Why Homeowners Choose John Owens

  • Family-run and locally rooted since 1986, with a 4.9-star Google rating and happy customers from Marin and Sonoma homeowners
  • Fully licensed (CA #501853) multi-trade crew, so the HVAC, electrical, and plumbing-side work on your install is handled by one team, not three subs
  • Local heat-pump service across Marin and Sonoma, with availability and appointment windows confirmed by our office
  • Real Manual-J load sizing, so your system is matched to your actual home, not a guess that leaves canyon rooms cold or hillside additions sweltering
  • Ductless mini-split specialists for the many older local homes with floor furnaces, radiant heat, or no ductwork at all, including ADUs and converted attics
  • Straight guidance on rebates and PG&E rate impact, so the electrification math actually makes sense before you commit

Heat Pump Repair, Installation & Replacement

  • One system, two seasons: a heat pump heats your home in our cool, damp winters and cools it through hot inland Sonoma summers, replacing both furnace and AC
  • Ductless mini-splits add zoned comfort to rooms with no ductwork, common in older Marin cottages, additions, and ADUs, without tearing open walls
  • Heat pumps run efficiently in our mild coastal climate, where temperatures rarely drop near freezing, and typically cut heating energy use versus an old gas furnace
  • All-electric operation pairs well with solar and qualifies for local rebates, helping offset PG&E costs and move you off natural gas
  • Sealed, filtered heat-pump systems improve indoor air during wildfire-smoke season, a real benefit for homes from Novato to Sebastopol
  • The system blows lukewarm air
  • Rooms heat or cool unevenly
  • The heat pump runs constantly or short cycles
  • Outdoor unit icing or unusual noise
  • Energy bills jump without a clear reason
  • Thermostat changes do not improve comfort
  • An old furnace or air conditioner is unreliable and repair costs are rising
  • You want efficient electric heating and cooling from one system

Frequently Asked Questions

How much does heat pump installation cost in Marin and Sonoma County?

Cost depends on your home’s size, ductwork, and electrical, so we provide a firm quote after a load calculation and site visit. We also walk you through BayREN, TECH, and PG&E rebates that often take a meaningful bite out of an all-electric heat pump installation here.

How do I schedule heat pump repair?

Request service online or call during office hours, Monday through Friday from 7:30am to 5:30pm. Our office will confirm availability and your appointment window.

Is a ductless mini split a good fit for an older home or ADU?

Often yes. Ductless mini-splits are ideal for the many older Marin and Sonoma homes with floor furnaces, radiant heat, or no ducts, and they add efficient, room-by-room comfort to additions and ADUs without major remodeling.

Do heat pumps work well in Marin and Sonoma’s climate?

Very well. Our mild, rarely-freezing coastal winters are close to ideal for heat pumps, and a single system handles both winter heating and the hotter summers now common inland in Petaluma, Sonoma, and Rohnert Park.

Do you repair both ducted and ductless heat pumps?

Yes. We service heat pump systems, ductless mini-splits, and related airflow or control issues for Marin and Sonoma County homes.

When should a heat pump be replaced instead of repaired?

Replacement may make sense when the equipment is aging, inefficient, unreliable, or facing a major repair. We explain repair and replacement options clearly.

Can poor airflow make a heat pump seem broken?

Yes. Duct restrictions, dirty filters, blocked returns, or airflow imbalance can reduce performance, so diagnosis should include the whole system.

Can a heat pump replace my furnace and air conditioner?

In many homes, yes. The right answer depends on the house, comfort goals, ductwork, and electrical setup.

Will you review my existing ductwork?

Yes. Duct condition and airflow matter for comfort, efficiency, and equipment performance.
