When it comes to HVAC systems, there are numerous myths and misconceptions that can mislead homeowners and cause unnecessary worries or improper maintenance practices. Together, we will debunk the most common myths surrounding HVAC systems. By shedding light on these misconceptions, we aim to provide accurate information and help homeowners make informed decisions about their heating and cooling needs.
Myth #1: HVAC systems don’t require regular maintenance
Maintaining an HVAC system is often overlooked, with homeowners assuming that once it’s installed, it will run smoothly without any maintenance. However, this is a myth. Regular maintenance is essential to ensure optimal performance, energy efficiency, and to prevent costly repairs. HVAC systems should be inspected, cleaned, and serviced at least once a year by a professional technician.
Myth #2: Closing vents in unused rooms saves energy
Some homeowners believe that closing vents in rooms they don’t frequently use will save energy. However, this is a misconception. HVAC systems are designed to operate with a specific airflow balance, and closing vents disrupts that balance, causing strain on the system. Instead, consider using zoning systems or programmable thermostats to regulate temperatures in different areas efficiently.
Myth #3: Cranking up the thermostat heats or cools the house faster
Many people believe that setting the thermostat to extreme temperatures will heat or cool their homes faster. In reality, HVAC systems operate at a consistent rate, regardless of the temperature set. Setting the thermostat excessively high or low only leads to wasting energy and potential discomfort. It’s best to set the thermostat to a comfortable temperature and allow the system to work efficiently.
Myth #4: Duct tape is suitable for sealing ductwork
Contrary to its name, duct tape is not an effective solution for sealing ductwork. Over time, it deteriorates, leading to air leaks and decreased energy efficiency. Instead, professionals recommend using mastic sealant or foil tape designed specifically for sealing ductwork. These materials provide long-lasting and airtight seals, ensuring efficient airflow throughout the HVAC system.
Myth #5: Turning off the HVAC system when leaving the house saves more energy
Many homeowners believe that turning off the HVAC system completely when leaving the house for an extended period will save more energy. However, this is not entirely true. While turning off the system can save energy in the short term, it can lead to temperature extremes and humidity issues when you return.
Instead of turning off the HVAC system entirely, consider adjusting the thermostat to a slightly higher temperature in the summer or a slightly lower temperature in the winter. This allows the system to use less energy while maintaining a comfortable environment. Additionally, you can utilize programmable thermostats or smart thermostats to automatically adjust the temperature based on your schedule, ensuring energy savings without compromising comfort. By dispelling this myth, homeowners can make informed decisions about energy-saving practices when it comes to their HVAC systems.
Myth #7: Bigger HVAC systems are always better
There is a common misconception among homeowners that bigger HVAC systems will provide better cooling or heating performance. However, this is not necessarily true. In fact, installing an oversized HVAC system can lead to several issues.
Firstly, an oversized system will frequently turn on and off, known as short cycling, which can result in inefficient operation, increased energy consumption, and unnecessary wear and tear on the system components. Moreover, an oversized system may not adequately dehumidify the air, leading to a clammy or uncomfortable indoor environment.
It’s important to properly size your HVAC system based on the specific requirements of your home. A professional HVAC technician can perform a load calculation to determine the appropriate size for your system, taking into account factors such as the square footage, insulation, climate, and number of occupants. By debunking the myth that bigger is always better, homeowners can ensure that their HVAC system is properly sized for optimal performance, energy efficiency, and overall comfort.

Probably the most common question we are asked about HVAC systems is:
Should I repair or replace my HVAC system?
Many people, including many other contractors, use multiple methods to answer this important question. It could be the personal opinion of the technician at your home, or even his or her mood that day. It could be based on how much someone wants to replace your system.
At Ward PH&A, we believe in data, consistency, and being objective. We know without question that spending $ on repairing old systems is a decision many customers later regret. Therefore, our method for advising to repair or replace your system is based on and an industry-accosted formula that helps consider that knowledge:
The $5k rule… If the cost of the needed repairs on a system (in $) X the age of the system (in years) exceeds $5k, we advise customers to consider replacing their system rather than repairing it.
