Most HVAC websites bury pricing because they want you to call before you can comparison shop. We do the opposite. Below are honest current ranges for the most common AC repairs and services. If anyone quotes you wildly outside these ranges (high or low), get a second opinion. We give second opinions for free.
Whether you're searching "how much does AC repair cost in Texas", "AC unit replacement cost Mabank", "furnace repair cost DFW", "average HVAC installation price", "capacitor replacement cost", or "new air conditioner price 3-ton" — this page covers the realistic ranges you should expect from any honest HVAC contractor across Mabank, the Cedar Creek Lake Area, and the entire Dallas–Fort Worth metroplex.
Parts & Repairs
Capacitor Replacement
Pricing varies by system size (tonnage), brand/part quality, and whether the part is covered under manufacturer warranty.
Higher-end systems and warranty handling can move pricing up or down.
Contactor Replacement
Costs change based on electrical configuration, brand, and accessibility (especially tight service areas or rooftop/attic access).
Some systems require additional electrical troubleshooting or upgraded components.
Blower Motor
Wide range because ECM motors and control modules cost more than standard motors, and labor can vary by equipment design.
ECM motor + module replacements are the common reason for the high end.
Heat Exchanger (Furnace)
Pricing depends on furnace make/model, whether the heat exchanger is available, and whether replacement is covered under manufacturer warranty.
Some cases make more sense to replace the furnace depending on age and overall condition.
Refrigerant (Freon)
Per-pound pricing depends on refrigerant type (R-22 vs R-410A), supply/availability, and EPA regulations.
R-22 is often significantly higher due to phase-out and limited supply.
Refrigerant Leak Repair
Leak location drives cost — simple service port leaks are cheaper than evaporator coil leaks. Recharge amount also affects total.
Coil-related leaks and larger recharges typically push toward the higher end.
Compressor Replacement
Depends on tonnage, refrigerant type, and warranty status. Labor and start components may also be required.
If warranty applies, you may only pay labor + related parts.
Thermostat Replacement
Pricing depends on thermostat type (basic vs Wi-Fi/smart) and wiring compatibility (including common wire needs).
Smart thermostats and rewiring/adapter needs increase cost.
Service Call & Diagnostic
Varies by travel distance, time of day, and whether it’s scheduled service or urgent after-hours work.
Standard daytime diagnostic is $79; after-hours or holiday service may run up to $129. Diagnostic fee is waived when you book the repair with us.
System Replacement (Installed)
Full system replacement pricing depends on tonnage, efficiency tier, ductwork condition, and any custom requirements. Honest current ranges:
Straight Cool System (AC + Furnace or Air Handler)
A traditional cooling system paired with either a gas furnace or electric air handler. This is one of the most common configurations in Mabank homes with existing ductwork. Ideal for homeowners wanting reliable cooling without upgrading to advanced variable-speed technology.
Pricing varies based on tonnage, brand selection, electrical upgrades, and whether indoor equipment must be modified.
Heat Pump System
An all-electric heating and cooling solution that transfers heat rather than creating it. Heat pumps can deliver up to 3–4x greater heating efficiency than electric resistance heat (heat strips) under normal operating conditions. Popular in Texas due to lower operating costs and year-round efficiency.
Final cost depends on efficiency rating, inverter technology, and backup heat configuration.
High-Efficiency System (16–18 SEER2)
Mid-to-high efficiency systems designed for improved comfort, quieter operation, and lower utility bills. Often includes two-stage or variable-speed technology for better humidity control in East Texas climates.
Higher ratings, communicating thermostats, and upgraded indoor air quality components increase investment.
Ultra High-Efficiency System (20–26 SEER)
Premium inverter-driven systems offering maximum efficiency, extremely quiet operation, advanced humidity control, and smart communicating controls. Best suited for homeowners prioritizing long-term energy savings and top-tier comfort performance.
Includes advanced compressor technology and premium indoor equipment configurations.
Full Ductwork Replacement
Complete removal and replacement of attic duct systems. Options include higher R-value insulation levels and antimicrobial duct materials for improved air quality and condensation resistance.
Pricing depends on square footage, attic layout, R-value selection, and specialty duct upgrades.
0% APR financing is available for qualified buyers on system replacements and major repairs.

- UV-C coil sterilization (single lamp): $400–$700 installed
- UV-C dual-lamp air sterilization: $700–$1,100 installed
- Whole-home media filter cabinet (4–5 inch): $480–$780 installed
- HEPA bypass filtration: $1,800–$2,800 installed
- Whole-home dehumidifier (70-pint): $1,800–$2,400 installed
- Whole-home dehumidifier (90-pint): $2,400–$3,200 installed
- Whole-home humidifier (winter): $600–$1,100 installed
- Air duct cleaning (avg 2,000 sq ft home): $399–$699
Common HVAC Cost Questions
How much does AC repair cost in Mabank, TX?
The most common AC repairs in our service area — capacitor, contactor, thermostat — run $200–$850 depending on parts and warranty status.

Every diagnostic is $79 standard or up to $129 for after-hours and holiday service.
How much does it cost to replace a 3-ton AC unit?
A standard straight-cool 3-ton AC system replacement (AC + furnace or air handler) in Mabank or DFW typically runs $7,000–$12,000 fully installed. A heat pump system in the same tonnage runs $8,500–$13,500. High-efficiency 16–18 SEER2 systems run $12,000–$20,000, and ultra-high-efficiency 20–26 SEER inverter systems run $20,000–$30,000.

How much does furnace repair cost?
Most furnace repairs across our DFW service area run $200–$800 for common failures — igniter, flame sensor, control board, or thermostat-related issues. Blower motor replacements range $800–$4,200 depending on whether it's a standard PSC motor or an ECM module. Heat exchanger replacement runs $1,500–$4,500 and often makes more economic sense as a furnace replacement on units over 12 years old; we'll tell you straight if replacement is the better call.
What does a new HVAC system cost installed?
A complete new HVAC system installation in Mabank, Cedar Creek Lake Area, or DFW ranges from $7,000 (basic straight-cool) to $30,000 (ultra-high-efficiency inverter system).
