I am planning on installing my own Furnace, A-coil, and condenser. I am an electrician so purchasing these items may be tough. I have looked online and could go that way. Not being a licensed HVAC contractor it's hard to find someone to sell to me without gouging me on price. Has anyone dealt with online purchases and warranty issues? I spoke with one on line dealer and was told if a part goes bad mail it back and they will replace it if it is truly bad. Fine for small item not so good for say a motor or A- coil. How does it work at the local distributor. You go on a warranty call remove the bad part take it to the distributor who gives you a replacement part free of charge. What does the distributor do- bill Rheem for the warranty part, send the part back to Rheem for analysis? Before everyone tells me to have someone install it for me its not going to happen. I am certain most all HVAC mechanics can do a service change, recepticle installation, and most all residential electrical installations with a little research after all its not rocket science.
