A septic system is something that is easily forgotten until something goes horribly wrong. What should you avoid running down your kitchen sink? Is one type of toilet paper safer to use than another? How often does your septic tank really need to be cleaned? These were just some of the questions that I had about my septic tank after it had backed up and filled my yard with raw sewage. Since then, I have spent hours researching septic systems so that I would not have to go through that again. I have developed my website to make learning about septic systems a little easier for others like me.
If your air conditioner system freezes up, it won't only cause you the inconvenience of temporarily failing to cool down your home's interior adequately. It could also lead to long term malfunctions and bring about the need to buy and install new mechanical equipment or even the complete replacement of an air conditioner unit.
Therefore, preventing freeze-ups is the best way to keep your air conditioner functioning reliably throughout the hot season and for as long as possible. The following are four of the most common causes of an AC freeze-up that you want to prevent to keep your air conditioner in the best possible condition:
The temperature outside becomes too low and the air conditioner continues running
If the temperate on the exterior of your home becomes very low, the air that's being brought into your air conditioner unit can become fairly cold.
Cold air that has not yet been conditioned that's running through your unit can cause your unit's interior pressure to drop very low. Eventually, low pressure and cold air going through your AC can lead to a freeze-up that stops all air flow and all cooling in the unit.
Air is not freely flowing through the system
If the air that's being forced through your unit is blocked somewhere, a freeze-up can occur. Air can become blocked when going through an AC unit because the unit's filter needs to be changed. Also, air flow can be restricted because of blocked vents or because of malfunctions of the evaporator coil.
A freeze-up occurs when warm air is not being exchanged properly through the coil, and this leads to a temperature drop throughout the entire unit. Keeping an air conditioner unit clean and free of dust is important to preventing a freeze-up caused by air flow restrictions.
There is not enough refrigerant in the system
When there is not enough refrigerant in an AC system, the pressure within the system sometimes drops. Lower pressure leads to lower temperatures, so a freeze-up can be triggered by a lack of refrigerant.
Regularly inspecting your AC unit to check for adequate refrigerant levels can minimize the chances that your unit will experience a freeze-up
Mechanical equipment within the AC system stops functioning properly
Various malfunctions in mechanical equipment can also lead to a freeze-up. Some possible mechanical issues that cause temperatures to drop include a broken fan or blower or a refrigerant line with a leak or break.
