Get answers to common questions about hvac services in LSI, Texas.
In the LSI area, a full central AC replacement typically ranges from $5,500 to $12,000+, depending heavily on system size (measured in tons), efficiency rating (SEER), and brand. Key local factors include the need for a system robust enough for our intense summer heat, which may require a larger unit, and whether your existing ductwork needs modifications to handle the new system's airflow. Always get itemized estimates from multiple licensed local contractors.
The absolute best times are during the mild shoulder seasons of early spring (March-April) and early fall (September-October). Scheduling during these periods ensures your system is serviced before the peak demand of the brutal Texas summer, and you'll find greater contractor availability and potentially better pricing than during the summer crisis period when everyone's AC is failing.
While LSI follows Texas state codes, which do not have statewide HVAC licensing, always verify your contractor is licensed, bonded, and insured. For rebates, check with your local utility provider (like Oncor) and the federal government for tax credits on high-efficiency systems (SEER 16+). Some manufacturers also offer regional promotions, especially for systems designed to perform in high-heat climates like ours.
Prioritize contractors who are locally established, have strong community reviews, and hold a Texas Air Conditioning and Refrigeration Contractor License (TACLA). They should perform a detailed Manual J load calculation specific to your home's construction and our local climate to correctly size your system. Avoid those who give quotes over the phone without an in-home inspection.
Given our extended periods of 100+ degree days with high humidity, it is normal for your system to run frequently, especially during the afternoon peak heat. However, if it runs non-stop without adequately cooling your home (maintaining a ~20-degree difference from outside), it indicates a problem like an undersized unit, low refrigerant, dirty coils, or failing components that require immediate professional diagnosis to prevent a costly breakdown.
