When a room in your home gets too hot or too cold, you have two common options: add a new vent run to your existing ductwork or install a ductless mini split. Both can solve the problem, but the costs and benefits are very different.
When a room in your home gets too hot or too cold, you have two common options: add a new vent run to your existing ductwork or install a ductless mini split. Both can solve the problem, but the costs and benefits are very different.
At Jester Climate, we install mini splits across Central Texas. Our pricing is simple: a flat $2,400 for a standard installation, materials and labor included. We also run a weekly Joker Day with a lower price. This page compares that fixed cost against the variable cost of extending your ductwork.
Extending your home's ductwork to reach a new room involves materials like sheet metal, flexible duct, and insulation, plus labor for cutting into the trunk line and running the duct through the attic or crawlspace. The total cost depends heavily on the distance from the main duct, the accessibility of the attic, and whether your existing HVAC system has enough capacity to condition the extra space. In many older Austin homes, ductwork is already maxed out. Adding a vent might also require a return air path or a larger unit. The cost can range from a few hundred dollars for a simple short run to well over $2,400 for a complex installation. If your central system is undersized, you might need to upgrade the whole AC unit, which is far more expensive.
A ductless mini split is a self contained system that cools one room or zone. No ductwork is needed. Jester Climate offers a flat $2,400 for a standard installation. That includes the indoor head, outdoor condenser, line set, wall bracket, electrical hookup, and all labor. A $400 deposit books your install day. The remaining $2,000 is due after we start the system and show you it's working. You pay by card through our secure checkout. One day each week is Joker Day: the price is lower than $2,400. The exact Joker price changes weekly and is shown on our homepage. So you might get an even better deal if you can be flexible with your install date.
There is no single right answer. If your existing ductwork is well designed and your HVAC system has extra capacity, adding a vent could be the cheaper route. But if your ducts are leaky, undersized, or in a hot attic, the efficiency loss can cost you more in utility bills over time. Mini splits avoid duct losses entirely. They also let you control each room independently. In Central Texas summers, keeping a bonus room or home office cool without over cooling the whole house is a big plus. On the other hand, if you only need a little air to reach a small bathroom or closet, a short vent run might be all you need. The honest answer: a mini split is often the better long term investment for rooms that are far from the main unit or have poor duct access. But for a straightforward job close to the main trunk, a vent can save you money upfront.
The cost varies widely. For a short run with easy attic access, you might pay between $500 and $1,200. For a long run across a two story home or through a finished ceiling, the cost can easily exceed $2,400. Without seeing your home, it is impossible to give a precise number. A mini split gives you a fixed price of $2,400 no matter how complex the install.
A mini split delivers direct, powerful cooling right where you need it. Central air loses some cooling through ductwork, especially in hot attics. In many Austin homes, a mini split will cool a room more quickly and evenly. However, if your central system is already oversized and ducts are well insulated, a vent may work just as well. The mini split has the added benefit of not affecting the rest of the house's balance.
Permit requirements vary by city. In Austin and most Central Texas communities, electrical work for a mini split or cutting into ductwork for a vent often requires a permit. Jester Climate handles all required permits for mini split installations as part of our service. For vent work, your HVAC contractor should do the same. Always ask before hiring.
For occasional use, a window unit or portable AC is the cheapest option. But they are less efficient, noisier, and block windows. A mini split is a more permanent solution that adds value to your home and operates very quietly. If you plan to use the room regularly, even seasonally, a mini split is a worthwhile upgrade. If it is just for a few days a year, a simple vent or a window unit might be enough.
