AfterAC Replacement in Dallas, TX
AC replacement in Dallas typically costs between $4,500 and $9,800 depending on system size, efficiency rating, and ductwork condition. Most full replacements take one day, and Dalton Heating & Air Dallas provides a written price before any equipment gets ordered. If your system is over 12 years old or needs a compressor replacement, replacing the whole unit is usually the smarter financial move. Call us at (254) 280-5320 and we’ll give you a straight answer on whether repair or replacement makes sense for your house.
We’re part of Garrison Partners and have held every Dallas job to The Garrison Standard since 2003. That means the price goes in writing before work starts, the crew shows up inside the window, and the installation carries a full-year written guarantee. When you’re weighing a $6,000 decision, that discipline matters.
When You Need AC Replacement
Not every failing AC needs to be replaced. Some issues, like a Capacitor Replacement or a contactor, are under $200 fixes. These are the situations where replacement is the call we’d make if it were our own house:
- Compressor failure on a system over 10 years old. A compressor swap on an R-22 system can run $2,500 to $4,000, and you’re still left with an aging coil and condenser. In Lake Highlands and Richardson, we regularly see this exact math push homeowners toward full replacement.
- Refrigerant leaks on an R-22 system. R-22 (Freon) production stopped in 2020. The remaining supply is priced so high that a recharge often costs more than a down payment on a new R-410A or R-454B system.
- Repair costs piling up. If you’ve spent more than $2,000 on repairs over the past two years, that money would have gone further as part of a new unit with a fresh warranty.
- The system can’t hold temperature through a Dallas summer. When your AC runs nonstop from June to September and the house still sits at 80 degrees, the system is undersized or worn out. No repair fixes a unit that’s simply lost its capacity.
- Energy bills that keep climbing every August. A 12 SEER unit from 2005 uses roughly 30% more electricity than a modern 16 SEER system. In a Dallas cooling season that runs six months, that difference shows up on every bill.
- Frequent breakdowns during heat waves. If you’ve had two no-cool calls in one season, the next one is coming. We’d rather schedule a replacement on your timeline than show up at 9 PM on a 104-degree day for an emergency swap.
Our AC Replacement Process
Here’s how a replacement with Dalton Heating & Air Dallas works, step by step, for our ac repair installation services. No surprises, no “while we’re here” upsells.
- In-home assessment and load calculation. A technician comes out, measures the house, checks ductwork, and runs a Manual J load calculation. That tells us the exact BTU and tonnage your home needs, not what the previous owner guessed at.
- Written quote with three equipment options. We put together options at different efficiency tiers, each with a line-item price. You get the quote in writing and you keep it, whether or not you hire us.
- Equipment ordering and permit pull. Once you approve, we order the unit and pull the City of Dallas mechanical permit. Your installation date is set before any money changes hands.
- Full-day installation by a background-checked crew. Two technicians arrive in the stated window, remove the old equipment, install the new condenser, evaporator coil, and line set, and reconnect the electrical. Most jobs are done in a single day.
- Startup, commissioning, and walkthrough. We run the system through a full startup sequence, check refrigerant charge and airflow, and walk you through the new thermostat before we leave.
- Written guarantee and warranty registration. You get the 365-Day Done Right Promise in writing, and we register the manufacturer’s warranty that same day so there’s no gap in coverage.
AC Replacement Pricing in Dallas
Dallas AC replacement pricing runs higher than the national average because cooling loads are heavy and summer demand is brutal. Here’s what you should expect to see in this market:
| System Tier | Typical Dallas Price Range | What You Get |
|---|---|---|
| Entry-level, 14 SEER | $4,500 – $5,800 | Single-stage condenser, basic thermostat, standard efficiency. Gets the job done; best for budget-first replacements. |
| Mid-range, 16-17 SEER | $5,800 – $7,500 | Two-stage or variable-speed blower compatibility, better humidity control, noticeable summer bill reduction. |
| High-efficiency, 18-20 SEER | $7,500 – $9,800 | Variable-speed compressor, quiet operation, best humidity management. Pair with a matching furnace for full efficiency. |
Three things move the price: the size of your home (a 2-ton unit for a condo costs far less than a 5-ton unit for a 3,500-square-foot house in Preston Hollow), the condition of your ductwork, and whether the existing line set and electrical can be reused. We’ll show you all of it in the written breakdown.
We install and service Trane, Lennox, and Goodman equipment, along with Rheem and several other major brands. Our technicians are factory-trained across nine residential lines, so the install is done to the manufacturer’s spec, not improvised on site. Every replacement includes a free second visit if anything isn’t right, plus the full-year written guarantee.
If you’re comparing quotes from a couple of companies, bring us the other written estimates. We’ll explain line by line what’s included and what’s missing. Sometimes our number is higher, sometimes it’s lower. Either way, you’ll know exactly what you’re paying for.
Why Homeowners in Dallas Choose Dalton Heating & Air
The relationship between a homeowner and an HVAC company starts with a phone call and a quote. Too many Dallas companies get sloppy at exactly those two moments. We don’t.
- The Garrison Standard since 2003. Every job we take is bound to The Garrison Code: arrive inside the stated window, put the price in writing before starting, do the work by the book, leave the site clean, and stand behind the finished product for a full year. If any part of it isn’t done right, the 365-Day Done Right Promise means we return and make it right at no charge.
- Written price before any work starts. No verbal estimates, no “we’ll see what we’re working with” pricing. The number you sign off on is the number you pay.
- A live person answers the phone, 24/7. When it’s 105 degrees in July and your system goes down at 11 PM, you call and a human picks up. No voicemail queue, no “leave your number and we’ll get back to you.”
- Background-checked, uniformed technicians. The person we send to your door has been vetted, trained, and will introduce themselves by name. You’ll know who’s coming before they arrive.
- Full-year written guarantee on every install. Not a 30-day window, not a “parts only” exception. A year, in writing, on everything we install.

FAQs – AC Replacement
How much does AC replacement cost in Dallas?
AC replacement in Dallas typically costs $4,500 to $9,800 depending on system size, efficiency rating, and ductwork condition. Entry-level 14 SEER systems start around $4,500, mid-range 16-17 SEER units land between $5,800 and $7,500, and high-efficiency variable-speed systems run $7,500 to $9,800. Call (254) 280-5320 for a written quote based on your specific home.
Is it cheaper to repair or replace my AC?
As a rule of thumb, if the repair cost multiplied by the system’s age exceeds $5,000, replacement is the better financial call. On any unit over 12 years old with a compressor or refrigerant problem, we’ll almost always recommend replacement because you’d be putting thousands into a system that’s already past its service life. We’ll show you the math on both options before you decide.
Can you install a new AC the same week?
In most cases, yes. During spring and fall we can usually schedule replacement within 3 to 5 business days of your approval. Peak summer slots fill faster, but we keep emergency replacement capacity for total failures during heat waves. Call (254) 280-5320 and we’ll give you the next available window.
What size AC does my Dallas home need?
The right size depends on square footage, ceiling height, insulation, window area, and orientation. A 1,500-square-foot Dallas home typically needs a 3-ton unit, while a 2,500-square-foot two-story needs 4 to 5 tons. We run a Manual J load calculation on every replacement quote so the sizing is based on your actual house, not a rule of thumb.
Do you offer financing for AC replacement?
Yes, we offer financing options on full system replacements with approved credit. We’ll go over the terms during your quote appointment so you know the monthly number before any equipment is ordered. Call (254) 280-5320 to talk through your options.
