While the table below shows the *type* of HVAC systems, remember that the actual price will be significantly affected by the tonnage (BTUs), SEER2 rating and Brand.

System Type Average Price (Installed) Notes
Central Air Conditioner $4,000 – $8,000 Most common type, requires existing ductwork. Price varies with SEER2 rating and tonnage.
Heat Pump $4,500 – $9,000 Provides both heating and cooling, more energy-efficient in milder winters.
Ductless Mini-Split $3,000 – $7,000 (per zone) Ideal for rooms without ductwork or for targeted cooling/heating. Price is *per zone* (indoor unit).

Local Factors

When budgeting for your HVAC or AC replacement in Willis, consider these local factors:

  • Permits: Montgomery County requires permits for HVAC replacements. The cost varies depending on the scope of the work, but expect to pay around $100-$300. Your contractor should handle the permit process.
  • Installation Labor Rates: Expect to pay between $75 and $150 per hour for qualified HVAC technicians in the Willis area. Complex installations or ductwork modifications will increase labor costs.

Weather Impact

Willis, Texas, experiences extremely hot and humid summers with temperatures frequently soaring over 100°F. These “heat domes” put immense strain on AC systems. Investing in a high-quality, heavy-duty AC unit with a good SEER2 rating is crucial. The higher the SEER2 rating, the more energy-efficient the unit, and the lower your electricity bills will be. Given the humidity, consider systems designed to actively manage moisture to prevent mold growth.

Keep in mind that Texas law requires all HVAC contractors to be licensed by the TDLR (Texas Department of Licensing and Regulation). Always verify your contractor’s license before hiring them.

FAQ

  1. How long does an HVAC replacement typically take?
    A standard HVAC replacement usually takes 1-3 days, depending on the complexity of the job, ductwork modifications, and weather conditions.
  2. How do I know what size HVAC unit I need?
    A qualified HVAC technician will perform a “Manual J” load calculation to determine the correct BTU size for your home, considering factors like square footage, insulation, window efficiency, and climate.
  3. What is SEER2, and why is it important?
    SEER2 (Seasonal Energy Efficiency Ratio 2) is a measure of an AC unit’s cooling efficiency. Higher SEER2 ratings mean lower energy bills. The federal minimum SEER2 standard is now in effect, so all new AC units must meet these higher efficiency standards.
