The pros share tips to prevent a/c glitches
An A/C constantly turning on and off can indicate a concerning problem. This type of HVAC malfunction typically results from your air conditioner overworking itself. Below are three common causes of short cycling and five methods of prevention.
WHAT IS SHORT CYCLING?
Short cycling occurs when your HVAC unit turns on and off without completing an entire cycle. An A/C cycle is complete when the unit turns off after reaching your desired temperature.
CAUSES OF SHORT CYCLING:
• Electrical malfunctions
This could involve your thermostat, circuit boards, compressor or capacitors.
• Thermostat location
A thermostat placed near a window, air vents or the back wall of your kitchen results in inaccurate temperature data.
• Oversized HVAC unit
Oversized units cool a space too quickly, causing the A/C to turn on and off frequently.
PREVENT SHORT CYCLING:
• Check air filters
A dirty air filter restricts air flow. The more contaminated the filter, the more likely your A/C will turn on and off repeatedly.
• Clean or replace condenser coils
If there is a buildup of debris in the coils, this also restricts airflow. Keeping them clean helps prevent short cycling.
• Clean the register
Dust and dirt build up on vent registers. Use a vacuum cleaner with a crevice tool to keep them clean.
• Check for any refrigerant leaks
Even the most mechanicallyinclined DIYer doesn’t typically possess the tools to locate an invisible refrigerant leak. Your HVAC technician can quickly resolve this issue.
• Inspect evaporator coils
Frozen coils can be caused by poor airflow, a faulty control board or a refrigerant leak. Your HVAC tech can inspect them for you.
