FAQs

Do you service commercial steam and hydronic heating systems?

Unfortunately, we do not. We only service single family residential homes. We do not service heating systems for apartments, multi-unit buildings, commercial or any other commercial-style heating systems.

Do you service heating systems for condominiums?

It depends. If the boiler and heating system belongs to the individual condominium, then yes. However, if the heating system is connected to the centralized heating system for the entire complex, then unfortunately we will not service that heating system.

Do you test backflow preventers for residential and commercial buildings?

Yes, we do.

Do you provide after hours or emergency services?

Unfortunately, we do not unless it is a heating system that was initially installed by us.

Do you provide service outside of San Francisco?

Unfortunately, we do not work outside of the City and County of San Francisco.
