Local Factors
Several local factors influence the cost and process of HVAC & AC replacement in Castle Hills:
- Permits: Bexar County requires permits for HVAC work. Your contractor should handle this, but make sure it’s included in the quote. Failure to obtain proper permits can result in fines and delays.
- Installation Labor Rates: Labor costs in Castle Hills are competitive, but can vary based on contractor experience and demand. Get multiple quotes.
- Contractor Licensing: Texas law mandates that HVAC contractors be licensed by the TDLR (Texas Department of Licensing and Regulation). Always verify a contractor’s license before hiring them. This protects you from unqualified or unscrupulous contractors.
Weather Impact
Castle Hills experiences extremely hot and humid summers with temperatures frequently exceeding 100°F. This “heat dome” effect puts immense strain on AC systems. Here’s how the weather affects HVAC & AC replacement:
- High SEER2 Ratings are Essential: With energy costs in Texas being high, investing in a high SEER2-rated system is crucial for long-term savings on your electricity bills. The higher the SEER2 rating, the more efficient the unit is.
- Proper Sizing is Critical: An undersized unit will struggle to cool your home, while an oversized unit will cycle on and off frequently, leading to inefficiency and potential mold growth due to inadequate dehumidification. A Manual J load calculation is recommended.
- Humidity Control is Key: Texas humidity can lead to mold and mildew issues. Modern HVAC systems are designed to effectively remove humidity. Consider features like variable-speed blowers for better humidity control.
- Durability Matters: Choose a robust AC unit designed to withstand the Texas heat. Look for units with durable components and warranties.
