HVAC is short for Heating, Ventilation and Air Conditioning. HVAC is most often used to depict the whole heating and cooling system consisting of the duct work, air filters, humidification controls, and registers.

No, HVAC air filters vary due to quality and size, and some have specs that others don't. In most cases we recommend installing the filter your HVAC manufacturer recommends pairing up with your installed system, though you might be tempted to try some other filter type for convenience or to remove additional debris from your residence.

Good air conditioners can last as long as 15 years if they’re properly maintained, but average air conditioners are expected to develop problems after seven to ten years if they’re neglected. If you want to get the most out of your new system, check your filters monthly and replace them as needed, keep your outdoor unit clean and free of debris, and shade the unit during the hottest parts of the day. By performing a little easy maintenance, you can greatly extend the life of your air conditioner and keep it working at its best.
