Why Are HVAC Myths Increasing?

HVAC myths are common, and many homeowners still believe them for various reasons. Changes in technology, unclear information, and habits passed down over time all play a role. Here are some key reasons why these myths are spreading:

• Outdated Information: Many myths stem from outdated HVAC practices that are no longer applicable to modern systems.
• Word of Mouth: Advice from friends, family, or neighbours is often trusted, even if it’s not accurate.
• Marketing Confusion: Some HVAC companies unintentionally add to the confusion with unclear or misleading claims.
• Complex Technology: HVAC systems involve technical details that can be hard to understand without expert knowledge.
• DIY Assumptions: Many homeowners attempt to handle HVAC issues themselves without a complete understanding, which can reinforce incorrect beliefs.

These factors combined make myths grow faster than facts. Understanding why they spread is the first step toward breaking them.

Top 10 HVAC Myths and the Truth Behind Them

Many homeowners mistakenly believe common myths about their HVAC systems. This can lead to poor maintenance, higher energy bills, and less efficient systems. Understanding the truth behind these misunderstandings is crucial to ensuring your heating and cooling system performs optimally and lasts longer. Let’s dive into some of the most widely believed misconceptions and separate fact from fiction.

1. Cranking Up The Thermostat Heats The House Faster

Turning the thermostat up to a higher setting will make your home warm up faster.

Fact: HVAC systems heat at a consistent rate, regardless of the thermostat setting. Cranking up the thermostat wastes energy and can cause the system to work harder than it needs to. Maintaining a consistent and comfortable temperature setting is the best way to ensure efficient operation and prevent unnecessary energy consumption.

2. Closing Vents in Unused Rooms Saves Energy

Closing vents in unused rooms will save energy by directing more airflow to the rooms you do use.

Fact: Closing vents can create pressure within your HVAC system, causing it to work harder to push air through the system. This can lead to inefficiency and even cause long-term damage. It’s better to leave vents open to ensure balanced airflow and allow your system to run as it was designed to.

3. Changing Filters Once a Year is Enough

Changing your HVAC filter just once a year is sufficient.

Fact: Air filters should be changed every one to three months, especially during high-use seasons. A dirty filter restricts airflow, forcing your HVAC system to work harder and reducing its efficiency. Keeping filters clean ensures better air quality, increased energy efficiency, and extended system life.

4. HVAC Systems Don’t Need Maintenance

If your HVAC system is working fine, it doesn’t need maintenance.

Fact: Regular maintenance is crucial for keeping your HVAC system running smoothly. Without proper maintenance, minor issues can grow into larger, more expensive problems. An annual tune-up helps catch issues early, improves system efficiency, and extends the lifespan of your heating and cooling system. If you want to protect your system and avoid costly repairs, schedule professional tune-ups with the HVAC Services in Surrey team today.

5. Air Conditioning is Only for Summer

Air conditioning is only needed during the hot summer months.

Fact: Air conditioners help regulate indoor temperature and improve air quality year-round, mainly in humid climates. Using your AC in spring or fall can help manage indoor humidity levels, preventing mold and enhancing comfort. Running the AC periodically throughout the year also ensures the system stays in top working condition.

6. HVAC Systems Are Too Expensive to Upgrade

Upgrading your HVAC system can be a significant financial burden and may not be worth the investment.

Fact: While the upfront cost of upgrading to a more energy-efficient system may seem high, the long-term savings on energy bills can make it worthwhile. Modern systems use less energy, operate more efficiently, and may qualify for rebates or tax incentives. Upgrading your system can improve comfort and help save money over time.

7. Heat Pumps Don’t Work In Canadian Winters

Heat pumps are often ineffective in cold climates, such as Canada.

Fact: Heat pumps are designed to operate efficiently in a wide range of temperatures, including those found in Canadian winters. Modern heat pumps are built to operate in sub-zero temperatures and can effectively heat your home even in the coldest months. 

Additionally, they provide both heating and cooling, making them a versatile and energy-efficient choice for year-round comfort.

8. Duct Cleaning is Always Necessary

Duct cleaning is a must for every HVAC system.

Fact: Duct cleaning is essential when there’s a visible buildup of dust, debris, or mold, but it’s not something that needs to be done every year. If your ducts are relatively clean and there are no signs of air quality issues, duct cleaning can often be skipped. However, if you have allergies or pets, more frequent cleaning may be beneficial for maintaining air quality.

9. Changing Filters Once a Year is Enough

Changing your HVAC filter just once a year is sufficient.

Fact: As mentioned earlier, filters should be replaced regularly; every 1-3 months, depending on usage. Filters trap dust, dirt, and allergens, and if left unchanged for too long, they can block airflow, causing the system to work harder. Clean filters ensure your HVAC runs efficiently and your indoor air remains clean and healthy.

10. DIY HVAC Repairs Save Money

          DIY repairs are a good way to save money on HVAC system issues.

Fact: DIY repairs may seem like a way to save money, but they can often cause more problems than they solve. Improper repairs can lead to system damage, void warranties, and result in higher repair costs in the long run. It’s always best to hire a qualified HVAC professional to handle repairs, ensuring your system is fixed correctly and working efficiently.

Final Words

Understanding the facts about HVAC systems can significantly impact comfort, efficiency, and cost savings for homeowners. By moving past outdated ideas and focusing on accurate information, you can protect your system, improve performance, and extend its lifespan. Regular maintenance, informed upgrades, and smart operation ensure your home stays comfortable year-round without unnecessary expenses. Staying informed helps you make confident decisions and get the most value from your HVAC system.
