What Does AC Replacement Cost?

The Real Cost Range for AC Replacement

A whole-house AC replacement in this area usually falls between $5,500 and $13,000. That’s a wide window because two homes on the same street can need very different systems. Most jobs we run, a standard swap using your existing connections with no major rework, land in the $7,000 to $10,000 range. That covers the equipment and materials, the install labor, standard connections, startup and testing, and hauling away your old unit.

What pushes a job toward the higher end? Mostly system size and efficiency. A bigger house needs more tonnage. And a higher SEER2 rating on the new unit costs more up front. It usually runs cheaper month to month, though. Brand and model matter too. Access plays a real role; if your unit sits in a tight attic space or a hard-to-reach exterior spot, labor time goes up. The condition of your existing ductwork, wiring, or plumbing connections can also add cost if any of it needs modification to meet current code.

Here’s what a lot of quotes leave out. Duct, electrical, or plumbing modifications aren’t included in that base range. Neither are code corrections or permit fees. We flag those during your consultation. If your attic ductwork is undersized for a new system, or your electrical disconnect needs updating, that’s a separate line item. We’ll walk you through it before we touch anything. We’d rather tell you that up front than let it show up as a surprise on the invoice.

If you’re not sure whether your situation is a straightforward swap or something more involved, our AC replacement service starts with a cooling load calculation and a walkthrough. The number you get is the number you pay.

• Included in the price: equipment and materials, install labor, standard connections, startup and testing, and haul-away of your old unit
• Not included unless stated: duct, electrical, or plumbing modifications, code corrections, and permits
• Service-call fee: $26 to $99, credited toward the job if you move forward with us
• Financing available on qualifying installations, on approved credit

What Drives Your AC Replacement Price Up or Down

A like-for-like AC replacement using your existing connections usually lands between $7,000 and $10,000. The bigger range, $5,500 to $13,000, covers everything from a straightforward swap to a job with real complications. What pushes a quote toward either end comes down to a handful of specific things we look at during the consultation.

• System size and capacity. A unit sized wrong for your square footage either short-cycles or runs constantly. We run a cooling load calculation instead of guessing.
• Efficiency rating. Higher SEER2 equipment costs more upfront but pulls less power. In Sunnyvale summers, that difference shows up on your monthly electric bill fast.
• Brand and model. Trane systems, including high-efficiency and variable-speed models, sit at a different price point than base equipment.
• Access to the unit. A condenser tucked behind a fence or an attic-mounted air handler with tight clearance takes longer to remove and set. An open slab pad is much easier.
• Condition of existing ductwork and wiring. A lot of the slab-on-grade homes we work on around Dallas County were built decades before today’s code. The ductwork wasn’t sized for a modern high-efficiency system.
• Code upgrades and permits. If your electrical disconnect or line set doesn’t meet current code, that gets corrected as part of the job.
• Custom fabrication. Odd closet dimensions or a non-standard plenum sometimes need sheet metal work built to fit.

Your quote includes the equipment, install labor, standard connections, startup and testing, and hauling away your old unit. It does not include duct, electrical, or plumbing modifications, code corrections, or permits unless we spell those out in writing first. Most of the range you’ll see quoted anywhere comes from ductwork and access, not the equipment itself.

We won’t know which of these apply to your home until someone’s looked at your system in person. That’s part of our process. No guessing over the phone. No number that changes once the crew shows up. We measure the space, check the attic or closet access, look at the age of your ductwork, and write the price down before anything gets touched.

What’s Included in Our AC Replacement Price – and What’s Not

When we quote you for our AC replacement service, the number covers the whole job, not just the box on your slab. That includes the new equipment and materials, the install labor, standard connections to your existing lines, startup and testing once it’s running, and hauling away your old unit. You’re not left with a dead condenser sitting in your yard.

• New equipment and installation materials
• Installation labor by a licensed technician
• Standard connections using your existing lines
• System startup and testing before we call it done
• Haul-away of your old unit

Here’s where it depends. Your quote does not include duct, electrical, or plumbing modifications, code corrections, or permit fees. That is, unless we’ve written them into the price up front. A lot of homes in Sunnyvale and the surrounding DFW towns were built decades ago. What’s behind the wall or in the attic doesn’t always match what a new system needs.

We’ve opened up plenty of attics on 1970s and 80s slab homes. The ductwork was undersized for the tonnage the house needs. Or the electrical disconnect box was never grounded to current code. When that happens, it’s the house telling us what it needs to run safely and efficiently. We’ll show you exactly what we found before we touch it.

Code corrections come up more with older homes and less with newer subdivisions. But we don’t assume either way. That’s part of why our AC replacement service starts with a real inspection, not a phone estimate. We look at your ductwork, your electrical connection, and your attic access before we hand you a number. Guessing at that stuff is how homeowners end up with surprise charges mid-job.

If a modification is needed, we’ll price it separately. We get your approval before any work starts. Nothing gets added to the job without you seeing it and signing off first. On larger installations, financing is available on approved credit. That helps if you’d rather spread the cost out instead of paying it all at once.

The short version: the equipment, labor, and startup are locked into your quote. Anything your home’s existing wiring or ductwork requires beyond that gets identified during the inspection. And it’s priced on its own, in writing, before we start.

The Most Common AC Replacement Job and What It Runs

Most AC replacements we do across the Sunnyvale and DFW area run between $5,500 and $13,000. The job we see the most, a standard like-for-like swap using your home’s existing electrical and refrigerant line connections, usually lands between $7,000 and $10,000. That covers the new equipment, install labor, startup, testing, and hauling away your old unit.

The number moves based on a handful of real factors, not guesswork. Equipment size and efficiency rating (SEER2), brand and model, and how easy the unit is to access all change labor time and cost. So does the condition of your existing ductwork or wiring. A slab home in an older Mesquite subdivision with attic ductwork from the 1970s or 80s is a different job than a newer home in a Forney subdivision with ducts that were sized correctly the first time.

• Included: equipment and materials, install labor, standard connections, startup and testing, and haul-away of your old unit
• Not included: duct, electrical, or plumbing modifications, code corrections, or permits unless we’ve specifically quoted them

That second list matters more than it sounds like. If your ductwork needs rework to handle a new system’s airflow, or your electrical panel needs an upgrade to support it, that’s a separate line item. We’ll walk you through it before we touch anything. It won’t be a surprise on the invoice. We’d rather tell you that up front than let you find out at the end.

If you’re not sure yet whether replacement is the right call versus a repair, our AC replacement page walks through how we help homeowners weigh that decision.

A diagnostic or estimate visit runs $26 to $99 as a service-call fee. That fee gets credited toward the job if you move forward with us. Financing is available on qualifying installations for homeowners who’d rather spread the cost out than pay it all at once.

What Our Service Call Fee Covers

Before you get a number for a full AC replacement, a technician has to come look at your system in person. That visit runs $26 to $99. It’s credited toward the job if you decide to move forward with us. Nobody can size a system, spot ductwork problems, or hand you a real number over the phone.

Here’s what happens during that visit. A licensed technician inspects your current system. They check how your ductwork is set up. They also look at things like attic access and electrical connections. We do a cooling load calculation so the new system is sized right for your square footage, not just swapped one-for-one. Then we walk you through what we found in plain language – no jargon – before anything gets written down.

If replacement is the right call, that visit turns into a written, flat-rate quote before we touch anything. You’ll see the total price up front, what’s included, and what isn’t. If it turns out your system just needs a repair instead of a full replacement, we’ll tell you that too. Nobody here pushes a replacement on a unit that has years left in it.

• In-person inspection of your current AC system and ductwork
• A cooling load calculation to size the new system correctly
• A plain-English explanation of what we found and why it matters
• A written, flat-rate replacement quote before any work is approved

One thing worth knowing going in: the fee gets credited toward the job. But it’s not refunded if you decide not to move forward at all. That’s the tradeoff for a real technician showing up and doing real work instead of guessing over the phone. You can get more detail on what drives the total cost on our AC replacement page before you schedule anything.
