What Is Mini Split?

A mini split (ductless mini split) is a heating and cooling system that delivers conditioned air directly to specific zones without ductwork. It consists of an outdoor compressor and one or more indoor air handlers, connected by a small refrigerant line.

When to call EVS:

You're adding a room or finishing a garage without ductwork
Your home has no existing ducts (common in older Bay Area homes)
You want independent temperature control in different rooms
A central system is oversized for your actual needs

Who this is for:

Homeowners in Santa Clara, San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Santa Cruz, Cupertino, Campbell, Saratoga, Los Altos, and Milpitas. Residential and light commercial.

Why EVS?

We do the math, not the guess.

Our Process

1. Call or Book Online

We answer. 1-2 hour callback if you leave a message. We'll ask about the space so the site visit is productive.

2. Site Visit + Load Calculation

We measure the room(s), check the electrical panel, evaluate wall and roof penetrations, and run a Manual J load calculation. This tells us exactly what BTU capacity you need — not a guess.

3. Custom Quote (Written, No Surprises)

You get a written quote with: equipment make and model, line set routing, electrical requirements, permit fees, timeline, and total price. Every number explained.

4. Permits + Scheduling

We pull the permit with your city. We schedule around your timeline — same week if available.

5. Installation

EVS technicians do the install. We test the system, commission it, and walk you through the operation — thermostat settings, cleaning, filter replacement schedule.

6. Follow-Up

We check in after the first heating or cooling season. Local service support — not a national call center.

Frequently Asked Questions

How long does mini split installation take?

Most single-zone installations take one day. Multi-zone systems typically take 1-2 days depending on the number of heads and line set routing complexity. EVS gives you a timeline upfront in your written quote.

Do mini splits work in Bay Area winters?

Yes. Mini splits are heat pumps — they provide both heating and cooling. Modern Mitsubishi and Fujitsu systems operate down to -13°F to -22°F. Every Bay Area winter is well within that range.

Do I need ductwork for a mini split?

No. Mini splits are ductless by design. The outdoor unit connects to indoor air handlers through a small refrigerant line. No ductwork required.

Will a mini split lower my energy bills?

Generally yes, compared to window AC units, portable heaters, or oversized central systems. Mini splits use inverter-driven variable-speed compressors that are more efficient than on/off cycling.

Do I need a permit in Santa Clara for mini split installation?

Yes. Santa Clara, San Jose, Sunnyvale, and most Bay Area cities require permits. EVS handles this — we pull the permit and schedule the inspection.

What size mini split do I need for a bedroom?

A typical Bay Area bedroom (120-200 sq ft) needs a 9,000-12,000 BTU unit. But this depends on ceiling height, window area, insulation, and sun exposure — which is why EVS does a load calculation rather than a square-footage guess.

Does EVS install Mitsubishi mini splits?

Yes. EVS Mechanical installs Mitsubishi, Carrier, Fujitsu, Daikin, Bosch, Lennox, Bryant, and Goodman mini split systems. We'll recommend the right brand for your needs and budget.

Can I add a mini split to one room without changing my existing HVAC?

Yes. Mini splits operate independently of your existing system. You can add ductless cooling and heating to a single room without touching the rest of your HVAC.
