When your AC is not cooling it’s time to do some simple troubleshooting.  First is to check that the power is on to the building, then check that the thermostat is set to the “cooling” function, this will vary depending on the type of unit.  Manual thermostats will usually have a physical switch while a digital thermostats will have a screen where the setting may be in text or an icon. Many Maryland towns like Annapolis, Crofton, Glen Burnie or Bowie will have apartment buildings which share Heating and Cooling units, however the thermostats will be individual to each dwelling.  The outdoor portion of cooling system may be shared and may be on the ground or on the roof. 

In a single home, residential system the outdoor unit is normally on the ground and is another good place to do your basic troubleshooting.  The area around the unit should be clear.   The image below shows a common condition when a home has been empty for a time. This can even be deceiving because the view is so obstructed that the second air conditioning outdoor unit is obscured by the extreme overgrowth.  When you look closer you find a second unit which is covered on all sides except the very top of the unit.  When checking residential home’s AC units that have been foreclosures or empty for a time it is best to check carefully.  Our service areas of Annapolis, Bowie, Crofton, Pasadena, Laurel, Glen Burnie, Davidsonville and College Park MD had many foreclosures in their towns.  This second image shows the secondary cooling unit, which could not even be seen from the first vantage point.

It must be noted, however, that recharging your AC is a temporary fix to a likely bigger problem. If your system is indeed missing refrigerant, your AC system has a leak and needs to be inspected and repaired with a certified mechanic. Refrigerant does not evaporate in an airtight system so air is leaking in. While there have been recent reports of this procedure being completed at home, it is still considered a more professional repair, as it contains work with hazardous liquid and is best left for a certified mechanic.

Recharging your AC means adding more refrigerant to your AC system to allow the air to start blowing cold again. Freon is a well-known liquid refrigerant that works with the AC system to help keep the air in your car cool. Note: Some older vehicles cannot have their AC recharged. These vehicles generally fall before the year 1995 and use an R12 refrigerant no longer made. The only option is AC replacement. Method 1 of 1: How to recharge your AC Because of the sensitivity of this procedure, we will be explaining how to use the AC recharge kits for this procedure. They have shown to be the most effective and the safest option in comparison to trying to repeat a mechanic’s role at home. AC dispenser with trigger and low side gauge Refrigerant (12-28 ounces, depending on vehicle requirement. This information is located on the underside of the hood). Safety glasses and gloves Tip: Always wear safety glasses when performing work under the hood. It is especially important to be careful to not get any refrigerant on your skin as it freezes quickly and is very painful.

Please be sure to follow all instructions that are included with your AC recharge kit and read every canister’s warnings carefully. Step 1: Turn on your AC. Start your car and turn your AC to Max or High. Step 2: Determine if AC compressor is engaging. An AC compressor is a device driven by the accessory belt that converts the refrigerant from liquid to gas. The compressor has a clutch at the end of it that should be spinning with the accessory belt when the AC is on high. Look for these pulleys moving. If the clutch on the compressor is indeed engaging, then it is likely that the system is low on refrigerant, especially if the air is still blowing slightly cold. You will still want to move ahead with testing the pressure before adding refrigerant. If the clutch is not engaging the compressor, then the AC system is either very low on refrigerant, there is an electrical problem, or the compressor itself has failed. Adding more refrigerant after pressure testing will allow you to know which of these the cause is.

Step 3: Test the pressure. To do this, turn the vehicle off and locate the low side pressure port. The low side pressure service port is generally located on the passenger side of the engine bay. It will have a black or grey cap on it with the letter “L”. Tip: If you are having a hard time finding it, try locating the two aluminum pipes that are coming out of the firewall (the metal wall behind the engine) and trace the larger diameter pipe until you find the service port. Step 4: Attach the recharge hose from the kit. To do this simply place the quick connect fitting, found on the end of the recharge hose, over the port and push down firmly until you hear it click into place. Be careful not to pull the trigger at this time as this will release refrigerant from the AC system into the atmosphere. Step 5: Restart the vehicle. Restart the vehicle and make sure the air conditioner is on the highest settings. Begin to monitor the gauge by watching for the AC compressor to engage the clutch.

Once the compressor is engaged, if the low side pressure is under 40 psi, it is verified that the AC system is undercharged. You want the reading to be as close to 40 psi as possible. Step 6: Thread the refrigerant can onto the recharge hose. This allows you to slowly top off the AC system with liquid refrigerant. Once the can is installed, hold the can upright and squeeze the trigger for 5 to 10 seconds to add the refrigerant to the system. After you release the trigger check the pressure gauge to be sure you are not overcharging the system. Proceed until you are as close to 40 psi as possible. Step 7: Return to the inside of the car. Using a thermometer, insert it into one of the AC vents on the driver’s side, near the steering wheel, and note the temperature. A fully charged system will blow air as cold as 28 degrees. This can vary slightly depending on ambient temperature as well as whether the vehicle has been stationary. If the pressure is over 40psi, that is considered “high” low side pressure.
