Preventative Maintenance

How can you lower your utility costs? 

51% of your utility costs is from you heating and air conditioning equipment. Regular maintenance on your HVAC system will increase your system efficiency, reducing your monthly energy cost. 

What will a heating and air conditioning technician preform during a maintenance visit?
