Your HVAC system is one of the most significant investments in your home. With such an investment comes the responsibility to ensure it runs efficiently and lasts as long as possible. Regular maintenance and timely repairs are key to keeping your system working at its best. Preventative HVAC services also help avoid costly breakdowns. However, there are many misconceptions about HVAC services that can mislead homeowners. Let’s clear up five of the most common myths about HVAC maintenance and care.
Myth 1: You Only Need to Change the Air Filter Once a Year
Some people believe that changing the air filter once a year is sufficient, but this is far from true. Air filters trap dust, dirt, and debris, which can clog the system if not replaced regularly. This leads to restricted airflow and decreased efficiency. In general, air filters should be changed every 3 to 6 months. However, if you have pets, burn candles, or suffer from allergies or asthma, you may need to change the filter more often. Upgrading to a higher-efficiency filter may also be beneficial for improved air quality.
Myth 2: Routine Maintenance Isn’t Necessary
Many homeowners skip routine HVAC maintenance, thinking it’s unnecessary. However, just like your car needs regular oil changes, your HVAC system needs periodic tune-ups to ensure it runs efficiently. Scheduling maintenance at least twice a year, typically before the heating and cooling seasons, can help prevent wear and tear, improve system performance, and extend the lifespan of your equipment. Regular check-ups can also help identify minor issues before they become major (and expensive) repairs.
Myth 3: Bigger HVAC Units Are Always Better
The idea that a larger HVAC unit is more effective is a common misconception. While it might seem like a bigger unit would cool or heat your home faster, oversized systems often run for shorter cycles. This doesn’t allow enough time for proper dehumidification, leaving your home feeling less comfortable. Additionally, short cycling can increase energy costs and wear out your system faster. It’s important to have an HVAC professional assess your home to recommend the correctly sized unit for optimal efficiency and comfort.
Myth 4: Lowering the Thermostat to the Lowest Setting Will Cool Your Home Faster
Many people believe that setting the thermostat to a very low temperature will cool the house more quickly, but that’s not how HVAC systems work. Air conditioners operate at a consistent rate, regardless of the temperature setting. Setting the thermostat extremely low won’t make your home cool faster; it will just cause the system to run longer than necessary, wasting energy. Air conditioners are designed to cool your home to about 20°F lower than the outdoor temperature. If it’s 95°F outside, your system will likely only cool your home to around 75°F.
Myth 5: The Thermostat Location Doesn’t Matter
The placement of your thermostat is crucial to how effectively your HVAC system maintains the desired temperature. If the thermostat is placed near a heat source, such as direct sunlight or kitchen appliances, it can cause false readings. This may lead to your system running more frequently than needed. Ideally, the thermostat should be installed in a central location away from direct sunlight, air vents, or appliances that could affect its readings.
