Your air conditioning unit works hard to keep you cool. However, your AC can malfunction when you least expect it, leaving you uncomfortable during the hottest times of the year. Being able to catch a problem with your air conditioning early on will ensure that the issue is fixed before a complete system breakdown occurs. The good news is that there are 3 things you can look for to indicate that your air conditioning might need some repairs.
1) The air coming out of the vents is too hot.
Hot air blowing when it should be cold is a clear sign that your AC unit should be repaired. There are various reasons why your air conditioner is generating heat instead of cool air. The evaporator coils may be covered in dirt due to a defective air filter, or the condenser on the exterior of your home could be clogged by debris. There also might be damage to the refrigerant lines that is causing a leak. An experienced HVAC technician can easily find the faulty part or source of a leak before making the proper repairs. When you first notice that your vents are only sending out warm air, reach out to an air conditioning repair service for help right away.
2) The air conditioning never turns off.
While it may seem counterintuitive that a running AC unit could be problematic, you should be concerned if your air conditioner doesn't shut off at all during the day. When an air conditioning system is operating normally, the unit will cycle through a few cooling periods every hour, automatically turning off whenever the desired temperature is reached. Air conditioning that never stops could be the result of a bad thermostat, loose electrical wiring, or a broken fan limit switch. A skilled technician can diagnose the exact issue and repair any components that are not working correctly. Ultimately, it's time to contact an HVAC service if you find that your AC continues to engage without stopping.
3) The air conditioner is creating an unpleasant smell.
An odd scent emitting from your air conditioning system is another signal that you need to consult an HVAC professional. This is because a bad AC smell is usually a clue that something is wrong. For instance, if you smell burning rubber, the fan belt may have deteriorated. A musty scent is often a symptom of excessive mold growth in the air conditioner's drain line, while a strong chemical odor might point to a dangerous leak. Since some of the common causes of abnormal smells can be hazardous for your health, it's important to bring in an AC repair service promptly to take care of the root problem before a more serious issue develops.
As the warm weather rolls in, you don't have to suffer without a functioning air conditioner when the problem can be easily fixed.
