Get answers to common questions about hvac services in Cost, Texas.
For a standard 3-ton unit common in Cost area homes, full replacement costs typically range from $5,500 to $9,500, including installation. This price is influenced by the system's SEER (Seasonal Energy Efficiency Ratio) rating; higher SEER units cost more upfront but save significantly on energy bills during our long, hot Texas summers. Always get itemized quotes from local, licensed contractors that include removal of the old unit, new refrigerant lines if needed, and all labor.
The absolute best time is during the spring (March-May) or fall (October-November). Scheduling during these mild shoulder seasons ensures your system is fully serviced before the peak summer heat or occasional winter chill, and you'll find greater technician availability and potentially better pricing. Waiting until a mid-summer breakdown in July or August often leads to emergency service fees and longer wait times due to high demand.
Yes. Texas has statewide licensing requirements for HVAC contractors through the Texas Department of Licensing and Regulation (TDLR)—always verify your provider's license. Furthermore, while Cost itself may not have specific ordinances, your utility provider (such as AEP Texas or Oncor) often offers rebates for upgrading to high-efficiency systems. Additionally, Texas has specific codes for proper refrigerant handling and system sizing that reputable contractors will follow.
Prioritize companies that are locally established, TDLR-licensed, insured, and have positive, verifiable reviews from neighbors in Gonzales County or nearby towns. Ask for references from recent installations. A trustworthy provider will perform a detailed Manual J load calculation specific to your home's construction and the local climate, not just recommend the same size as your old unit, and will provide a clear, written contract.
Given the high humidity and dust common in the Cost region, the most frequent causes are a dirty or restricted air filter, clogged condenser coils (the outdoor unit), or low refrigerant charge due to leaks. Restricted airflow forces the system to work harder. Start by checking and replacing your air filter monthly during peak season. If that doesn't resolve it, call a professional for a cleaning and diagnostic, as low refrigerant is a serious issue that requires a certified technician to repair.
