Get answers to common questions about hvac services in Round Rock, Texas.
For a standard 3-5 ton system suitable for our Texas heat, full replacement costs typically range from $5,500 to $12,000, including installation. The final price depends on the system's SEER rating (higher efficiency is crucial for our long cooling season), home size, and ductwork modifications. Always get itemized estimates from local, licensed contractors, as Round Rock's hard water can also influence the choice of compatible components.
The absolute best time is during the spring (February-April) or fall (October-November) shoulder seasons. Scheduling during these periods ensures your system is serviced before the intense summer heat (regularly 100°F+) or occasional winter freeze, and you'll find greater technician availability and often promotional pricing. Avoid emergency calls in peak summer by planning ahead.
Yes. While Texas has no statewide HVAC licensing, always verify your contractor is licensed by the City of Round Rock. More importantly, check for rebates from Pedernales Electric Cooperative (PEC) or Austin Energy, depending on your provider, for installing high-efficiency systems. These can offer significant savings, and using a higher SEER unit is a smart investment for our climate.
Prioritize companies with a strong local presence, verified Texas licenses (like TACLB), and excellent reviews specifically about service in Round Rock's climate. They should perform a detailed Manual J load calculation for your home, as our local sun exposure and attic heat significantly impact sizing. Be wary of quotes given over the phone without an in-home assessment.
During prolonged heatwaves with temperatures above 95°F, it is normal for your system to run nearly continuously to maintain set temperature, especially during peak afternoon hours. However, if it struggles to keep your home below 78°F or never reaches the set point, it may indicate an undersized unit, low refrigerant, or poor insulation—common issues in older Round Rock homes that a professional should evaluate.
