Mitsubishi HVAC in Palo Alto

Palo Alto's Eichlers are a classic Mitsubishi job: post-and-beam ceilings rule out ducts, so a multi-head M-Series preserves the open architecture.

Mitsubishi options for your home

Start with the space you want to heat and cool, or compare equipment layouts.

Palo Alto has a heavy concentration of Eichler homes, and that is a big reason Mitsubishi sees so much use here. Eichlers have post-and-beam open ceilings that rule out adding conventional ductwork, and their original radiant-slab heating, copper tubing cast in concrete, has mostly failed beyond repair. A multi-head Mitsubishi mini-split is the usual answer: one outdoor condenser, indoor heads positioned to preserve the open-ceiling look that defines the house. We have worked through a number of Eichler retrofits and the approach is well practiced.

Beyond the Eichler tracts, Palo Alto customers tend to want high-efficiency equipment and code-correct installs, and the M-Series fits that in the Spanish-revival and Mediterranean stock of Old Palo Alto and Crescent Park where the goal is to add cooling without disrupting heritage layouts. For homes with sound ducts, a premium Daikin ducted heat pump is also on the table, and we lay out both. The honest tradeoff is cost. Mitsubishi is premium equipment, and in this city that aligns well with what most homeowners are already after.

Palo Alto runs its own municipal utility, CPAU, which has historically been ahead on heat pump incentives. We verify CPAU eligibility on every estimate here and handle the application. Programs and amounts change, so we confirm what is actually paying rather than quoting a figure that may have moved.

Mitsubishi work we do in Palo Alto

Multi-head ductless retrofits in Eichlers. One Mitsubishi outdoor condenser feeding heads placed to keep the post-and-beam ceilings open and uncluttered. This is the established fix for an Eichler whose radiant slab has failed, giving real heating and cooling without compromising the architecture.

Premium ductless in heritage Spanish and Mediterranean homes. In Old Palo Alto and Crescent Park, we add Mitsubishi mini-splits where central ducts would disrupt preserved original layouts. The work is planned around keeping line sets discreet and heads positioned to respect the room.

Code-correct installs with CPAU rebate filing. Palo Alto customers expect Title 24 compliance done right and the rebate paperwork handled. We verify CPAU eligibility on each project, file the application, and keep the install documentation clean for inspection.

Multi-zone diagnostics and head service. On existing Mitsubishi systems we troubleshoot a head that drops out while others run, clear condensate pumps, read the controls, and clean coils and blower wheels so each zone holds its rated output.

Mitsubishi in Palo Alto: common questions

You are based in San Ramon, do you regularly come down to Palo Alto?
Yes, Palo Alto and the mid-Peninsula are a normal part of our route, and Eichler work in particular brings us down here often. Call and we will give you a real arrival window. Same-day is best effort, not a promise.

How does the Mitsubishi warranty work on an Eichler retrofit?
As a Mitsubishi Electric Diamond Contractor, we register your M-Series or P-Series system for the Mitsubishi Electric 12-year parts and 12-year compressor limited warranty (the HM, WR, HX and WX wall-mounted series top out at 10 years). We register all indoor and outdoor units within 90 days of installation. This coverage applies to a single-family home while the original owner continues to live there and is not transferable. Our standard workmanship warranty is 2 years. Repairs carry a 1-year warranty. Mitsubishi's equipment reliability is part of why we recommend it for these homes. You want a system you are not opening up again, since the heads are positioned to protect the architecture.

Is the radiant slab worth trying to fix instead of going ductless?
Almost never. Original Eichler radiant heat is copper tubing cast into the concrete slab, and once it leaks it is effectively unrepairable without breaking the floor. A Mitsubishi multi-head system gives you both heating and cooling, which the slab never did, and it is the practical path forward. We will walk you through it at the estimate.
