Get answers to common questions about hvac services in Diana, Texas.
For a standard 3-4 ton system suitable for Diana's hot and humid East Texas climate, a full replacement typically ranges from $5,500 to $9,500. The final cost depends on your home's square footage, the system's SEER (efficiency) rating, and the complexity of the installation. We recommend getting multiple itemized quotes from local, licensed contractors, as regional material costs and the high demand during our long cooling season can influence pricing.
The absolute best times are during the mild shoulder seasons of early spring (March-April) and early fall (September-October). Scheduling service during these periods ensures your system is fully tuned up before the intense summer heat arrives and avoids the peak demand rush when HVAC companies are busiest with emergency breakdowns. This timing often leads to better availability and potential promotional pricing.
Texas has no statewide HVAC licensing board; technicians must be licensed by the Texas Department of Licensing and Regulation (TDLR). Always verify this license. For rebates, while state programs change, local Diana residents should check with their specific electricity provider (like SWEPCO or Upshur Rural Electric) for potential seasonal rebates on high-efficiency systems, and always inquire about federal tax credits for qualifying ENERGY STAR® equipment.
Prioritize contractors who are TDLR-licensed, insured, and have a strong local reputation in Upshur County. Look for companies experienced with the specific challenges of our region, such as managing humidity and servicing systems that run heavily from May through September. Always ask for local references, read verified reviews, and ensure they perform a detailed load calculation (Manual J) for any new installation, not just a simple tonnage guess.
Given Diana's summer temperatures that regularly reach the mid-90s with high humidity, it is normal for your system to run frequently, especially during the peak afternoon heat. However, if it runs non-stop without adequately cooling your home, it could indicate an undersized unit, low refrigerant, a failing component, or insufficient insulation. A professional evaluation is recommended to ensure your system is operating correctly and efficiently under our demanding local conditions.
