If you're looking to upgrade your air conditioning system, you'll need to consider the type of fan motor you'll be using. Depending on the type of air conditioner you have, you may need a single-speed, two-speed, or variable-speed fan motor. Single-speed motors are the most energy efficient and operate at one speed. Two-speed and variable-speed motors are best for two-stage air conditioners. The fan motor is an important part of the heating, ventilation and air conditioning (HVAC) system.
It is responsible for circulating air throughout the house and can help improve air circulation and reduce energy costs. The fan motor is usually located in the air controller, and when working on these motors, it is important to follow safety precautions such as discharging capacitors and interrupting power supply to the unit. The cost of replacing a fan motor will depend on the type of fan motor (single-stage, two-stage, or variable-speed) and size of the fan motor. An experienced DIYer can certainly replace a fan motor, but they may have difficulty determining if the problem is with the fan motor or one of the many cheaper parts that keep it running. If your HVAC system is still covered by the warranty, or if the fan motor has already been replaced once and is still under warranty, you will usually only have to pay for labor to change the unit and not for the unit or part itself. The same type of fan motor is used in both home air conditioners and ovens.
The fan motor moves hot or cold air produced by the oven around the house so that temperature is maintained at settings preset by thermostat. Cars also have ventilation motors, which are part of the system responsible for distributing warm air throughout the car when the heating system is turned on. HVAC fan motors usually last 10 to 20 years, but they can break down sooner or later depending on how often air treatment system works. Upgrading your fan motor can help improve air circulation and reduce energy costs. When you change your home air conditioner or oven fan motor, you're actually replacing both at once, so price is same regardless of whether HVAC professional calls it an “AC fan motor” or “oven fan motor”.
