System replacement

When repair stops paying off

Nobody wants this purchase. So here is the math we use, the price range before anyone visits, and what the monthly payment looks like if you spread it out.

The five thousand rule

Multiply the repair quote by the age of the system. Under five thousand, repair it. Over, and you are renting time on a unit that is going to ask again next summer.

Repair it3,600

A $400 capacitor and contactor job on a nine year old system. Cheap, and that unit has years left in it.

Replace it12,600

A $900 compressor repair on a fourteen year old system. The next failure is already on its way, and R-410A keeps climbing.

We will still repair the second one if you ask. Some years that is the right call, and we say so out loud.
