AfterFast, Reliable AC Installation Across Argyle
Most AC Installation projects in Argyle run between $3,500 and $7,500, with the final price depending on your home’s conditioned square footage, whether the existing ductwork can handle the load, and whether you need a single-zone system or a multi-zone layout to cover finished spaces the original builder never counted. Our AC Installation team designs every system from a fresh Manual J load calculation rather than swapping like-for-like equipment that was probably undersized from day one.
We’re familiar with Argyle’s shift from rural Denton County ranch land to the high-end bedroom community it is now. That means we pull permits knowing Denton County requirements, we size equipment for the actual conditioned space including those post-build bonus rooms, and we dispatch crews who understand that a Harvest home off Old Justin Road needs a different approach than a pre-boom ranch property on propane. Our scheduling runs from the Dallas-Fort Worth office, and we keep dedicated install slots open for Argyle homeowners because July afternoons here don’t forgive a system that can’t hold setpoint.

Why Coldharbour Heating & Air Is Argyle’s Preferred AC Installation Company
We’ve been serving the Argyle area since 2003 as an independently owned and operated member of the Kingswell network, and our reputation here was built one written guarantee at a time. Homeowners in Harvest, Canyon Falls, and the older ranch parcels off FM 407 know our technicians by the uniform and the fact that we show up in the window we promised, not “sometime between 8 and 5.”
Our 365-Day Done Right Promise applies to every repair we perform, and that same rigor carries into every AC Installation we design. If a repair fails within 365 days, we come back and correct it at no charge, with that guarantee written down before the technician leaves. No verbal handshakes, no conditions buried in fine print.
Phones are answered by a live person 24 hours a day, 7 days a week. When you’re staring at a dead builder-grade system in August and the upstairs game room is hitting 85°F, you don’t want voicemail. You want a human who can get a crew to Argyle.
Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whatever system is in your home, the technician who shows up can work on it.
Furnace Installation in Argyle
Furnace Installation in Argyle covers both natural gas and propane-fired systems, and the job starts with understanding what fuel your property actually has access to. Many newer master-planned communities in Argyle have city gas, but plenty of older rural parcels and some outlying lots never got lines, leaving homeowners on propane tanks or all-electric package units. A typical Furnace Installation in Argyle falls within our $3,500-$7,500 range, with propane conversions and venting modifications adding complexity that we price upfront in writing.
Propane and All-Electric Properties
Homes without natural gas lines need furnaces rated for propane, with proper burner orifice changes and gas pressure adjustments. We handle the conversion specs and coordinate with your propane supplier so the system fires correctly on day one. This is common enough in Argyle that our trucks carry propane conversion kits for the brands we install.
Sizing for Argyle’s Cold Snaps
The February 2021 ice storm proved that North Texas winter design temperatures aren’t theoretical. We size furnaces for the actual heat loss of your home, not a rule-of-thumb based on square footage alone. A 6,000 sq ft custom home with tall ceilings and lots of glass needs more than double the output of a 2,500 sq ft ranch, and we calculate that precisely.
HVAC Installation in Argyle
HVAC Installation in Argyle is rarely a simple equipment swap because the housing stock here creates design problems that didn’t exist when the original system was spec’d. The dominant post-2010 custom and semi-custom construction on half-acre or larger lots routinely includes 3,500-6,000 sq ft of conditioned space, with floor plans so large that equipment selection errors compound quickly. A typical HVAC Installation in Argyle runs $3,500-$7,500, with multi-zone systems and mini split supplements toward the higher end of that range.
Multi-Zone Design for Large Custom Homes
Single-zone systems in 5,000+ sq ft homes create perpetual hot spots and cold spots. We design zoned systems with multiple air handlers or dampers, each controlled independently, so the upstairs game room and the main living area don’t fight over one thermostat. This requires proper duct sizing and static pressure balancing, not just adding a second thermostat.
Commissioning What the Builder Skipped
Many Argyle homes were never commissioned properly. We verify refrigerant charge, measure static pressure across the duct system, and calibrate each thermostat against actual supply air temperature. The SEER2 rating on the box only shows up at the register if the installation is dialed in correctly. We do that dialing before we leave.
Trusted Brands We Service in Argyle
Our technicians are trained to install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Argyle homeowners, that means we stock common parts locally and can source warranty components without the multi-week delays that plague contractors who only work with one or two brands. We install Rheem and York systems regularly for their balance of efficiency and durability in North Texas conditions, and we’ve had strong results with Daikin and Bryant equipment for the variable-speed multi-zone layouts that Argyle’s larger homes increasingly need. If you have a preference, we’ll source it. If you don’t, we’ll recommend based on your home’s actual load calculation and your budget, with the written price in hand before any work begins.
Common AC Installation Problems We See in Argyle Homes
- Builder-spec tonnage sized for the base floor plan only. The original HVAC sub calculated for the marketed square footage, then the homeowner finished the bonus room, conditioned the third garage bay, and added a game room upstairs. The 5-ton system is now trying to cool 6,000 sq ft with the capacity for 4,000. We see this constantly in Harvest and Canyon Falls.
- Multi-zone systems installed without proper commissioning. A high-SEER2 variable-speed system can actually perform worse than basic equipment if static pressure is wrong, refrigerant charge is off, or dampers are unbalanced. The efficiency number on the EnergyGuide label is a laboratory result; the number at your register depends on the quality of the install.
- Expansive clay soils stressing line sets and duct connections. Argyle’s Cross Timbers clay shifts seasonally with moisture changes. We’ve found refrigerant leaks at the foundation penetration and duct separations in crawl spaces that a quick install missed entirely. Our installations include post-settling inspection recommendations.
- Post-build conditioned spaces left on the original single zone. The upstairs bonus room was finished after closing, but the thermostat is downstairs in the foyer. That room never gets enough cooling in July. We regularly retrofit ductless mini-splits into these spaces rather than forcing the main system to do work it was never designed for.
Pricing for AC Installation in Argyle, TX
| Service | Typical Range in Argyle |
|---|---|
| AC Installation (central air, single-zone) | $3,500-$5,500 |
| AC Installation (multi-zone or large custom home) | $5,000-$7,500 |
| Mini split addition (single zone, post-build space) | $3,500-$5,500 |
| Full system with duct modifications | $5,500-$7,500 |
What moves a job toward the higher end: multi-zone design, ductwork modifications or replacements, electrical panel upgrades, propane conversion kits, and homes over 4,500 sq ft that need two systems or a large single unit with extensive zoning. What keeps it lower: straight replacement of existing properly sized equipment with accessible ductwork and adequate electrical service.
We provide a written, fixed price before any work begins. That price does not change at the door. Estimates are free, and we’ll walk through your home, measure the actual conditioned space, and explain what we’re proposing before you decide.

FAQs About AC Installation in Argyle
No, one system is almost certainly undersized if your 5,000 sq ft includes finished bonus rooms, a game room, or a conditioned garage bay that weren’t in the original load calculation. We replaced a 5-ton builder-grade system in a Harvest home off Old Justin Road with a 3-zone Carrier variable-speed setup after our load calculation showed the original single-zone design was short by nearly two tons once the finished game room and conditioned third bay were included. We also ran a dedicated mini split for the bonus room, then commissioned the whole system - verified refrigerant charge, static pressure, and thermostat calibration across each zone - before the July heat hit. The upstairs had never held setpoint in prior summers; this year it did without a single call back. Call (817) 402-2972 and we’ll measure your actual conditioned load.
Because the SEER2 rating is a laboratory measurement, and real-world efficiency depends on installation quality. If static pressure isn’t balanced, refrigerant charge isn’t verified, and dampers aren’t calibrated, the system short-cycles, humidity stays high, and your electric bill doesn’t drop the way the yellow tag promised. We commission every installation: measure airflow at each register, verify charge with subcooling and superheat, and document static pressure across the duct system. The number on the box only matters if the work in your attic matches it. Call (817) 402-2972 for a free estimate and we’ll show you what proper commissioning looks like.
Yes, we install both heat pumps and propane-fired furnaces for Argyle properties without natural gas lines, which includes many older rural parcels and some outlying lots in master-planned developments where gas mains haven’t reached. Heat pumps work well for most of Argyle’s heating season, though we size backup heat strips for the occasional single-digit night. For propane, we specify conversion-ready furnaces and coordinate with your tank provider for proper gas pressure at the burner. Call (817) 402-2972 and we’ll walk through which option fits your property and fuel situation.
Yes, and it’s often the right solution for post-build conditioned spaces that the original system never accounted for. In Argyle’s newer custom-home subdivisions, three-car garages and upstairs game rooms are frequently conditioned as afterthoughts, leaving the original single zoned system chronically short. A ductless mini split gives that space its own zone and thermostat without forcing your main system to run overtime trying to cool square footage it wasn’t sized for. Typical mini split additions in Argyle fall in the $3,500-$5,500 range. Call (817) 402-2972 for a free estimate.
Argyle sits on expansive Cross Timbers clay that swells when wet and shrinks when dry, which stresses refrigerant line sets and duct connections where they penetrate the foundation or run through crawl spaces. We’ve found leaks and separations that developed months after installation because the settling wasn’t anticipated. Our installations include proper line set support, flexible connections where appropriate, and a post-installation inspection schedule to catch movement before it causes charge loss or airflow problems. Call (817) 402-2972 and we’ll include soil-specific protections in your written proposal.
