The short answer
AllPro HVAC Services repairs gas furnaces, heat pumps and wall heaters in Alhambra (91801, 91803), with 24/7 emergency service. We find the actual cause, explain your options, and tell you plainly whether a repair makes sense or whether replacement rules and rebates are worth looking at first.
Alhambra winters are mild, so a furnace or heat pump can sit unused for months and then get asked to work hard on the first cold night. That's usually when problems show up: a burner that won't light, a blower pushing cold air, or a thermostat that stops responding. AllPro HVAC Services repairs gas furnaces, heat pumps and wall heaters in homes across Alhambra's 91801 and 91803 ZIP codes. We're based about 5 miles west in Los Angeles, and we offer 24/7 emergency service when the heat goes out.
Heating Problems We See in Alhambra Homes
Because Los Angeles has a Mediterranean climate with mild winters, heating systems here often run in short bursts for a few weeks a year. Long idle stretches let dust settle on burners and sensors, let batteries in thermostats die, and hide small problems until the first chilly evening. When you call, describe what you're noticing. Details like sounds, smells and when the problem started help us narrow things down before we arrive.
- Furnace won't ignite, or lights and then shuts off after a few seconds
- Blower runs but the air from the vents is cool or lukewarm
- Burning-dust smell that doesn't fade after the first few minutes of use
- Heat pump stuck in defrost, short cycling, or blowing cold air in heat mode
- Thermostat blank, unresponsive, or not calling for heat
- Loud banging, squealing or rattling from the furnace cabinet
- Wall heater that won't stay lit or heats unevenly
What a Heating Repair Visit Looks Like
We start with the basics that cause a surprising number of no-heat calls: thermostat settings and power, the breaker and furnace switch, and the air filter. A badly clogged filter can make a furnace overheat and shut itself off as a safety measure.
From there, the technician checks the parts that match your symptoms. On a gas furnace, that can mean the igniter, flame sensor, gas valve, pressure switch, inducer motor, blower and limit switches. On a heat pump, we look at refrigerant-side performance, the reversing valve, the defrost controls and the outdoor unit. If we find signs of a cracked heat exchanger or a gas or carbon monoxide concern, we'll explain what we found and shut the system down rather than leave it running unsafely.
Before any work begins, we tell you what failed, what the fix involves, and what other options you have.
Repair or Replace? A Note on Furnace Rules
Most heating calls end with a repair. A worn igniter or dirty flame sensor doesn't mean you need a new system. Replacement is worth discussing when a furnace has a damaged heat exchanger, needs repeated major part replacements, or simply can't keep the house comfortable anymore.
If you're weighing a new gas furnace, know that South Coast AQMD Rule 1111 limits NOx emissions from natural-gas fan-type central furnaces sold and installed in the Los Angeles region, and the district has been amending the rule toward zero-emission requirements. The district sets and revises the compliance dates, so check the current version of the rule before you decide. We'll walk you through how it may affect your choices, including whether a heat pump is worth considering.
Heat Pumps and Rebates in Alhambra
Many homes outside the City of Los Angeles, including in cities like Alhambra, are served by Southern California Edison rather than LADWP. That matters because the equipment rebates available to you depend on the utility that serves your address. We confirm the current offer for your home before we bring it into a quote.
For homes that are LADWP residential electric customers, the Consumer Rebate Program offers rebates on qualifying heat pump HVAC systems, with the amount based on the unit's SEER2 and HSPF2 ratings. You file that application after the equipment is purchased and installed, within 12 months of purchase.
One change to be aware of: the federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations after that date, so don't count on it when budgeting a new system.
Keeping Your Heat Ready Between Cold Snaps
A few simple habits make a difference in a mild climate. Run your heat briefly in the fall, before you actually need it, so problems show up on your schedule instead of on a cold night. Replace the air filter, keep the area around the furnace clear of stored items, and make sure supply and return vents aren't blocked by furniture or rugs. If you have a heat pump, keep leaves and debris away from the outdoor unit. Fall Santa Ana winds can blow a lot of debris against it.
If something still goes wrong, we serve Alhambra along with nearby South Pasadena, San Gabriel, Monterey Park, San Marino and Pasadena, and we offer 24/7 emergency service.
