Preventative Maintenance

When most people think about preventative maintenance, they think of oil changes and brake pads and other basic steps required to ensure that a car is drivable for as long as possible. When it comes to HVAC, routine maintenance is far more simple and much more important. The reason is this: If you don’t maintain your heating and air conditioning system, its life is shortened, it’s less effective, costs more to operate, and poses safety risks. Poorly maintained equipment is far less efficient, costing hundreds of dollars more each year in operating costs. That’s why our Comfort Club members are always smiling; they have cheaper utility bills, they are more comfortable, and they rest easy knowing that they’re safe from the hazards of poorly maintained HVAC equipment.

Call us anytime at (847) 261-5000 to ask about how preventative maintenance can help you.
