Operation of Heat Recovery Ventilators

The best contractors educate you on your home comfort system and Northern Air is here to help. Here are a few tips for maintaining and operating your hrv.

 Keep intake and exhaust outlets free from debris. Clean any build up of pollen or spider webs from terminations.

 Thoroughly clean inside of HRV annually. You will probably see dirt/ bugs/spider webs inside unit, which is normal.

 Remove the core and clean out all four sides with warm water and liquid soap detergent (this should be done in the summer). If unit is an ERV, vacuum core only.

 Remove the two sponge filters and clean under warm water and squeeze dry (every three months).

 Adjustments to the control should be made frequently as the weather changes from cold to warm. You require more fresh air as it gets colder and less when it gets warmer.

 Winter settings should try to maintain 35 to 40% humidity. This means it will be common to see minimum 3/8” of water collecting at the bottom of your window. Any more than that requires more fresh air to reduce humidity level.

 Summer settings should be in the “off” position.
