AC installation in Dallas, TX typically costs $3,500 – $7,500 for a complete system, and a properly sized and installed unit is the single biggest factor in how comfortable your home stays through July and August. We’re Cold Harbour Heating and Air Dallas, and we’ve been installing and servicing residential air conditioning across the metro since 2003. Victor Mancini leads our team with a simple rule: no surprises. The written price you get before the work starts is the price you pay, and every installation is backed by our 365-Day Done Right Promise. If your new AC doesn’t perform the way we said it would, we come back and make it right at no charge. Call (430) 213-5796 for a free, no-pressure estimate.
Furnace Installation
Furnace Installation means replacing or first-installing the gas or electric heating unit that pushes warm air through your home’s ducts, and in Dallas it usually runs $3,500 – $7,500 depending on furnace size, efficiency rating, and whether any duct modification is needed. A furnace that’s over 15 years old, makes banging noises on startup, or keeps short-cycling (turning on and off every few minutes) is often a candidate for replacement rather than repair. Cold Harbour Heating and Air Dallas sends a technician who sizes the unit to your floor plan, checks your ductwork, and hands you the written price before any work begins.
Sizing and Efficiency
Most Dallas homes need a furnace matched to their AC tonnage, not a one-size-fits-all box. We perform a load calculation that accounts for your square footage, insulation, and window exposure, then recommend an efficiency rating (80%, 92%, or 96% AFUE) that makes sense for how often your heat actually runs. On a Dallas winter, that calculation saves money on both the install and the utility bill.
Replacement Timing
The best time to schedule a furnace installation in Dallas is before the first cold snap, when technicians aren’t running emergency calls and you have time to weigh options. We keep common sizes in local supply houses, which means most replacements happen within three to five business days of your approved quote. Every install includes a written guarantee, and the Kingswell Way applies: price before work, clean job site, guarantee on paper.
Styles & brands we work with
HVAC Installation
HVAC Installation is a full-system job that pairs a new furnace (heating) with a new air conditioner (cooling), and a complete Dallas system typically runs $5,000 – $7,500 when both units are replaced together. Homeowners who replace both at once get a matched system that runs more efficiently, and they avoid the cost of two separate labor visits. Cold Harbour Heating and Air Dallas handles the entire job under one roof: sizing, installation, duct inspection, refrigerant charge, and startup testing on both units.
Why Replace Both Together
A furnace and AC share the same blower, coil, and thermostat, so mixing a 15-year-old furnace with a new AC creates mismatches that show up as poor airflow or humidity problems. Replacing both means the indoor coil is rated for the new outdoor unit’s refrigerant and efficiency level. It also means one written quote, one install date, and one team accountable for the whole system.
System Planning and Timeline
Most full HVAC installations in Dallas take one to two working days depending on the crawlspace or attic access and the condition of the existing duct connections. Before we quote anything, a technician walks the property, listens to what’s been going wrong, and puts the scope of work in writing. If you want to compare options side by side, our quote shows the difference clearly so you never have to guess.
Heat Pump Installation
Heat Pump Installation is the installation of a single outdoor unit that both cools and heats your home by moving heat rather than burning fuel, and in Dallas the job typically runs $5,000 – $7,500 for a complete ducted system. A heat pump works best in North Texas because our winters rarely dip below freezing for long, which is exactly the operating window where a heat pump is most efficient. Cold Harbour Heating and Air Dallas installs both standard and cold-climate-rated heat pumps, calculates the correct size for your home, and walks you through the actual utility math.
Heating and Cooling in One Unit
A heat pump replaces your AC and takes over most of the heating load from your furnace, which means one system to service instead of two. In a Dallas summer it works exactly like an air conditioner, and in winter it reverses to pull heat from outside air into your home. For homes with an existing furnace, we often install a hybrid setup that uses the heat pump down to about 35 degrees, then lets the furnace take over.
Incentives and Rebates
Many current heat pump models qualify for federal tax credits and local utility rebates, and our team fills out the paperwork for you at no extra charge. We’ll show you exactly which rebate applies to the unit you chose, plus the rough payback timeline based on your current electric and gas rates. That is part of the Kingswell Way: the price and the paperwork are all in writing before the install begins.
Ductless Mini Split Installation
Ductless Mini Split Installation is the process of mounting a small indoor air handler on the wall or ceiling and connecting it by a thin line to an outdoor condenser, and AC Installation - Irving and nearby Dallas areas for a typical single-zone run $3,500 – $7,500 depending on how many zones and the complexity of the line run. Mini splits make sense for add-on rooms, garage conversions, sunrooms, or older homes without ductwork. Cold Harbour Heating and Air Dallas installs single-zone and multi-zone systems and makes sure the line sets are sealed and the condensate drains are run to code.
Rooms Without Ducts
A ductless mini split gives you true zone control: each indoor unit has its own thermostat, so you aren’t cooling the whole house to make one room comfortable. These systems run quieter than window units and don’t block a window or invite the same air leakage. For Dallas homeowners with a converted garage or upstairs bonus room that never cools, this is often the most direct fix.
Install Differences to Know
We run the refrigerant lines through a small wall opening, install the outdoor condenser on a pad or wall bracket, and finish with a weather-tight line cover that matches the home. The job usually takes four to eight hours for a single zone, and we vacuum-test the line set before releasing refrigerant. Every mini split we install is charged to the manufacturer’s exact specification, not guessed at.
AC Replacement
AC Replacement is the removal of an old or failed air conditioning unit and the installation of a new one, and in Dallas it typically runs $3,500 – $7,500 depending on tonnage, efficiency (SEER rating), and whether the indoor coil must be changed. A replacement is usually the right call when the compressor fails on a unit over 10 years old, when you’re facing a refrigerant type (R-22) that’s no longer produced, or when repair costs are climbing past $650 on a regular basis. Cold Harbour Heating and Air Dallas handles the whole switch: proper removal, disposal, new unit startup, and written warranty coverage.
When to Replace, Not Repair
The National Association of Home Builders puts a central AC lifespan at 10 – 15 years, and our own service history in Dallas matches that closely. If your system is over a decade old and the compressor or condenser coil fails, the repair usually doesn’t make financial sense because the rest of the unit still carries the same age. We’ll show you the repair cost and the replacement cost side by side, in writing, and let you decide without pressure.
What Replacement Includes
Our replacement quotes include the new outdoor and indoor equipment, a new line set where required, a proper vacuum and leak check, and full startup testing of pressures, temperatures, and airflow. The written quote also covers the refrigerant charge if any additional is needed during startup. Before we leave, we walk the job with you so there are no unanswered questions.
Central Air Conditioning Installation
Central Air Conditioning Installation is the design and installation of a whole-home cooling system that distributes air through ducts to every room, and in Dallas AC Installation pricing for the typical job runs $3,500 – $7,500 depending on home square footage and SEER rating. This is the right system for homes that already have ductwork and want even, consistent cooling with one thermostat controlling the whole house. Cold Harbour Heating and Air Dallas installs complete central AC systems on all major brands and performs the load calculation before recommending any equipment size.
Ductwork and Airflow
Your current duct system plays a bigger role in the final result than most homeowners realize. Before we install a new central air conditioner, we inspect the return and supply capacity and look for gaps or crushed runs that would starve the new unit of airflow. If duct fixes are needed, our written estimate includes them as separate line items so you see exactly where the money goes.
SEER and Long-Term Costs
A higher SEER rating means better energy efficiency, and in Dallas a 16 SEER unit will generally cost more upfront but run noticeably cheaper than a 14 SEER unit over a Texas summer. We lay out the real difference in dollars so you can choose based on how long you plan to stay in the home. The number is on the written quote before you approve anything.
Brands We Service
Trane units are known for their build quality and long parts availability, and our technicians have installed and serviced Trane systems across Dallas for over twenty years. We stock factory-approved Trane parts and follow Trane’s published installation and charging procedures, so the new unit starts up exactly as it left the factory. If you have a Trane that needs replacement, we can typically match a new Trane model to your existing footprint without major duct or line set changes.
Goodman is one of the most common brands in Dallas homes because it offers a strong value proposition at a lower upfront price. Our team works with Goodman equipment regularly and knows its installation tolerances and warranty registration steps. For homeowners who want a dependable system without a premium-brand price, a Goodman central AC or heat pump is often the most practical choice. Whether you have Goodman, Rheem, or any other make, we can install and service your system.

- The outdoor unit runs but the air inside isn’t cold. This often means a refrigerant leak or a burnt compressor contactor, and running the system longer only adds to the utility bill. A trained technician can find the issue and quote the fix in writing before any work begins.
- Your energy bills jumped noticeably from one summer to the next. A system that has lost refrigerant or a failing run capacitor runs far more hours to hold the same temperature. If the bill is up 20% or more, something in the system is working harder than it should.
- The unit is over 12 years old and needs a repair over $500. At that age, more failures tend to follow. We can show you the repair cost and a full replacement quote side by side in writing, so the math is yours to make.
- The thermostat says it’s colder than the air in the room actually feels. That gap between setpoint and actual room temperature can point to duct leaks, a dying compressor, or an oversized system that short-cycles. Any of those problems will run your equipment into the ground early.
- The system made a loud bang, pop, or grinding noise and then stopped. A failed compressor or a seized blower motor usually announces itself once and then goes silent. Don’t try to restart it: call (430) 213-5796 and we’ll send a technician to inspect it safely.
Our Process, Step by Step
- 1
Call and book a visit. A real person answers the phone 24 hours a day, seven days a week at Cold Harbour Heating and Air Dallas. We’ll set a firm arrival window that same week, not a four-hour spread, and our technician will arrive in a clean, marked van.
- 2
We measure and inspect, not guess. The technician walks every relevant part of the job: square footage, insulation, window orientation, existing equipment, duct condition, and electrical load. We use a room-by-room load calculation rather than a rule-of-thumb guess, because an undersized or oversized unit never works right in Dallas humidity.
- 3
You get a written price. Before any tool comes out, we hand you a line-item quote that includes equipment, labor, ductwork if needed, and whatever else the job requires. That number does not change at the door. The Kingswell Way says the price before the work, and we’ve been doing it that way since 2003.
- 4
We install to manufacturer spec. Our technicians are trained on nine major residential brands including Trane, Lennox, and Goodman. We nitrogen-pressure test the line set, pull a deep vacuum, and release refrigerant to the exact ounce the manufacturer specifies. No shortcuts, no “good enough.”
- 5
We test the system and clean the site. After startup, we run the full cooling cycle and check pressures, temperature drop, and airflow. We leave the work area cleaner than we found it, show you the written 365-Day Done Right Promise, and answer every question before we leave.
How Much Does AC Installation Cost in Dallas?
A typical AC Installation in Dallas runs $3,500 – $7,500, and the spread comes down to a few specific factors you should know before you get quotes. A 2-ton, 14 SEER replacement for a modest 1,200 – 1,500 square foot home sits at the lower end near $3,500 – $4,500. A 4-ton, 16 SEER system for a larger two-story home, or any job requiring duct modification or a new line set, pushes the number toward $5,500 – $7,500. If you’re replacing both the furnace and the AC together, you should expect the combined number to land near the middle-to-top of that same range rather than doubling it.
What actually moves the price: tonnage (bigger homes need bigger units), SEER rating (higher efficiency costs more upfront), accessibility (attic installs run more in labor than ground-level pads), and whether your existing duct and electrical are suited to the new equipment. You avoid overpaying by getting a written line-item quote and by refusing any company that gives only a single number over the phone without visiting the home. Our written estimates include equipment, labor, disposal, startup testing, and any required permit fees, and they never change at the door.
