Some other things you can do to make life easier on your system include:
Change or clean the filter.
Most disposable filters should be replaced every thirty (30) days. As dust and other particles collect on the face of the filter, the air flow to the Evaporator Coil slows down. This forces the Air Handler to work harder and longer to circulate (and cool) the air in your home and will shorten the life of the fan and fan motor. Also, as the air flow slows, the risk of ice forming on the Evaporator Coil increases. If enough ice forms on the Evaporator Coil, your system will freeze and shut down. Freezing the Evaporator Coil will also shorten the life of the coil, which can be an expensive repair.
Set your thermostat to a reasonable temperature during the hottest part of the day.
If the outside temperature is 95 degrees, your system will strain to maintain a temperature of 70 degrees inside your home. Since most families are not in the home during the week due to work and school, set your thermostat to 76-78 degrees. Then, you can set it back down to a cooler temperature in the evening when everyone is home. This has the added benefit of lower evening temperatures, which is easier on your system. Ask us about programmable thermostats and remote thermostats. These thermostats enable you set your thermostat to the most energy-efficient temperatures throughout the day.
Installing ceiling fans can go a long way toward circulating cool air in a given room. When installed properly, fans can work in concert with your system. Every little bit helps.
Draw blinds or drapes to block sunlight during the hottest part of the day.
Ensure that your home is properly insulated and that windows and doors are properly sealed so as not to allow hear in…or cool air out.
Outdoor Condensing Section.
Keep your outside Condensing Section free of dirt, leaves and anything else that might restrict airflow. Again, the slower or more restricted the air flow, the harder your system will have to work. This will lead to shortened life on system components.
