Making an OLD A/C unit more efficient. How much will this help?

Hi Neighbor



You might use the condensate drain water from your A/C evaporator. It is distilled water and will cause less scale buildup... and you won't need a shutoff valve.

errrr ahem ! cough cough ..... exxxxxcuse me, Mr 10% here is collecting royalties for this idea! I have faith in the honour code among Fridgies!
Covered for static as well as transport a/c .....

Swiss bank a/c details to follow .....

Seriously, you may need small pump and devise a float level switch - you may not always have sufficient water inthe drip pan to run pump continuously

Yuk Yuk
