Warranty & Coverage FAQs
What warranty comes with MRCOOL systems?
MRCOOL systems include a manufacturer-backed warranty that typically covers the compressor and parts for a defined period. Coverage varies by product line and whether the system is installed as DIY or professionally installed.
Do MRCOOL DIY systems really include a warranty?
Yes. MRCOOL DIY systems are designed for homeowner installation and remain fully warrantied when installed according to MRCOOL’s instructions using approved components.
How does DIY vs Pro installation affect warranty coverage?
DIY systems maintain warranty coverage when installed by the homeowner.
Pro-install systems generally require installation by a licensed HVAC professional to qualify for full coverage. Each MRCOOL product line has specific requirements.
What is covered under the compressor warranty?
The compressor warranty covers defects in materials or workmanship of the compressor itself. Some MRCOOL models qualify for extended or lifetime compressor coverage when properly registered.
What does the parts warranty include?
The parts warranty covers eligible internal components such as control boards, motors, sensors, and valves. Labor, refrigerant, and shipping are typically not included.
How long is the MRCOOL warranty period?
Warranty terms vary by model and product family. Common coverage periods include:
- Compressor: up to lifetime (select models)
- Parts: commonly 5–10 years
Always refer to the specific model’s warranty documentation.
How do I register my MRCOOL warranty?
Warranty registration is completed online through MRCOOL after installation. Registration is usually required within a set timeframe to receive full coverage, including any extended compressor warranties.
What can void my MRCOOL warranty?
Common reasons a warranty may be voided include:
- Improper installation
- Use of non-approved components
- Modifying the system
- Failure to follow installation or maintenance guidelines
Does using longer or non-standard line sets affect the warranty?
Using line sets outside of MRCOOL’s approved lengths or specifications can affect system performance and may impact warranty coverage. Always follow model-specific guidelines.
Is labor covered under the MRCOOL warranty?
No. MRCOOL warranties typically cover parts only. Labor, refrigerant recovery, diagnostics, and reinstallation costs are the responsibility of the homeowner or installer.
Are multi-zone systems covered differently than single-zone systems?
Coverage terms are similar, but multi-zone systems have additional installation requirements. Proper sizing, line-set configuration, and installation practices are essential to maintain warranty eligibility.
What if I’m not sure whether my installation qualifies for warranty coverage?
That’s where expert guidance helps. Reviewing your system choice, installation method, and components before purchase can prevent issues later.
Where can I find warranty details for my specific MRCOOL model?
Each MRCOOL product line has its own warranty documentation. Refer to your product manual or the model-specific warranty section in the bCOOL Learning Center.
