Stay Comfortable with Regular Maintenance

Take advantage of a Planned Service Agreement from Comfort Zone Service that includes seasonal checks of equipment and routine filter changes.  Meticulous troubleshooting addresses minor issues that quickly turn into major problems, even doubling operating costs.  Eighty percent of compressor failures that we are called to repair could have easily been prevented through seasonal inspection.  Something as common as dust or dirt collecting on the evaporator, condenser, and blower increases HVAC costs by fifty percent or more.  A mere one hundredth of an inch of dirt on an evaporator coil will diminish efficiency by up to five percent.  If these flaws are overlooked, more extensive damage is often caused, leading to far greater expense.

A Service Agreement from Comfort Zone Service pays for itself.  Depending on the condition of your HVAC equipment, we can save up to thirty percent a month on your utility bill, help you avoid costly repairs, and significantly extend the life of your equipment.  Your heating and cooling system is going to cost less to own, operate safely, and keep you more comfortable.  When you trust the maintenance of your essential heating and cooling systems to Comfort Zone Service, we take every extra step to ensure maximum rewards, and stand behind our work with a 100% Satisfaction Guarantee.  Comfort Zone Service is your trusted choice across Orland Park, IL, Tinley Park, IL, New Lenox, IL, Oak Lawn, IL, Homer Glen, IL, Mokena, IL, Orland Hills, IL.
