What is involved in a whole-home humidifier installation and maintenance? Installing a humidifier is usually an easy job when you upgrade your furnace. But you can also have a humidifier fitted to your existing heating and cooling system. Periodic cleaning and draining of the reservoir is strongly recommended to maintain the system. Service Experts Heating & Air Conditioning can provide maintenance on the humidifier as needed, or proactively as part of our PLUS Maintenance Agreement.
