You’d like to enjoy your home in the coolest and most comfortable way possible. It isn’t fun to have to deal with the heat of the summer, along with three, four or five more of your friends or family members.


The summer heat can be so harsh and consistent, that’s it’s stifling, especially when you have an air conditioner that’s had a meltdown. That’s why you have to do your best to ensure that you keep your air condition in the best working condition possible. You don’t want it to freeze, but if it does, we can show the reasons for that happening and what you can do to prevent it from happening again. Pay attention.


Your air conditioner may freeze if…

  • It is running low on refrigerant or if there is insufficient charge in the fluid. If you have a leak, this may also be a cause of the problem, because the moving parts may be rubbing together or starting to vibrate, or, because the shoulder joints and fittings are loose. Have a professional test your system out so that any possible leaks, damaged or weakened parts can be identified and repaired.


  • The airflow in the unit is restricted, resulting in the evaporative coils getting dirty and dropping to a below-freezing; the humid air gets frozen around the coils. Another possible reason is that the air filters have not been changed in over 3 months. You have to ensure that you change them at least every 3 months and have the coils cleaned by a professional.


  • The temperature that you choose to run your air conditioner in, can also affect it. The unit may freeze up if you run it on cool days, especially if that day’s temperature drops below 60 degrees Fahrenheit. Try to abstain from doing that so that you can stop your air conditioner from freezing. It can save you money and energy on the costs of your utility bill.
