Why is my AC having a hard time keeping up?
You might be low on refrigerant or have a worn out motor or a dirty evaporator coil. Not all AC problems demonstrate themselves with loud sounds or funny odors coming from your system. Some of them simply reduce the AC’s ability to run, and all you notice is less cool air in the house.
What to do if your AC unit won’t start?
Turn off the A/C unit and call in an HVAC technician to replace the capacitor as soon as possible. This is a quick and simple repair for a professional. If you leave the unit running, the fan motor will keep attempting and failing to start. The capacitor may also be used to keep the fan motor running properly as well as starting it.
When to diagnose and repair an air conditioner?
If a compressor is frequently tripping the circuit breaker (or blowing the fuse) which protects its circuit, compressor and wiring diagnosis and repair are needed. Also check: the start relay and all electrical wiring connections to the compressor motor.
Do you need a hard start for an air conditioner?
A “hard start kit” is basically a capacitor which gives an extra electrical “jolt” to the compressor motor to get it moving. A starter relay may also need to be installed or replaced. Some air conditioning compressor brands do not usually need a hard start kit. GE, Trane, and Manurope are examples that do not usually take this kit.
What happens if you turn your air conditioner back on too soon?
If you turn the system back on too soon there is a risk of liquid slugging damage – liquid refrigerant enters the compressor and damages the piston, head, or most-likley bends a valve. That can destroy the compressor motor. So if the compressor is not starting in this condition we simply turn it off and wait.

What should I know before replacing my air conditioner?
Maybe you’re not sure what to do. Whatever the reason you’re considering a new air conditioner or furnace, you’ll want to go through this handy checklist to make sure you are shopping for the right equipment and asking contractors the right questions. 1. How much time do I really have to replace my system?
Is it better to replace the whole AC system?
However, with older systems, it’s generally a better idea to replace the entire system at once. The inside and outside portions of your AC system were designed to work together. In an older air conditioner, new condensers that are an exact match for the system are hard to come by.
Can a new air conditioner be installed with an old unit?
For example, if the air conditioner is relatively new and under warranty, your manufacturer may provide you with a new completely compatible unit at little or no cost. Because the unit is identical to the existing system, and because it is still designed to work with the inside portion that is already in place, it should work properly.
