts, the system cools rooms rapidly and maintains consistent indoor comfort even during long stretches of triple-digit Central Texas summer heat.

Will I need to upgrade my home electrical panel for a mini split?

Most homes have adequate electrical capacity, especially since the old gas pack already had dedicated outdoor power wiring. However, older homes with small service panels might require an electrical update depending on how many indoor zones are added. If a panel upgrade is necessary, ATX Mini Split King evaluates the electrical service and quotes any required upgrades before starting the job.

How does heating with a mini split compare to gas pack heating?

A ductless heat pump provides steady, quiet heat by extracting thermal energy from outdoor air and moving it inside. While gas furnaces blow short bursts of very hot air, a mini split produces continuous, gentle warmth that keeps room temperatures even. Modern heat pumps operate reliably through typical Central Texas winter temperatures without requiring separate gas hookups or burner maintenance.

How long does the replacement process take?

A typical gas pack removal and ductless mini split installation takes our crew one full working day. In that time, we remove the existing outdoor packaged unit, seal the duct openings, mount the indoor air handlers, run the line sets and drain lines, complete the electrical connections, and test the entire system to ensure proper heating and cooling operation before we leave.
