Myth 1: Bigger HVAC Units Are Better

Contrary to popular belief, a bigger HVAC unit won’t necessarily make your home more comfortable. In fact, an oversized unit can lead to frequent on-off cycling, causing wear and tear and inefficiency. The key is to install a unit that’s just the right size for your home. Find more about our optimal HVAC services and how we can help you choose the right one.

Myth 2: You Only Need to Change Your Filter Once a Year

This is one of the most commonly heard myths. In reality, the frequency of changing your filter depends on the type of filter you use, the air quality in your area, and if you have pets. Generally, it’s advisable to check your filter every 2-3 months.

Myth 3: Turning Your Thermostat Down Will Cool Your House Faster

Truth is, no matter how much you lower the thermostat, your AC or heater will cool or heat your home at the same rate. Moreover, drastically reducing the temperature could cause your unit to work overtime thus increasing your energy bills.
