Heat Pump Not Heating in Newark

Most Newark housing is 1960s through 80s tract construction, and the HVAC has aged right along with it. A lot of the heat pumps here are first conversions off old gas furnaces, or second-generation equipment now 15 to 20 years in. When one stops heating, age matters, because the failed part tells us whether this is a quick repair or the start of a repair-or-replace conversation.

Sometimes a no-heat call is a cheap, fast fix. A capacitor. A contactor. A defrost sensor. Other times it is a refrigerant leak on older equipment, and on systems still running R-22 the economics shift, because reclaimed R-22 is expensive and a leaky system will leak again. We run that math at the estimate so you decide with real numbers, not pressure.

Newark's bay-influenced winters are cool, not harsh. The climate is well inside heat-pump range, so a no-heat call is a fault to diagnose, not the weather defeating the equipment. We find the part, and if the part points to a larger problem on an aging unit, we say so plainly.

Common causes

Run capacitor failure. On a tract-age system, a weak or dead run capacitor is the single most common no-start. The compressor or fan tries and can't spin up, so no heat. It reads low on a meter against its rated microfarads. We carry the common sizes and swap it the same visit.

Refrigerant leak on R-22 equipment. Older Newark systems may still run R-22. A slow leak drops heating capacity, and the fix isn't a simple recharge, because the refrigerant is expensive and the leak will return. We pressure-test, locate the leak, and then walk through repair cost versus a heat-pump replacement honestly, since age and refrigerant type both drive that decision.

Reversing valve or solenoid fault. If the unit runs but blows cool when it should heat, the reversing valve isn't switching into heating. The solenoid coil is often the failure and is a clean replacement; a stuck valve body is a larger repair. We confirm by reading line temperatures before we quote either.

Defrost board or sensor out of spec. Cool, damp Newark mornings frost the outdoor coil. A failed defrost control or sensor lets ice build until heating output drops off. We observe a defrost cycle and check sensor resistance, then replace whatever is reading wrong.

Pitted or stuck contactor. The contactor is the relay that powers the outdoor unit. After years of cycling, the contacts pit and stop making clean connection, so the unit won't start or starts intermittently. It's a low-cost wear part we replace on the spot.

How we diagnose it

Check the thermostat call and watch whether the outdoor unit starts, hums, or stays silent.
Meter the run capacitor and inspect the contactor for pitting on any no-start complaint.
Identify the refrigerant type, then pressure-test and check the charge to find leaks, R-22 changes the conversation.
Read line temperatures to confirm whether the reversing valve is actually switching into heating.
Run and observe a defrost cycle, checking the board and sensor against spec.

$75 diagnostic, credited toward any repair over $200. You get a written quote before any work begins.

Heat Pump Not Heating in Newark: common questions

How fast can you get to Newark?

We run Newark, Fremont, and Union City regularly out of our San Ramon base. No-heat calls get bumped up the schedule, and we aim for same-day when the route allows, though that's a best effort, not a promise. Call (925) 999-4095 for a real time window.

My heat pump is old and it stopped heating. Repair or replace?

That depends on the part that failed, the system age, and the refrigerant. A capacitor on a 12-year-old unit is an easy repair. A refrigerant leak on R-22 usually tips toward replacement, because the refrigerant is expensive and the leak returns. We put both numbers on the estimate and let you choose.

Is the cool Newark winter too much for a heat pump?

Not at all. Newark winters are mild and well within where a heat pump runs at full capacity. If yours quit heating, something failed inside it. The climate isn't the issue here.
