Frequently Asked Questions

Why is "coil cleaning" more than just spraying the unit with a hose?

A professional cleaning involves both the indoor evaporator coil and the outdoor condenser coil. While a homeowner might rinse the outside unit, a technician often uses specialized alkaline or acidic foaming cleaners to break down the “biofilm” and microscopic oxidation that a hose cannot reach. If these coils are even slightly dirty, they act as an insulator, forcing the compressor to work up to 30% harder to reject heat. This extra strain is the leading cause of “burnt-out” compressors during the first major heatwave of the year.

What is "amperage draw," and why does a technician measure it?

During a maintenance visit, a technician uses a clamp meter to measure the amperage draw of your compressor and fan motors. Every motor has a “Rated Load Amps” (RLA) limit; if a motor is drawing more power than it’s rated for, it indicates high friction (lack of lubrication) or a failing internal winding. By catching a “high-amp” draw early, a technician can often save the motor by replacing a 50 capacitor or lubricating a bearing, preventing a 2,000 motor replacement later in the season.

Does the refrigerant level need to be "topped off" every year?

No. An air conditioning system is a hermetically sealed loop; it does not “consume” refrigerant like a car consumes gas. If your system is low on refrigerant, it means there is a leak that must be found and repaired. “Topping off” a unit without fixing the leak is not only environmentally harmful but also technically damaging, as low refrigerant levels cause the oil to stop circulating correctly, eventually “starving” the compressor of lubrication and causing it to seize.
