What AC Installation Leander TX Service Includes

AC installation is more than dropping in a new unit. Proper sizing, ductwork evaluation, refrigerant line work, electrical, drain, and start-up testing all matter for the system to deliver real cooling performance over the long term.

Load Calculation

Right-sizing the AC for your home matters. Too big short cycles, too small struggles. We evaluate the load before recommending a unit.

Equipment Options Reviewed

We review system choices with you — efficiency tier, capacity, brand, and features — so you understand what you're choosing and why.

Old Unit Removal

Safe removal and disposal of the existing AC system, including refrigerant recovery per EPA guidelines.

Ductwork Inspection

A check of supply, return, and any leak points. Even a great new AC underperforms if the ductwork has problems.

New System Set & Sealed

Indoor and outdoor units installed with proper clearances, refrigerant lines connected, condensate drain run, and electrical hookups completed.

Electrical & Disconnect

Power requirements, breaker sizing, disconnect, and whip — all checked and corrected as needed for the new system.

Start-Up & Performance

System started, refrigerant levels verified, airflow measured, temperature differentials checked, thermostat configured.

Walkthrough & Cleanup

Thermostat operation walkthrough, basic care tips, and full cleanup before the install is considered complete.

Install or Repair First?

When AC Installation Leander TX Makes Sense

Sometimes a new AC is the smart move. Sometimes repair is the better path. The right answer depends on system age, condition, repair history, and how the unit performs after a real diagnostic.

Install IndicatorsAC Installation Makes Sense When

Replacement may be the smarter long-term call when the existing system has reached the end of its useful life — or when repair costs no longer justify keeping the AC.

Install & Replace Indicators
  • Existing system is 12+ years old with declining performance
  • AC repairs are getting more frequent and expensive
  • Energy bills climbing despite proper maintenance
  • System struggles to keep up during peak Texas heat
  • Major component failure (compressor, coil, etc.)
  • Outdated refrigerant the AC depends on
  • New construction or major home addition

Repair-First IndicatorsTry AC Repair First When

For most AC issues, a targeted repair is the right answer. We don't push installation when repair is the smarter call — diagnostics drive the recommendation.

Repair Indicators
  • System is under 10 years old and well-maintained
  • The diagnosed issue is isolated (capacitor, contactor, drain)
  • Repair cost is significantly less than replacement
  • System has been keeping up with cooling demand overall
  • No history of repeated major component failures
  • Energy bills have been stable, not climbing

FAQ

AC Installation Leander TX Questions Homeowners Ask

Question not answered here?

Reach out and we'll help you figure out the right path for your AC.

How long does AC installation take in Leander, TX?

Most residential AC installations in Leander take a single day, depending on the system, ductwork condition, and electrical work needed. We confirm timing during the in-home evaluation so you know what to plan for.

How do you size an AC system properly?

Proper sizing comes from a load calculation — not just square footage. We evaluate the home's insulation, windows, orientation, ductwork, and other factors. Oversized systems short cycle and don't dehumidify well; undersized systems struggle in Texas heat.

Should I repair my AC or install a new one?

It depends on system age, repair history, and condition. For systems under 10 years old with isolated issues, AC repair usually makes sense. For 12+ year old systems with frequent or expensive repairs, installation may be the smarter long-term choice.

Is DMO Mechanical a licensed AC installer?

Yes. DMO Mechanical LLC is a licensed Texas HVAC contractor. License number: TACLB127781E. The license covers AC installation work for both residential and commercial properties across Texas.

What efficiency rating should I look for in a new AC?

Higher SEER2 ratings generally use less energy but cost more upfront. The right efficiency tier depends on your home's cooling demand, how long you plan to stay, and your budget. We help compare the options based on real numbers, not pressure.

Will my old ductwork work with a new AC system?

Sometimes. A ductwork inspection during the install evaluation tells us whether the existing system is sized correctly, sealed properly, and free of leaks. Repairs or replacement of duct sections may be recommended to get the most out of a new AC.

Which Central Texas cities do you serve for AC installation?
