Whether you own a home or a commercial property, you understand how important HVAC services are. According to ComfyLiving, over 151 million HVAC units are projected to be sold in 2024. This high number shows just how essential our HVAC unit is in heating and cooling the air while keeping it properly filtered and circulating well. However, there are still many misconceptions about HVAC that can lead to performance and mistakes in a system.

Myth 1: Filters Don't Need Frequent Changing

One of the worst things you could do is to not frequently change your HVAC filters. One of the purposes of having such a unit is to properly filter the air. So, when the filtration isn't working, your unit isn't serving one of its main purposes. Changing the filter is also one of the easiest aspects of HVAC maintenance.

As long as it has a clean filter, you and your family can benefit from high indoor air quality. When filters aren't properly cleaned, anything ranging from dirt to mildew and mold can build up in them. When you turn on a unit that has a build-up of such dirt and contaminants, you will inevitably breathe that in. Then, you'll be susceptible to respiratory infections, allergic reactions, asthma, bronchitis, and exposure to other germs circling through the air.

According to our experts, keeping your HVAC filter updated is as simple as changing a filter at least once every three months. Some homes or businesses should change it monthly. Monthly filter changes should be considered if you reside with pets, smokers, people with allergies, or live in a dusty area.

Myth 2: Closed Vents Can Save Money

Many people think they can save money by closing the air vents in rooms that aren't being used. This practice can be more harmful than you think. By closing the air vents, you're making changes in the air pressure and distribution in your ductwork system. As a result, damage, leaks, and excessive noise can result. While you might think you're closing off the air just because the vents are closed, it doesn't prevent the air from coming in through other vulnerabilities in a room, such as cracks.

A better way to control the airflow in different rooms or sections is by using a thermostat. If you have a larger commercial building, you can install a zoning system to control the air in different areas. In your residential space, one thermostat should be able to adequately regulate your entire house, whereas in larger residential spaces, multiple units may be beneficial. A reliable technician should be able to steer you on the right path.

Myth 3: Regular Maintenance Isn't Needed

Don't wait until your system breaks down to call an AC technician. According to Bob Vila, your AC unit needs inspection at least once a year. If your unit is showing other signs of problems like coolant leaks, excessive noise, or bad smells, you should call a professional immediately to check it out. However, with regular inspections, you'll have a technician who can clean and tune up your system while identifying smaller problems before they turn into bigger ones. In other words, regular maintenance can help improve the lifespan of your unit, which can last for about 10 to 15 years, according to our experts. However, if you skip regular maintenance, your HVAC unit can easily deplete before its projected time.

Myth 4: DIY Installation and Repair Is Fine

Just because you're handy around the house doesn't mean you should risk installing and repairing your HVAC system. Your HVAC unit consists of a sophisticated system that requires knowledge, skills, and the right equipment. That's why HVAC services professionals undergo specific training and need proper certifications to do the type of work they do. When you take on this work yourself, you risk not properly installing it or doing more damage by conducting your own repairs. If you attempt to do your own repairs, you can easily void your warranty, violate building codes, and endanger yourself and others.

These are just some of the myths many people have about HVAC systems. Now that you understand the truth behind these myths, you can properly use and respect your unit the way it should be. Leave the installation, updates, and other adjustments to the professionals. For quality HVAC services, call Joe Hurley Inc today.
