Q- The air coming out of my vents isn’t as cool as it used to be, and I have noticed that the outdoor unit has ice on it what is wrong?

A- These symptoms are usually an indication that the system in low on refrigerant. A system low on refrigerant can mean a few different things. The most common is that you have a leak. Your system has a closed refrigerant cycle meaning that the refrigerant will change in both temperature and form several times within the cycle, but the amount of refrigerant will never increase or decrease. However, a leak can spring at any point during this cycle. When you are low on refrigerant it is necessary to do a leak search to determine where the leak is and options for repairs.
