Will a To-5 kickstart cap for 1 to 3 ton units possibly be able to help a 4 ton unit compressor start at all? Ri
You need to call an HVAC company to have that A/C unit serviced. It sounds as if the compressor may need attention, the existing capacitors are in need of replacing, or the unit has been grossly overcharged. Any of the above could cause the condition that you mention. Do not add any &quot;starting kit&quot; until the unit has been serviced by a competent service company. If there is a problem with the unit you cannot fix it by adding a kickstart capacitor.
