When it comes to your HVAC system, there are plenty of misconceptions that can lead to inefficiency, costly repairs, or unnecessary discomfort. Today, we’re debunking some of the most common HVAC myths to help you make better decisions for your home’s heating and cooling.
- Bigger Is Always Better
Many people assume that installing a larger HVAC system will automatically improve their home’s comfort. However, a system that’s too big for your home can be inefficient, leading to higher energy costs and uneven temperatures. The key is choosing the right-sized unit based on your home’s square footage and other factors. Always consult with a professional to ensure your system is properly sized. - Closing Vents Saves Energy
While it may seem like closing vents in unused rooms will save energy, it can actually cause more harm than good. Closing vents disrupts the airflow and can lead to pressure imbalances in your system. This forces the HVAC unit to work harder, which can increase wear and tear, reduce efficiency, and raise your energy bills. - HVAC Systems Only Need Maintenance When They Break Down
Waiting until your HVAC system breaks down is a costly mistake. Regular maintenance, like changing filters and checking refrigerant levels, ensures that your system operates efficiently year-round. An ounce of prevention is worth a pound of cure—getting routine check-ups can prevent breakdowns and prolong the life of your system. - You Should Set Your Thermostat to the Same Temperature Year-Round
It’s common to keep your thermostat at the same temperature year-round, but your heating and cooling needs change with the seasons. In the winter, set your thermostat lower while you’re home and awake, and at a lower temperature while you’re sleeping or away. In summer, try setting your thermostat a few degrees higher to save on cooling costs. A programmable or smart thermostat can help you automate temperature adjustments. - Air Filters Don’t Need to Be Changed Often
Some people think they only need to replace their HVAC air filters once or twice a year, but this couldn’t be further from the truth. Depending on your system and filter type, air filters should be changed every 1-3 months to maintain airflow, improve air quality, and reduce strain on your system. A clogged filter can lead to poor performance and even cause your system to fail. - Your HVAC System Doesn’t Need to Be Cleaned
Dust, dirt, and debris can build up in your HVAC system over time, leading to decreased efficiency and poor air quality. Regular cleaning of your system, including ducts, coils, and blower components, can keep it running at optimal levels. Don’t wait until you notice a problem—schedule a professional cleaning as part of your routine maintenance.
By busting these myths, you can keep your HVAC system running smoothly, save money, and ensure a more comfortable home. Have questions about your HVAC system? Contact CMC for expert advice or schedule a maintenance check today!
