Most electrical devices consume an exorbitant amount of Current when they start up. When it comes to air-conditioners, they use almost 5 to 10 times more power while starting as compared to the current used when running. The problem is this current surge generates a large quantity of heat too, which can damage several vital components such as the terminals, run Capacitor, windings, and compressor.
How to ensure safety of internal parts?
A hard start capacitor can provide the necessary protection by lowering the amount of time the compressor needs to start, thereby reducing the overall stress and strain on the machine. Earlier this capacitor would only be placed in faulty machines in Portland during air-conditioning repair (after their performance dwindled), but now they are being inserted from the beginning itself. It becomes all the more essential if the unit is under direct sunlight because the parts of the machine are receiving heat from the sun in addition to the amount produced by the current during start-up.
Why do you need hard start capacitors?
Did you know that several decades back all single-phase air-conditioners, heat pump, and refrigeration compressors were equipped with hard start units at the time of manufacturing from the factory itself? However, it was discontinued because the overall cost of the electrical devices increased greatly. But these capacitors can now be installed separately in order to keep the air-conditioner functioning effectively without having to pay a fortune. It comprises a mechanical potential relay and a start capacitor that can be wired to the compressor to help during start-up with the most efficiency, by going up to normal rated speed almost ten times quicker than those without hard start equipment. In normal situations a compressor has to put in more effort and the efficiency is wasted, but a hard start device improves the efficiency to more than 98%.
What are the advantages of hard start devices?
Installing a hard start capacitor has the following benefits:
It extends the longevity of the compressors (almost 5 years) by taking them up to full speed faster and more efficiently.Helps compressors to start under harmful circumstances too, such as high head pressures, low voltage, or undersized wiring.Bypasses contactor – less “light flicker” during start-up.Significant reduction in electric bills every month.
The installation process is extremely easy – you just need to connect the plugs of the capacitor to the HREM and C ports of the compressor inside the machine. Although it can be a DIY task, it is advisable to get it done by professionals specializing in HVAC maintenance in Portland.
