When to Call for Emergency HVAC Service

Not every HVAC problem is an emergency, but some situations require immediate professional attention. Here is how to tell the difference:

Immediate Emergency Situations — Call Right Away:

• Complete system failure — no heating in freezing weather or no cooling during extreme heat
• Gas leaks or sulfur/rotten egg odors — leave your home immediately and call 911, then call us
• Electrical burning smells or sparking from your HVAC unit
• Carbon monoxide detector alarm going off (evacuate first, then call)
• Water flooding from a broken HVAC unit threatening property damage
• Mechanical failure with loud banging, screeching, or grinding noises
• HVAC system creating a fire hazard (smoke, burning smell, visible damage)

Urgent Service Needs — Same-Day Repair Recommended:

• AC blowing warm air instead of cold — see our AC not cooling troubleshooting guide
• Furnace blowing cold air instead of warm
• System cycling on and off every few minutes (short cycling)
• Refrigerant leak (hissing sound, ice on coils, reduced cooling)
• Thermostat malfunction (blank screen, unresponsive, wrong readings)
• Unusually high energy bills indicating a failing component
• Indoor air quality problems (musty smells, excessive humidity)
• Frozen evaporator coil or ice buildup on your outdoor unit

What to Do While Waiting for Emergency HVAC Repair

While you wait for our technician to arrive, here are steps you can take to stay safe and minimize damage:

If Your AC Fails in Summer Heat:

1. Turn off the thermostat to prevent further damage to the system
2. Close blinds and curtains on sun-facing windows to reduce heat gain
3. Use portable fans or ceiling fans to circulate air
4. Stay hydrated — drink water frequently
5. Move to the lowest level of your home (heat rises)
6. If you have elderly family members, infants, or pets, consider going to a cooled location if indoor temps exceed 85 degrees
7. Avoid using the oven or stove, which adds heat to your home

If Your Furnace Fails in Cold Weather:

1. Check your thermostat batteries and settings before calling
2. Check your circuit breaker — a tripped breaker is an easy fix
3. Close off unused rooms to concentrate heat
4. Use space heaters safely (keep 3 feet from flammable objects, never leave unattended)
5. Layer clothing and use blankets
6. Let faucets drip slightly to prevent pipes from freezing
7. Never use a gas oven or stove for heating — this creates carbon monoxide risk

If You Smell Gas:

1. Do NOT flip any light switches or create sparks
2. Leave the house immediately with all family members and pets
3. Call 911 from outside the home
4. Call your gas utility company
5. Call us once the area is safe for repair

Common Emergency HVAC Problems in Central Texas

Central Texas puts unique demands on HVAC systems. Our hot summers, occasional freezing winters, and high humidity create specific problems that we see regularly:

Summer AC Emergencies (April - October):

• Frozen evaporator coils — Often caused by low refrigerant, dirty filters, or restricted airflow. Learn more about AC freezing up.
• Compressor failure — The compressor is the heart of your AC. When it fails, your system cannot cool. Extreme heat and electrical surges during storms are common causes.
• Capacitor burnout — Capacitors help start your compressor and fan motors. Texas heat shortens their lifespan significantly. This is our single most common emergency call.
• Refrigerant leaks — Coils develop leaks over time, especially in systems over 10 years old. Read about refrigerant costs.
• Condensate drain clogs — High humidity means more condensation. Clogged drains cause water leaks inside your home. Learn about AC leaking water.

Winter Heating Emergencies (November - March):

• Ignitor failure — The hot surface ignitor is the most common furnace failure point. Furnace not turning on?
• Heat exchanger cracks — A cracked heat exchanger is a serious safety hazard that can leak carbon monoxide. Requires immediate shutdown and professional inspection.
• Gas valve problems — Gas valves can fail or stick, preventing your furnace from heating.
• Blower motor failure — When the blower motor fails, heated air cannot circulate through your home. Furnace blowing cold air?
• Thermostat failure — Dead batteries, wiring issues, or a failed thermostat can leave you without heat. Thermostat troubleshooting tips.

How to Prevent HVAC Emergencies

Most HVAC emergencies can be prevented with regular maintenance. Here are steps you can take:

1. Schedule bi-annual maintenance — Spring AC tune-up and fall heating tune-up catch problems before they become emergencies. Learn about our maintenance plans.
2. Change your air filter regularly — A dirty filter is the number one cause of HVAC problems. Change it every 1-3 months. How to change your furnace filter.
3. Keep your outdoor unit clear — Maintain at least 2 feet of clearance around your outdoor condenser or heat pump unit. How to clean your AC condenser.
4. Watch for warning signs — Strange noises, unusual odors, rising energy bills, and inconsistent temperatures are early warning signs.
5. Know your system’s age — HVAC systems typically last 12-20 years. If yours is approaching that age, plan for replacement before an emergency forces your hand. Use our HVAC Age Decoder to check.
6. Prepare for seasonal transitions — How to prepare your AC for summer and how to winterize your home.

Frequently Asked Questions About Emergency HVAC Repair

How much does emergency HVAC repair cost in Killeen, TX?

Emergency HVAC repair in the Killeen, Temple, and Central Texas area typically costs between $150 and $700 for most common repairs. A diagnostic service call is $75-$150. Simple fixes like a capacitor replacement run $150-$350, while major repairs like a compressor replacement can cost $1,200-$2,500. Texas Temp Masters provides upfront pricing before any work begins so there are no surprises. Use our cost estimator tool for a more specific estimate.

What should I do if my AC stops working in the middle of the night?

If your AC stops working at night during summer, first check your thermostat (replace batteries if needed) and your circuit breaker. If those are fine, turn the system off to prevent damage and use fans to stay cool. Close blinds on sun-facing windows, stay hydrated, and call Texas Temp Masters first thing in the morning at (817) 704-0706. We offer same-day service Monday through Friday to get your system running quickly.

How quickly can you respond to an HVAC emergency?

Texas Temp Masters provides same-day emergency service Monday through Friday, 8AM-5PM. When you call, our dispatcher evaluates the urgency and sends the nearest available technician. For true emergencies like complete system failure during extreme weather, gas leaks, or safety hazards, we prioritize your call.

Is it worth repairing my old AC or should I replace it?

As a general rule, if your AC is over 10-12 years old and the repair costs more than half the price of a new system, replacement is usually the better investment. Newer systems are significantly more energy efficient, which lowers your monthly utility bills. Use our Repair or Replace Calculator to run the numbers for your specific situation. Read more in our blog: AC repair cost guide and AC replacement cost guide.

Why is my AC running but not cooling the house?

Several things can cause an AC to run without cooling: low refrigerant from a leak, a dirty or clogged air filter, a frozen evaporator coil, a failed compressor, a bad capacitor, or a malfunctioning thermostat. Start by checking your air filter — a clogged filter is the most common and cheapest fix. If the filter is clean, call a professional. Read our full troubleshooting guide: AC not blowing cold air.

Do you service all HVAC brands?

Yes. Our technicians are trained to service all major HVAC brands including Carrier, Trane, Lennox, Goodman, York, Rheem, Daikin, American Standard, Bryant, Amana, Ruud, Heil, Tempstar, and more. We carry common parts for all major brands on our trucks. Use our HVAC age decoder to look up your system’s manufacture date by serial number.

What is the most common emergency HVAC repair?

In Central Texas, the most common emergency AC repair is a failed run capacitor. The extreme summer heat puts enormous stress on capacitors, causing them to fail — often during the hottest days when your system is working hardest. Capacitor replacement is a relatively quick and affordable repair, typically $150-$350. The most common furnace emergency is a failed hot surface ignitor, which costs $150-$350 to replace.

How can I prevent HVAC emergencies?

The single best way to prevent HVAC emergencies is regular professional maintenance — a spring AC tune-up and a fall heating tune-up. During these visits, technicians catch worn parts before they fail. Between professional visits, change your air filter every 1-3 months, keep your outdoor unit clear of debris, and watch for warning signs like strange noises or rising utility bills. Learn about our maintenance plans. Read our maintenance cost guide.

Do you charge overtime or after-hours fees?

No. Texas Temp Masters does not charge overtime fees during our standard service hours (Monday through Friday, 8AM-5PM). The price we quote is the price you pay. There are no hidden fees, trip charges, or premium rates for emergency calls during business hours.
