A full central air installation in Austin typically runs $3,500 to $7,500, depending on the size of your home, the condition of your existing ductwork, and whether your electrical panel can handle a modern high-efficiency system. We’re Cold Harbour Heating and Air Austin, and we’ve been putting systems into Austin homes long enough to know that a new AC is only as good as the house it’s going into. If you’re in Hyde Park, Travis Heights, Northwest Hills, or anywhere else in the Austin metro, call us at (361) 204-1605 and we’ll give you a straight answer about what your home actually needs.
We know Austin’s houses the way a mechanic knows a car that’s been on the road for 60 years. Older bungalows, 1970s two-stories, brand-new builds in Steiner Ranch: each one presents a different set of problems when it’s time for AC Installation. That’s why we don’t do like-for-like swaps without first checking what’s behind the walls and above the ceiling. More on that below.

Why Cold Harbour Heating and Air Austin Is Austin’s Preferred AC Installation Company
We’ve worked in Austin long enough to know the difference between a house in Travis Heights and a house in Circle C. The older the home, the more careful the install has to be. A 1940s bungalow with original cast-iron ducts and a 100-amp panel is not the same job as a 2015 build with sealed flex ducts and a 200-amp service. Homeowners here have been burned before, usually by companies that quoted low over the phone and then “found” problems after the old unit was already ripped out. We hand you a written price before a single tool comes out, and that price does not change at the door.
Victor Mancini, who leads our Austin operation, has built the team around a simple rule from the Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails. Every installer who walks through your door in Austin is background-checked and uniformed, so you know exactly who’s in your home. And when you call at 2 a.m. on a July night because the house won’t cool, a live person picks up. No voicemail tree. No answering service reading from a script.
We train our technicians on nine major residential brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Austin, where a single street can have 40-year-old furnaces next to brand-new heat pumps. The technician who shows up knows how to work on all of it.
Styles & brands we work with







Central Air Conditioning Installation in Austin
Central Air Conditioning Installation in Austin means more than bolting a new condenser onto the slab and calling it done. The job starts with a load calculation that accounts for your home’s square footage, window orientation, insulation levels, and how much air your existing ductwork can actually move. In Austin’s climate, with over 100 days a year above 90°F and humidity that makes the air feel like a wet blanket, a system that’s sized or installed wrong will announce itself by August. You’ll know because the upstairs won’t cool, or the unit will short-cycle, or your electric bill will look like a car payment.
Most central air installations in Austin run $3,500 to $7,500. The price covers the condensing unit, indoor coil or air handler, line set, pad or wall bracket, thermostat wiring, refrigerant, and labor. What it doesn’t cover, unless we find it during the initial inspection, is ductwork repair, electrical panel upgrades, or major modifications to your existing plenum. Those are separate line items, and we’ll walk you through every one of them before you sign anything.
Ductwork and Airflow Assessment
Before we quote a central air install in Austin, we inspect the ducts. Many older Austin homes are losing 20 to 30 percent of conditioned air through leaks in cast-iron or vintage duct runs. Installing a high-efficiency unit on top of leaky ducts is like putting a new engine in a car with a hole in the gas tank. If we find duct leakage, we’ll show you the measurements and give you a price to fix it, either as part of the install or as a separate job.
Electrical Requirements
A modern compressor pulls more starting current than a lot of older panels can supply. If your Austin home still has a 100-amp panel, we may need to upgrade it to 200 amps before the new system goes in. We’ll tell you during the estimate, not the morning of the install.
Furnace Installation in Austin
Furnace Installation in Austin might seem like an afterthought when it’s 100° outside, but Austin’s winter freezes are real. The February 2021 storm knocked out heat across the city, and plenty of homeowners discovered their 1980s furnace had been limping along for years. A new furnace costs $3,500 to $7,500 installed, and the right unit for your Austin home depends on your current fuel source and whether you want to pair it with a heat pump for year-round efficiency.
Natural gas furnaces are most common in Austin’s older neighborhoods, while newer subdivisions often run all-electric with a heat pump. We install both, and we’ll explain the difference in plain language: a gas furnace burns fuel to make heat, while a heat pump moves heat from outside to inside, which works even when it’s cold out. In Austin’s climate, dual-fuel systems are increasingly popular because the heat pump handles mild winter days and the gas furnace kicks in when temperatures drop below freezing.
Furnace Replacement vs. Repair
A heat exchanger crack is the big one. Once a furnace’s heat exchanger fails, replacement is the only safe option, and we’ll show you the crack before we ever ask you to make a decision. Furnace repair in Austin runs $150 to $700, but when a unit is past 15 years old and the repair is pushing $500, replacement often makes more sense. We’ll give you both prices and let you choose.
Pairing with a Heat Pump
If you’re replacing both your furnace and your AC, a dual-fuel setup gives you the best of both: efficient cooling in the summer and reliable heat in the winter. We install Daikin, Bryant, and American Standard dual-fuel systems in Austin homes regularly, and the combined system usually costs less than installing both separately.
Trusted Brands We Service in Austin
We service and install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That covers just about every furnace and condenser sitting in an Austin home today. We keep common parts stocked locally for Austin customers, which means when a capacitor fails or a control board burns out, we’re not waiting on a warehouse in Houston. For installations, we order the equipment specific to your home’s load calculation, and we’ll show you the model numbers before we place the order.

AfterCommon AC Installation Problems We See in Austin Homes
- Undersized original ductwork. In homes built before 1950, the ducts were sized for gravity furnaces or early forced-air systems, not modern high-efficiency heat pumps. A new system starves for airflow, and the back bedrooms never cool.
- Single-zone systems on two-story floor plans. Northwest Hills and other 1970s-era subdivisions are full of two-story houses with one thermostat. The upstairs runs 10° hotter, and no amount of adjusting the vents fixes it.
- 100-amp electrical panels. A modern compressor’s starting current can trip an old 100-amp breaker on the first hot afternoon. We check panel capacity on every Austin install.
- Heat island effect in central neighborhoods. Areas around The Drag and downtown hold heat long after sunset. Undersized or aging systems simply can’t keep up, even when they’re running constantly.

A 1.5-ton system for a small bungalow in Travis Heights will land at the low end. A 5-ton high-efficiency system with duct retrofit and a panel upgrade in a 3,500-square-foot house in Circle C will land at or above the high end.

FAQs About AC Installation in Austin
The most common reason is that your ductwork is leaking or undersized for the system, so a new unit is pushing conditioned air through the same failing channels the old one used. In Hyde Park and other pre-1950 Austin neighborhoods, original cast-iron ducts often lose 20 to 30 percent of airflow before it ever reaches a register. The fix is usually a duct retrofit, either a high-velocity mini-duct system or sealed and insulated replacement runs, not a larger unit. Call (361) 204-1605 and we’ll measure your duct leakage before recommending anything.
If your home still has a 100-amp panel, yes, there’s a good chance you’ll need a 200-amp upgrade before a modern high-efficiency condenser can be installed safely. Newer compressors pull a large inrush current on startup that old panels can’t handle, and you’ll see breakers trip on the first hot afternoon. We check panel capacity during the estimate and include the upgrade in your written price if it’s needed. Never sign a contract for an AC install in an older Austin home without having the panel inspected.
SEER2 is the new efficiency testing standard that took effect in 2023, and it measures performance under more realistic operating conditions than the old SEER test. A unit rated 16 SEER under the old standard might be 15.2 SEER2, so the numbers look slightly lower even though the equipment is just as efficient. For Austin’s climate, we recommend a minimum of 15.2 SEER2 for most homes, and higher if you plan to stay in the house long term. We’ll explain the rating on every unit we quote and show you the actual efficiency documents.
No, and we won’t do it. A new condenser paired with an older indoor coil that wasn’t designed for it will run at reduced efficiency and can fail early under Austin’s summer heat load. The coil and condenser are matched components, and mismatching them also voids the manufacturer’s warranty. If you’re replacing the condenser, replace the coil at the same time. The combined cost is already built into the $3,500 to $7,500 range we quote for central air installation in Austin.
Because your system is almost certainly a single zone with one thermostat, and heat rises. The downstairs reaches the set temperature and the system shuts off, leaving the upstairs bedrooms 8 to 12 degrees warmer. The lasting fix is zoning: adding motorized dampers and a second thermostat so the upstairs gets its own cooling call. We install zoned systems in Northwest Hills and other 1970s Austin subdivisions regularly, and it typically adds $1,500 to $3,000 to the total install cost, depending on access.
