Is it hotter than normal outside, or is your air conditioner struggling? If you experience these 5 signs you need AC repair, it may be time for a professional air conditioner inspection.
1. Poor air conditioner performance
Many issues may affect your system’s ability to maintain temperature, including system age, low refrigerant, compressor issues, and airflow restrictions.
2. Frequent cycling or difficulty starting AC
A dirty AC filter, frozen coil, thermostat problems, and failing electrical components can cause short cycling or failure to start.
3. Bad air conditioner smells
AC odors often result from drainage problems, electrical issues, and mold growth.
4. Unusual AC noises
Loose parts, debris in the unit, and motor problems can cause strange noises.
5. Higher energy bills
Old and poorly maintained AC systems consume more power.
Poor Air Conditioner Performance
If your heat pump style air conditioner is not cooling properly, and you’re experiencing weak airflow or warm air blowing from vents, these top culprits could be to blame:
Dirty air filter
Air filters should be replaced every 1-3 months to prevent airflow restrictions.
Blocked or leaky ducts
Uneven cooling and warm rooms indicate that a duct inspection and sealing may be in order.
Dirty coils
Dirty condenser coils cannot release heat, forcing your system to work harder to maintain temperature. Regular coil cleaning by our Yakima AC contractors ensures efficient performance.
Low AC refrigerant
If your air conditioner blows warm or you see ice on the cooling lines, you might need a recharge.
Old or undersized air conditioner
If your system is over 10-15 years old or you’ve added on to your home, it may be time to upgrade your AC system.
Frequent Cycling or Difficulty Starting
If your air conditioner won’t start or turns off and on frequently, look for these common causes:
Dirty air filter
Air filter clogs can cause your system to overheat and shut down.
Thermostat problems
A dead battery or thermostat malfunction can impact AC operation.
Frozen AC coil
Reduced airflow from a dirty air filter, poor heat transfer due to low refrigerant, or setting the thermostat temperature too low for an extended period can cause the evaporator coil to ice over, prompting frequent cycling as it thaws and refreezes.
Failing electrical components
Faulty sensors, capacitors, damaged wires, and tripped breakers may prevent startup. Leave fault tracing electrical issues to a pro to ensure safety.
Bad AC Smells
Odors emanating from your air conditioner may be caused by:
AC drainage problems
Drain lines clogged with algae, mildew, or debris can cause odors and back up into your home, causing damage. If using a wet/dry vac doesn’t clear the drain line, professional cleaning or repairs may be needed.
Electrical issues
A failing motor or overheated wiring can cause electrical or burning smells.
Mold or pests in the system
Mold or mildew on AC coils and ductwork, or dead pests and their nests, require rapid attention. Professional cleaning helps you prevent system damage.
Unusual AC Noises
Ignoring strange air conditioner sounds could lead to costly damage or system failure. Common causes include:
Loose air conditioner parts
Rattling, banging, and clanking sounds point to loose or broken parts, ranging from nuts and bolts to the compressor, fan, or motor assembly.
Debris in AC unit
Rattling and knocking sounds may result from fan obstructions and can be easily identified by inspecting your outdoor unit.
Motor problems
Loud or persistent buzzing or screeching indicates a failing motor. Turn off your unit and schedule a professional AC system inspection ASAP.
Higher Energy Bills
Struggling systems consume more power. If your energy bills are creeping upward, consider whether these driving factors may apply to your home AC:
Old, inefficient air conditioner
Systems lose efficiency over time, using more power to cool. Replacing your air conditioner with a newer, higher SEER unit could offer substantial monthly savings and greater comfort.
Insufficient maintenance
A combination of a dirty air filter and coils, low refrigerant, and worn, poorly lubricated parts forces your system to run longer and harder to maintain temperature. Routine spring maintenance ensures all parts perform optimally, providing energy-efficient cooling all summer long.
