A iced up system is caused by either airflow issues or refrigerant charge problems. Check for dirty furnace filter, blower issues, or low on refrigerant charge.
My hubby changes filters quite often. He just put a new one in today, after the fact, but I don't think it was that bad.
OK, if filter is OK and air seems to be coming out of the vents OK (after you deice it), then that would point to the last problem---low on refrigerant charge.
We leave the door opened up some most the time for good airflow. he said it was probably the Freon. Can we check that someway?
Not really. Even if you had a guage set, you would need to know what to look for--the proper pressures and this takes training and experience.
OK so we have to call an expert out then?
Yes, but I would thaw it out completely first as it's impossible to read the pressures with it all iced up. I'm guessing it will be down 1-2 pounds at least.
it has been awhile since we have had someone out to check it.
Yeah, sounds like it's time again. Good luck!
What is an approximate cost per pound of refrigerant?
If it's R22 the cost can vary---but I charge $30/lb. The stuff is REALLY expensive now as it is being phased out.
Oh well, I will just go on and call, I am sure he won't be here that soon. Thanks
OHhh, whats the newer version if its being phased out? This unit is11 years old.
R410A. It would have a pink colored lablel or say R410A on the label. No problem. Let me know if you have any other questions. Please don't forget to rate my service. Have a great day!
