Signs Your Air Conditioner Needs Repair

Do not wait for a complete breakdown. Watch for these warning signs:

1. AC not cooling properly — Your system runs but the house is not getting cold. Could be low refrigerant, a dirty filter, or a failing compressor. Troubleshooting guide: AC not blowing cold air. See also our full AC not cooling troubleshooting page.
2. High energy bills — A sudden spike in your electric bill often means your AC is working harder than it should due to a failing component or reduced efficiency.
3. Strange noises — Grinding, squealing, banging, or buzzing sounds indicate mechanical problems that will get worse if ignored.
4. Unusual odors — Musty smells suggest mold in your ductwork. Burning smells require immediate attention — turn off the system and call us.
5. Frequent cycling — The system turns on and off every few minutes instead of running in longer cycles. This wastes energy and wears out components.
6. Poor airflow — Weak airflow from your vents may indicate a failing blower motor, clogged filter, or ductwork problems.
7. Water leaks — Water pooling around your indoor unit usually means a clogged condensate drain or a frozen coil that is thawing.
8. Ice on your AC unit — Ice on the refrigerant lines, evaporator coil, or outdoor unit signals a serious problem. Why your AC is freezing up.
9. Thermostat problems — If your thermostat reading does not match the actual temperature, or if the system does not respond to thermostat changes. How to troubleshoot your thermostat.
10. System is 10+ years old with increasing repairs — At some point, continued repairs cost more than replacement. How long does an AC last?

AC Maintenance: Keep Your System Running Efficiently

Regular maintenance is the best way to prevent breakdowns, lower your energy bills, and extend the life of your AC system. In Central Texas, where AC systems run 7-8 months per year, annual maintenance is essential.

What an AC Tune-Up Includes:

• Clean evaporator and condenser coils
• Check and adjust refrigerant levels
• Inspect and tighten electrical connections
• Calibrate thermostat operation
• Clean condensate drain line
• Inspect ductwork for leaks
• Replace air filter
• Test system performance and safety controls
• Measure airflow and temperature differential

Benefits of Regular AC Maintenance:

• Up to 15% lower energy bills
• Fewer breakdowns and emergency repairs
• Extended equipment lifespan (15-20 years vs 10-12 years without maintenance)
• Better indoor air quality
• Manufacturer warranty protection (most warranties require annual maintenance)

Learn about our maintenance plans or read our HVAC maintenance cost guide.

Common AC Problems in Central Texas

Central Texas climate creates specific challenges for air conditioning systems:

• Extreme heat stress — Systems running 12-16 hours per day during summer face accelerated wear on compressors, capacitors, and fan motors.
• High humidity — Excess moisture overworks your AC and can cause mold growth in ductwork. How to improve indoor air quality.
• Allergens and dust — Texas cedar, oak pollen, and dust require more frequent filter changes. Indoor air quality services.
• Storm damage — Lightning strikes and power surges damage electrical components. Surge protectors help but do not eliminate the risk.

Frequently Asked Questions About AC Repair & Installation

How much does AC repair cost in Killeen, TX?

Most AC repairs in Killeen and Central Texas cost between $150 and $700. A diagnostic service call is $75-$150. Common repairs like capacitor or contactor replacement cost $150-$350. Major repairs like compressor replacement can cost $1,200-$2,500. Texas Temp Masters provides upfront estimates before starting work. Read our complete AC repair cost guide.

How long does AC repair take?

Most AC repairs are completed in 1-2 hours during a single visit. Our trucks are stocked with the most common parts — capacitors, contactors, fan motors, thermostats, and relays. If a specialty part needs to be ordered, we will let you know the timeline upfront. Compressor and coil replacements may take 3-4 hours.

How often should I have my AC serviced?

At minimum, once per year — ideally in spring before the cooling season begins. In Central Texas, where AC systems work harder and longer than most of the country, annual professional maintenance is essential for reliability and efficiency. Learn about our maintenance plans.

How long does a new AC installation take?

A standard AC replacement (same system type, same location) typically takes 4-8 hours and is completed in one day. If ductwork modifications are needed or you are switching system types (for example, adding a ductless mini-split), it may take 1-2 days. We always provide a timeline estimate during your free consultation.

What size AC do I need for my house in Texas?

AC sizing depends on your home’s square footage, insulation, window quality, ceiling height, and sun exposure. As a rough guide, Texas homes typically need 1 ton of cooling per 500-600 square feet. A 2,000 sq ft home in Killeen usually needs a 3.5-4 ton system. However, proper Manual J load calculations are essential — an oversized system wastes energy and dehumidifies poorly. Use our BTU Calculator or read our sizing guide.

Should I repair or replace my AC unit?

Consider replacement if your AC is over 10-12 years old, uses R-22 refrigerant (phased out and very expensive), requires frequent repairs, or if the repair costs more than half the price of a new system. Newer AC systems are 30-50% more energy efficient, which saves hundreds per year on electricity. Use our Repair or Replace Calculator to run the numbers for your situation.

What SEER rating should I choose for a new AC in Texas?

For Central Texas, we recommend at least 16 SEER for the best balance of upfront cost and long-term energy savings. Since your AC runs 7-8 months per year, the energy savings from a higher SEER unit pay for themselves faster here than in cooler climates. Systems rated 16+ SEER may also qualify for federal tax credits up to $2,000. Learn about SEER vs SEER2 ratings.

Do you offer financing for new AC installations?

Yes. Texas Temp Masters offers flexible financing options for new AC installations, including low monthly payments, competitive interest rates, and same-as-cash offers for qualified buyers. Learn about our financing options.
