In Santa Rosa, furnace repair is our most requested heating call, followed by replacement and installation. Our Santa Rosa office sends licensed technicians to find the cause on every heating repair and heater repair call, whether the furnace has stopped heating, started short cycling or smells wrong.

We keep the decision simple. Repair comes first when the furnace is serviceable. Replacement is for cracked heat exchangers, unsafe venting, repeated failures, or equipment that no longer makes sense to maintain. When it comes to that, you get a free estimate, financing options, and help from our in-house rebate department with qualifying utility programs.

We also service furnaces on a yearly schedule, which is the first step of the John Owens Way: maintain first, repair when needed, replace last. John Owens Services is family-owned, has been in business since 1986, and is licensed and insured in California, license #501853. Call the Santa Rosa office to schedule furnace repair, maintenance or a replacement visit. Same-day service available across Santa Rosa. Call us now. We also handle new furnace installation in Santa Rosa when a replacement makes more sense than another repair.

Frequently Asked Questions

Who does furnace repair in Santa Rosa?

We do, from our Santa Rosa office. A licensed technician diagnoses the furnace and tells you what is wrong. We repair it when repair makes sense. Same-day service available across Santa Rosa. Call us to schedule a visit.

What does furnace replacement in Santa Rosa, CA involve?

It starts with a free estimate. We look at your home and heating needs, recommend a furnace that fits, and go over financing and qualifying utility rebates. We replace last, so we tell you honestly if repair is the better path for your system.

Should I repair or replace my old furnace?

It depends on how often the furnace has needed repairs, its condition and your home’s heating needs. We inspect it, explain what we found and let you decide. A cracked heat exchanger or unsafe venting points toward replacement. A single worn part usually does not.

How often should I have my furnace maintained?

Once a year. Maintenance covers the gas, safety, ignition and heat exchanger checks, cleaning the burners and blower, a new air filter, electrical and thermostat testing, and a full cycle test. It helps you avoid strange noises and high utility bills.

Why does my furnace take so long to heat my house?

A clogged filter, a blocked vent or leaking ducts are the usual causes. Leaks let heated air escape into spaces like the attic, so the furnace runs longer to catch up. Call us if the problem continues and we will check the system.
