Secure Outdoor Support for Larger MRCOOL® Mini-Split Condensers.
Need a cleaner, space-saving way to mount your compatible MRCOOL® outdoor condenser?
The MRCOOL® Condenser Wall Mounting Kit is designed to support compatible 24K to 36K BTU MRCOOL® ductless split system condensers, helping lift the outdoor unit off the ground and keep the installation area neat, secure, and better protected.
Wall mounting can help reduce exposure to ground-level debris, standing water, snow buildup, landscaping interference, and uneven surfaces.
Built for larger-capacity ductless systems, this kit is a practical installation accessory for homeowners and installers who need a secure outdoor mounting solution.
It is especially useful when ground space is limited or when a cleaner exterior installation layout is preferred.
Strong support. Cleaner placement. Built for compatible MRCOOL® systems.

Questions, answered
Everything homeowners ask before buying a MRCOOL® system.
Installation
Do I need an HVAC technician to install this?
No. MRCOOL® DIY systems are designed for homeowner installation. The pre-charged Quick Connect® line set means there's no refrigerant handling, no vacuum pump, and no special tools or license required.
How long does installation take?
Most single-zone systems go in within a few hours: mount the indoor air handler, set the outdoor condenser, connect the pre-charged line set, and power it on.
Do I need an electrician?
The system needs a dedicated circuit. Most homeowners have a licensed electrician add the breaker and disconnect — everything else you can do yourself.
Sizing & compatibility
What BTU size do I need?
As a rule of thumb: up to 400 sq ft → 9–12K BTU, 400–600 sq ft → 12–18K, 600–1,000 sq ft → 18–24K. Use the room-size guide above and factor in insulation, ceiling height and sun exposure.
Will it heat in winter?
Yes — these are heat pumps, so they heat and cool. Many MRCOOL® systems keep heating in sub-freezing temperatures; check each model's spec sheet for its low-temperature heating range.
115V or 230V — which do I need?
9K–12K units are usually 115V (standard outlet circuit); 18K and larger are typically 230V. The voltage is shown in the product options and specifications.
Warranty & support
What warranty is included?
MRCOOL® systems carry manufacturer warranty coverage — typically 5–10 years on major components when you register your system after installation.
How do I get help choosing or installing?
Email support@coolheatdirect.com — our U.S. team replies within one business day with sizing, voltage and compatibility help.
Shipping & returns
How fast does it ship?
Most products ship in 3–5 business days with free curbside delivery in the continental U.S. The freight carrier calls to schedule your delivery.
Can I return it?
Returns are accepted within 30 days on new, unopened items in original packaging. A restocking fee may apply to HVAC equipment — we always confirm before issuing a return authorization.
