Talking About Preventative Plumbing Services

Hey there, my name is Russell Tyson. I am going to use this site to educate my readers about services offered by plumbing professionals. When I first started my company, I was unaware of all the necessary plumbing procedures needed to keep the toilets from backing up. My clients often failed to notify me when a toilet started to fail, likely due to embarrassment or a lack of time. Luckily, I was clued into the value of hiring plumbers to perform regular maintenance and repairs on the toilets to keep them in fine shape. I hope to detail those services on this site to inspire others to embrace preventative plumbing procedures.

Tips For Adding Coolant To Your Air Conditioner

by Charlie Clarke

A common reason that a window air conditioner blows warm air is a lack of coolant. Know that a lack of coolant is not a problem that requires getting a brand new air conditioner, and it can easily be fixed by adding more to the system. Here are some helpful tips for doing it correctly.

Identify the Coolant

There are two coolant types that your air conditioner can take. Older air conditioners made before 2010 take R022, otherwise known as Freon. Air conditioner manufactures stopped producing units that use this coolant due to the impact it has on the ozone. Newer air conditioners will use R410A, or Puron, as the coolant of choice for the appliance.

Start by digging up the air conditioner's user manual, since it will list the coolant that the air conditioner takes. The two coolants will not be interchangeable, and putting the wrong coolant into the air conditioner can damage the appliance. When you know the correct coolant, you can buy the appropriate refill kit at a home improvement store. They sell all the accessories to help do this job on your own.

Prep Your Window Air Conditioner

Turn off the power to the air conditioner, since you cannot add more coolant until the unit reaches room temperature. Take the unit out of your window and turn the air conditioner on one of its sides. Remove the cover in order to locate the compressor, which is a tank with two pipes coming from it. These two pipes are the unit's service valve and tap valve. You user manual for the refill kit will have specific instructions regarding how to attach the canister with more coolant to these valves.

Add the Coolant

Adding coolant to the system will require plugging the window unit back into the electrical outlet. Once the canister has been attached, you can turn on your AC at its fastest speed. This forces your air conditioner to remove the coolant from inside your refill canister. You should notice that the air flowing out of the unit is getting cooler, which is a sign that everything is working properly,

Remove the Canister

Be sure to unplug your air conditioner once again before you remove the canister from the compressor. Close all the service lines you used so coolant doesn't leak out, and then put the window unit back where it belongs.

If this doesn't do the trick, there may be a bigger problem going on. Reach out to a local HVAC technician that can help.
