Common AC Problems: Why My Air Conditioner Isn’t Cooling?

As summer approaches, the efficiency of air conditioning units becomes increasingly critical. However, there can be moments of frustration when the once-trusty air conditioner fails to provide the desired cool comfort. There can be several reasons why an air conditioner might not be cooling as expected, ranging from simple maintenance issues to more serious mechanical problems. This article explores common summer HVAC problems that may be impacting your air conditioner’s performance.

1. Dirty or Clogged Filters

The most common cause of an underperforming air conditioner is a dirty or clogged filter. Filters are designed to remove particulates like dust, pollen, and pet dander from the air. Over time, these particles accumulate on the filter, restricting airflow. This reduced airflow can significantly impact the efficiency of the cooling system. Replacing or cleaning the filter regularly, especially during high-use, Florida summer months, can rectify this problem.

2. Low Refrigerant Levels

The refrigerant is a critical component of your air conditioner’s cooling process as it absorbs heat from your home and releases it outside. If there is a leak or if the refrigerant levels are low for any reason, the air conditioner will struggle to cool the space effectively. Low refrigerant levels require one of our professional HVAC technician’s attention as refrigerants can be hazardous to handle without proper training.

3. Faulty Thermostat

Sometimes, the issue isn’t with the air conditioning unit itself but with the thermostat. If the thermostat is not calibrated correctly or if its sensors aren’t working, it may not signal the air conditioner to start cooling. Modern thermostats can often be reset or recalibrated, but older models may need replacement.

4. Blocked or Leaky Ducts

The ductwork in your home carries cooled air from the air conditioner to the various rooms in your house. If these ducts are blocked or have leaks, it can significantly reduce your air conditioner’s efficiency. Common causes of blocked or leaky ducts include pests, accumulated debris, or simple wear and tear. A Tony Kelly HVAC professional can conduct a thorough inspection and necessary repairs.

5. Overheating Components

Like any mechanical system, air conditioners consist of several parts that work in harmony. If any of these parts, such as the compressor or condenser coils, overheat or fail, the entire system’s efficiency can be compromised. Regular maintenance can help detect potential problems before they lead to system failure.

6. Poor Maintenance

Air conditioning units, like all appliances, benefit significantly from regular care and maintenance. Inadequate maintenance can lead to a range of issues, from dirty filters and condenser coils to worn-out fan belts and electrical problems. A regular maintenance schedule with one of our professional technicians can ensure your air conditioner operates at peak efficiency.

It is advisable for individuals residing in hot, humid regions to have their air conditioning system serviced professionally at least biannually: a service in the spring to prepare for summer’s heat and another in autumn to ready the system for the chillier winter months. These routine check-ups equip your system to effectively handle the contrasting demands of varying seasons.

How often should you get your A/C serviced?

Nonetheless, there are a few maintenance tasks homeowners can and should perform more frequently to ensure their air conditioner’s optimal operation:

Filter Examination and Replacement or Cleaning: The type of filter your air conditioner uses and the model of your unit will determine the frequency of your filter checks. Filters should be examined monthly and replaced or cleaned according to need. Some filters require replacement every month, while others may only need replacement biannually. A clean filter not only optimizes air quality but also boosts your A/C unit’s performance.

Outdoor Unit Maintenance: Regularly inspect the outdoor component of your air conditioning system to ensure it is free from leaves, branches, and other debris that may inhibit airflow.

Condensate Drain Inspection: Particularly during the humid summer months, routinely inspect your air conditioner’s condensate drain for blockages to avoid water damage and possible mold proliferation. Always remember, having your air conditioning system serviced regularly by one of our skilled HVAC technicians is vital for extending its life, enhancing its efficiency, and preventing expensive malfunctions.
