A mini split for garage or addition in Longmont is one of the most popular retrofit projects we do, it turns unused square footage into comfortable, usable living space.

Ductless Mini Split System Installation

A ductless system has two main parts: an outdoor condenser and one or more indoor air handlers. A small line set, usually just a few inches wide, connects them through the wall. No bulky ductwork, no major demolition.

This makes ductless a great fit for homes without existing ducts, and for retrofit projects where running new ducts would be expensive or invasive. We route line sets cleanly, handle the electrical hookup, and charge the refrigerant to manufacturer specs so your system runs efficiently from day one.

Single-Zone and Multi-Zone Mini Split Setup

A single-zone system pairs one indoor air handler with one outdoor condenser. It’s perfect for cooling or heating a specific space, like:

Bedrooms
Home offices
Sunrooms
Basements
Bonus rooms
Workshops

Single-zone units give you independent temperature control, quiet operation, and high energy efficiency, all with minimal installation requirements.

A multi-zone system connects multiple indoor air handlers to one outdoor condenser. Each zone gets its own thermostat, so everyone in the house can set their own comfort. Multi-zone mini split installation is ideal for whole-home comfort, letting you customize heating and cooling from room to room without wasting energy on spaces nobody’s using.

Whether you need simple mini split AC installation in Longmont for one room or a full multi-zone setup, we size and install it right.

How We Clear It

The Right Tool, Not Just the Nearest One

Mini Split Sizing and System Consultation

Bigger isn’t always better with ductless. An oversized unit short-cycles and wastes energy: an undersized one struggles to keep up. That’s why proper sizing matters.

We use a load calculation that accounts for your square footage, insulation, windows, ceiling height, and sun exposure to figure out the right BTU capacity for each zone. Then we help you pick the best mini split system for your Longmont CO home based on your goals and budget.

Mini Split Repair and Maintenance

Even the best systems need service now and then. Our maintenance keeps your unit efficient, and our repair team gets things back on track fast when something goes wrong. More on repairs below.

Energy Efficiency and Heat Pump Technology

A ductless heat pump in Longmont both heats and cools with a single system. Variable-speed inverter technology ramps output up or down instead of blasting on and off, which means quieter operation, steady comfort, and lower energy bills.

High SEER ratings translate to real savings, and zoned control means you’re not paying to condition empty rooms. Well-known manufacturers like Mitsubishi and Daikin build reliable inverter-driven systems with strong cold-climate performance, good options to consider for our Front Range weather.

Why Choose EP Plumbing for Bathroom and Kitchen Plumbing in Longmont?

We’re licensed and insured in Colorado. Our plumbers are trained, background-checked, and up to date on plumbing codes and permitting requirements. That protects your home and your investment.
