| Job Type | Low Estimate | High Estimate | Notes |
|---|---|---|---|
| AC tune-up / maintenance | $75 | $200 | Annual recommended |
| AC repair (minor) | $150 | $600 | Capacitors, contactors, refrigerant |
| AC repair (major) | $600 | $2,000 | Compressor, coil issues |
| AC unit replacement | $4,000 | $9,000 | Outdoor unit only |
| Full system replacement (AC + furnace) | $7,000 | $14,000 | Complete HVAC overhaul |
| Ductwork repair / replacement | $1,000 | $5,000 | Varies widely by access |
The single biggest driver of cost is how much work actually needs to be done. A small repair is a fraction of a full replacement. Always get a professional inspection before assuming you need the most expensive option — many homeowners pay for full replacements when targeted repairs would solve the problem at 10–20% of the cost.
Material choice can swing total cost by 50–100%. For hvac, budget materials get the job done but premium options last significantly longer and often come with better warranties. The right choice depends on how long you plan to stay in the home and your climate conditions.
Contractor labor rates vary by city. Markets like New York, San Francisco, and Seattle run 20–40% above national averages. Midwest and Southern cities typically run 5–15% below. Dallas's rates are near or below the national average.
After major storms, demand for hvac contractors spikes and prices follow. If your project isn't urgent, scheduling during off-peak seasons (fall for HVAC, late winter for roofing) can save 5–15% and get you faster service from less-rushed contractors.

Texas requires HVAC contractors to hold a state license from the Texas Department of Licensing and Regulation. Always verify licensing before hiring — unlicensed HVAC work can void warranties and insurance coverage.
Spring (March–May) and fall (September–November) are ideal — contractors are less busy, prices may be slightly lower, and you have time to shop around without emergency pressure.
