Question by lisa33772: what causes a central air conditioning unit to freeze up?
I have a central air conditioning unit that is probably 12 years old or so.I recently had a situation where my central air would run constantly without shutting off.The air temperature in my house was 80 degrees and it was still running.Well,I also recently found out that the coils in the ac unit were completely frozen solid along with the hoses that ran from outside at the unit,all the way inside to my furnace.Id like to know what causes these coils and pipes to freeze and how does one keep it from happening again?

Every once in a blue moon, cold temperatures lead to things freezing. Is there something that may be causing cold temperatures in or around your A/C? That may be the problem.

Again, sometimes it’s that cold weather… maybe put it next to your heater and crank it up all the way?
