Problems in an HVAC system can arise from a multitude of sources. An article on the Energy Star website notes, however, that regular maintenance can help to avoid certain problems that may creep up and lead to expensive repairs or unexpected system failure.
In order to keep potentially catastrophic problems at bay, the Energy Start article suggests the following:
Change Out Used Filters Regularly
The air filters in your system need to be checked every month. As soon as the filter starts to look dirty, change it. The maximum amount of time a filter should be used in a system is three months, whether the system is used or not during that time. Dirty filters make it more difficult for air to move freely through the system. This causes fans to use more energy in order to maintain the required airflow. Overworked fans are also more prone to failure.
Have Your HVAC Equipment Tuned Up Yearly
Just as a car would after it has spent a considerable amount of time on the road, the different parts of your HVAC equipment suffer from normal wear and tear over time. A yearly tune-up of your heating equipment by a Rancho Cucamonga HVAC technician will allow early diagnosis of problems that may become more difficult and expensive later on.
Inspect and Seal Ductwork
Inspections of your heating and cooling system’s ductwork should be conducted on a regular basis. Simply using your HVAC system can cause damage to the ducts, as it has to cope with the internal stresses that are associated with changes in temperature and atmospheric pressure. Also, vermin may sometimes tunnel into the ductwork in order to gain access to the favorable environment inside it.
Obvious signs of ductwork aging include the corrosion of the duct materials, mastic tape, or caulk. Leaks and collapsed duct sections should, of course, also be of highest concern. Leaks often cause streaks of dust to emanate from the ducting joints as air escapes under pressure from the system.
If any of these signs are observed, this is as good a reason as any to call in professional Rancho Cucamonga air conditioning repair technicians, like Day Aire HVAC, to test the system. After a thorough assessment, they should be able to pinpoint the source of the problem and take steps to remedy it.
