The summer temperature in Rockledge, FL, hovers around 90 degrees on most summer afternoons. In those conditions, your air-conditioned home is a sanctuary. It’s highly satisfying to come back to an indoor space where the air is nice and cool after spending time at the Rockledge Gardens, the McKnight Family Sports Complex, or even your workplace.
So it can be majorly frustrating when you come home to a warm space. You’ll find yourself wondering, “Why is my AC not blowing cold air?”
In this post, Altman’s Cooling & Heating, Rockledge’s expert AC service, will look at some of the possible causes.
Refrigerant Leak
Your air conditioner has different components working together to produce that cool air, but if there’s any that’s arguably the most important, it’s the refrigerant. It’s not a physical component, but it does the bulk of the magic by absorbing heat from your indoor space.
If there’s a leak in the refrigerant lines, your AC will lose some of its capacity to produce cool air. If the leak goes on long enough, the AC will stop producing cold air completely.
One clear sign to watch for that indicates low refrigerant levels is a frozen evaporator coil. Shut down the unit quickly and call in an expert HVAC technician to prevent costlier damage.
Thermostat Malfunction
The thermostat tells your AC when to start a cooling cycle. If it is broken or not reading your indoor temperatures correctly, it will fail to communicate properly with your AC unit. This will lead to a lack of cool air.
Similarly, if you’ve calibrated the thermostat incorrectly, your air conditioner may not produce cold air. Many homeowners in Rockledge, FL, asking, “Why is my AC not blowing cold air?” often find out that the problem lies with the thermostat.
Therefore, it’s always a good idea to begin any troubleshooting there.
Clogged Air Filter
When was the last time you replaced your air conditioner’s filters? If you can’t remember, then dirty air filters might be stopping your AC from producing cold air.
Your AC filters trap dust, debris, and other pollutants floating around your space. Over time, they get clogged. If you don’t change them, they will hamper airflow and reduce your AC’s capacity to cool your indoor space.
You should change your AC filters every 30 to 90 days. The exact timeline will depend on the pollution levels in your home. However, changing AC filters that have been in use for more than 90 days will almost certainly improve your unit’s efficiency.
Dirty Evaporator and Condenser Coils
The bulk of the cooling process involves air flowing across the evaporator and condenser coils. If these components are dirty or clogged, your air conditioner will struggle to complete the heat exchange process. You’ll find yourself looking for other ways to stay cool even while your AC is running.
You should keep the surface of these coils clean to ensure optimum performance. For the best result, clean them at least once a year.
Blocked Vents
Blocked air vents will hamper air flow, just like clogged air filters. Many homeowners in Rockledge, FL, ask, “Why is my AC not blowing cold air?” only to find out that they have blocked registers after an inspection.
The air conditioner is producing cold air, but there’s no way for air to exit the vents. Look around AC vents to ensure you haven’t blocked them off inadvertently with furniture, carpets, plant pots, or other furnishings.
Capacitor or Compressor Failure
The capacitor and compressor control the air conditioner’s performance. If they have suffered any damage, you should prepare for costly repairs or even complete replacement.
The capacitor delivers the electrical energy that is required to start your compressor. If it’s faulty or failing, the compressor can’t run.
If the compressor can’t run, the refrigerant can’t move between the evaporator and condenser coils. As a result, your air conditioner will not produce any cold air.
