AC installation in Addison typically runs $3,500 – $7,500 for a complete system, and the real question isn’t price. It’s whether the crew knows Addison’s older homes well enough to catch what a like-for-like swap misses: undersized duct static, a corroded attic air handler, an electrical panel that can’t carry the load. We do. Cold Harbour Heating and Air Dallas has been answering phones in the DFW area since 2003, and our crews know Addison’s Greenhill, Midway corridor, and Belt Line Road homes block by block. Call (430) 213-5796 for a written quote before any work begins.
Why Cold Harbour Heating and Air Dallas Is Addison’s Preferred AC Installation Company
Addison homeowners call us after another company disappoints them. That’s the honest pattern. They had a no-show, a price that jumped at the door, or a repair that quit within a month. We’re built to answer that. Every installation we do in Addison starts with a written price handed to you before a single tool comes out. That price doesn’t change at the door. It’s 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, come back if it fails.
Our technicians are background-checked and uniformed, trained to service nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

Styles & brands we work with






Furnace Installation in Addison
Furnace installation in Addison is a job we approach differently than the typical swap. Addison’s single-family homes, built mostly from the 1960s through the 1980s, often have the original furnace cabinet tucked into a tight closet or narrow attic chase. The new high-efficiency furnaces are larger and need more airflow than those old units delivered. A proper furnace installation in Addison runs $3,500 – $7,500, and that includes the load calculation, sheet metal transition work, gas line verification, and full startup testing.
Furnace and AC Pairing on Original Ductwork
When we install a furnace alongside a new AC system, we check the duct static pressure. Addison’s original slab-duct runs were sized for low-efficiency blowers. Modern systems push more air, but the ducts haven’t changed since the Carter administration. We measure and correct before we finish the job.
What a Written Furnace Quote Includes in Addison
Your written quote covers the equipment, the transition work, the electrical, the gas, and the startup. No surprises at the door. That’s the whole point of the Kingswell Way. You’ll know the exact price before we start, and it’s the exact price you’ll pay when we leave.
HVAC Installation in Addison
HVAC installation in Addison means replacing both the cooling and heating sides together, and for many of the 1970s and 1980s homes here, that’s the smart move. These systems were installed as matched pairs. When you replace only the AC and leave a 25-year-old furnace blower doing the work, you ask a tired motor to move air for a system it was never sized for. A complete HVAC installation in Addison runs $3,500 – $7,500, depending on efficiency level and the duct modifications required.
Duct Static on Slab Foundation Homes
Slab-foundation homes in Addison carry their ductwork in concrete channels. Replacing that ductwork isn’t practical, so we focus on static pressure correction. A high-static system burns out blower motors. We measure, quote the fix, and install it so the system works the way the manufacturer rated it.
Why a Like-for-Like Swap Usually Disappoints in an Older House
Here’s the thing we tell every Addison homeowner who asks for a simple swap: the old 2.5-ton unit was probably the wrong size to begin with. Contractors in the 1970s often sized equipment by square footage only, ignoring the unbalanced floor plan, the original single-pane windows, and the cathedral ceilings some Addison homes have. Swapping in a new 2.5-ton unit without a load calculation means short-cycling that never clears humidity and a house that still feels sticky. We run the load calculation first, then install.
Trusted Brands We Service in Addison
We install and service the equipment Addison homeowners already know: Carrier, Bryant, American Standard, Daikin, and more. When you schedule an installation, we arrive with the equipment ordered to your home’s specific size and efficiency requirements, not whatever happens to be on a warehouse shelf. Our Dallas-Fort Worth dispatch coordinates Addison crews so the Brand you choose is available on schedule. We stand behind every brand we install with the same 365-Day Done Right Promise, written down, every time.

AfterCommon AC Installation Problems We See in Addison Homes
- Undersized duct static on original slab-duct runs: The new blower motor fights the old ducts and burns out within a season. We measure static pressure before we ever order equipment.
- Rusted first-generation attic air handlers in Greenhill: Decades of condensation have eaten the evaporator coil and left the blower motor on borrowed time. A like-for-like swap won’t fix it; the chassis and coil both need replacing.
- Electrical panels that can’t carry a modern system: A 1970s Addison panel with a 30-amp breaker will trip the first time the new system pulls full load on a 100°F afternoon. We check panel capacity before installation and quote any needed upgrade in writing.
- Humidity control failures from oversized units: An oversized system cools the air too fast and shuts off before it dehumidifies. Addison’s high dew points make this worse. The house feels cold and clammy at the same time.

FAQs About AC Installation in Addison
Because June is when the first sustained 100°F heat spike hits, and that’s exactly when a worn-out blower motor or a rusted evaporator coil finally gives out. In Addison’s Greenhill area especially, the original 1970s attic air handlers have been condensing for decades. The first triple-digit stretch after a mild spring is the stress test. If your system survived last August but won’t cool in June, the components are likely on their last season. Call us at (430) 213-5796 and we’ll send a technician to check what’s failing before it quits entirely.
You can, but you shouldn’t. A like-for-like swap on a 1978 Greenhill home usually repeats whatever sizing mistake was made originally. The old 2.5-ton unit was probably sized by square footage alone, without a load calculation, and it never handled humidity well. A new 2.5-ton unit on the same original slab-duct runs will short-cycle and leave the house clammy. Before any equipment gets ordered, we run a proper load calculation on your exact floor plan, window orientation, and duct condition. That’s how you get a system that actually works. Call (430) 213-5796 to schedule the load calculation first.
Maybe not, and this is one of the most common surprises we find in Addison’s 1960s and 1970s homes. The original panels were often built with a 30-amp breaker for the AC circuit. Modern systems, especially higher-SEER2 units with ECM blower motors, can pull enough at startup to trip that breaker on the first 100°F afternoon. We check panel capacity before installation and include any needed electrical upgrade in your written quote. No surprises at the door. Call (430) 213-5796 for the exact verification on your home.
SEER2 is the newer efficiency rating standard that took effect in 2023, and it measures real-world performance more accurately than the old SEER number. A unit rated 14 SEER under the old system might be rated 13.4 SEER2 now. For an Addison homeowner, the practical difference is that SEER2 ratings give you a truer picture of what the system will actually do in our hot, humid summers. When we quote a system, we show you both numbers and explain what each means for your monthly cooling bill. Call (430) 213-5796 and we’ll walk you through the options in plain English.
Yes, and this is a common constraint in Addison’s 1960s and 1970s homes, where attics were framed for smaller equipment. We install compact horizontal air handlers designed to fit tight attic spaces, and we’ve used them on several Greenhill homes where the original vertical unit simply won’t accommodate a modern replacement. We also look at whether a ducted mini-split or a slim-profile unit could work better for your specific attic dimensions. Call (430) 213-5796 and we’ll measure your attic space in person and show you what fits.
