We have all inflated a tire at some point, but did you ever forget to put the valve stem cap on? If so, maybe your air leaked out over time, maybe it didn’t. If it didn’t, Murphy’s law says it is a matter of time before it does. Even if you lost a little air in your tire, worst case scenario, you’re changing a tire on the side of the road. Tires aren’t the only things that come with valve caps. You may not have realized, but if you own an air conditioner, walk-in cooler, commercial freezer, or anything else with refrigerants, you have at least one valve cap. Well, we hope you do!!!
If you are new to the air conditioning business, or if you are just aspiring to be a well-informed customer, you should know that missing service valves caps can be detrimental to the customer and the environment when they are missing. Each year, we lose millions of pounds of gas into the atmosphere unnecessarily due to faulty Schrader valves and rotolock valves that are missing caps. Freon prices are constantly changing, and are becoming more expensive by the day. But you can take an active stance in protecting the environment and your wallet with something as simple as checking to ensure the valve caps are in place and TIGHT.
Sometimes, through oversight, we HVAC service technicians can simply forget to put a valve cap back on. It happens, no one is perfect. However, sometimes a service technician has an ulterior motive – repeat business.
A few weeks ago, we arrived on a job at a grocery store, owned by one of our customers we had been working with over 20 years, before we moved to NC six years ago. It was disturbing to find that most of the Schrader valve and rotolock valve caps were missing from the equipment. We knew we were the only company this grocer called prior to us leaving. Tim had spent a long time hunting down the proper caps to fit all of the equipment in the store so that every valve had a cap.
The call was not related to the caps missing, however, this discovery inspired us to want to write this informative post. Faulty valves, generally leak enough Freon to begin causing problems in approximately 6-12 months, depending on the severity of the leak. Checking your valve caps is about as easy as checking the oil in your automobile. And just like the oil, having that cap in place could save you a lot of money in the long run.
To cap it off, we hope you have found this information useful.
