How it works

The seven steps a furnace takes to make heat.

A furnace checks itself at every step, and stops if a step fails. Pick a fault to see where the sequence breaks.

Working. The thermostat calls, the inducer fan clears the vent, the igniter glows, gas flows, the sensor proves the flame, and then the blower sends warm air to the rooms.

  1. Starts the sequence by closing a low voltage circuit. Dead batteries stop everything.

  2. Clears the heat exchanger and proves the vent is open before any gas flows.

  3. A small element that glows orange hot. It's fragile and one of the most replaced furnace parts.

  4. Should light together with a steady blue flame. Rust and dust make them light late and loud.

  5. A metal rod in the flame. If it can't sense flame, the gas shuts off in seconds.

  6. Keeps combustion gases apart from the air you breathe. A crack here is the reason to replace a furnace.

  7. Opens only when the board has seen every safety check pass.

  8. Runs the sequence and flashes a code when something fails. Tell us the flash count when you call.

  9. Starts after the exchanger is warm, and keeps running briefly after the burners stop.

  10. Change it every one to three months in the heating season. It protects the blower and the heat exchanger.

What's included

What we do.

Everything here is part of the job, not an extra.

  • Diagnosis first

    We find the cause before anyone talks about replacing the furnace.

  • Igniters, flame sensors and gas valves

    The parts behind most calls for no heat.

  • Blower motors, capacitors and boards

    Tested with a meter, and replaced only when they fail the test.

  • Wall furnaces and floor furnaces

    Common in older Santa Barbara homes and apartments. One of our reviews is a wall furnace another company walked away from.

  • Heat pumps in heating mode

    Including Samsung systems.

  • Gas and CO test

    We test for gas leaks and carbon monoxide before we leave.

From our reviews

In customers' words.

“I urgently needed my heater fixed because it was freezing in my house and I have a baby. This company was awesome -- squeezed me in same day when no one else could. They came in a timely manner and efficiently fixed the issue and our home was warm by the later afternoon. Highly recommend J&Js!”

“J&J did a fabulous job when our furnace went out. They came promptly, were very careful, and cleaned up afterwards. Plus, they are really nice guys!”

“DM'd Jeremy when my furnace wouldn't ignite. We messaged back and forth with troubleshooting tests. Jeremy determined the problem and gave me the part number to order. Installed new part and now my furnace is up and running like new.”

Charles H.
Furnace ignition, on Google

“We had installed a direct vent wall furnace, a direct replacement for one that had died. The pilot on the new furnace would shut off after a day or two. After a brief attempt at repair, the company that hooked it up refused to follow up with the manufacturer and suggested that we replace it with a much more expensive unit. I contacted J&J after a referral from a friend and Jeremy came out to see if he could help. After attempting a couple of things recommended by the manufacturer with no success, he continued to work with the manufacturer on a solution. I might add that he had some poor customer service from the manufacturer in returning his calls, texts and emails, but he stuck with it to final resolution. Thank you Jeremy”

“J&Js was super helpful and professional. Quickly diagnosed and fixed what seemed like a complicated problem. They also tested for leaks and carbon monoxide- which no other repair service that I've used has done. I recommend them very highly.”

“Jeremy and his team were thoughtful, professional and we'll be calling them again when we need them. They are price conscious, problem solvers and very thorough with their work. They also made sure we were up and running with a new heater before the holidays. Very impressed!”

    A garage is quick. An attic or a crawlspace takes longer.

In Santa Barbara County

Furnace and heater repair near you.

Furnaces here sit idle for most of the year, then get switched on during the first cold week of November or December. That first week is when igniters fail and dust burns off, and it's our busiest week for heat.

Valley nights in Santa Ynez, Solvang and Buellton get colder than the coast, and a house without heat cools fast. If there's a baby or an older person at home, say so when you call and we'll tell you honestly how soon we can come.

Where we do this work
Questions

Common questions.

Anything else, call or text me.

Why won't my furnace turn on?

Start with the thermostat batteries, the breaker, the switch near the furnace and the filter. If those are fine, the usual causes are a failed igniter, a dirty flame sensor or a safety switch that has tripped.

How much does furnace repair cost in Santa Barbara?

Our residential diagnostic is $220 and commercial is $250. The repair is quoted flat rate before we start and depends on the part.

Why does my furnace smell when it first comes on?

A dusty smell for the first hour of the season is normal. A gas smell is not: leave the house and call 911 and SoCalGas at 1-800-427-2200.

Is it worth repairing an old furnace?

Usually, if the heat exchanger is sound and the part is available. We'll give you a realistic read, and a replacement number only if it makes sense.

Do you offer emergency furnace repair?

We offer after-hours appointments when a technician is available. Call and we'll tell you the soonest we can come. See after-hours service.

Do you repair wall heaters?

Yes. Wall furnaces and floor furnaces are common in older homes here, and we service them.

How often should a furnace be serviced?

Once a year, before the heating season. A tune up cleans the burners and flame sensor and catches a weak igniter early.
