Maintenance of your HVAC equipment is very important. It has been stated by Energy Star that the most common causes of failure for HVAC systems are neglect and dirt. Think about it like this, those units are operating around the clock all year round. That is like putting 100,000 miles on a car. You give your car an oil change more than once a year, right? So why wouldn’t you maintain your furnace and air conditioner? Scheduled maintenance on your equipment can prevent frequent and costly repairs.
