Furnace Installation

Furnace Installation is what we do when an Austin home’s heating system has reached the end of its service life, usually between 15 and 20 years, and repairing it no longer makes financial sense. Cold Harbour Heating and Air Austin handles complete furnace replacement from load calculation to final inspection, and the work typically falls in the $3,500 to $7,500 range depending on furnace efficiency rating, fuel type, and whether ductwork modifications are required.

When a furnace replacement makes sense

If your furnace needs a third repair in two winters, or the heat exchanger has failed, replacement is usually the honest answer. Austin’s cold snaps are short but real, and a failing furnace tends to quit on the coldest night of the year. We help you weigh repair dollars against the cost of a new system without pushing you either way.

Efficiency ratings and Austin’s climate

Austin winters don’t demand the extreme high-efficiency furnaces you’d find in Minnesota, but an 80% AFUE unit still costs more to run than a 95% model over a decade. Our technicians explain the payback math in plain terms so you can decide what’s worth it for your house and your budget.

HVAC Installation

HVAC Installation covers the full heating and cooling package, pairing a new air conditioner with a matched furnace or air handler so the entire system starts fresh on the same day. Cold Harbour Heating and Air Austin installs complete HVAC systems with a written price before work begins, and most full-system installs in the Austin area land between $3,500 and $7,500 depending on home size and equipment tier.

Full system replacement vs. single component

If your AC condenser is 12 years old and your furnace is 14, replacing just one piece often leaves you with a mismatched system that strains itself and shortens its own life. A matched HVAC installation runs quieter, cools more evenly, and typically costs less in energy than a patchwork of old and new components.

Why matching matters for efficiency

Modern AC condensers are designed to talk to specific blowers and coils, and mixing brands or generations can knock 10 to 15 percent off the system’s rated efficiency. We verify that every component we install is rated to work together, so the SEER number on the box is the efficiency you’ll actually get in your Austin home.

Heat Pump Installation

Heat Pump Installation gives an Austin homeowner a single system that both cools in summer and heats in winter, which is why heat pumps have become common across Central Texas. Cold Harbour Heating and Air Austin installs heat pump systems in the $3,500 to $7,500 range for most homes, with a written quote upfront and a firm installation date before any equipment is ordered.

How a heat pump handles Austin’s weather

Heat pumps are built for exactly the kind of climate Austin has: long, hot summers and short, mild winters. Because a heat pump moves heat rather than burning fuel, it’s often the lowest-operating-cost option for homes in neighborhoods like Jollyville and Wells Branch that don’t already have gas lines run to the house.

Cold-weather performance in Central Texas

The old knock on heat pumps was that they couldn’t keep up in real cold, but modern units hold their efficiency down into the 20s, which covers nearly every night Austin ever sees. For the rare hard freeze, most of our Austin installations include a backup heat strip that handles the handful of below-freezing hours without breaking a sweat.

Ductless Mini Split Installation

Ductless Mini Split Installation puts cooling and heating exactly where you need it, room by room, without running ductwork through walls and ceilings that were never designed for it. Cold Harbour Heating and Air Austin installs ductless mini split systems for older Austin homes, garage apartments, and room additions, with typical jobs running $3,500 to $7,500 depending on the number of indoor air handlers required.

Ideal for Austin’s older housing stock

Homes in areas like Hyde Park, Travis Heights, and the older streets around Lost Creek often lack central ductwork entirely, and retrofitting ducts can cost more than the cooling equipment itself. Ductless mini splits solve that problem cleanly, with a small outdoor unit serving one to five slim indoor heads mounted high on the wall or ceiling.

Zoned comfort without new ductwork

Ductless systems also solve the classic Austin problem of a finished attic or converted garage that never gets comfortable. Each indoor unit runs on its own thermostat, so a room addition over in Shady Hollow or Camp Swift can stay at 72 without freezing the rest of the house to get there.

AC Replacement

AC Replacement is the job we do most often in Austin, swapping out a worn-out condenser and matched coil for new equipment sized correctly for the house as it stands today. Cold Harbour Heating and Air Austin completes most AC replacement jobs in one day, with pricing between $3,500 and $7,500 depending on efficiency level, brand, and whether any duct sealing or line set work is needed.

Knowing when to replace rather than repair

When a compressor fails on a 12-year-old system, you’re looking at a repair bill that’s often half the cost of a new unit, with no guarantee the condenser fan motor or the coil won’t be next. We give you an honest assessment of your system’s remaining life and the real cost of keeping it alive, so you can make a decision based on numbers rather than optimism.

The Kingswell approach to AC replacement

Every AC replacement we do starts with a load calculation, not a guess based on what was there before. Austin homes have grown more airtight with new windows and insulation, and installing the same size unit on a tighter house can mean short cycling and humidity problems. Our written quote reflects the system your home actually needs today.

Central Air Conditioning Installation

Central Air Conditioning Installation is the traditional whole-house cooling approach, using a network of supply and return ducts to push conditioned air to every finished room from a single indoor air handler. Cold Harbour Heating and Air Austin installs central AC systems sized for homes from Hornsby Bend to Leander, with most installs quoted between $3,500 and $7,500 before any work begins.

New construction vs. retrofit in austin neighborhoods

For a new build in Buda or Taylor, central AC installation is straightforward and goes in before drywall. For an existing home that’s never had central air, we have to plan duct routes through attics, closets, and sometimes crawl spaces, which adds complexity we factor into the written quote up front rather than discovering at the door.

Duct quality and long-term performance

Central air conditioning is only as good as the ducts that carry it, and leaky ductwork in a hot Austin attic can waste a third of the cooling you’re paying for. On every installation we inspect existing ducts, recommend sealing or replacement where it’s needed, and quote that work in writing as part of the same fixed price.

Brands We Service

We’re factory-trained on York equipment, and we stock the common York parts that Austin heat and humidity tend to wear out first: capacitors, contactors, and condenser fan motors. Our techs also work on Daikin systems regularly, including the ductless mini splits Daikin is known for, which means we can handle warranty work on those units without referring you out. American Standard equipment is another staple of our Austin install base, and our familiarity with their air handlers and heat pumps goes back over two decades.

Whether you have a York, Daikin, American Standard, or any other make from the nine major brands we service, the technician who shows up at your door will already know your equipment. No learning on your dime.

Signs You Need a Pro Right Now

• Warm air blowing from the vents. If your AC is blowing air that’s room temperature or warmer, the compressor may have shut down or the refrigerant charge is too low to cool. Running it in this state damages the compressor further and turns a simple fix into a replacement.
• Ice forming on the refrigerant lines or coil. Ice on an AC unit in Austin summer means airflow or refrigerant problems, and it usually gets worse the longer it runs. Shut the system off and call us, because running an iced-up unit risks slugging liquid refrigerant into the compressor, the single most expensive failure an AC can have.
• A burning or oily smell when the system runs. Electrical components overheating or a refrigerant leak both produce distinct smells that shouldn’t be ignored. These symptoms can escalate from nuisance to hazard quickly, so we treat them as urgent calls when you reach us at (361) 204-1605.
• Water where it shouldn’t be. A clogged condensate drain can overflow into ceilings, walls, and flooring, and Austin’s humidity means your AC produces gallons of condensate every day. The faster that drain is cleared, the less drywall and flooring you’ll be replacing along with the AC repair.
• Short cycling that’s getting worse. If your AC turns on and off every few minutes, something is tripping a safety limit, often an overheating compressor or a failing control board. Each short cycle wears the compressor down further, and waiting usually means replacing instead of repairing.

Our Process, Step by Step

1. 1
   Phone consultation and scheduling. When you call (361) 204-1605, a live person answers regardless of the hour, asks about your system and its symptoms, and books a visit. You’ll get a firm arrival window before we hang up, not a four-hour spread you have to burn a day waiting on.
2. 2
   On-site evaluation and load calculation. The technician arrives in uniform, background-checked, and ready to measure your home rather than guess at it. We take square footage, ceiling height, window orientation, insulation levels, and recent weather data into account to determine the right system size for your Austin home.
3. 3
   Written quote, no tools out first. Before any equipment is ordered or any work begins, you’ll have a written price covering equipment, labor, materials, permits, and cleanup. That price does not change at the door. If we find something unexpected during the install, we stop and talk to you about it rather than invoicing a surprise.
4. 4
   Installation with a set date. We order your equipment, confirm the installation date in writing, and show up when we said we would. Our crews clean as they work, and when they leave, the old equipment is hauled away and the area is cleaner than when we arrived.
5. 5
   Walkthrough and written guarantee. Before the technician leaves, they walk you through the new system, show you how to work the thermostat, and hand you the written Kingswell Guarantee covering the installation. If anything about our work fails inside 365 days, we come back and make it right at no charge.
