Heating and Cooling Myths Debunked

by | Nov 12, 2020

Our pros at Global Cooling know a thing or two about HVAC systems and what makes them tick. Unfortunately, many homeowners have a misguided understanding of what their HVAC units need to get through the various seasons.

Our goal is to equip you with some knowledge and debunk some common misconceptions so you can keep your energy costs low! Let’s start with tip number 1!

#1: Bigger is Better

When it comes to your HVAC unit, bigger does not equal better. The size of your HVAC unit whether it’s an air conditioner or a furnace is meant to correspond with the size of your home. If it’s too big, it’s common for your home to feel uncomfortable because your home is heating or cooling far too quickly. Additionally, throughout your home, you may experience uneven temperature spots.

Here in Florida and at Global Cooling, we focus more on air conditioning. Air conditioners are designed to dehumidify the air in your home. If the unit is too large, it will cool your home so quickly that the dehumidifying process can’t work. That will result in a clammy and uncomfortable feeling to the air in your home.

The last problems larger systems are short cycling and shorter lifespans and they are closely related. Since an oversized unit can cool your home very quickly, it will constantly turn off and on. The typical AC is most efficient when it is allowed to run for more than 5 minutes at a time. This also puts more wear and tear on your system leading to shorter lifespans in the long run.

#2: Closing Vents in Unused Rooms is More Efficient

This is a commonly held misconception that at first glance makes a lot of sense. Many homeowners have a room in their home that they don’t need to be cooled all the time. It may seem smart to close the vents there and allow the cold air to flow to other areas of your home. However, this isn’t the best for your system’s long-term health!

The reason is that your system is designed to fit your home. When you close off an outlet for that cool air, you create imbalances in your system. This creates a strain on your air ducts because of higher air pressure. Soon enough, closing your vents can lead directly to an air leak sprouting up in your ducts.

#3: It Doesn’t Matter Where the Thermostat is Located

Your thermostat is one of the key ways for the average homeowner to impact their HVAC unit. It may surprise you to learn that the location of your thermostat is highly important. Your thermostat measures the temperatures around it. Unfortunately, this means that if your thermostat is located by a drafty window or near your kitchen, it can turn off your HVAC unit prematurely due to the different temperatures around the thermostat

#4: Routine Maintenance isn’t Worth It

The last myth we want to tackle concerns about routine maintenance. The typical HVAC unit lasts somewhere between 10 and 15 years. However, that measure includes routine maintenance! Your HVAC units need to be looked at by a professional at least once a year. We can catch simple problems and ensure your unit can work well for its entire lifespan. Ultimately, this is one of the best ways to save money in the long run!
