Top 5 Common HVAC Issues
Maintaining a comfortable indoor climate is essential for any home or business, and a well-functioning HVAC system is crucial to achieving this. Regular maintenance of your heating, ventilation, and air conditioning (HVAC) system not only ensures consistent performance but also extends the lifespan of the equipment, enhances energy efficiency, and prevents unexpected breakdowns.
Our team at Air Temp has the top five common HVAC issues and how to prevent them.
1) Dirty Filters
Symptoms: Reduced airflow, increased energy bills, and uneven heating or cooling.
Causes: Air filters collect dust, debris, and allergens over time, which can clog and restrict airflow.
Preventive Measures: Check and replace HVAC filters every 1-3 months, depending on usage and the presence of pets or high pollen levels. Opt for high-quality filters that suit your system’s specifications.
2) Thermostat Malfunctions
Symptoms: Inconsistent temperatures, HVAC system not turning on/off, or incorrect temperature readings.
Causes: Faulty wiring, dead batteries, or outdated models can cause thermostats to malfunction.
Preventive Measures: Regularly check the thermostat’s settings and batteries. Upgrade old thermostats to a programmable or smart version for better control and energy efficiency.
3) Refrigerant Leaks
Symptoms: Poor cooling, hissing noises, and ice buildup on refrigerant lines.
Causes: Corrosion of metal parts, improper installation, or wear and tear can lead to refrigerant leaks.
Preventive Measures: Schedule regular professional maintenance to inspect refrigerant levels and line integrity. Promptly address any leaks to prevent system damage.
4) Drainage Problems
Symptoms: Water leaks around the HVAC unit, musty odors, and increased humidity indoors.
Causes: Clogged drain lines or pans and algae growth can impede proper drainage.
Preventive Measures: Clean the condensate drain line with a bleach solution at least once a year. Ensure the line is free from blockages and the drainage pan is clean and aligned.
5) Electrical Control Failures
Symptoms: System not starting, frequent cycling, and erratic operation.
Causes: Corrosion of wires and terminals or wear and tear from frequent system cycling.
Preventive Measures: Inspect electrical components during routine maintenance. Ensure that connections are tight and free of corrosion. Consider installing surge protectors to safeguard the system from power surges.
