In January the EPA mandated a 45% reduction in future production of R-22 in line with the scheduled phase-out. Prices immediately doubled nationwide. Sad to see it happen because I think 22 kicks all over 410a. we are seeing so many leaks in coils and pressure problems becuause it...

anyone coming across this problem can refer to these videos on low voltage and high voltage troubleshooting at the contactor you tube vid high voltage http://www.youtube.com/watch?v=ZArkm-OkF0g you tube vid - low voltage check at contactor http://www.youtube.com/watch?v=IALLkqXygsU...

thats right on. the aluminum is the outer shell with copper piping inside where the pressure is. take a look at this a coil in the video here http://www.youtube.com/watch?v=dkbsuo6w5aI you can see a rust/water line where the backed up drain was. I wouldnt worry too much. That coil sweats...

that's good advice back in the day we were told to hawk those like crazy. I always hated it because it was a way to generate more service calls for the company. Now I just teach people how to check their condensate drains themselves and clean them out. BTW if that float valve closes it shuts...

along with that great advice I would rule out the thermostat and low voltage wiring issues. 1. pull the thermostat cover off of the wall. touch red to green wires together. does the blower motor come on at all?? does it stay on if you put a wire nut on them? if so than you have a...

So the outdoor fan motor will not come on in cooling or heating right? kok328's advice is right on. 1. I would pull power to the outdoor unit - you tube vid on how here- 2. with stick or long screwdriver try and move the fan blades. are they tough to turn or move freely? 3. if tough...

There are a lot of DIY friendly A/C fixes and there are some that just flat out need a professional. At least you wont ever have that problem again and have to pay through the nose!! I got into this business after my parents were taken by some dirtbag A/C techs. Once I got into the trade I...

check on the ask me help. gotcha some info

this door trick is a useful way I find to narrow the leak down to a return or supply line. If there are multiple leaks the only real way is to get up close and look. good luck

1. do you have a split system or package unit on the rooftop (im thinking you referred to a rooftop (packaged) unit. what size unit do you currently have (thinking 5 tonish) 2. Any chance of building in a soffit in the bathroom or using flex to move the return line. 3. is the 'in the way...

If you are just starting to notice the dust and insulation in the home I would definately rule out a duct leak. Since the unit is new there is a possiblity that a leak developed during installation or right after, especially if there is no history of the problem. If you can rule that out...

The motor will probably work ok for awhile. Just curious why you dont replace it with an actual blower motor? The two motors are cooled differently via airflow. Blower motors have openings on the side as the air is pulled across them into the squirrel cage and condenser fan motors air is...

its not the metal grinding from the squirl cage fan is it? ive heard a lot of godawful and that is definately one you dont forget. once the blower motor gets up to speed maybe the inner squirl cage is touching the housing. If the mounting screws (and housing) for the blower motor is/are...

Steve, sorry, short version not the novel... remove squirrl cage assembly and it all slides out

After pulling power to the air handler discharge the run capacitor for the blower motor. Just use and insulated screwdriver and touch both terminals WHILE HOLDING INSULATED HANDLE. TAKE PICS OF EVERYTHING. I still do this on wiring setups to this day Note wiring setup you can draw it...
