The Possibilities Are Endless

When you live in or around Las Vegas, NV, a smooth-running air conditioning system is essential for home comfort. There’s no denying, however, that continual operation during the long summer season puts AC systems to the test. One of the most frustrating problems you can encounter is hot air blowing from the vents. Learn about the most common reasons AC systems fail to produce cool air.

Electrical Problems

Let’s start with the HVAC component that gets your AC system off and running: the start capacitor. Similar in appearance to a battery, it delivers the initial jolt of electricity the system needs to start cooling, then continues to supply power until the cooling cycle finishes. It’s not unusual for the capacitor to wear out in areas where AC systems can run night and day. Whether the problem is the capacitor or faulty wiring, you’ll need help from a qualified service technician to resolve the issue safely.

Refrigerant Leaks

AC systems work best when installed with the correct amount of refrigerant according to the manufacturer’s specifications. Unfortunately, it’s not uncommon for leaks to develop over time. When there’s not enough moving through the system, it’s impossible to maintain a consistently cool temperature. Exposed refrigerant is hazardous to your health. If you suspect a refrigerant leak is causing your AC to blow hot air, don’t try to fix it yourself. Only certified HVAC professionals are allowed by law to recharge the system.

Compressor Overloads

Typically located in an outdoor unit, the compressor in an AC system has a high-pressure limit switch that shuts it down when it gets overheated. This sometimes happens in extremely hot weather, but other problems can result in thermal overloads, including dirty components from lack of regular maintenance.
