  1. What products are available in the spare parts generator?
    We have information for most of our water source heat pumps (WSHP), air source heat pumps (ASHP), furnace, boilers, tankless units, and storage tanks. We are always updating the site with new and legacy product part information.
  2. What information do I use to lookup parts for each product?
    For WSHP use serial number for the most accurate information. For ASHP and Furnaces you will need the full model number including dashes. For boilers, tankless, and storage tanks you can use a partial model number or material number to look up parts.
  3. I am looking for parts for a WSHP but no results are coming up?
    Please ensure that the SN or MN you are using is correct and belongs to one of our Water Sourced Heat Pump (WSHP) products. Using the serial number is the preferred option when looking up WSHP parts and the complete serial number must be entered for this search to work. Units manufactured after April 1st, 2014 have SN’s which are 26 digits long. For example, 2940-658-000001-7735052404. Current model numbers are 40 digits long. For example; EC096-3VTC-FFTBUA-XATXXXXXX7XXXX3BXXXSBA. For legacy products, the SN can be 26, 8 or 9 digits long. For example, 3540-104-000003-T111M41207, RG122245 or SM133830T. If you have verified the MN and/or SN and are still not getting results, or have any additional inquires, please contact us at or 800-283-3787.
  4. When searching by model number is it necessary to enter the complete model number WSHP, ASHP, boilers, and tankless?
    When looking by model number for WSHP, Boilers, and Tankless you can shorten the search. We recommend providing at least the first 10 digits of any given model for WSHP. Example - SM048-1VTC. With boilers and tankless you can use the first few letters. Example - GB142, or ZBR. For the air to air product you will have to put the full model number including dashes. You can find the full list of model numbers in the instructions linked above. Reminder - for WSHP serial number is always the most accurate lookup option for spare parts.
  5. Can I order parts via the spare parts generator (SPG)?
    No, the SPG is intended to find part numbers and list price for spare parts of a unit and to create a list of those spare parts. We have not integrated an order processing system into the website. To order parts, please consult your local rep or distributor.
  6. Can I also check availability online?
    Yes! Availability is now listed in the column labeled Qty on Hand. Please note that this is updated twice a day. If you see low quantities it is recommended you call customer service to verify availability.
  7. Can I check for warranty status (Warranty at a Glance)?
    Yes, only for our Water-Sourced heat pump (WSHP) products. You will need the SN of the unit and can enter it at the link above labeled warranty. For 2940 serial numbers it will only show the base warranty included with the unit. For 3540 and all other serial numbers it will show the extended warranty.
  8. Why are filters not showing prices?
    We do not sell filters but keep it listed in the spare parts list to provide their dimensions.
