No Heat from Your Furnace or Heat Pump in Encino
First, the answer: When an Encino home loses heat, call Encino Mitsubishi HVAC at (213) 805-8137 or book online: we separate a gas-furnace lockout (igniter, flame sensor, pressure switch) from a Mitsubishi heat-pump fault (reversing valve, defrost, or inverter) across ZIP codes 91316 and 91436. Read the control-board LED flash code first if you can do so safely.
The short list
- Furnace lockouts: hot-surface igniter, flame sensor, pressure switch, high-limit, gas valve.
- Furnace boards flash LED codes; a rollout code can flag a cracked heat exchanger - shut it down.
- Heat-pump no-heat: reversing valve, solenoid coil, defrost control, or control board.
- Reversing-valve and sealed-system repairs: roughly $300-$1,200; inverter board $400-$2,000.
- Encino winters are mild, so no-heat is rarely life-safety - except combustion or gas smell.
- Diagnostic $129-$200; we work both gas furnaces and Mitsubishi heat pumps.
Is it the furnace or the heat pump?
Encino homes split between gas furnaces (often paired with a separate AC condenser) and Mitsubishi heat pumps that heat and cool from one system. The diagnosis differs. A gas furnace that will not heat has usually locked out on an ignition or safety fault, and its control board flashes an LED code. A Mitsubishi heat pump that cools but will not heat points at the reversing valve and its controls. The table sorts the symptoms.
| Symptom | Likely cause / first check | Cost lane |
|---|---|---|
| Furnace clicks, will not light | Hot-surface igniter or flame sensor | $150 - $500 |
| Furnace starts, dies after a minute | Dirty flame sensor or high-limit trip (low airflow) | $150 - $450 |
| Furnace will not start, vent code | Pressure switch or inducer motor | $200 - $700 |
| Heat pump cools but will not heat | Reversing valve, solenoid coil, or board | $300 - $1,200 |
| Heat pump ices, weak heat | Defrost control or low refrigerant - U7 / P8 | $225 - $1,500 |
How do you read a furnace flash code?
Most modern gas-furnace control boards report faults by blinking a status LED visible through a sight glass on the burner door. Count the flashes: patterns commonly map to a system lockout, a pressure-switch error, an open high-limit from low airflow, an ignition-proving failure, or a weak flame-sense signal. A rollout-switch code deserves special caution because it can indicate an overheated or cracked heat exchanger - a combustion-safety issue. If you can read the flash count, tell us the number so we arrive with the right part in hand.
When is a no-heat call urgent in Encino?
Because the valley's winters are mild, a dead furnace overnight is uncomfortable but rarely dangerous here. The real urgency is combustion safety: if you smell gas, shut the gas off and call the utility; if the furnace flags a rollout switch or you see soot or scorching, stop running it and call us before restarting. For a Mitsubishi heat pump, no-heat is purely a comfort and component issue, and we cover those faults in depth on the heat pump repair page.
What are the safe checks versus the call-a-pro line?
A few checks are safe for any homeowner, and a clear line separates them from work that needs a tech and a meter. Safe to do yourself: confirm the thermostat is set to heat above room temperature, replace a clogged filter, reset a tripped breaker once, and read the furnace control-board LED flash count through the sight glass. Stop and call a pro the moment you smell gas, see a rollout-switch code, find soot or scorching at the burners, or face anything inside the sealed refrigerant circuit on a heat pump. Opening a gas valve, jumpering a safety switch, or refilling refrigerant are not homeowner tasks - a defeated rollout or limit switch exists precisely to stop a cracked heat exchanger from venting combustion byproducts into the house. On a Mitsubishi heat pump, a reversing-valve or inverter fault needs the controller code and pressure readings to confirm, not a parts swap.
What does a no-heat repair cost in Encino?
The diagnostic visit runs about $129 to $200 and is often credited toward an approved repair. From there the common gas-furnace fixes are modest: a hot-surface igniter or flame-sensor cleaning and replacement lands around $150 to $500, a pressure switch or inducer motor around $200 to $700, and a gas valve toward the upper end of that range. On a Mitsubishi heat pump, a reversing valve or its solenoid coil runs roughly $300 to $1,200, while an inverter or control board sits at $400 to $2,000 and a sealed-system leak repair with recharge falls between $225 and $1,500. A suspected cracked heat exchanger is the one finding that usually tips a furnace toward replacement rather than repair, and we will show you the evidence before recommending it. Where a Mitsubishi unit is still under parts-and-labor warranty, covered work should go to an authorized dealer first.
No-heat questions from Encino owners
My gas furnace clicks but will not light - why?
A furnace that clicks but does not light has usually locked out on an ignition or safety fault: a worn hot-surface igniter, a dirty flame sensor, or a pressure-switch/inducer issue. Many furnace control boards flash a code through an LED - count the flashes and tell us the number so we arrive with the right part.
My Mitsubishi heat pump cools but no longer heats. What gives?
That split points at the reversing valve, its solenoid coil, or the board that energizes the valve, since heating and cooling share one refrigerant circuit. A stuck defrost cycle can also mimic no heat. We confirm the valve actually shifts on a heat call before condemning any part.
Is no heat ever an emergency in mild Encino?
Encino winters are gentle, so a no-heat call is rarely life-safety here. The exception is anything involving combustion: if you smell gas, or a furnace shows a rollout-switch code (a possible cracked heat exchanger), shut it down and call right away rather than restarting it.
Why does my furnace start then shut off after a minute?
That short heat cycle usually means the flame is lighting but a safety is dropping it - a dirty flame sensor that loses the flame signal, or a high-limit trip from low airflow on a clogged filter. The board often logs it as an ignition-proving or limit fault.
Do you work on both gas furnaces and Mitsubishi heat pumps?
Yes. Many Encino homes pair a gas furnace with a separate condenser, so we diagnose furnace lockouts as well as Mitsubishi heat-pump heating faults, and we can lay out a conversion if you want to drop the gas appliance entirely.
