Common HVAC Myths Debunked
HVAC systems play a vital role in maintaining the comfort of your residential and commercial space. However, there are several misconceptions about their operation and maintenance. Debunking these myths will help reduce inefficiencies, unnecessary expenses, and potential system damage.
Here’s a look at some of the common misconceptions about HVAC to help you make an informed decision.
Bigger Systems Are Better
Many believe that a larger HVAC system will heat or cool their home more effectively. In reality, an oversized system can lead to short cycling, where the system frequently turns on and off without completing a full cycle. This reduces efficiency while increasing wear and tear on the equipment. Proper sizing based on your home’s square footage and insulation is crucial for optimal performance.
Closing Vents in Unused Rooms Saves Energy
While this may sound logical, it can actually make your HVAC system work harder. When you close vents, the air pressure in your ductwork increases. This forces your system to push air through a smaller space, leading to increased energy consumption and potential damage to your unit. Instead of closing vents, consider zoning your system for more efficient temperature control.
You Only Need Maintenance When Something Goes Wrong
Some homeowners think HVAC systems only need attention when there’s a problem. However, regular maintenance is essential for preventing breakdowns and extending the lifespan of your system. Annual tune-ups for both your heating and cooling systems ensure that everything runs smoothly and efficiently, saving you money in the long run.
Air Filters Only Need to Be Changed Once a Year
Your HVAC system’s air filter plays a crucial role in maintaining good indoor air quality and efficient operation. Depending on your home environment, filters should be replaced every 1–3 months. Homes with pets or allergies may need more frequent changes to avoid restricted airflow and strain on the system.
Thermostat Placement Doesn’t Matter
The location of your thermostat significantly impacts your HVAC system’s performance. Placing it near windows, doors, or in direct sunlight can lead to inaccurate temperature readings, causing your system to overwork or underperform. Installing the thermostat on an interior wall away from drafts and heat sources ensures more accurate readings and efficient operation.
Duct Tape Is Suitable for Sealing Ducts
Despite its name, standard duct tape is not ideal for sealing HVAC ducts. Over time, the adhesive can deteriorate, especially under temperature fluctuations, leading to air leaks. Instead, professionals recommend using mastic sealant or metal-backed (foil) tape designed specifically for ductwork to ensure long-lasting seals.
High-Efficiency Systems Automatically Reduce Energy Bills
While high-efficiency HVAC systems are designed to consume less energy, simply installing one doesn’t guarantee lower bills. Factors such as proper installation, correct sizing, regular maintenance, and your home’s insulation all play pivotal roles in actual energy savings. Without addressing these elements, the anticipated reductions in energy costs may not materialize.
Running Your HVAC System Less Frequently Saves Money
Some homeowners believe that using their HVAC system sparingly will lead to significant savings. However, frequently turning the system on and off can cause more harm than good. HVAC systems operate most efficiently when maintaining a consistent temperature. Constantly adjusting the thermostat or turning the system off and on forces it to work harder, potentially increasing energy consumption and wear.
