Public Service Announcement from your Friendly Neighborhood HVAC Tech.

A Public Service Announcement.

Current mood:amused

Thermostatic expansion valves, super-heated gasses, sub-cooled liquids, and how on God's green Earth am I going to get the delta-T that I need with this antique equipment?  These are some of the things that fill my head during the days while at work.  August is here, and occasionally Ra, or whoever the "Sun God" is even decides to scorch places like Seattle with triple digits.

     Below, you'll find a sample of  of a conversation between me, and a less than mechanically apt customer.  This is typical of what happens when I first initiate a conversation about their air conditioning equipment:

"I think it needs some "freon" in it."
"When was the last time you changed your filter?"
"I put them three month filters in there!"
"When was the last time that you changed it?"
"Well, last time a guy was out here-he just put some freon in it."
"SIR, PLEASE SHOW ME YOUR AIR FILTER!"

    I don't have any control over the quality of the equipment available in the residential air conditioning market, materials have been stretched thin-literally.  Heat transfer takes place through forced air flow across copper tubing, to be simple about it, and in the name of energy efficiency, and going green this copper tubing has been stretched thin.  Often what makes your air conditioner energy efficient also makes it scrap metal after too few Summers.

     But if every one of you would take the time to change your air filters regularly, and hose down your condenser(the out doors portion of the air conditioning system) regularly with pressurized water-then you'd see considerably LESS of ME, and I'd make less money.  There now, I'm a public servant-so if you assault me it's a FELONY!
