Get answers to common questions about hvac services in Justin, Texas.
For a full system replacement (air conditioner and furnace or heat pump) in a standard single-family home, homeowners in Justin can expect a typical range of $6,500 to $12,000. The final cost depends heavily on the home's square footage, the system's efficiency rating (SEER2), and the complexity of the installation. Given our North Texas climate with long, intense summers, investing in a higher-efficiency unit (16+ SEER2) can offer significant long-term savings on energy bills despite a higher upfront cost.
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 fully serviced before the peak summer demand and winter cold snaps, and you'll find greater technician availability and often more flexible scheduling. Waiting until the first 100-degree day or a freezing cold front often leads to emergency service calls, longer wait times, and higher prices.
Yes, Texas requires that all HVAC contractors hold a state license through the Texas Department of Licensing and Regulation (TDLR). Always verify a contractor's TDLR license number. Furthermore, for homes in newer developments, you may have specific homeowner association (HOA) covenants in Justin that dictate where outdoor condenser units can be placed or require aesthetic screening, so it's important to check your HOA rules before installation.
Start by confirming their TDLR license and insurance. Then, look for established local companies with strong, verifiable reviews on platforms like Google or Nextdoor specific to Justin and surrounding Denton County communities. A reputable contractor will perform a detailed load calculation (Manual J) for your specific home—not just recommend the same size unit—and provide a written, itemized quote that includes warranty details on both parts and labor.
During extended periods of extreme heat (common with consecutive days over 100°F), it is normal for your system to run nearly continuously in the afternoon to maintain your set temperature. However, if it runs non-stop without adequately cooling the home or struggles to bring the temperature down more than 15-20 degrees from the outside temperature, it may indicate an issue like low refrigerant, a dirty coil, or an undersized system that requires professional diagnosis.
