What are Ceiling Cassettes?

These systems are the premier choice for both residential and commercial spaces where floor and wall space are at a premium, offering a clean, architectural look that blends seamlessly with any decor.

Having a ceiling cassette collection is vital for projects requiring high-capacity cooling without the invasive ductwork of central air. They provide targeted climate control for open-concept living areas, offices, or master suites while maintaining a discreet profile. To ensure a complete installation, our collections include (or have available) the necessary line sets, control wires, and mounting brackets required to get your system up and running efficiently.

Technical Highlights & Specifications

For HVAC buyers looking for data-driven performance:

  • Efficiency Ratings: Our systems meet modern SEER2 and HSPF2 standards, highlighting significant energy savings and lower utility costs.
  • Refrigerant Updates: We stay ahead of industry regulations with a shift to R454B or R32 refrigerants, ensuring your inventory is modern, compliant, and eco-friendly.
  • Voltage Options: Systems are available in multiple power configurations; remember to check your specific 115V vs. 230V requirements before purchase.
  • Advanced Airflow: Many models feature independent vane control and built-in condensate pumps for flexible installation in tight plenum spaces.

Operational Benefits

Ceiling cassettes offer 3-5 distinct advantages for both Residential and Commercial customers:

  • Discreet Design: Perfect for high-end residential interiors where visible wall units are undesirable.
  • Space Optimization: Reclaims wall and floor space in crowded commercial or retail environments.
  • Uniform Air Distribution: The 4-way discharge prevents "hot spots" in large, open-concept rooms.

Whisper-Quiet Operation: Advanced fan designs ensure conditioned air is delivered at library-quiet decibel levels.

Find Your Perfect Match: The HVAC Supplies BTU Sizing Guide

Selecting the correct BTU (British Thermal Units) capacity is the most critical step in ensuring your ductless system operates at peak efficiency while providing maximum comfort. At HVAC Supplies, we aim to eliminate the guesswork; an undersized unit will run constantly and drive up utility bills, while an oversized unit will cycle too frequently, leading to poor dehumidification and unnecessary wear.

Below is our comprehensive sizing guide designed for HVAC Supplies customers, featuring direct links to our high-efficiency mini split collections.

6,000 BTU
150 – 250 sq. ft.
Small bedrooms, home offices, nurseries, or high-efficiency “tiny homes”.
9,000 BTU
250 – 450 sq. ft.
Standard bedrooms, guest rooms, mid-sized offices, and insulated sunrooms.
12,000 BTU
450 – 600 sq. ft.
Master bedrooms, small living rooms, kitchens, or studio apartments.
18,000 BTU
600 – 1,000 sq. ft.
Large living rooms, master suites, or insulated 1-car garages.
24,000 BTU
1,000 – 1,200 sq. ft.
Open-concept main floors, 2-car garages, or small retail boutiques.
28,000 BTU
1,200 – 1,400 sq. ft.
Large open floor plans, community halls, or multi-room office suites.
30,000 BTU
1,400 – 1,500 sq. ft.
Large workshops, pole barns, or medium-sized commercial floor plans.
36,000 BTU
1,500 – 1,700 sq. ft.
Large residential open areas, showrooms, coffee shops, or fitness studios.
42,000 BTU
1,700 – 1,900 sq. ft.
Commercial spaces, restaurants, medical clinics, or church halls.
48,000 BTU
1,900 – 2,100 sq. ft.
Very large open residential areas, small warehouses, or banquet facilities.
55,000 BTU
2,100 – 2,400 sq. ft.
Large retail stores, high-ceiling industrial spaces, or commercial grow rooms.
60,000 BTU
2,400 – 2,800+ sq. ft.
Large warehouses, multi-office buildings, or massive high-ceiling estates.

When to "Size Up" Your Unit

While the table above provides a baseline for standard rooms, specific environmental factors at your job site may require a higher BTU capacity:

•
High Ceilings: If your ceilings are 10 feet or higher, you are cooling a larger volume of air. We recommend increasing your BTU choice by 20%.
•
Insulation Levels: For older buildings with single-pane windows or poor insulation, opt for the next size up to ensure the system can maintain the set temperature.
•
Kitchen Installations: Cooking appliances generate significant heat. If the unit is for a kitchen area, add 4,000 BTUs to your total calculation.
•
Heavy Sun Exposure: Rooms with large south-facing windows act like greenhouses. Increase your BTU capacity by 10-15% for these spaces.
•
High Occupancy: If the area regularly hosts more than two people (such as a conference room), add 600 BTUs per additional person.

Frequently Asked Questions

Q. How much ceiling clearance is required for a cassette installation?

A. Most standard cassettes require approximately 10 to 12 inches of clearance above the ceiling joists. However, we also stock "Slim" models designed for tighter spaces. We recommend measuring your plenum space before ordering and calling us at 1-800-543-8933 if you need help verifying a specific model's dimensions.

Q. Does a ceiling cassette require a specialized drain pump?

A. Most of the ceiling cassettes in our collection come with a built-in condensate lift pump. This allows the system to pump water vertically out of the tray and away from the unit, which is essential for recessed ceiling installations where gravity drainage isn't an option.

Q. Can I use a ceiling cassette in a multi-zone system?

A. Absolutely. Ceiling cassettes are highly versatile and can be used as a single-zone system or as one of several "heads" in a multi-zone configuration. We offer pre-matched bundles from brands like Cooper & Hunter and ACiQ to ensure perfect communication between the cassette and the outdoor condenser.

Q. What is the difference between a 1-way and a 4-way cassette?

A. A 1-way cassette is designed to fit between standard ceiling joists and blows air in one direction, making it perfect for narrow hallways or smaller rooms. A 4-way cassette provides 360-degree airflow and is better suited for large, open areas where you need to distribute air in every direction simultaneously.

Q. Why is professional installation required for the warranty?

A. Because ceiling cassettes involve electrical wiring, refrigerant line flaring, and precise ceiling cuts, manufacturers require installation by a licensed HVAC professional. This ensures the system is installed to local code and that your manufacturer warranty remains valid for its full term.
