Frequently Asked Questions About HVAC in S F A U

Get answers to common questions about hvac services in S F A U, Texas.

1What is the typical cost range for replacing a central AC unit in San Felipe, Texas?

For a standard single-family home in San Felipe, a full AC replacement typically ranges from $5,000 to $12,000. The final cost depends heavily on the unit's size (tonnage), efficiency rating (SEER), and the complexity of the installation, such as ductwork modifications. Given our intense Texas summers, investing in a higher-SEER unit (16+) can offer significant long-term savings on energy bills, despite a higher upfront cost.

2When is the best time to schedule HVAC maintenance or replacement in the San Felipe area?

The absolute best time is during the spring (March-May) or fall (September-November). Scheduling service during these mild shoulder seasons ensures your system is fully prepared for the peak summer heat and winter cold, and you'll have much better availability from local technicians. Waiting until the first major heatwave in June or July often leads to emergency service calls, longer wait times, and potentially higher costs.

3Are there any local regulations or rebates in Texas I should know about when upgrading my HVAC system?

While San Felipe follows Texas's statewide HVAC licensing requirements (always verify your contractor is TACLB licensed), a key local consideration is ensuring any new system complies with your specific municipality's permitting and inspection rules. Furthermore, many Texas utilities, like CenterPoint Energy, offer rebates for installing high-efficiency heat pumps or air conditioners, and there are also potential federal tax credits available for qualifying ENERGY STAR® systems.

4How do I choose a reliable HVAC contractor in the San Felipe/Austin County area?

Start by verifying they hold a valid Texas Air Conditioning and Refrigeration Contractor License (TACLB) and carry adequate insurance. Look for established local companies with strong community reputations, as they understand the specific climate challenges of our region. Always request detailed, written estimates, check online reviews, and ask for references from recent installations in the area to gauge their quality and customer service.

5My AC runs constantly on hot days but doesn't cool my house adequately. What's the most common cause in our climate?

In the San Felipe heat, the most frequent culprits are a dirty or clogged air filter, low refrigerant levels due to a leak, or a failing capacitor. However, it could also be that your system is simply undersized for your home, a common issue in older Texas properties. A professional diagnostic is crucial, as running an overworked system not only fails to cool your home but also drastically increases energy costs and the risk of a complete breakdown.
