Gree HVAC. Humidifier Maintenance.

Your humidifier is designed to keep the ideal amount of humidity in the air. You don’t need to sweat annual maintenance for your humidifier too much. Just be sure to change the water panel before the heating season.

 

If you have a water-saver humidifier, you’ll need two water panels per heating season: One at the beginning and one about half-way through. How do you know if you have a water-saver humidifier? Your model number will include the letters WBP.

Geothermal systems are known for their reliability and durability. Keep yours operating at its peak efficiency by having your  geothermal expert check the unit once or twice a year. During the inspection, the technician will:

 

Replace the air filter as needed. Make sure the indoor coil, blower and drain pan are clean. Check the loop pressure and water flow. Ensure that all the components are functioning properly. If your geothermal unit is connected to well water instead of a closed loop, we recommend you have the heat exchanger inside the unit cleaned periodically. This will prevent the buildup of minerals that can reduce the performance of your system. Simple preventative measures like these will go a long way to helping your geothermal unit deliver the comfort, efficiency and reliability you invested in.

Lubricating the bearings is not recommended. The motors are factory lubricated.

Core maintenance: First, it’s very important to know which type of unit you have, because core cleaning varies by type and you could cause damage with improper cleaning. The serial number will include either the letters ERV or HRV to tell you what you have. For Energy Recovery Ventilator (ERV) cores, vacuum every 3 months to remove dust that would inhibit the energy transfer. Do not use water. The core should only be serviced when the outdoor temperature is between 60°F (16°C) and 75°F (24°C) and dry. 

 

NOTE: If the edges of the core are soft, do not try to service the core. The air passages can be damaged and/or closed off by handling it or trying to remove it. For Heat Recovery Ventilator (HRV) cores, wash once a year. And handle with care. First, soak the core for 3 hours in a bath of warm water and mild soap.

 

Then rinse under warm, not hot, water. Hot water and strong detergents can damage a heat recovery core. A dirty air filter will cause excessive strain on the blower motor. The filters in your ventilator are washable and should be cleaned every 3 months. Use a vacuum cleaner to remove the heaviest portion of accumulated dust, then wash in warm water. NOTE: Do NOT clean these filters in a dishwasher or dry them with heating appliances. This will cause permanent damage. Use lukewarm water to clean filters. Replace filters only when they are completely dry. Regularly check the screen on the exterior intake hood and clean as necessary.
