“From start to finish, Euler at EVS Mechanical delivered exactly what he promised. He came to evaluate the same day I called. After coming out and doing a thorough analysis of the job, he scheduled it for the next morning, showed up on time with his crew, and completed the work in a few hours. The crew was tidy and friendly. The job involved moving a mini split unit to a new location on the wall to make room to install a Tonal. The job went exactly as described. No hiccups. … From the first call to the finished job, the whole process was faster than expected. This was the fastest and smoothest home improvement project I've done. I cannot recommend them enough.”

Mini split (ductless mini split)

A heating and cooling system that delivers conditioned air directly to specific zones without ductwork, consisting of an outdoor compressor and one or more indoor air handlers.

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.

Bay Area Specifics

Fog Belt (San Francisco, Daly City, Pacifica)

Mini splits excel here. Most homes need heat 9 months and cooling only a week or two. A mini split does both efficiently. No ductwork to lose heat through.

South Bay Valley (San Jose, Cupertino, Saratoga)

Summer temperatures hit 90-105°F. Multi-zone mini splits with higher BTU capacity are common. Proper load calculation matters most in these homes.

Older Homes (Pre-1950s)

Many Bay Area older homes have no ductwork, undersized ducts, or plaster-and-lathe walls. Mini splits avoid the cost and mess of cutting into walls. A small refrigerant line is all that's needed.

ADUs and Garage Conversions

Santa Clara, San Jose, and Sunnyvale are seeing a boom in ADUs. Mini splits are the standard recommendation — compact, efficient, independently controlled per unit.
