In the Florida heat and humidity, your HVAC system can feel like a lifeline. Fortunately, these systems are built to last. When maintained properly, an air conditioning unit will last about 10-15 years. Like any machine, these systems start needing repairs toward the end of their life cycle. Learn about some of the most common HVAC repairs and the signs that you may need them.
Low Refrigerant
Refrigerant transfers heat to your HVAC system to cool down the air in your home. Without enough refrigerant, your AC system will struggle to keep up with demand, freeze over, and stop cooling your home.
The most common reason for low refrigerant is a slow leak. Over time, your air conditioning system will run longer and longer as it works harder to reach your desired temperature. If you notice this happening, call a professional HVAC contractor before it becomes a major repair.
Bad Capacitor
Your capacitors help the electric components of your HVAC system — the compressor and the fan motor — start and run. These parts naturally wear out toward the end of a system’s life cycle, though it can happen earlier if a system is not maintained properly.
The first sign that a capacitor has gone bad is that air blows from your vents but isn’t cold. You can also listen for a whirring noise from the fan motor and a buzzing noise from the compressor. If they don’t sound like they’re working properly, the capacitor is most likely the culprit.
Clogged Condensate Drain Line
Your HVAC system serves more functions than just heating and cooling. While your air conditioning cools the air, it also dehumidifies your home. These tasks are performed simultaneously with the help of a PVC drain line. Unfortunately, with these drain lines being exposed to the outdoor elements, they can eventually become clogged with algae and debris.
When this happens, your AC turns off as a safety precaution. Clearing out the drain is messy work that’s better done with professional tools. Leave this task to trained HVAC technicians.
Condensing Unit Issues
The outdoor condensing unit of your HVAC system can have a few different issues that revolve around the condenser fan motor and the compressor. You may notice that the condenser fan motor or compressor has stopped running, the breaker is tripped, or the outside unit is making unusual noises.
Issues with these units are typically caused by internal wiring breaking or coming into contact with the outer case or the ground. This will trip the breaker or cause either the condenser fan motor or compressor to stop running. Bad bearings or valves can also cause the system to go bad. If you have bad bearings or valves, you’ll hear screeching, grinding, hissing or whining noises.
These are some of the most common HVAC repairs, but this is by no means a comprehensive list. If your AC is not running properly, Freezing Mechanical can help with the AC repair. Call us at 305-363-7021 or schedule
