4 HVAC Myths That Could Be Costing You Money

Jul 8, 2021

We often turn to the internet when we experience HVAC troubles, but there is a lot of misinformation to be found! Be sure to avoid these four HVAC myths to keep your unit running as long as possible and save money all the while.


Myth 1: Set your thermostat to the lowest temperature for faster cooling.


We’ve all arrived from home after a hot summer day in need of some rapid cooling. In an attempt to make your home as cold as possible as soon as possible, you may have set the thermostat to the lowest setting in the past. Regardless of the temperature you set, your air conditioning will work at the same pace, meaning you should simply set it to a temperature of your preference.


Myth 2: Keeping up with filter replacements isn’t important.


It’s easy to overlook the recommended replacement time span for your HVAC filters, but we highly recommend avoiding this mistake. Without routine air filter replacements, particles, dust and dirt are sure to make their way into the air you breathe.


Myth 3: If your AC is working, it doesn’t need maintenance.


If your home has a newer AC unit, you may feel that paying to have it maintained would be a waste. However, routine maintenance now is what will keep your new unit reliable and functional for years to come. Additionally, even if your unit is functional, it’s entirely possible that it isn’t performing at its peak capacity if you haven’t serviced it for a few years.


Myth 4: You should turn off your AC after leaving your home.


On paper, it makes sense why you would want to turn off your AC after leaving for the day. You won’t be at home, so why pay to keep it cool? In our observations, it will end up costing you more since the unit will have to work harder to cool the space back down once you arrive back home. Instead, simply bump up the temperature a few degrees before you leave for the day.

"We had a really great experience! We really will be using him again. They’re a small company, but they service all types of heating systems and air conditioners, too. The company that we’d used before sent out different subcontracted people each time, so we wanted something different. We called Will-Air this time and it was a good experience."

"After being out all day and coming home to a hot house, it was refreshing to get an HVAC company
to pick up the phone. Rob answered and I was able to tell him the inside unit was not running and it was frozen but the outside unit was running fine. He gave me his pricing and a ballpark figure for a new blower motor, if that turned out to be the problem. I gave him the information on the HVAC panel and he said he had a motor if that was it. He arrived Sunday morning, replaced the blower motor and a bad relay switch and two hours later the house was cooling off. He was very knowledgeable and pleasant. He didn't mind my two little boys asking all kinds of questions about his tools and what he was doing. I also thought the repairs were going to cost a lot more than what I paid. We have used several different companies through the years but Rob has been by far the best. We will be using him for all our future HVAC needs for sure and I would recommend him to anyone who asks."
