Although HVAC units are massively used in many households, most homeowners don’t properly understand how they function. As a result, people have come up with numerous misconceptions that they believe save up on energy and costs. Unfortunately, these myths can be at the expense of your safety, comfort, and even wallet. In this article, we’re going to bust five common HVAC myths.
1. If It’s Not Broken, There’s No Need to Fix It
HVAC systems have numerous moving parts that need regular maintenance for maximum efficiency and durability. Therefore, simply because your HVAC system works properly doesn’t mean it’s in good working condition. There might be a faulty part that needs repair or replacement, and forgoing it can result in expensive and unnecessary repairs that could have been avoided earlier. It’s wise to hire a professional for your HVAC maintenance as they have the expertise and knowledge required to identify and fix problems.
2. The Thermostat’s Location Doesn’t Matter
Typically, your thermostat’s location makes a huge difference. For instance, placing it directly in front of a window can affect how it gives readings and bump up repair costs. Ideally, the best placement for your thermostat is as follows:
- Away from direct sunlight as it can turn on the AC since it thinks your home is warm.
- Away from kitchen appliances
- On an interior wall
3. You’re Better off Purchasing a Bigger HVAC System
Many people assume it’s normal to have a large HVAC system because most homes contain big units. However, the size of your HVAC unit largely depends on your heating and cooling needs and the size of your home.
Getting a large HVAC unit for a small house isn’t cost-efficient as you’ll spend more money operating and maintaining the system. Alternatively, a small unit for a large home isn’t an ideal option since it will work harder to heat and cool your space, shortening its life span.
4. You Only Need to Change Your Filter Once Every Year
Air filters easily trap dust, debris, and other small particles, resulting in blockages that affect how your HVAC system blows air. Therefore, cleaning or replacing them once a year isn’t enough, especially if you have pets or a large household. Experts recommend changing your air filter at least once a month to improve airflow and reduce the risk of allergies.
5. Turning off Your HVAC System Saves You Money
Many homeowners turn off electrical appliances to lower their energy bills. Although this is useful, it doesn’t necessarily apply to HVAC systems. Switching your HVAC unit on and off increases your energy consumption. This is because the unit uses the most energy during the first few minutes. A great way to save money on energy is by using a programmable thermostat that lowers your HVAC’s settings when no one is at home.
