Idaho Heating and Cooling can create an oasis of clean air during allergy season with York Affinity Air Cleaners, Humidifiers, Dehumidifiers, and York Ventilator Systems. Portable systems only provide partial in-home filtration and their efficiency is compromised at best. Indoor air can be between 5 to 100 times more polluted than outdoor air and with IHC and York, you never have to worry about poor air quality again.
