When it comes to keeping your home comfortable, your heating and cooling system plays one of the most important roles. Unfortunately, there are many misconceptions about how HVAC systems actually work. At Three Rivers Heating & Air, we’ve spent over 40 years helping Sacramento families with their comfort needs, and along the way, we’ve heard just about every myth in the book. Today, we’re setting the record straight.
Myth 1: Turning the Thermostat Way Down Cools Your Home Faster
One of the most common myths is that if you set your thermostat lower, your AC will cool the home more quickly. The truth is, your system works at a consistent pace until it reaches the set temperature. All you’re really doing is forcing it to run longer, which wastes energy and raises your utility bills.
Myth 2: HVAC Maintenance Isn’t Necessary Until Something Breaks
Many homeowners believe that HVAC maintenance is optional unless the system stops working. In reality, regular maintenance is the key to efficiency and longevity. By scheduling routine tune-ups with Three Rivers Heating & Air, you can prevent costly repairs and ensure your system performs at its best year-round.
Myth 3: Closing Vents in Unused Rooms Saves Energy
It might seem logical that closing vents in unused rooms would help you save energy. However, modern HVAC systems are designed to balance airflow throughout the home. Closing vents can actually increase pressure in the ducts, leading to leaks or even damage to the system.
Myth 4: Bigger Systems Always Work Better
When it comes to HVAC systems, bigger is not always better. An oversized unit will cycle on and off more frequently, leading to uneven temperatures, higher energy use, and unnecessary wear and tear. The right size system is crucial for efficiency and comfort. Our experts at Three Rivers Heating & Air specialize in helping Sacramento homeowners choose systems tailored to their specific needs.
Myth 5: Air Filters Only Need to Be Changed Once a Year
Many people underestimate how often air filters should be changed. Depending on your home’s environment—pets, dust, or Sacramento’s air quality—you may need to change your filter every 1–3 months. A clean filter not only improves air quality but also helps your system run smoothly.
