HVAC systems can sometimes be viewed as complex, but get the right tools, and a new world of home comfort and energy savings will open up to you.
Without an HVAC multimeter, you can only measure the basic temperature readings, or when there are simple issues like a burnt-out outdoor light. With just a multimeter, you can track down and pinpoint an indoor air leak during those cold winter months.
However, with a multimeter, you’ll be able to make better and more confident home improvements, saving you time and money. You will be able to stop worrying about silly things like having to throw away a batch of cookies every time your oven burns out, or fill the cracks in your tiles with silly putty anymore.
