About Kelly Plumbing & Heating
Kelly Plumbing & Heating operates as an HVAC contractor serving Marin County and Sonoma County from a base in Novato, California. The company holds a 4.9-star rating compiled from 329 customer reviews, placing it among the highest-rated contractors in the North Bay region. Their service menu covers the full spectrum of residential climate control, including furnace repair and replacement, tankless and traditional water heaters, heat pumps, ductless mini-splits, and air quality solutions. The business also handles plumbing services ranging from water heater installations to leak repairs and diagnostic work. Operating hours run Monday through Friday from 8 AM to 5 PM, with Saturday and Sunday closed.
The company distinguishes itself through several concrete offerings visible on their website. They maintain partnerships with major equipment manufacturers including Trane, Mitsubishi, Daikin, Fujitsu, and Bosch, allowing them to recommend systems matched to each homeowner's specific needs and budget. Their annual maintenance program provides scheduled service agreements that keep heating and cooling systems operating at peak efficiency throughout the year. The business offers financing options through third-party lenders, making larger equipment replacements more accessible to homeowners who prefer installment payments over upfront costs. They also advertise an exclusive warranty on workmanship, providing documented coverage that extends beyond typical contractor guarantees.
Customer reviews name two service technicians who consistently receive commendations. Ryan Bishop handled both an annual HVAC inspection and a follow-up plumbing repair for one reviewer, with the customer noting his diagnostic skill resolved a plumbing issue quickly and at reasonable cost. DJ performed furnace annual maintenance and water heater service for multiple reviewers, with one customer specifically mentioning his thorough explanation of how a new Trane heat pump system operates differently from conventional heating equipment. Another reviewer described a same-day emergency call during a cold spell where the team squeezed them into the schedule despite full capacity, repairing a furnace that other contractors had declined to service. These scenarios demonstrate the contractor's willingness to respond to time-sensitive customer needs.
