With the HVAC Serial Number Lookup from United HVAC Motors, you can find exact motor specs, build dates, and compatible replacements in seconds. We combine factory data with detailed compatibility cross-references so you can choose the right blower motor the first time.
The serial number is located on the motor’s nameplate. Common places include the side of the motor housing (printed label or etched plate), the rear cap near the wiring harness, or inside your unit behind the blower access panel. Tip from United HVAC Motors: If the label is worn, snap a photo with good lighting. Even the first 6–8 characters are often enough for our lookup to identify your motor.
Yes. Our lookup works with serial numbers, model numbers, factory SKUs or OEM part numbers, and even partial codes. This ensures you can still find your motor even when the full serial isn’t visible.
What details will the lookup provide?
When you search with us, you don’t just get a code—you get the full picture: technical specs (HP, RPM, Volts, Phase, Rotation, Shaft size) and motor type (PSC or ECM). United HVAC Motors recommended blower motor equivalents, access to manuals, spec sheets, and wiring guides, plus extended warranty options when purchased through us.
This can happen when your original motor has more than one compatible replacement. Here’s how to decide: Pick the exact OEM match if listed. If multiple options appear, compare HP, RPM, voltage, and rotation. For ECM motors, confirm whether you need a module. Still unsure? Our tech support team can confirm shaft dimensions, mounting style, and best value option. Remember: when you buy at United HVAC Motors, you’re backed by expert support and extended warranty, so you’re never alone in the decision.
Don’t worry, it happens sometimes. Here’s what to do: re-enter the serial without spaces or dashes, double-check similar-looking characters (0/O, 1/I, 5/S), try the model number instead, and if still no match, simply upload your motor’s label photo or chat with us live. Our specialists will manually identify the motor, suggest blower motor equivalents, or offer retrofit kits. At United HVAC Motors, we’ll always find you a solution—even for discontinued models.
No. HVAC serial numbers only contain product information (batch, factory, date of build). Your privacy is never at risk.
Yes. Many manufacturers encode the production year and week in the serial. For example, “2318” = Week 18 of 2023. Our system automatically decodes this when possible, giving you insight into the true age of your equipment.
Does the lookup work for ECM motors?
Absolutely. Our tool covers both PSC and ECM motors. If ECM, results specify whether a separate module is required, if the replacement includes the module, and United HVAC Motors’ pre-verified ECM replacements for faster installs. We carry a wide range of blower motors and ECM solutions, all backed with extended warranties.
Every replacement we recommend is validated through OEM manufacturer catalogs, internal compatibility testing, and real-world field experience. When you buy through United HVAC Motors, you also get access to factory-authorized blower motor replacements, extended warranty coverage, and a dedicated support team to back you up before, during, and after installation. That’s why HVAC techs and contractors nationwide trust us for accurate, dependable replacements.
No problem. Our database is built to handle discontinued units. You’ll see direct replacements (if available), aftermarket blower motor equivalents that meet or exceed OEM specs, and retrofit kits for older systems (with brackets, harnesses, or adapters included). With United HVAC Motors, there’s always a path forward.
Yes! Once the lookup finds your motor, you can see real-time stock and pricing, access installation guides and spec sheets, and add to cart and buy instantly with extended warranty options. United HVAC Motors is your all-in-one solution: from serial lookup to ordering to tech support.
