What is a service agreement? A service agreement is a maintenance program specifically designed to give you and your family peace of mind. Regularly scheduled maintenance of your heating and cooling system will prolong the life of your system in the long run. Our service agreement means that your system will be cleaned and inspected once in the heating and once in the cooling season. No matter the make or model of your equipment, Riesen PHI will alert you to any problems and correct them before you get caught without heat or air. OUR SERVICE AGREEMENT WILL LENGTHEN THE LIFE OF YOUR EQUIPMENT, NO MATTER THE MAKE OR MODEL. Regular filter changes are helpful, but may not prevent clogging.  Dirty fan blower wheels and clogged refrigerant coils are the #1 cause of costly repairs and premature compressor failure. SAVE HUNDREDS OF DOLLARS AND GET PEACE OF MIND. With regularly scheduled check-ups, your system will operate at it's peak, reducing your seasonal utility bills.  Peace of mind knowing that your furnace has had an up-to-date safety inspection.  WE ARE COMMITTED TO YOUR COMFORT! Should you ever have questions or problems with your heating or cooling system, a service agreement guarantees you'll receive prompt, professional, courteous, around the clock service from Riesen PHI.
