Debunking Common HVAC Myths


Debunking Common HVAC Myths

As homeowners, we tend to rely on common knowledge, advice from friends, and the internet to guide our decisions on maintaining and replacing our heating, ventilation, and air conditioning (HVAC) systems. Unfortunately, some of these common beliefs can lead to inefficient use of our HVAC systems, resulting in higher bills and even equipment damage. In this blog, we will debunk some of the most common HVAC myths that are often misleading and potentially harmful to our home’s comfort and safety.

Myth 1: Regular Maintenance is Not Necessary

One of the most common myths about HVAC systems is that they do not require regular maintenance. The truth is that like any other machine, your heating and cooling system is subjected to wear and tear over time. With regular maintenance, homeowners can potentially avoid costly repairs and replacements while keeping their HVAC system in good shape.
Regular HVAC maintenance should include an annual inspection by a professional HVAC technician. This inspection should involve a thorough cleaning of the system and a close evaluation of all components, including the air filter, blower motor, belts and other moving parts, and electrical components.
Additionally, homeowners should check and replace their air filters regularly. A dirty filter will reduce the efficiency of the system and could cause damage to it. Depending on the type of filter, homeowners should replace it every one to three months for optimal performance.

Myth 2: Bigger is Better

Many homeowners believe that the bigger the HVAC system, the better it will perform. This myth is harmful as an oversized system will only lead to higher energy bills and unnecessary usage. Additionally, an oversized system could lead to poor indoor air quality too. By installing a system that is the right size for your home, you can increase comfort and reduce energy costs.

Myth 3: Duct Tape is Suitable for Duct Leaks

When homeowners identify a duct leak in their HVAC system, their go-to solution is duct tape. The truth is that while duct tape is suitable for temporary solutions, it is not an appropriate repair method. Duct tape can only hold up for a short period, especially when exposed to the typical temperature variations and humidity in an HVAC system and ductwork.
A professional repair will be required to fix the problem completely. Your HVAC technician will use aluminum foil tape or mastic sealant for permanent repairs as they are more effective and they have a longer life span.

Myth 4: Windows and Insulation Matter More than HVAC Equipment

While good windows and insulation are essential for reducing energy losses, investing in efficient HVAC equipment will lead to better comfort and indoor air quality in your home. Homeowners who have old or inefficient HVAC systems will experience less comfort and satisfaction even if their home is newly insulated or sealed. Particularly for ACs, homeowners will need a sufficient number of return air ducts which are vital for proper airflow and ventilation. Without them, the system can easily break down and cause other damaging effects.

Myth 6: Thermostat Placement Does Not Matter

Installing the thermostat in the wrong place could lead to poor temperature regulation, especially in multi-level homes. A thermostat should be installed in an area of the home that represents the overall indoor temperature, for example, the main living room, so it can accurately maintain the proper temperature.
Additionally, if the thermostat is located in direct sunlight or near doors or windows, it will read the temperature inaccurately and provide incorrect information to the HVAC system which will cause it to perform inadequately.

Myth 7: High-Efficiency HVAC Systems Means Low Energy Bills

While energy efficiency is important, no HVAC system guarantees low energy bills. Other factors like insulation, installation quality, and ductwork efficiency can impact your energy consumption. Nonetheless, having an efficient HVAC system increases the chance of lower bills, especially when used with good maintenance practices.

Myth 8: No Need to Know Your HVAC Equipment

Knowing the basics of your HVAC system will help you troubleshoot minor issues before calling in a professional. Homeowners should have a basic understanding of the different components of the HVAC system, including the air conditioner, furnace, ductwork, and thermostat. For example, knowing how to change the air filter can help reduce energy waste and improve air quality.
