Birmingham Air Conditioning Repair:  Signs You Need an AC Recharge

Posted by: R Vines on March 9, 2015

Summer isn’t just the time for people to start flocking to nearby Vulcan Park or a Birmingham Barons Game; it’s also the peak season for home air conditioning in Birmingham, Alabama. To survive this time without having to buy brand new AC units, you should know how to care for and maintain your home’s cooling systems and when needed, call for reliable air conditioning repair from Birmingham professionals like Service Tech Heating & Air Conditioning.  When you inspect your AC, be on the lookout for signs that you might need to recharge the coolants.

Coolant Refill Needs

It’s important to note that from the outset, your air conditioner’s coolant or refrigerant never goes bad over time, so you don’t have to replace or refill it because of chemical composition alone. However, there are many problems in the AC’s mechanical parts that can cause the coolant to leak such as matted coils, worn-out valves, and even poor design.  These are sealed systems that should not leak.  Filling the system with more Freon without finding and repairing the leak is not advised.

Checking the Thermostat

The first thing to inspect if you think you might need a coolant refill is the thermostat. Start by setting the temperature to 85 and wait about half an hour, then readjust it to 60 and wait for the unit to run. If the house cools efficiently, you have little to worry about; otherwise, if it takes a lot of time, there might be little coolant left to do the job properly.

Inspecting the Vents

You should check up on your central AC’s vents to find out if there might be indicators of problems:

If the vents are blowing room-temperature air, or warm air, rather than cold after you clean the thermostat and reset the unit, this is a sign that your coolant might be out of charge in the air conditioner. You check this by holding your hand in front of the vents and feeling for warm air. Give the system at least 15 minutes to see if maybe it was just residual air coming out of the vent system as it makes its way throughout your home. If the air still isn’t cold, it is a sign that you could need to call a technician for a professional inspection.

Call the Pros

If after these tips, you believe that your coolant does need refilling, call up the professionals for a final diagnosis so that they can do the work themselves. Never attempt to perform a refill on your own, as you might be voiding your warranty or risking damage to you or your unit.
