(Redirected from EFI System partition) The EFI system partition (ESP) is a partition on a data storage device (usually a hard disk drive or solid-state drive) that is used by computers adhering to the Unified Extensible Firmware Interface (UEFI).
As much as 80 to 90% of the electrical energy used by an air compressor is converted to heat. A properly designed heat recovery unit can recover 50 to 90% of this heat for heating air or water.
Well maintained compressors have been know to last 20 years, but average is about 15 years. Given where you are, take it from someone that decided to spring for the High Efficiency 14 Seer (outside unit is twice the size as my old one) and has cut my power bill almost in half. I replaced mine almost 3 yrs ago, (whole thing, coils and all) and you will probably spend $1500-$2000.
