When summer hits New Jersey, a reliable air conditioner isn’t just a luxury—it’s essential. But how do you know when your AC needs more than a tune-up? Ignoring small issues can lead to major breakdowns, higher energy bills, and uncomfortable living conditions. Below, we’ll cover the five most common signs your air conditioner needs repair, what to do if you spot them, and a few AC maintenance tips.
If your AC isn’t cooling properly, don’t wait for temperatures to soar before you make a call. Schedule professional AC repair with Davis Heating & Cooling to get your system back on track.
1. Your AC Is Blowing Warm Air
There’s nothing worse than expecting relief from a blast of cold air and getting warm air instead. This is one of the clearest signs that something’s wrong with your air conditioning unit.
Warm air could indicate the following problems:
- Low refrigerant levels
- A malfunctioning compressor
- Thermostat problems
- Electrical issues within the unit
First, make sure your thermostat is set to “cool” and your filters are clean. If the problem persists, it’s time to call in a professional. Continuing to run your system this way can strain the components and lead to even more costly repairs. If your AC is blowing warm air, act quickly to avoid a total breakdown.
2. Weak Airflow Coming From Vents
If the air coming out of your vents is cool but barely moving, your AC isn’t doing its job effectively. Weak airflow makes it harder to keep your home comfortable and forces your system to work overtime, which means higher energy bills and more wear and tear.
Common causes of weak airflow include:
- Clogged or dirty air filters
- Leaky or blocked ductwork
- Blower motor problems
Keeping up with regular AC maintenance can help prevent airflow issues before they start, saving you money and extending the life of your system. However, if you’re already noticing weak performance, it’s best to schedule a repair.
3. Strange Noises Like Banging, Buzzing, or Screeching
Your AC unit should never sound like it’s falling apart. While a quiet hum is normal, loud or unusual noises signal a mechanical issue.
Listen for these sounds to help pinpoint the cause of the issue:
- Banging or clanking: These sounds may indicate a loose or broken part inside the compressor.
- Buzzing: A constant buzz could mean the problem is electrical or refrigerant-related.
- Screeching: This high-pitched noise often points to a belt or motor issue.
These are all examples of strange AC noises that you shouldn’t ignore. The sooner you address them, the better. Delaying repairs can lead to more significant damage, system failure, or even the need for emergency AC repair.
4. Leaks or Excess Moisture Around the Unit
If you see moisture around your air conditioner, don’t ignore it. While some condensation is normal, noticeable leaks could mean trouble.
Potential causes of a leaky HVAC unit include:
- A blocked or broken condensate drain line
- Refrigerant leaks
- Ice buildup on the evaporator coils
A leaking air conditioner not only reduces system efficiency but can also cause water damage and mold growth. Plus, if the refrigerant is leaking, it can be harmful to both your health and the environment. If you spot pooling water or signs of leakage, call for service immediately.
5. High Humidity Levels Indoors
One of your air conditioner’s jobs is to remove humidity from the air. If your home still feels sticky and muggy, especially during the summer, your AC might not be operating properly.
High humidity indoors can be a sign of the following issues:
- An aging or undersized AC system
- Dirty coils or filters
- Thermostat calibration issues
If you’re struggling with high humidity in your home, call for a professional indoor air quality assessment. Excess humidity can make your living space uncomfortable and promote mold and mildew, which can damage your home and affect your health.
