4 Best Heating contractor in Oakland for SameDay Service

Elden Plumbing and Heating, Inc. is a plumbing and heating contractor at 1939 21st Ave in Oakland's San Antonio neighborhood, working across Oakland and Alameda County. As both a plumber and a heating contractor, it covers plumbing services and heating services together: water heater installation and repair, drain work, general plumbing, and emergency services, with permit records showing furnace replacement and sewer lateral replacement projects. The company keeps weekday hours of 7 AM to 6 PM and Saturday hours of 7 AM to 3 PM. Its listings describe both residential and commercial plumbing contracting alongside heating services, and BuildZoom permit records show projects including furnace replacements and sewer lateral replacements. That permit activity suggests a shop accustomed to code-governed, permit-pulled work rather than small repairs alone. The dual plumbing-and-heating identity means heating equipment can be handled by the same contractor that does the plumbing side, without coordinating two trades. This is a fit for Oakland homeowners who want one contractor for both plumbing and heating jobs, particularly water heater replacements and furnace work. The permit history with sewer laterals makes it a practical option for owners of older Oakland properties facing lateral replacement. For anyone weighing contractors on a larger project, the combination of plumbing and HVAC licensing under one roof simplifies the decision.

Renoir Plumbing Inc. is an Oakland plumbing, heating, and contracting company based in the East Lake district at 525 E 11th Street. Its offerings cover residential and commercial plumbing service and repair alongside hydronic heating and solar water heating — a combination that sets it apart from general repair shops. Listed capabilities include whole-house re-copper, sewer camera inspection and snaking, boiler and hydronic system installation and maintenance, solar water heater work, air-to-water heat pumps, and robust fixture and piping solutions for commercial kitchens, bathrooms, and boiler rooms. Weekday hours run 7:00 AM to 4:00 PM. Reviews describe respectful, quiet, efficient technicians; one Berkeley family's assistant noted the crew worked cleanly and would be called again. The company describes its trade around skilled metalwork and long-lasting system solutions rather than quick fixes. It also commits publicly to a living wage, paid vacation and holidays, retirement benefits, and health care for its plumbers — a detail that signals a stable, career-oriented workforce handling home and commercial systems. This is a fit for East Bay homeowners with hydronic or radiant heating, boilers, or solar thermal systems who need a shop that installs and maintains those systems rather than only fixing leaks. Commercial property managers dealing with boiler rooms or kitchen plumbing will find the metal-focused capability relevant. With Saturday closed and weekday daytime hours, it suits planned projects — system replacements, re-pipes, remodel plumbing — rather than middle-of-the-night emergencies.

California Plumbing & Radiant Heating Inc. is a West Oakland plumbing and heating contractor at 2601 Adeline Street, combining general plumbing with a specialist focus on hydronic radiant heating. Its listed offerings include hydronic radiant heating systems, boiler services, HVAC services, general plumbing, and water heater services. Review records show expertise in complex equipment — tankless water heaters, hydronic air heaters, and boilers such as the Lochinvar Knight — the kind of systems that few Bay Area trades service. The review record centers on the owner, Gerald, described as exceptionally knowledgeable about radiant and hydronic systems. Customers describe him spending 45 minutes or more diagnosing a system, running through everything that could be wrong, and in one case flushing the system and honestly advising that nothing needed replacement — declining to charge for the visit. Others credit him with fixing a tankless water heater and radiant system on the first attempt and teaching them how to maintain their own equipment. This is a fit for Bay Area homeowners with hydronic radiant heat or boilers who have struggled to find a technician who understands their system. New homeowners inheriting complex heating setups may value the walk-through approach that explains each component. For anyone wary of upsells, the documented pattern of honest no-charge diagnoses addresses the trust question directly.

Harry Clark Plumbing and Heating Inc is an Oakland plumbing and heating contractor based at 3026 Broadway, covering plumbing, heating, and air conditioning from one shop. Its listed work includes furnace repair and installation, thermostats and zoning, gas line repairs, trenchless sewer repair, toilet repairs, re-piping, drain cleaning, mystery leak repairs, valve pressure issues, and heat pump and air conditioning service including ducted central and ductless mini-split systems. The company serves Oakland and Berkeley. Review themes center on heating expertise and older homes: Don Marshall is named as the heating specialist, Brian is noted for special-ordering an unusual-size water heater and installing it on time, and Jason's crew is praised for inspection work that accommodates tight real estate schedules, with office staff member Daniele noted for responsive communication. Longtime customers describe fair prices and reliable service over many years. The record also carries honest negatives: one detailed review describes a sewer lateral replacement with poor communication and a disputed code issue, and another reports a slow, poorly communicated street restoration job. This company fits Oakland and Berkeley owners of older homes who need both plumbing and heating handled by one long-standing local contractor, including heat pump and furnace work. Weekday hours of 7:30 AM to 4:30 PM with weekends closed point it toward planned projects rather than emergencies. Given the two detailed negative experiences, asking for a clear written scope and timeline before approving larger jobs is prudent.
