Recommended unit for San Juan
Given Texas’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most San Juan homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

What San Juan code requires
Installing or replacing an HVAC system in San Juan follows Texas rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southeast, <45k BTU)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
HVAC work must be done by a TDLR-licensed Air Conditioning & Refrigeration contractor, and the licensed contractor (not the homeowner) pulls the required mechanical permit.

AC Installation in San Juan, explained.
What affects AC installation cost in San Juan?
Several factors drive the price up or down. The system type—central AC, heat pump, or ductless—has a big impact, with heat pumps typically costing more upfront but offering year-round efficiency. Adding or replacing ductwork can add $1,800–$4,600+ to the job. The home's age (median built 2001) may require electrical or structural updates. Finally, the required mechanical permit and TDLR-licensed labor are fixed costs that ensure code compliance and safe installation.
Common AC installation issues in San Juan
Older ductwork
Homes built around 2001 may have undersized or leaky ducts that need replacement or sealing, adding cost and time to the installation.
Permit and code compliance
Texas requires a mechanical permit pulled by a TDLR-licensed contractor. Failure to obtain one can lead to fines and issues when selling the home.
High cooling load
San Juan's hot-humid climate means the system must be sized correctly. An oversized unit short-cycles and wastes energy; an undersized one struggles to cool.
