An air conditioner is one of the essential appliances at home. It helps keep the house cool and comfortable on hot and humid days, as well as improve air quality in the house. Just like any other mechanical appliance, air conditioners start losing their efficiency over time. If you find yourself setting it to a higher setting, or notice poor air flow from the AC, the system may be calling out for repairs or servicing. Nothing necessarily has to be broken for the air conditioner to lose its efficiency. Some of the common causes of poor air flow from the AC are discussed below.
1. A Clogged Air Filter
The air filter will at times get clogged making it hard for air to pass through. The filter traps lint, dust, and other debris to help ensure air pumped inside is free of these among other allergens. The air filter will in most instances get clogged a month or two of using the AC system actively. This can be in summer when it is hot outside and with dust everywhere. While you could opt to get, the filters cleaned, changing these regularly can help restore good air quality and improved airflow in the house. You should also consider having the AC system serviced after at least three months to check for other issues that could be causing low air flow.
2. Trouble With The Blower Fans
The blower fans push air through the air vents onto the evaporator coils into the ductwork hence making cooling possible. Malfunctioning blower fan may however have a significant impact on airflow, hence call for repairs or replacement immediately. The most common issues with blower fans is a loss of power, or even worse, a broken blade. A broken blade will however cause the AC system to produce rattling noises which should be investigated immediately. Other issues such as a dead capacitor, burnt-out motor, or broken belt can be repaired restoring the fan to its former glory.
3. Leaky Ductwork
If the AC unit, however, functions appropriately, but you still have weak air flow, then the problem may be with the ductwork. Leaky ductwork causes the flow of air to reduce significantly thus having a very little impact to room temperature and air supply. A broken duct, corrosion, poor installation, constructional damage, etc. are some of the common causes of reduced hair pressure in the ducts. Having a specialist look into these can help troubleshoot the problem, and even seal or repair the vents. If the vents are however damaged beyond repair, he/she may have to replace them altogether.
These are just but a few common causes of poor air flow from the air conditioner. While some of these issues may be inevitable, having the system serviced regularly and maintained properly can give the system a longer life with improved efficiency. You also need to hire a specialist in the same to help with the installations as well. Most suppliers will offer the service for a fee as well. Just be sure to hire a licensed and certified technician to do the installations, and servicing too.
