10 Signs You Need Emergency AC Repair

10 Signs You Need Emergency AC Repair

There are a few telltale signs you need emergency AC repair. Ignoring them can mean the difference between a relatively easy fix or dealing with a complete breakdown requiring costly repairs or AC replacement. You can reduce the amount of damage by calling an HVAC contractor immediately. Signs of changes in AC performance include:

1. Loud, Unusual Noises

Strange noises you never heard before mean something is wrong with your AC unit. A noise doesn’t always signal an emergency. However, it should be checked out by a professional. These are some noises to be concerned about:

  • Banging: This usually indicates a compressor problem.
  • Rattling: Loosened or detached components may be hitting the metal frame.
  • Screeching: The fan motor is likely malfunctioning or has a bad bearing.
  • Humming: A defective contactor relay switch can cause a loud humming.
  • Buzzing: This can mean the fan blades are imbalanced or refrigerant is leaking from a damaged copper line.
  • Rattling: Loose debris in the outdoor unit can cause rattling, as can a damaged electrical contactor.
  • Clicking: A continuous clicking means the thermostat may be malfunctioning.
  • Hissing: This can signal an air duct leak, a faulty expansion valve, or an incompatible air filter.
  • Bubbling: Excess moisture may be present due to a blocked or cracked drainage pipe.

2. Condensation/Water Leak

A leak from your air conditioner can cause significant damage to the system. Whether there’s more moisture on or near your AC than usual or water is ponding near the drain line, consider it an emergency. The damage from water can quickly escalate and spread to nearby equipment, materials, and furnishings. Therefore, call for 24/7 AC repair near you right away.

3. Reduced Airflow

If the air current from AC vents is weak, the cause can be anything from a clogged air filter to a failing motor. A blocked duct is also a possibility. If not corrected, weak airflow can cause the system to work harder and strain itself. The longer you wait for AC repair, the more damage that can occur.

4. Hot Air from Vents

If your air conditioner is working properly, it should never blow warm or hot air. There are many reasons an AC won’t blow cold air, including a malfunctioning thermostat, refrigerant leak, or another mechanical or electrical malfunction. This kind of problem often precedes a breakdown, so call a technician to diagnose and repair the underlying cause.

5. Short Cycling

An air conditioner normally cycles on and off about two or three times an hour. It may run more often in extremely hot weather. However, if the unit is turning on and off every few minutes, even on days that aren’t so hot, there’s a reason. Eventually, your AC won’t turn on at all, so call for help as soon as you can.

6. Ice on the Coil

The evaporator coil is one of the most common AC components that can freeze. The problem is often discovered when water pools under the air conditioner. If ice forms in your AC, there’s a serious problem affecting how heat is transferred through the system, which can include a refrigerant leak or airflow problem.

7. Electrical Anomalies

If the circuit breaker trips when the AC is on, electrical surges occur during use, or electrical consumption or your utility bill increases, something is wrong with the unit. An electrical problem can short out your AC or cause a fire or shock. Call an emergency AC repair contractor to find the source of the problem and fix it.

8. Warm Spots in Your Home

A well-functioning AC should distribute cool air equally to all parts of your home. If there are hot spots in your home, and there are no windows open or direct sunlight in an affected room, your air conditioner is likely in need of repair. Even subtle temperature differences should not be ignored.

9. Foul Odors

Watch out for burning smells, musty/moldy odors, or the smell of gas or a sweet or chloroform smell indicating a refrigerant leak. Therefore, unpleasant odors can mean your AC unit needs to be cleaned, tuned up, or repaired. The problem can sometimes be in ductwork, which may require cleaning, sealing, or replacement. Call for 24/7 AC repair near you to resolve a potentially dangerous situation.

10. Increased Humidity

For optimal comfort and prevention of mold, indoor humidity should be between 30% and 50%. Feeling stuffy even when the AC is running or being sweaty when not exerting yourself can mean your air conditioner isn’t working. Also, watch for signs of low humidity, such as static electricity, dry skin, and eye and sinus irritation. If humidity is a concern in your home, call an emergency AC repair service.
