Myths are rampant about HVAC systems that result in inefficient energy use, increased costs, and even system damage. While these myths may be prevalent, with a little insight, homeowners can make better choices regarding their HVAC system for improved efficiency, savings, and comfort. Now, let’s explore some of the most common myths surrounding HVAC and debunk them.
Myth 1: Closing Vents Saves Energy
One of the most prevalent misconceptions is that closing vents in rooms that are not in use will save energy. The idea behind this myth is that by closing the vents, it supposedly forces the air to go into other rooms, perhaps saving energy by directing more air to where it’s needed. Unfortunately, this is not the case. Closing vents upsets the balance of airflow within your HVAC, forcing it to work harder to maintain the temperature. It might cause pressure to build up, resulting in inefficient system operation and increasing chances of breakdowns. To keep the operation at maximum efficiency, you should never really keep the vents closed but allow consistent airflow through your home.
Myth 2: Bigger HVAC Units Are Always Better
Another common myth that many homeowners believe is that the bigger the HVAC unit, the better it works. Although it would seem logical that a larger unit can deal with handling more air to cool or heat the house faster, this isn’t exactly true. On the contrary, over-sized HVAC systems will spell a couple of problems. AC Repair Greeley CO says, a larger system will often just short cycle on and off, which can lead to serious uneven temperatures and higher humidity levels in your home. It can also reduce the life span of the system because of the constant strain put on it. The secret to an effective HVAC system is selecting the appropriate size for your house, mainly by considering your square footage, insulation, and configuration. An HVAC professional will be able to help you determine the right size for your needs.
Myth 3: HVAC Systems Don’t Need Maintenance if They’re Working
Many homeowners are under the false impression that their HVAC systems don’t need regular maintenance as long as they’re working (source). However, HVAC systems are complex and require consistent upkeep to ensure they continue to run efficiently. Neglecting maintenance can lead to poor performance, higher energy consumption, and even early failure. Tasks such as changing air filters, cleaning ducts, and scheduling annual checkups with an HVAC technician can help extend the life of your system and improve air quality in your home. Routine maintenance also ensures that small issues are caught early before they become costly repairs.
Myth 4: Turning the Thermostat Way Up Heats the House Faster
It’s a common misconception that turning the thermostat way up will heat the house faster. This is actually a myth. Your HVAC system will heat your home at the same rate whether the thermostat is set to 70°F or to 80°F. After all, the higher the setting on the thermostat, the harder the system has to work to cool your house. That’s just using unnecessary energy when it’s much easier to set your thermostat at a comfortable temperature and let the system run easily.
Myth 5: New HVAC Systems Don’t Need to Be Tuned Up
Some homeowners believe that their new HVAC system doesn’t need maintenance because it’s “brand new.” While it’s true that modern HVAC units are designed to be more energy-efficient, they still require regular service to keep working their best. Newer systems have more advanced features, but failing to have annual inspections and replacing air filters or cleaning the ducts can lead to the system underperforming or breaking down, says EPA. The longer you wait for maintenance, the likelier you are to have expensive repairs. Routine maintenance also helps to keep your system’s warranty intact and can keep your system running at its best for many years.
Myth 6: It Saves Money to Turn Off Your HVAC System
Some people think turning off their HVAC system when they’re either away from home or at night saves energy and money. While turning off your HVAC system can save some energy, it may not be as effective as adjusting the thermostat to a more efficient setting. For instance, turning the system off completely during the summer can cause your home to heat up quickly, forcing the system to work harder when you turn it back on. Instead, consider setting the thermostat to a higher temperature in summer or lower in winter when you’re away or sleeping. This method uses less energy while keeping the house comfortable for when you return.
Conclusion
Understanding the realities of these HVAC myths empowers you to make more informed decisions about how you maintain and operate your system. Whether it is not over-sizing the HVAC unit or regular maintenance, small changes indeed lead to big savings in the long run. By debunking these misconceptions and using the HVAC system correctly, you can give a longer life to your system as well as save money on energy bills. Always consult with a professional HVAC technician if you’re unsure about any aspect of your system to ensure you’re getting the best performance and efficiency possible.
