How to Care for Your HVAC Condensor Fan Motor

The condenser is located in the outdoor unit of the HVAC system, along with the compressor and condenser coils. This HVAC condenser fan motor is key to the proper operation of the entire HVAC system, keeping the air conditioner cool as the fan motor turns the blades, blowing air across the condenser coil where the refrigerant is cooled from hot gas into a liquid. During this process, warm air from the house is exhausted outdoors.

It's important to keep the condenser from overheating or working too hard. Regular maintenance includes lubricating the fan and other parts at least once a year, before you turn the air conditioner on for the season.

Condenser Problems

Some of the main things that can go wrong with the condenser are these:

  • Motor can go bad. If the motor is incorrectly sized in the unit, it is likely to malfunction.

  • If the fan blades are not installed correctly, airflow may be impeded and the motor may overheat.

  • An incorrect start run capacitor or incorrectly sized fan blade may cause a condition called overamping.

  • Poor air flow can also result from obstructions near the unit, such as weeds, leaves, grass, shrubs and garden furniture. Clear all vegetation and debris away from the condenser so it can properly exhaust warm air.

  • Dirty coils can prevent the unit from transferring warm air, which will result in inadequate cooling in the home. The coils should be cleaned annually.

  • Refrigerant leaks can develop in the condenser and the lines leading to it. Insufficient refrigerant can result in inadequate cooling, as well as strain on the compressor, leading to breakdown.

To tell if your condenser fan motor is overheating, place your hand on the unit. You can also check the temperature of the condenser fan motor with a regular thermometer, but it's best to hire an HVAC professional with proper equipment to do the job.

Different HVAC Types and Their Benefits

HVAC Types_iStock-898894076.jpg

Driven to boost the efficiency levels in American homes and businesses, the HVAC industry over the last decade has revolutionized HVAC equipment so that it runs cleaner, more efficiently and delivers greater comfort than ever. If you're poised to replace your HVAC system and are planning to shop around among the various HVAC types, read this brief summary on the latest trends.

1. Forced Air/Central Air

The most common type of heating and cooling system, forced air/central air has come a long way. Air is heated or cooled and then delivered through a system of ducts, and distributed through various vents and registers. New technology has vastly improved this type of system, and includes condensing furnaces, modulating air handler fans, scrolling compressors, as well as smart thermostats so you can adjust the temperature when you're away.

2. Heat Pumps

Heat pumps are taking more market share in the cooling and heating industry, as their ability to heat in colder climates is improved. Heat pumps move warm air from the outdoors into the home to heat it, then move warm air from the home outside to cool it. Heat pumps are efficient and clean to run. They generally employ ductwork to distribute conditioned air. Some efficient features available for heat pumps are two- or variable-speed motors for air handlers; two-speed or scrolling compressors to regulate output and backup burners to boost the heat pump's ability to heat during cooler weather.

3. Ductless Mini Splits

As the name implies, ductless mini splits don't require ducts, bur distribute air through air handlers placed around the house. They are a kind of heat pump, so are efficient and clean to run. These are a good choice for a home that has never had ductwork installed.

4. Geothermal systems

Geothermal systems are heat pumps that move heat from the ground or water source into the home for heating and out of the home for cooling. The configuration of your property will be a factor in determining if you can accommodate a geothermal system.
