Frequently Asked Questions
No, MRCOOL systems do not need to be vacuumed, but their filters should be regularly cleaned or replaced to maintain efficiency.
No — MRCOOL is an American company based in Hickory, Kentucky, though some of its products or components are manufactured overseas.
A mini-split generally stops working efficiently below around 5–14 °F (-15 to -10 °C) for heating, depending on the model, and may also struggle in extreme heat above 115–120 °F (46–49 °C) for cooling.
The “$5,000 rule” for AC/HVAC means: multiply the age of your system (in years) by the estimated repair cost; if the result exceeds $5,000, replacing the unit is likely the smarter choice.
Yes, most mini-split air conditioners can work in 100 °F (38 °C) weather, though their efficiency may drop slightly and performance can vary by model.
The 20-degree rule for heat pumps means a heat pump can efficiently provide heat when outdoor temperatures are above roughly 20 °F (-7 °C), below which supplemental heating may be needed.
