What Is a 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.

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

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

What Our Clients Say
Real reviews from real customers. Every job backed by upfront pricing, licensed technicians, and a commitment to getting it right.
“EVS Mechanical is a great HVAC company! They were very professional, on time, explained everything and had a very competitive price. They found asbestos and we had to replace our entire furnace and duct work — it was done in a week. They filed the permits and handled everything. I highly recommend them.”

Frequently Asked Questions
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.
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.
No. Mini splits are ductless by design. The outdoor unit connects to indoor air handlers through a small refrigerant line. No ductwork required.
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.
Yes. Santa Clara, San Jose, Sunnyvale, and most Bay Area cities require permits. EVS handles this — we pull the permit and schedule the inspection.
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.
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.
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.
Yes. EVS provides ongoing maintenance and repair for every system we install. Local service team — not a warranty call center.
