When your central air conditioner is not keeping your house cool enough in the summer, it could be due to a shortage of coolant in the system. A shortage of coolant will prevent the system from cooling the air enough and fixing this problem usually requires getting an AC recharging. Here are three signs that your system may need to be recharged:
The Air Blows As Normal, But Isn't Cold
The first sign that your AC system might be low on coolant is if it seems to be working fine, but is not blowing cold air. In other words, if there is a sufficient amount of air coming from your register vents, there is likely a problem with the coolant level if the air is not cold.
When the coolant level is low and everything else is working fine with a central air conditioner, you will never be able to cool your house to the desired temperature. The coolant in the system is used to extract heat out of the air, and this cannot happen if there is not enough coolant in the system.
Changing The Filter Doesn't Help
Before you rush out and call a repairman to fix the problem, you may want to check the air filter in the system. If the air filter is dirty, this too could be preventing the system from working properly. If you find that there is a lot of dirt in the filter, replace it with a new one. If you do not see a difference in the temperature of the air after changing the filter, this is another sign that the coolant level is probably low and needs to be recharged.
There Is Frost Buildup
The third sign to look for is frost buildup. When the coolant level is low, it is typically because there is a leak somewhere in the system. If the coolant leaks from the system, it often causes freezing. This can occur anywhere on the system, and it is a sure sign that there is a leak.
Whenever a leak is present in an AC system, the coolant will come out and will not be able to cool the air. If there is a leak, it must be fixed before the system is recharged.
If you believe that your system needs to be recharged, contact a company that offers central air conditioner repair. They can determine if this is the problem, and they will also be able to get the system fixed quickly.Share
