Description

Supplying Demand makes replacement parts for appliances and HVAC systems, plus the tools, hardware, plumbing supplies, and apparel to finish the job. From the laundry room to the kitchen to the furnace, our catalog is built around the repairs homeowners and technicians run into every day. Whether it's your first repair or your thousandth service call, we make the parts that keep it running. Start with your complete model number. It's on the appliance's rating plate, and it determines fitment. Often, yes. With the right tools, many of these are practical repairs. Disconnect power and shut off gas or water first, and call a qualified technician if you're unsure. The cost of repair. We make it practical to fix what you already own, and we try to use reusable or recyclable packaging to cut waste. Do gas furnaces and electric air handlers use the same parts? Blower motors, limit switches, transformers, and filters are shared designs, though each is model-specific. The heat parts differ: gas furnaces use igniters, flame sensors, and gas valves; electric heat uses heat strips and sequencers. Where do I find the model number on my HVAC system? On the outdoor unit, look on the side panel. On the indoor unit, check the cabinet or its door. Use the model number, not the serial number. Which HVAC repairs can I do myself? With the power off, filters, drain lines, and many controls and motors are homeowner jobs. Refrigerant work and live-voltage checks are not. Federal rules prohibit venting refrigerant during service, so the sealed system goes to a licensed tech. My heat comes on, then shuts off. What should I check? Start with the filter. A clogged filter can overheat the system and trip the limit switch, gas or electric. On a gas furnace, a dirty flame sensor can shut the burners off within seconds. If both check out, test the limit switch. My outdoor unit hums, but the fan won't spin. What's wrong? With the power off, make sure nothing is jamming the blade. If it spins freely, a failed capacitor is a common cause, then the fan motor. Capacitors can hold a charge with the power off, so leave testing them to a licensed tech.

  • What can I say about screws?
They came in a plastic container. They were the size I ordered. They worked. I have extras.

  • Better than a hardware store
Nice and sturdy no defects

  • Too small
They aren't as long as advertised and the head on them is so small it keeps slipping out of the bit on my drill.
