What to expect
- Evaluation of whether existing ductwork and the line set can be reused or should be updated.
- Right-sizing the new system rather than copying the old tonnage if the old unit was mis-sized.
- Comparison of single-stage, two-stage, and variable-speed options for Texas humidity and heat.
- Removal and disposal of the old system and refrigerant per EPA rules.
When to call
- Your AC uses phased-out R-22 refrigerant and a major component failed
- Repeated repairs in consecutive summers
- Rising energy bills despite maintenance
- Comfort problems that point to a mis-sized or worn-out system
Questions to ask
- Is my existing ductwork adequate, or will it limit the new system?
- What efficiency tier gives the best payback for my usage?
- What's included in the price — permits, disposal, thermostat, labor warranty?
- Is the replacement covered by both manufacturer and labor warranties?
What it costs: Replacement pricing depends on tonnage, efficiency tier, and ductwork. Get itemized written quotes at matching efficiency levels. Several guide companies advertise financing — confirm terms in writing. Any figures on company sites are estimates, not quotes.

Replacement in Dallas: FAQs
How long does an AC replacement take in Dallas?
A straightforward like-for-like changeout is often completed in a day; jobs involving ductwork, electrical upgrades, or a different system type can take longer. Ask the contractor for a specific timeline.
What size AC do I need for my Dallas home?
Sizing should come from a Manual J load calculation that accounts for square footage, insulation, windows, and orientation — not a rule-of-thumb per square foot. An oversized unit short-cycles and dehumidifies poorly in Texas humidity.
