Certain Air offers some really beneficial Honeywell products.  A digital thermostat will give a more accurate temperature reading resulting in a more efficient operating system.  If dust and allergens are of concern, you may be interested in the Honeywell Media Filter.  Or, if you suffer from mold related allergies, you may consider having a UV treatment system installed.  Call for more details or click on the pictures below for more information on some of the products we offer.  Pictures may vary depending on particular job specifications and availability.
