Hello,I am a retired mechanical engineer with 56 years in this business. I will go in depth with you, and up to a 6 hour time limit.
All I ask is please select the ***RATING LINK*** at the top of your page before leaving, that is the only way I am credited through the site.
Rating does not affect your charges nor ability to refund if not satisfied. If you can agree to that, lets continue by all means.
Evaporative coolers are best drained and cleaned at the end of every cooling season.
lacking that, the recommendation for deodorants would be like having a deodorant for men that said you never need to take a bath. That would be ludicrous of course.
No telling what some sales people will say to sell a product.
Stay in touch as needed. When you have all that you need please select the 'finish and rate your expert' link near the top of your page to close the question, I will appreciate it.
