Common HVAC Myths Busted: What You Need to Know

HVAC systems play a crucial role in maintaining comfort and air quality in both homes and businesses. However, despite their importance, there are many myths surrounding them, which can lead to misunderstandings and unnecessary expenses. In this post, we set the record straight by busting some of the most common HVAC myths and offering accurate information to help you get the most out of your system.

Myth #1: “Turning the Thermostat Up or Down Quickly Will Heat or Cool My Home Faster”

One of the most common myths about HVAC systems is that adjusting the thermostat drastically will get your home cooler or warmer faster. While it may seem logical that cranking up the heat or air conditioning could speed things up, HVAC systems are designed to operate in a more gradual way.

Modern thermostats and HVAC units have built-in programs that cycle on and off to reach and maintain the desired temperature efficiently. Changing the thermostat temperature suddenly does not force the system to work faster. Instead, it can cause the unit to work harder, increasing wear and tear on your system and potentially raising your energy bills.

What to do instead: Set your thermostat to your desired temperature and leave it there. This ensures your system operates at optimal efficiency, and you avoid wasting energy. A more efficient approach is to install a programmable or smart thermostat, which can adjust temperatures automatically based on your schedule and habits.

Myth #2: “You Only Need to Change Your Air Filter Once a Year”

Air filters are one of the most important components of your HVAC system. They keep your air clean and help maintain airflow. However, many homeowners believe that air filters only need to be replaced once a year. This is far from true.

Over time, your air filter collects dust, dirt, and debris, which can block airflow and cause your system to work harder. This strain leads to reduced efficiency, higher energy bills, and even system breakdowns. For households with pets, allergies, or heavy HVAC usage, filters may need to be changed every 1 to 2 months.

What to do instead: Make it a habit to check your air filter monthly and replace it when it’s dirty. A clean air filter ensures optimal airflow, improving system efficiency and indoor air quality. During peak seasons – especially in summer and winter – it’s essential to check your filters more frequently.

Myth #3: “My HVAC System Doesn’t Need Maintenance if It’s Working Fine”

Another misconception is that if your HVAC system is working fine, it doesn’t need maintenance. While it may seem that everything is running smoothly, HVAC systems need regular maintenance to ensure they continue to operate efficiently and reliably. Just because your system seems to be working doesn’t mean it’s free from underlying issues that could escalate into costly repairs.

Preventative maintenance can catch small problems before they turn into expensive breakdowns. Additionally, regular tune-ups help your system run at peak efficiency, which can save you money on energy bills.

What to do instead: Schedule a professional HVAC maintenance checkup at least once a year. During a maintenance visit, a technician will inspect the system, clean components, check refrigerant levels, and identify potential issues. It’s the best way to keep your HVAC system in top condition and avoid surprise repair costs.

Myth #4: “An Energy-Efficient System Is Always the Best Option”

Energy efficiency is often touted as the number one priority when it comes to choosing a new HVAC system. While upgrading to an energy-efficient unit is beneficial in many cases, it isn’t always the best option for every situation.

If your current system is relatively new and still functioning well, replacing it with a new energy-efficient model might not yield the expected savings right away. Sometimes, upgrading components like the thermostat, insulation, or air filter can improve efficiency without the high upfront cost of a complete system replacement.

What to do instead: Before making any decisions, consider the overall condition of your system. If it’s still operating well and you’re not facing frequent repairs, enhancing your system with energy-saving accessories might be the most cost-effective approach. Consult with an HVAC professional to determine whether a full replacement or targeted upgrades would be best for your home or business.

Myth #5: “HVAC Systems Don’t Affect Indoor Air Quality”

Many people think of HVAC systems as purely temperature control units, but they play an important role in indoor air quality as well. Poorly maintained HVAC systems can circulate allergens, dust, mold spores, and other pollutants throughout your living or workspace.

When filters and ducts are neglected, these contaminants can accumulate in your indoor air, potentially causing respiratory issues and allergies, and affecting overall health.

What to do instead: Maintain your HVAC system regularly, including changing filters and having ducts cleaned periodically. For added protection, consider adding air purifiers or UV lights to your system to capture pollutants and improve air quality.

Myth #6: “HVAC Systems Are Too Complicated for DIY Maintenance”

While it’s true that HVAC systems involve complex mechanics and electronics, many basic maintenance tasks can be easily handled by homeowners. Simple tasks like replacing air filters, checking for debris around outdoor units, and ensuring proper thermostat settings can be done yourself. Tackling these tasks can help you save money on professional maintenance and keep your system running smoothly between visits.

However, for more intricate issues like refrigerant levels or compressor problems, it’s best to call a professional.

What to do instead: Be proactive about small maintenance tasks to keep your system in great shape, but don’t hesitate to call a licensed HVAC technician for anything more complicated. Regular professional maintenance can help catch problems early and prevent costly repairs down the road.
