Correcting These Common HVAC Myths

There are many misconceptions about HVAC systems on the internet. These myths can mislead you to believe inaccurate information about the HVAC system in Mt. Pleasant, SC, home. Below is a list of the most common HVAC myths and how each is incorrect.

Duct Tape Can Seal Duct Leaks

One common myth about HVAC systems is that duct tape can seal a duct leak. The myth suggests that you take duct tape and wrap it around a vent that has developed a crack. While duct tape is waterproof, it’s not airtight.

Over time, duct tape can become brittle and crack from the elements. Additionally, duct tape is a temporary fix and will need to get reapplied soon.

For proper HVAC performance, duct leaks must be sealed with sealants specifically made for HVAC systems. If your ductwork has cracked or deteriorated, it’s time to contact a professional HVAC technician to make the necessary repairs.

If the HVAC System Isn’t Broken, Don’t Fix It

Although this may sound like good advice, it’s not true. A properly maintained HVAC system will run more efficiently and save you money in the long run. For example, a dirty coil can reduce your HVAC system’s efficiency, which leads to higher energy bills.

A dirty filter also reduces airflow, which also affects heat distribution. If your filter is dirty, you must replace it before the HVAC system can run efficiently.

Dirt and dust can also restrict airflow, which leads to higher energy costs. Check your filters regularly, and clean or replace them as needed.

The Bigger the HVAC System, the Better It’ll Perform

HVAC systems indeed come in a variety of sizes. However, the size of your HVAC system doesn’t determine its performance. An HVAC system’s efficiency depends on several factors.

The factors include proper sizing, installation and maintenance of the unit. If you have an HVAC system that’s too small for your home, it won’t remove humidity and circulate cool air in all the rooms.

On the other hand, an oversized unit will turn on and off frequently while not cooling or warming all of the rooms in the home. If you’re unsure how much capacity you need, contact a professional HVAC technician to correctly size your system.

A Denser Air Filter Is Always Better Than a Less Dense Air Filter

Air filters can come in a high-density or low-density format. While the denser filter may trap more allergens and pollutants, it may also restrict the airflow through the system. Your should use the MERV-rated filter that the manufacturer recommends for your particular HVAC system.

Anyone Can troubleshoot an HVAC System Without Being a Professional

In some cases, you may believe they can troubleshoot an HVAC system. However, there are many variables to consider when it comes to troubleshooting an HVAC system. For example, you may not know what you’re looking for and end up misinterpreting the problem.

A skilled HVAC technician can identify a potential problem with your system and offer a solution. While you can attempt to diagnose the problem, it’s best to contact an HVAC technician for guidance.

Closing a Vent Saves Energy

Closing a vent won’t save energy. Closing the vent can cause your HVAC system to work harder and consume more energy.

Typically, the HVAC system will provide airflow to all rooms. If one vent gets blocked, the HVAC system will work harder to move air through the other vents.

If you suspect that your HVAC system is having issues, don’t hesitate to call a skilled professional to help. A trained HVAC technician can identify the source of the problem and perform necessary maintenance. For more information about HVAC services, contact the team at M & B Heating and Air.
