Boyce's Air-Conditioning Refrigeration Department

If you are a Refrigeration or Air-conditioning mechanic the homepage of the Air-conditioning Refrigeration Institute will be useful:


American Society of Heating Refrigeration Air-conditioning Engineers


Refrigeration Service Engineers Society


You can find the Environmental Protection Agency at this link


You can probably find anything in construction and building from this page and the links there.

Refrigeration AC mechanics and Appliance techs should find something of interest at the HVAC MALL, They have a lot to offer.


The newsgroup Sci.engr.heat-vent-ac has a great webpage, thanks to Elitesoft, with a lot of information and links to other pages.


Some other HVAC related web sites.

Trouble Shooting Information

Before attempting to check or repair any electrically operated unit or appliance please, read the section on electrical safety first.

I do not recomend that untrained, inexperienced individuals attempt to repair or replace AC units or parts of them, but if you have the need to then, please be safe to yourself and the environment. If you plan to remove the covers then, turn off the power first. If you connect gauges to the unit, then when removing them valve off the high side first and discharge the refrigerant from the hoses into the system not the air. If you need to add refrigerant, then repair the leak first. If you have to remove the refrigerant, then use a recovery unit .If you recover refrigerant, then do not overfill the cylinders, they have pressure relief valves, but if it pops off, it could cause serious injury or death. Help make this little globe of ours a safer, healthier place for us and our children.

Don't scoff at the idea that refrigerant causes damage to the environment, go to the Air-Conditioning Refrigeration Institute Government Affairs Section, under Issues Affecting the HVAC/R Industry, then read the ARI white paper: Policy on Global climate change.

If you have questions, we will try to answer them or get the answer to them as time permits, just click on my name to email a message.
