General

What is a mini-split system?

A mini-split system is a ductless heating and cooling solution that consists of an outdoor compressor unit and one or more indoor air handlers. Unlike traditional HVAC systems, mini-splits don't require ductwork, making them perfect for room additions, older homes, or anywhere you want independent climate control. Zone mini-splits use advanced inverter technology to deliver efficient, whisper-quiet comfort.

How does a mini-split system work?

Mini-splits work by transferring heat between the outdoor and indoor units through refrigerant lines. In cooling mode, they remove heat from your space and transfer it outside. In heating mode (heat pump), they extract heat from outdoor air and bring it inside. Our systems use R454B refrigerant and inverter technology to adjust capacity based on your needs, providing superior efficiency compared to traditional systems.

What is SEER2 and why does it matter?

SEER2 (Seasonal Energy Efficiency Ratio 2) is the updated efficiency rating standard for HVAC equipment. All Zone systems feature 24 SEER2 rating, which means they use significantly less energy than traditional systems. A higher SEER2 rating translates to lower electricity bills and reduced environmental impact. Our 24 SEER2 systems can save you hundreds of dollars annually on energy costs.

Are Zone mini-splits Energy Star certified?

Yes! All Zone mini-split systems are Energy Star certified, meeting strict energy efficiency guidelines set by the EPA. This certification ensures you're getting a high-performance system that will save energy and money while reducing your carbon footprint.

Installation

Can I install a mini-split myself?

Yes! Zone systems are designed for DIY installation. Our pre-charged linesets eliminate the need for expensive HVAC technicians and specialized equipment. Most homeowners can complete installation in 4-8 hours with basic tools. We provide detailed installation guides and video tutorials to walk you through every step. However, you will need a licensed electrician to connect the electrical components to code.

Do I need a permit to install a mini-split?

Permit requirements vary by location. Most areas require permits for electrical work and outdoor unit placement. We recommend checking with your local building department before installation. Many customers handle the mechanical installation themselves and hire a licensed electrician for the electrical connection and permit.

How long does installation take?

For a single-zone system, most DIY installations take 4-8 hours. Multi-zone systems may take 8-12 hours depending on the number of zones. The pre-charged linesets save significant time compared to traditional installations that require vacuum pumps and refrigerant charging.

What tools do I need for installation?

Basic installation requires: cordless drill, hole saw (3-3.5"), level, screwdrivers, adjustable wrench, tape measure, and stud finder. For the electrical connection, hire a licensed electrician. All mounting hardware, brackets, and connections are included with your system.

Can I extend the linesets?

Yes! Zone offers lineset extensions in various lengths. Our pre-charged linesets can be extended using our extension kits, which include the proper refrigerant charge. This allows flexibility in unit placement without the need for vacuum equipment. Check our linesets page for available sizes.

Performance & Sizing

What size mini-split do I need?

Sizing depends on room dimensions, insulation, climate, and ceiling height. As a general guide: 9,000 BTU covers up to 350 sq ft, 12,000 BTU covers 350-550 sq ft, 18,000 BTU covers 550-1,000 sq ft, and 24,000 BTU covers 1,000-1,400 sq ft. For accurate sizing, consider factors like window count, sun exposure, and insulation quality. Our sizing guide provides detailed calculations.

Can a mini-split heat and cool?

Yes! All Zone mini-splits are heat pumps, meaning they provide both heating and cooling. They work efficiently in temperatures down to -15°F, making them suitable for year-round climate control in most regions. In heating mode, they're 2-3x more efficient than traditional electric resistance heating.

How efficient are Zone mini-splits?

Zone systems achieve 24 SEER2 efficiency, which is among the highest in the industry. This means they use up to 60% less energy than traditional HVAC systems. The inverter technology continuously adjusts compressor speed to match your exact needs, eliminating the energy waste from constant on/off cycling.

How quiet are mini-split systems?

Zone indoor units operate at just 19-42 dB depending on fan speed - quieter than a library or whisper. The outdoor units run at 48-58 dB, similar to normal conversation. Variable speed operation means the system rarely runs at maximum noise levels.

Can I use a mini-split in extreme temperatures?

Yes! Zone heat pumps are designed to operate efficiently in temperatures from -15°F to 115°F. The advanced inverter compressor maintains performance even in extreme cold, unlike older heat pump technology. For areas with sustained sub-zero temperatures, we recommend supplemental heating.

Operation & Maintenance

How do I control my mini-split?

Zone systems include a wireless remote control for easy operation. You can adjust temperature, fan speed, mode (heat/cool/dehumidify), timer settings, and more. Many units also feature WiFi capability for smartphone control and scheduling.

What maintenance is required?

Minimal maintenance is required. Clean or replace the indoor unit filters monthly during heavy use. Wipe down the indoor unit exterior and check that the outdoor unit is free from debris. Annual professional maintenance is recommended for optimal performance and longevity.

How often should I clean the filters?

Clean washable filters every 2-4 weeks during peak usage seasons. More frequent cleaning may be needed in dusty environments or homes with pets. The filters are easily removable and can be cleaned with water and mild soap. Clean filters ensure maximum efficiency and air quality.

What is the lifespan of a mini-split?

With proper maintenance, Zone mini-splits typically last 15-20 years. The inverter compressor technology experiences less wear than traditional on/off systems, contributing to longer system life. Regular filter cleaning and annual professional maintenance maximize longevity.

Technical

What voltage do Zone systems require?

Zone offers both 115V and 230V systems. Smaller capacity units (9K-12K BTU) are available in 115V (standard household outlet). Larger units (18K-24K BTU) require 230V. Check your electrical panel capacity before ordering. A licensed electrician can install the appropriate circuit and disconnect.

What refrigerant do Zone systems use?

Zone systems use R454B refrigerant, an environmentally friendly alternative to older refrigerants like R410A. R454B has a lower global warming potential (GWP) and meets the latest environmental standards. All linesets come pre-charged with the correct amount of refrigerant.

How far can the indoor unit be from the outdoor unit?

Standard linesets range from 16-25 feet. With extension kits, you can extend up to 50 feet in most cases. Longer distances may require larger diameter linesets or reduced capacity. Each additional 10 feet beyond the standard length may result in a small efficiency loss.

Can I add zones to my system later?

If you purchased a multi-zone system with available ports, you can add zones later by purchasing additional indoor units and linesets. However, you cannot convert a single-zone outdoor unit to multi-zone. Consider future expansion needs when choosing your initial system.

Do mini-splits dehumidify?

Yes! All Zone mini-splits remove moisture from the air during cooling operation. Most units also feature a dedicated dehumidification mode that removes humidity while maintaining temperature. This is especially beneficial in humid climates.
