Figure out the symptom
A part that looks bad might just be a sign of another issue in the system. Tell us what’s going on and any error messages you see, so we can check the system before deciding what needs to be replaced.
Homeowner service guide
MARS HVAC parts guide.
Got a question about a MARS part in your HVAC system? Start with your equipment model and the part info. We need to make sure it fits and know what’s causing the issue before picking a replacement.
Know your equipment
MARS replacement parts and homeowner info
You can now get MARS product info through RectorSeal. The MARS lineup has HVAC and electrical replacement parts, and you’ll find Amrad capacitor info in the official collection too. Matching a motor or capacitor means looking at how it’s used and its ratings, not just the brand name on the old part. Always check if it’s available and right for your specific equipment.
Give us your HVAC unit model and any past repair paperwork. If you already got a part number from a tech, send that in with your request instead of taking out a part to look at it.
Parts to check out: HVAC electrical products, motors, capacitors, and related replacement parts.
Manufacturer resources
Use the official info for your model.
Check the equipment model, serial number, install date, and registration papers before looking at coverage. A manufacturer link doesn't mean a repair, replacement part, or labor is covered. Double-check the terms that apply to your equipment.
For help from the manufacturer, use the company contact below. Have your equipment or part’s model, serial number, when you bought or installed it, and proof of purchase ready. What’s covered and how to file a claim depends on the product’s terms.
