Your energy bills can decrease as much as %70 by just having the system maintained.If your current Heating and Air Conditioning system has not been maintained at least once a year for conservative users, and possibly twice a year for more frequent users ( residential), commercial maintenance should be done quarterly, and for all users the filter should be changed 3-4 times per year. The possibility that your system is running inefficiently and causing wear and tear is high. There are many problems that can arise by not maintaining your HVAC system. To Start : by simply not changing the filter when needed (3-4 times annually) or not even having a filter installed at all, a chain reaction of events will take place and the system will eventually break down. The most common problem related to not regularly changing your filter is the evaporator coil will clog up with dirt, grime, soil, pet dander, etc. and will restrict air as much as 90%, in turn causing many components to overwork and overheat then will break down, energy bills will increase as much as 75%, along with many other problems. With a dirty/clogged coil, the air you breathe is polluted and can have health effects, especially in people with allergies and health problems. Cleaning the outdoor condenser coil and keeping it free from suffocating is vital, as well as many more variables to consider within the whole system.
