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 about yours:
- 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

Clean work. Clear prices. People who answer after the install.
Customers remember the details: showing up, explaining the options, protecting the home, and standing behind the system later.
“We converted our home from a gas furnace to a full electric heat pump system and upgraded to a two-zone setup, giving each floor its own temperature control. EVS guided us through every step, explained our options clearly, and made a complicated project feel straightforward. The installation was clean and completed with a high level of craftsmanship — and their pricing was the most competitive of all the quotes we received.”

“Really impressed with EVS Mechanical — they earned every one of these five stars. The heat pump they installed has been incredibly efficient, and our energy bills have actually dropped. They showed up exactly when they said they would and were careful with our home during the installation. Would absolutely recommend EVS to anyone in the Bay Area.”

“EVS Mechanical made what could have been a stressful process incredibly smooth. They diagnosed and repaired our HVAC system quickly and got everything running again. They didn't just do the work — they made sure we understood what was happening and why. Honest pricing, no upselling on things we didn't need. If you need HVAC work done right, call EVS Mechanical.”

“I called EVS for a regular furnace service and they were here very quickly. They performed the service in one day and also discovered the very old condensate pump was not working properly causing water to pool around the furnace. They replaced the pump the next day. Would definitely use their services again.”

“Euler and his team were able to replace our 23 year old attic Carrier furnace after our existing unit's heating chamber failed. I called him at 10am, and he was at my house by 11am, diagnosed the issue and found a new replacement unit and had it installed by 4pm. Very friendly and great price too.”

“EVS Mechanical is a great HVAC company! They were very professional, on time, explained everything and had a very competitive price.

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.
Earthquake Safety
Wall-mounted air handlers are lightweight and secured per code. Outdoor units are anchored. Meets all Bay Area seismic requirements.
