Solution: Replace drier / (sand and spray paint - only a temporary solution).
Solution: Replace drier, pull a vacuum charge of the system. If an R-22 system consider replacement.
Effect: This could cause or be the cause of other electrical failures. Electrical failures usually cause another failure that will be linked to the first. Loose connections cause heat, which causes over amperage, which causes melted wires, which causes burnt contactor points, which causes bad capacitors, which causes burnt fuses. Welded contactors will make the system run continuously, never turning off, resulting in frozen coils.
Solution: Replace the contactor when recommended or possibly every 5 years, for maintenance. Add a hard start kit to the system to reduce high amperage upon start up or when appropriate. Add a time delay to prevent short cycling. Have capacitor checked for proper microfarads and all wiring for being loose or overheated.
Replace contactor 30 - 40-amp
Effect: Burned wiring could cause fire, burnt or welded contactors, weak or bad capacitors, electrical shorts, blown fuses, failure of unit. Miss wired could cause failure of unit, blown fuses or inoperable system.

Effect: Condensers that are in fair to poor condition will not remove the same heat load as a new one. Also, higher energy bills, more break downs and repairs will be inevitable.
 Solution: Consider replacement of system, when a system is in poor condition it would be beneficial to consider replacement, due to the amount money it cost for repairs and operation of existing systems.
Condenser in poor - fair condition
Effect: A shorted time delay will blow a low voltage fuse or burn a transformer. Also may not allow a system to come on. A system without a time delay is usually not protected from short cycling of system. A time delay will prevent a system from short cycling and protect against power surges.
Solution:Â Install a new time delay when there is none to prevent short cycling of the condenser or the one there is shorted or not working.
Replace or install time delay
Effect: During a power surge extreme high voltage will spike your electrical system therefore creating excessive voltage to the unit possibly shorting or grounding your compressor.
 Solution: Install a surge protector to protect from high voltage surges or power outages.
Effect: Possible kinking of the lines or restrictions occurring. Aesthetics are poor.
 Solution: secure lines possibly run new line set if needed.
Effect: The system will not cool properly or remove the heat from the house, the compressor may run hot and damage the compressor.
Solution: Run the correct copper lines for the system that is installed, also check ductwork and return for correct size.
 Solution: Repair or replace copper lines immediately.
Effect: The rubba tex helps keep the suction line cool which helps cool the compressor. This results in higher temperatures and efficiency loss.
Solution: Replace the rubba tex and check pressure and temperatures to make sure system is working to proper efficiency.

Effect: Excessively expensive refrigerant, phasing out of production as of 2020, the cost of the refrigerant will be cost prohibitive to purchase.
Solution: Â There is only one solution and that is to replace the system with a 410-A unit. If your system needs refrigerant, we strongly consider replacement of the system.
R-22 systems will be cost prohibitive in near future
Effect: Â Dirty coils are one of the worst problems to have. This causes, low efficiency, low air flow, low cooling capacity, sweating vents, compressor sweating, damage to compressor, coil will freeze up, and water will leak from the coil once defrosted. This is the single worst problem for an a/c system. It must be cleaned or replaced.
Solution: A coil can be pulled and cleaned but this could be very expensive based on the installation of the coil. Also, keep in mind, there is no way of knowing if the compressor has been damaged due to the dirty coil. If the coil is dirty the blower will also need to be pulled and cleaned as well. Consider the cost of repairs to replacement.
Dirty evaporator coil, must be cleaned or replaced
Effect: low capacity, high humidity, high energy bills, overheated compressor, coil freezing up, excessive repair cost until leak is repaired or part is replaced. The costliest problem for a system.
Solution: Â A leak check can be performed several ways some more costly than others. Electronic leak check is the most cost effective. Isolate and pressure test system with dry nitrogen, proves it is leaking.
