Why is Burbank good heat-pump country?
A heat pump is just an air conditioner that can run backwards to heat, and it earns its keep where winters are mild - which describes Burbank's Climate Zone 9 perfectly. You rarely see the deep cold that forces a heat pump into inefficient backup heat, so a Carrier 27-series unit covers almost all your annual heating with electricity. Pair that with strong summer cooling demand on the valley floor, and one variable-speed Greenspeed system (27VNA3) handles both seasons quietly and efficiently.
| Symptom | Likely cause / first check | Cost lane |
|---|---|---|
| Cold air in heat mode (continuous) | Stuck reversing valve or solenoid | $400-$1,500 |
| Outdoor unit iced, weak heat | Defrost control or sensor fault | $250-$900 |
| Hums, won't start | Capacitor or contactor | $150-$450 |
| Runs single-speed (27VNA3) | Comm fault, code 178/179 | $200-$2,000 |
| Gas-to-heat-pump conversion | Full install + electrical + Title-24 | $6,000-$16,000 |
Which Carrier heat pumps do you service, and what fits which home?
The 27-series spans value to flagship, and the right tier depends on the home and the budget:
- 27SCA5 (Comfort 16): single-stage value heat pump for a budget-led gas-to-electric swap on a small cottage.
- 27SPA6 (Performance 16) and 27TPA8 (Performance 18): single- and two-stage mid-tier; the two-stage adds quieter operation and steadier temperatures in a leaky pre-war home.
- 27VPA9 (Performance 19): variable-speed InteliSense - most of the Greenspeed benefit at a lower price.
- 27VNA3 (Infinity 23) and 25VNA4 (Infinity 24): Greenspeed flagships, up to ~22 SEER2 and ~10.5 HSPF2 on the 25VNA4, for larger or two-story homes that benefit from long, low-speed runs.
- 37MURA / 37MUHA crossover mini-split heat pumps: compact ducted inverter units for a slab or shallow-attic cottage with no room for a conventional air handler.
The Greenspeed units (27VNA3, 25VNA4) require the Infinity System Control to modulate; the Performance and Comfort units run on conventional or Cor controls.
What faults are specific to a Carrier heat pump?
A heat pump adds the reversing valve and the defrost cycle, so it has heating-mode failures a cooling-only condenser never sees:
| Symptom | Likely cause | Component |
|---|---|---|
| Cold air in heat mode (continuous) | Stuck reversing valve or dead solenoid | Reversing valve, solenoid coil |
| Brief cool air every hour or two | Normal defrost cycle (not a fault) | Defrost control (verify timing only) |
| Outdoor coil iced, weak heat | Defrost board or sensor fault | Defrost control board, coil thermistor |
| Hums, won't start | Capacitor or contactor | Dual-run capacitor, contactor |
| 27VNA3 runs single-speed | Communication fault | Infinity control, ABCD wiring (178/179) |
Everything else - capacitor, contactor, compressor, and on Greenspeed units the inverter board and 178/179 comm faults - mirrors the AC side, so a tech who knows the cooling pattern adds only the valve and defrost logic for heating.
What does a gas-to-heat-pump conversion take in Burbank?
An electrification job is more than swapping a box. We pull the gas furnace and AC, set in a Carrier heat pump system sized off a Manual J load, and handle the parts that trip up a drop-in: the electrical service in an older home often needs a verified 240V circuit and adequate panel capacity for the heat pump and any backup heat strip; the line-set may need re-routing on a hillside rebuild with a long run; and a slab or shallow-attic cottage may push the decision toward a 37M crossover mini-split instead of a conventional air handler. The conversion triggers Title-24 refrigerant-charge and airflow verification, plus duct-leakage testing where ductwork is altered, and we document it to pass. Burbank's mild Climate Zone 9 winter is what makes the heat pump cover nearly all annual heating without leaning on inefficient backup.
How do you diagnose a heat-pump heating complaint?
A no-heat or weak-heat call on a heat pump runs differently from a no-cool call, because we have to verify the reversing valve and defrost logic before touching the sealed system. The sequence:
- Confirm the mode change. Energize the O/B reversing-valve circuit from the thermostat and listen for the valve to shift; a valve that never clicks over points to a dead solenoid coil (measure it for an open winding) or a stuck spool.
- Read both coil temperatures. In heating, the outdoor coil should run colder than ambient and the indoor coil warm; if they are backwards or equal, the valve is not transferring or the charge is low.
- Verify the defrost cycle. Force a defrost and time it - a board that never initiates, or terminates too early, lets the outdoor coil ice over and choke heat. Check the coil thermistor against its resistance table.
- Check charge by superheat and subcooling. A heat pump low on refrigerant heats weakly long before it cools weakly, so we gauge it against the heating-mode nameplate targets, not the cooling ones.
On a Greenspeed 27VNA3 or 25VNA4, the Infinity touchscreen logs the heating-side faults too, so we pull stored 178/179 comm codes and any inverter alert before opening a panel - the same code-first discipline we use on the cooling side.
What should I know about rebates and the expired tax credit?
Here is the straight version for a 2026 Burbank install. Congress repealed the federal Section 25C tax credit - the 30 percent break worth up to $2,000 on a heat pump - as of December 31, 2025, so it covers no new install this year; do not let a quote lean on it. Utility incentives can still pitch in, and here the utility is usually the municipal Burbank Water and Power, not LADWP or SCE - BWP has run its own heat-pump and electrification rebates, with SoCalGas incentives on the gas-appliance side. These programs move in phases and a number of statewide funds were reported booked out in early 2026, so we help you nail down the live amounts and status before you sign. Our SEER2 and rebates guide digs in further.
Common questions
Does a heat pump make sense in Burbank's mild winters?
It is close to ideal here. Burbank winters rarely drop near the temperatures where a heat pump struggles, so a Carrier 27-series unit covers nearly all your heating with electricity instead of gas - and it is the same box that cools you in summer. The mild Climate Zone 9 winter is exactly why heat pumps pencil out better here than in cold climates.
My heat pump blows cold air in heating mode - is it broken?
Not necessarily. During a defrost cycle the unit briefly reverses to melt frost off the outdoor coil, and the indoor air can feel cool for a few minutes - that is normal. If it blows cold continuously in heat mode, suspect a stuck reversing valve, a failed reversing-valve solenoid, low charge, or a defrost-control fault. We test the valve and charge to pin it down.
Can you convert my gas furnace to a Carrier heat pump?
Yes, and it is a rising slice of what we do in Burbank. We pull the gas furnace and AC, set in a Carrier heat pump system, size it off a Manual J load, take care of the electrical and Title-24 paperwork, and look into whether a Burbank Water and Power electrification rebate fits your case. Keep in mind the federal 25C tax credit lapsed on December 31, 2025, so do not pencil it into a 2026 install.
What heat pump rebates can I actually get in Burbank?
It hinges on your utility, and most of Burbank is served by the municipal Burbank Water and Power rather than LADWP or SCE. BWP has run its own heat-pump and electrification incentives, with dollar figures that cycle through funding phases, and a few statewide funds were reported booked out early in 2026. We help you confirm where each program stands before you count on a single dollar.
