What Matters More Than Brand
Installation Quality
Even the best AC brand will underperform if installed incorrectly. Studies show that improper installation can reduce efficiency by 25-30% and cut system life in half. Look for:
- NATE-certified technicians
- Proper load calculations
- Quality ductwork assessment
- Correct refrigerant charge
- Thorough testing after installation
Proper Sizing
An oversized unit short-cycles, wasting energy and wearing out faster. An undersized unit runs constantly without adequate cooling. Professional load calculations (Manual J) ensure proper sizing.
SEER Rating
For Tucson's climate, we recommend at least 16 SEER, though 18+ provides better long-term value. Higher SEER means:
- Lower operating costs
- Better humidity control
- Quieter operation
- Smaller environmental footprint
Features That Matter in Arizona
- Two-stage or variable-speed compressor: Better humidity control and longer, gentler cycles
- Corrosion-resistant coils: Important for monsoon humidity
- High-quality air filtration: Addresses desert dust
- Smart thermostat compatibility: Optimizes efficiency
