Your Local HVAC Contractor in San Marino, CA

San Marino homes are large, well-built and often close to a century old, and they ask more of an HVAC system than most: multiple stories, many rooms, long duct runs, guest quarters and expectations of quiet, even comfort throughout. We design, repair and replace systems that meet that standard.

We provide AC repair and installation, furnace repair and replacement, heat pump installation, zoning and multi-system design, ductless mini-splits, duct work and air quality service throughout 91108, from the streets around Lacy Park and the Huntington to the Huntington Drive and San Gabriel Boulevard corridors.

We are based in Glendale and serve San Marino along with Pasadena, South Pasadena and Altadena.

San Marino Homes We Work On

San Marino is almost entirely single-family homes on large lots: 1920s and 1930s Spanish Colonial, Tudor and Monterey Revival houses, mid-century estates and substantial newer rebuilds. Most have two or more HVAC systems, and many have been added onto over the decades, leaving mismatched equipment and duct systems. Zoning, variable-speed equipment and separate systems for guest houses and pool houses are typical of the work we do here.

What Makes San Marino HVAC Different

Local conditions decide what equipment belongs in your home. Here is what we design around in San Marino.

Multiple systems serving one large home

Two, three or four systems installed at different times rarely work well together. We evaluate the whole house, balance and zone what can be kept, and replace what cannot with equipment that matches the load of each area.

Noise and appearance

Homeowners here expect equipment to be quiet and out of sight. We specify low-sound-rated condensers, plan placement away from bedrooms and neighbors, and route line sets and ducts to stay hidden.

Historic construction and finishes

Plaster walls, hardwood and original millwork mean duct work and equipment changes have to be planned carefully. We route through attics, closets and existing chases wherever possible.

San Marino HVAC Questions, Answered

Common questions from San Marino homeowners and property managers.

Can you service a home with several HVAC systems?

Yes. Multi-system homes are typical in San Marino. We can maintain and repair each unit and, when replacing, design the systems to work together with zoning rather than as separate afterthoughts.

How do you keep new equipment quiet and hidden?

We choose low-sound condensers, place them away from bedrooms and property lines where possible, and route ducts and refrigerant lines through attics, closets and existing chases so finished spaces are not disturbed.

Do you handle City of San Marino permits?

Yes. We pull the required mechanical permits for equipment replacement and new installations and schedule inspections.

How quickly can you respond?

We are based in nearby Glendale. Same-day service is available for most repairs during business hours, subject to availability.

Are you licensed and insured?

Yes. NorthernWindHVAC is licensed, bonded and insured under CA License #1149962.
