It’s hot here in Mesa, with average daily temperatures landing somewhere between 104-105 degrees. Clearly, this is not the best time of year for your air conditioner to breakdown, but it does happen. A common area in which breakdowns occur is the indoor unit, also known as the blower or air handler. This unit houses a fan and the evaporator coils, and is responsible for blowing the cool air into your home. Different problems can affect the components in the blower as we’ll outline below, but all can lead to air conditioning repairs in your home.
The fan in your blower can experience a few different problems:
- Motor issues – motor can overheat or burnout
- Electrical/wiring issues – wires and connections can corrode and fray, which may impair connections and delivery of electricity
- Problems with loose or bent fan blades – fan blades can bend, loosen or break, which may interfere with other parts of your system
Any of the above problems can cause your blower’s fan to either slow down or stop turning completely. The result is low/no airflow in your system, which can cause warm air to blow through your air conditioner vents, or none at all.
Air flow, as mentioned above, is very important in the operation of your air conditioning system. One of the biggest culprits of air flow obstruction is a dirty air filter. The air filter constantly collects the dirt and dust in your system, so it can become dirty rather quickly. Once the filter is fully suffused with both kinds of particles, it can no longer filter and can obstruct the air going into your system. Low air flow can lead to warm air, icing and other problems.
The evaporator coils can gather dust and dirt, and if not cleaned at least once a year, these particles can form a layer that acts as insulation on the coils, inhibiting the heat release and cooling cycle. This can result in warm air and/or ice formation on the coils.
