Local Factors
In Nassau Bay, being part of Harris County, you’ll likely need a permit for HVAC replacement, especially if it involves significant changes to your ductwork or electrical system. Check with the city of Nassau Bay and Harris County permit offices for specific requirements and fees. Expect labor rates to be around $75-$150 per hour, depending on the contractor’s experience and the complexity of the job. Remember to verify your contractor’s license at TDLR (Texas Department of Licensing and Regulation) to ensure they are qualified to perform the work.
Weather Impact
Nassau Bay’s extremely hot and humid summers, with temperatures frequently exceeding 100°F, put a significant strain on HVAC systems. When choosing a new AC unit, prioritize models designed to withstand these “heat domes.” Consider a unit with a higher SEER2 rating (as required by the 2026 standards) to reduce your energy consumption and lower your sky-high Texas electric bills. Efficient humidity control is also crucial to prevent mold growth and maintain indoor comfort. Look for systems with dehumidification features.
