When to Install a New AC System vs. Repair the Old One
Not every failing AC needs replacement. Here is the honest framework KAC Express uses in The Woodlands.
The 5,000 Dollar Rule
Multiply your repair estimate by your system age in years. If the result exceeds 5,000 dollars, installation of a new system usually wins long-term. A 650 dollar repair on a 10-year-old system equals 6,500 dollars, install new. A 650 dollar repair on a 4-year-old system equals 2,600 dollars, repair.
Age Thresholds
Clear Signs It Is Time to Install New
- Â Two or more significant repairs (over 500 dollars each) in the last 24 months
- Summer electric bill up 20 percent or more with no rate change from CenterPoint or Entergy
- System uses R-22 refrigerant (phased out by the EPA in 2020)
- Rooms in your Woodlands home consistently 4 to 6 degrees warmer than others
- Compressor failed and you were quoted 1,800 to 3,500 dollars for repair on a 12+ year-old system

Our AC Installation Process in The Woodlands, TX
A proper installation in The Woodlands takes one full day for a straight replacement. Here is what happens.
Free In-Home Estimate
(60 to 90 min)
A KAC Express Comfort Advisor visits your Woodlands home, performs a written Manual J load calculation, inspects existing ductwork for leakage and sizing, verifies electrical circuit adequacy, and discusses efficiency and budget. You receive 2 to 3 written system options within 24 hours.
System Selection and Financing
Once you select a system, we submit manufacturer warranty registration, apply for available instant rebates, and process financing paperwork if requested. Financing decisions typically arrive in 2 to 5 minutes. Installation is scheduled within 3 to 7 days.
Old System Removal
(EPA Compliant)
Refrigerant is recovered per EPA Section 608 requirements (never vented to atmosphere). The old outdoor condensing unit, indoor coil or air handler, and any damaged ductwork are removed and hauled away for recycling at no extra cost.
New System Installation and Commissioning
The new outdoor condensing unit is set on a level pad. The new indoor coil or air handler is installed. Refrigerant lines are brazed with nitrogen purge, pressure-tested at 300+ PSI, and vacuumed to below 500 microns. System is charged with R-410A to manufacturer specification, verified with superheat and subcooling measurements. Full cooling cycle tested.
Final Walkthrough and Warranty Registration
Our installer walks you through system operation, thermostat programming, filter change intervals, and warranty terms. Manufacturer warranty registration is completed on-site (a step many contractors skip). You receive a written completion package with your AHRI certificate.
AC System Sizing for The Woodlands, TX Homes

What Is a Manual J Load Calculation?
