Adequate air conditioning is essential for safety and comfort during the warmest months of the year. ACs have a lifespan of 15 to 20 years, but they generally start experiencing problems around age 10. Understanding the potential warning signs of trouble can help you recognize when it’s time to call a professional HVAC technician.

Weak or No Airflow

There are several reasons your AC might be producing little or no air. Before scheduling a repair, check if the HVAC filter is clogged. Change it to see if that fixes the problem. If it doesn’t, it may be due to issues like a failing blower motor or frozen evaporator coil, which requires professional attention.

Short Cycling

Short cycling occurs when your air conditioner shuts off prematurely before it completes a full cycle. It then turns back on, and the short cycling continues. Your home may reach the preferred temperature, but the AC won’t properly dehumidify your space. This is particularly problematic on hot and humid days. If this situation occurs, check to see if the filter is clogged, and replace it if it is. For other causes of short cycling, such as a malfunctioning thermostat, an oversized unit, and a refrigerant leak, you’ll need professional help.

Unusual Noises

If you hear unusual noises coming from an air conditioner, you likely need a repair. For example, a banging noise may indicate a broken part, while a buzzing sound may signal an electrical issue. Never attempt to identify or fix an AC making unusual noises. Turn the appliance off, and call an HVAC expert to schedule an appointment.

Utility Bill Increase

It’s essential to monitor your monthly utility bills, as an unexpected increase may indicate that something is wrong with your system. Before scheduling an HVAC inspection, contact your utility company to ask if there was a rate increase or increased usage. You can gauge from their response whether you need a technician’s assistance. There may be a minor, undiagnosed problem within your system, even if it seems like your air conditioning is working perfectly. Addressing and taking care of the issue promptly prevents it from worsening and requiring an expensive repair.

Abnormal Odors

Strange odors shouldn’t be emanating from your air conditioner. A musty smell may be a sign of a mold problem, while a burning odor could signal an electrical issue. Stop using the air conditioning, and don’t try to find the source of the problem on your own. A skilled team can quickly identify and diagnose the issue to determine an appropriate repair.

Many, but not all, air conditioning problems require the attention of a professional. When in doubt, the safest option is to consult the experts. A knowledgeable HVAC technician can restore cooling and comfort quickly and safely. If you have concerns or require AC repair services, contact Charlton & Hill in Lethbridge, Alberta.
