Between changing your filter and scheduling regular maintenance and ensuring that you heat or cool your home effectively, there's an abundance of information available regarding how to keep your HVAC system in good working order. With so many different views and information sources, it's difficult to discern facts from fiction. Don't be concerned. We're going to dispel some of the more popular HVAC and air conditioning myths to ensure your family is comfortable and that your HVAC system is in good condition.

Myth 1: Turning off your AC after you leave your home is an energy waste.

Busted! It's a common belief that setting your air conditioner to a higher temperature during your day can be more effective than shutting it down completely. In fact, it conserves energy by shutting the unit off when not in use.

TIP! New thermostats with programmable settings conserve the energy of your home by turning the AC off after you leave and turning it back on when you return.

MYTH 2: You just need to replace the filter once per year.

Busted! The filter clogs up the system and decreases airflow. Clean or replace your filter each month as the system is running.

MYTH 3: The larger the HVAC system, the more efficient.

Busted! Find a system that's too big, and it'll continue to cycle between on and off, which costs you more to run and reduces the life of the device.

MYTH 4: Shut off the vents in rooms that are not being used to improve efficiency in energy use.

Busted! Vents that are closed can increase the air pressure inside the ducts and cause leaks along the vent seams.

MYTH 5: The location of my thermostat does not affect my heating or cooling.

Busted! Don't place it in close proximity to radiators, vents, and windows. It might cause the system to shut down prematurely or continue to run for a long period of time.

Myth 6: I do not need to do regular maintenance.

Busted! Just like your automobile, your HVAC is a sophisticated mechanical system that requires regular tune-ups. A thorough inspection can protect you from serious issues later on.

Myth 7: An energy-efficient device will automatically reduce my electric bill.

Busted! It's a great beginning, but if you have windows that leak and have poor insulation, your HVAC equipment won't prove to be efficient.

MYTH 8: The outdoor unit should be covered in the winter months.

Busted! If your HVAC system is a heat pump, be sure to cover it because it operates all year. In the event that the snow is heavy, put a sheet of plywood over the fan. The cover seals the fan from moisture and accelerates the process of corroding.
