Dirty Air Filters
Furnace filters play an important role in filtering the air circulated by the AC system. When they collect too much dust and other particles, the system’s efficiency is reduced and more contaminants get into the indoor air. Most disposable air filters require replacement every 90 days at least. Permanent ones should be cleaned regularly in line with the manufacturer’s instructions.
When out there in the market buying replacement filters, consider checking the minimum efficiency reporting value rating. The higher the value, the more particles the filters will capture. Also, consider the product thickness. Very thick filters may cause the AC system to work harder. For most families, the disposable electrostatic filters are a good choice because they can capture most types of particles and microorganisms without affecting the system’s performance adversely.
Drain Line Clogging
Among other common cause of this kind of problem are algae and dirt. For in case the drain lines are clogged, the drain pan will overflow and this will lead to water damage. Solving this problem is simple; the common way is to use a wet vacuum for extracting the dirt and algae. You need to attach it to the exterior outlet, after removing the paper filter, of course. It is best to start off with gentler suction, just to be on the safe side. This job requires some skill, so you may consider turning to an AC repair specialist.
One method for preventing clogging is to pour a cup of white vinegar into the line system from the inside. It works effectively while being an extremely cheap solution. Generally, white vinegar cannot damage the pipes, regardless of their make. If you have concerns, however, you should check specifically for the material which yours are made from.
Dirty Condenser Coils
The condenser unit is installed outside so the coils can get dirty quite quickly. When this happens, exhaust air is not properly released and the AC system has to work harder and use more energy. Use the garden hose to remove the dirt. Make sure that the spray is not very powerful as it can bend the coils. For this reason, you should not use a pressure washer for this job. If there are any bent coils, you should straighten them after the cleaning. There are plastic combs which are specially designed for this job.
