Breathe Easy with Regular Maintenance

Maintaining Optimal Air Quality

Your furnace and air conditioner keep your indoor air comfortable, but adding a humidifier, air ventilator or air filter can drastically improve the quality of your air. Follow the advice below for keeping your healthy home systems running smoothly.

Air Quality Maintenance


The following information is for educational purposes only. Tampering with your system may void your warranty. If you have any questions about your system, call a Trane Comfort Specialist™.

Humidifier Maintenance

Trane humidifiers are mounted on an existing furnace system and are fed by a water line. These units add moisture to air that passes through the furnace, which can help alleviate the dryness that often comes during winter months. Here are a few humidifier maintenance tips that can be performed by you or your local Trane specialist to keep your unit running:

  • Periodically clean the distribution manifold, which is located at the top of the humidifier.
  • Clean the evaporator pad with a 1:3 water-to-vinegar solution. The evaporator pad should be replaced at least once per year.
  • Your operator's manual should provide maintenance instructions for the humidistat and solenoid, and tips for how to determine that they are working properly.

    Air ventilator maintenance

    As with most HVAC systems, air ventilator maintenance primarily requires regular cleaning or replacing of air filters once every three to nine months. Air filter cleaning can be done with a vacuum, or by rinsing the filter and letting it air dry. In addition to air filter replacement, periodically check to make sure the air ventilator’s intake and exhaust are unobstructed, and that the fan blades are relatively free of accumulated dust and dirt.

    Air filter maintenance

    Maintaining your air filter is easy and routine maintenance will keep you breathing easier. Most filters are easy to slide or swap out, and it's one of the few things you can do to maintain your filter without the help of a Trane Comfort Specialist. However, it's important to check your user manual before performing any maintenance on your Trane or any air filter.

    You should always double-check your user manual for specific recommendations, but generally speaking it's best to clean or change your filters once every 3 to 9 months. Remember, regular cleaning/changing of your filter will ensure the best filtration, increase the life of your machine, and give you peace of mind that you're breathing easier.


    To clean your CleanEffects™, simply remove your filter and then rinse or vacuum it. If you rinse the collection cells, allow them to dry thoroughly before replacing them.
