Common HVAC Problems and How to Handle Them This Summer
It’s summer and the temperature is getting unbearable. After a short walk, you later find an unpleasant surprise sitting in your home–your air conditioner has suddenly stopped working. In times like this, getting professional help is always the best move, but before you make that call, below are some of the most common HVAC problems, along with the reasons why they usually malfunction.
Understanding These 3 Common HVAC Problems
Working Mechanism: An AC capacitor stores and supplies energy to the compressor, the outside fan and the blower fan of an air conditioning unit. There are two types of capacitors: a start capacitor and a run capacitor. While the former sends energy to activate the AC’s motor, the latter continuously supplies the energy that the motor needs to continue running. When either of the two burns out, other parts of the air conditioner can start malfunctioning.
Problem: Just like batteries, a capacitor can only store a limited amount of power. Once the power supply exceeds its capacity, it can sustain damage until it is no longer able to hold and support a charge. When left unrepaired, faulty capacitors can damage the compressor and other parts of your unit, making it necessary to call for professional help.
Diagnosing the Problem: It’s important to pinpoint exactly why your ac has started malfunctioning, especially since all common air conditioning problems require specific intervention. Once the capacitor fails to hold a charge, you can hear a distinct clicking or humming sound from your AC unit. Also, the air conditioner may automatically shut down shortly after being turned on.
Tip: You should not attempt to manually replace the capacitor since it is dangerous. In case of faulty capacitors, always ask for professional help.
Clogged Drain Lines
Working Mechanism: An AC drain line has a vital role in maintaining ideal humidity levels in your home. To filter moisture from the air, an AC unit uses an evaporator coil that has a drip pan, which collects water that flows through the AC drain line. A drain line is a pipe that deposits water outside your home.
Problem: Clogged drain lines have become one of the most common AC problems of homeowners. Just like its filter, the drain line of your unit can become clogged with dirt, mold, algae, and mildew that accumulate over time. Clogged drain lines can cause water to backflow inside your unit, potentially damaging other parts of your AC.
Diagnosing the Problem: Clogged drain lines are easy to identify. It typically involves water leakage from your unit, which can compromise other AC components.
Tip: You can save up from ac repairs by using a wet-dry vacuum to clear the blockage from your drain line.
Working Mechanism: Refrigerants are the heart of your AC unit. Enclosed within the AC coils, a refrigerant is a fluid mainly responsible for dehumidifying air. Once the AC starts operating, the refrigerant changes from liquid to gas to absorb indoor heat. The compressor then converts the refrigerant back to its previous state to facilitate continuous heat absorption.
Problem: Refrigerant leaks are common HVAC problems that need to be addressed by a technician. The leak is usually due to a low supply of refrigerant, which cannot properly facilitate chemical processes involved in dehumidifying air. Since it is not capable of completing the evaporation and condensation process, liquid becomes trapped in the coil, which in turn causes leakage.
Diagnosing the Problem: If there is leakage in your unit and the temperature in your home incessantly fluctuates, your refrigerant is probably low in supply.
Tip: It’s not enough to add a refrigerant to address your unit’s problem. Once refrigerant leakage is in place, you should have your AC repaired and tested by a trained professional.
Common HVAC problems can cause unexpected stress in the household, but with a proactive approach, you can easily identify the main root of the problem and decide whether or not your AC calls for professional help.
