Choosing the right mounting plates for your dual HVAC units is crucial for ensuring efficient operation, structural integrity, and longevity of your system. This comprehensive guide will walk you through the key considerations, different types of mounting plates, and best practices for installation. We'll also address some frequently asked questions to help you make an informed decision.
What are Mounting Plates for Dual HVAC Units?
Mounting plates, also known as base plates or support plates, are essential components used to securely attach dual HVAC units (such as two air handlers or condenser units) to a building's structure. They provide a stable and level foundation, distributing the weight evenly and preventing vibration or movement that could damage the units or the building itself. The type of mounting plate needed depends heavily on the size, weight, and specific requirements of your HVAC units and the building's construction.
Types of Mounting Plates for Dual HVAC Units
Several types of mounting plates cater to various HVAC system configurations and installation needs. These include:
-
Steel Mounting Plates: These are the most common type, offering durability and strength to support heavy HVAC units. They are typically galvanized or powder-coated for corrosion resistance.
-
Aluminum Mounting Plates: Lighter than steel, aluminum mounting plates are a suitable option for smaller, lighter units. They're often chosen for their corrosion resistance, particularly in coastal or humid environments.
-
Custom-Fabricated Mounting Plates: For unique installation requirements or unusual unit configurations, custom-fabricated mounting plates offer flexibility and precision. These are usually designed and manufactured by specialized metal fabricators.
How to Choose the Right Mounting Plate
Selecting the appropriate mounting plate involves considering several critical factors:
-
Weight and Size of HVAC Units: The mounting plate must be strong enough to support the combined weight of both units. Underestimating this can lead to structural failure.
-
Building Structure: The mounting plate must be compatible with the building's construction materials (e.g., concrete, wood framing). Appropriate fasteners must be used to ensure secure attachment.
-
Vibration Dampening: Some mounting plates incorporate vibration dampening features to minimize noise and vibration transfer to the building. This is especially important in residential settings.
-
Corrosion Resistance: In harsh environments, corrosion-resistant materials like galvanized steel or aluminum are essential to extend the lifespan of the mounting plate.
-
Accessibility for Maintenance: The mounting plate should allow for easy access to the HVAC units for routine maintenance and repairs.
What Size Mounting Plate Do I Need for Dual HVAC Units?
Determining the appropriate size depends directly on the dimensions and weight of the dual HVAC units. There's no one-size-fits-all answer. Consult the manufacturer's specifications for your units and the mounting plate supplier for guidance on selecting the correct size. Larger units invariably require larger, stronger mounting plates.
Are There Different Mounting Styles for Dual HVAC Units?
Yes, mounting styles vary depending on the installation location and building structure. Common mounting styles include:
-
Wall-Mount: Units are mounted directly to a wall using appropriate brackets and fasteners.
-
Roof-Mount: For rooftop installations, specialized mounting plates are used to secure the units to the roof structure, often with additional bracing for wind resistance.
-
Ground-Mount: Ground-mounted units require robust mounting plates and may need additional concrete footings or bases for stability.
How Much Do Mounting Plates for Dual HVAC Units Cost?
The cost of mounting plates varies considerably based on size, material, and complexity. Simple steel plates can be relatively inexpensive, while custom-fabricated plates or those with vibration dampening features can be significantly more expensive. Always obtain quotes from multiple suppliers before making a purchase.
Where Can I Buy Mounting Plates for Dual HVAC Units?
Mounting plates can be purchased from HVAC supply companies, industrial metal suppliers, and online retailers. It's essential to ensure the supplier provides plates that meet industry standards and are appropriate for your specific HVAC units and installation requirements.
By carefully considering these factors and seeking professional guidance when needed, you can ensure your dual HVAC units are securely mounted and operate efficiently for years to come. Remember, proper installation is key to preventing damage and ensuring the longevity of your entire HVAC system.
