HVAC & Air Conditioning FAQ - Killeen, TX
How much does AC repair cost in Texas?
Most AC repairs in Texas cost between $150 and $600. A basic service call with diagnosis runs $75-$150. Major repairs like compressor replacement can be $1,000-$2,500. Getting multiple quotes helps ensure fair pricing.
How often should I service my AC in Texas?
In Texas, with heavy summer usage, HVAC systems should be serviced twice a year: once in spring before cooling season and once in fall before heating season. Regular maintenance extends system life by 5-10 years.
When should I replace my AC instead of repairing it?
Consider replacement if your system is over 10-15 years old, uses R-22 refrigerant (being phased out), needs repairs costing more than 50% of a new system, or your energy bills keep climbing despite repairs.
What size AC do I need for my Texas home?
In Texas, the general rule is 1 ton of cooling per 500-600 square feet. A 2,000 sq ft home typically needs a 3.5-4 ton unit. However, insulation quality, windows, and sun exposure all factor in. A proper load calculation is recommended.
Why is my AC running but not cooling?
Common causes include low refrigerant (leak), dirty air filter restricting airflow, frozen evaporator coil, faulty compressor, or thermostat issues. Start by checking and replacing your air filter, then call a tech if the problem persists.
Do HVAC technicians need a license in Texas?
Yes. Texas requires HVAC technicians to hold a license from the Texas Department of Licensing and Regulation (TDLR). All technicians on TX24H are verified and properly licensed.
