HVAC: Myth Busters Edition

HVAC: Myth Busters Edition

We’ve all been there at one point. You go on the internet to do a little research – or end up down some rabbit hole on a topic you spontaneously stumbled across and became curious about. You find some information, but something about it just doesn’t seem right. Do you trust it? Is it right? And whether its news or something completely unimportant – you take a little pride when you’re able to bust the myth of reaffirm your initial feelings.

But when the internet leads you wrong, it’s no fun. While the internet is a great resource, there is a lot of bad information out there. Unfortunately, when it comes to HVAC repair, the same is true of our industry. While we’ll never be able to tamp out all the bad information that’s out there, over the years, certain pieces of misinformation gets out there and metastasizes into something of a myth – and that’s what we’re here to tackle today.

Here are some common urban legends and myths we’re here to bust with regards to HVAC. Let’s jump right in.

Myth #1: If your AC is working, it doesn’t need maintenance

This is flatly wrong. Air conditioners can SEEM like they’re running fine but that doesn’t mean that they actually are. The whole point of maintenance to begin with isn’t to fix issues. It’s to find them before they actually become issues. That’s everything from adjustment, fluid transfers, repairs and the like. You can get this work done anytime. You could say – there’s not a bad time to get maintenance work done – unless, of course – your cooling system breaks down!

Myth #2: Top off your refrigerant

There are a lot of people who think that refrigerant is a thing that depletes from your AC, just like a car would burn gasoline. That’s also not true. When an AC is installed or manufactured – it has all the refrigerant that it needs. It’s not an energy source.

Myth #3: Closing vents in rooms you’re not using will save you money

Huge no-no. Actually, it might cost you more money depending on the airflow of your home. Closed vents prevent certain areas from cooling down or warming up. So in a way, you’re tricking your own system into working harder to cool a space half as much. And the harder a system works? The more energy it will use! More energy usage means more money out of your pockets!
