The hottest summer days were a good opportunity to test the efficiency of your air conditioning unit. You liked the way your unit worked throughout the hot days by keeping your indoor environment cool. However, your air conditioner is still prone to freezing issues despite being reliable during the hottest days. A beautiful summer day will become a blistering one within a short time if your AC freezes up. Your home air conditioner won't make your rooms cool if its evaporator coils are frozen. A faulty component in your residential air conditioner will disrupt it in a big way. So why does your air conditioner freeze up and what's the solution to this problem? Keep reading to learn more.
Refrigerant Leaks or Mechanical Issues
Your residential air conditioner has numerous moving parts that get clogged, broken or stuck sometimes. Its filters get clogged, fans stop moving, refrigerant lines kink and other components leak when the air conditioner isn't properly maintained. Such issues lead to decreased pressure, and this causes the refrigerant to expand a lot and eventually become too cold. Your air conditioner can't regulate temperature if its refrigerant levels are too low.
The air conditioner freezes up when the refrigerant levels get too low. You likely can't use the unit's freezing short guide to fix leak repairs and mechanical problems if you are not a trained air conditioning technician. Get an experienced professional in residential air conditioning to tune up your AC unit regularly to avoid refrigeration leaks, mechanical issues and catastrophic problems that cause your unit to freeze up.
Blocked Air Flow
Humidity settles on the evaporator coils and freezes if the airflow of your air conditioner isn't constant. Clogged or dirty evaporator coils cause insufficient airflow and affect the functionality of your air conditioner. Changing the air filters of your AC unit isn't hard since they are cheap and easy to replace. This will be the last time you experience airflow problems if you tune up your air conditioner every season and keep it clean. Turn off your AC unit and give it time to defrost if its air filters are clogged.
Cool Nights during Summer
The air conditioner you have at home is calibrated to operate within the optimum temperatures set. The efficiency of your residential AC unit deteriorates when the temperature thresholds aren't within the normal limits. Colder nights in the summer throw the air conditioner out of whack since the temperature is beyond what it can accommodate. Get a programmable thermostat to help your AC unit regulate the temperatures. An automatic programmable thermostat will shut down your residential air conditioner every time the temperatures get below 60 degrees.
A freezing air conditioner leaves homeowners frustrated and annoyed, especially during the summer. However, tune-ups and regular maintenance from a competent air conditioning professional will prevent freezing. Residential air conditioners that get inspected regularly are less likely to develop leakages, clogs or mechanical failures.
