Get answers to common questions about hvac services in Seguin, Texas.
For a full system replacement in Seguin, homeowners can expect to pay between $5,000 and $12,000, with the final cost heavily dependent on home size, system efficiency (SEER rating), and installation complexity. Given our long, intense Texas summers, investing in a higher SEER unit (16+) can offer significant long-term savings on energy bills from CPS Energy. Always ensure your quote includes removal of the old unit, new refrigerant lines, and a new pad if needed.
The absolute best time is during the mild spring (March-April) or fall (October-November) seasons. Scheduling during these shoulder months ensures your system is serviced and ready for the peak summer demand before temperatures consistently hit the 90s and 100s, and it helps you avoid the highest service call wait times. This timing also allows for better scheduling flexibility and potential off-season promotions from local contractors.
Yes. In Texas, HVAC contractors must be licensed by the Texas Department of Licensing and Regulation (TDLR)—always verify this license online. Furthermore, the City of Seguin may require permits for new installations or major replacements, which your reputable contractor should handle. Proper permitting ensures the work meets local building codes, which is crucial for safety, efficiency, and protecting your home's value.
Look for a well-established local company with TDLR licensing, proper insurance, and strong community reviews. They should perform a detailed load calculation (Manual J) specific to your home's construction and Seguin's climate, not just recommend the same size unit you already have. Ask for references from homes in older Seguin neighborhoods like those near downtown, as they may have unique ductwork or insulation challenges.
During extended heatwaves with temperatures above 100°F, it is normal for your system to run for longer cycles to maintain your set temperature. However, if it runs non-stop without adequately cooling, it could indicate issues like low refrigerant, a dirty condenser coil (clogged with Texas oak pollen or grass), or an undersized unit. Consistent overwork drastically increases energy costs and wear, so a professional diagnostic is recommended.
