How To Operate and HVAC Vacuum Punp – A Beginners Guide

For many of the Do-It-Yourselfer’s out there you obviously are wanting to save yourself a little bit of money but still want to do it correctly, right?  Well, Unless you want to pay an HVAC Technician $65 or more an hour to come do it for you.  There is absolutely nothing wrong with having a Professional take care of it for so you will have some sort of satisfaction and guarantee that it may be done correctly. 

Its a very easy task and doesn’t take very long. You really just need an understanding of the equipment, how it works, and what to look for.  In this guide I give you an easy to understand way to vacuum ( or “draw down” as they say in the industry) your lineset to remove any air or moisture in the copper tubing. Any of these or a combination of these in your lines can cause some serious havoc to your Compressor. I do need to emphasize that many of your HVAC dealers or manufacturers will not cover the unit under Warranty unless its completed by a Licensed HVAC Technician.  Even if you prefer to do it as a DIY’er as long as it’s done correctly, you shouldn’t have any warranty issues or the need to file a warranty claim.

All of the Mini Split Systems that we sell come complete with the Compressor, Air Handler, Lineset Installation Kit, and Remote.  To learn HOW TO install your system, you can start  HERE  .

What Exactly is a Lineset, Do you ask?

How To Install A Mini Split – Part 1

Why We Made Our Decision:

My wife and I needed to make a decision on how we would cool and heat our cabin during the summers and winters to come.  We purchased an 8000 BTU window unit from a local Big Box store in the beginning of the summer months to make some effort to keep us cool. We knew that we wanted to eventually purchase a Mini Split unit to provide both cooling and heating  when we needed it.  The window unit surpassed our expectations for keeping us cool and comfortable, but we knew we needed more.

Due to the affordability and ease of installation, we decided that a Mini Split unit was our best option for our size cabin.  We chose an AUX 12,000 BTU unit which both heats and cools. At less than 500 Square feet of cabin space, some would say a 12,000 BTU was overkill.  The particular unit that we chose is rated to heat and cool up to 600 Square Feet without any problems. This particular unit came with the installation kit which included both line sets, wiring, remote control, and the outdoor compressor and indoor air handler and wall mounting bracket for the indoor air handler.  Many of these units also arrive pre-charged with R410a Refrigerant.
