Dalton Heating & Air Long Beach provides independent Lennox service in Long Beach, including HVAC repair, maintenance, and installation across the city, from the salt-fogged streets of Belmont Shore to the hotter inland stretches of Bixby Knolls. Our techs work on Lennox equipment every week, and we’ve learned the failure patterns these systems develop in coastal air. We are not a Lennox-authorized dealer or factory affiliate. We’re an independent shop that knows Lennox units inside and out, and we put every price in writing before we start. Call (562) 512-7423 for service.
Lennox builds some of the most efficient residential heating and cooling equipment sold in Southern California. The brand’s variable-capacity heat pumps and high-efficiency furnaces are popular in Long Beach because they handle the city’s odd microclimates well. But efficiency comes with complexity, and complexity means the tech standing in front of your unit better know what generation of control board, inverter, or inducer motor you have. We do.
Why Trust Dalton Heating & Air Long Beach for Your Lennox HVAC?
Marco Benitez, owner of Dalton Heating & Air Long Beach, grew up in East Los Angeles and learned his trade fundamentals at Los Angeles Trade-Technical College before spending the better part of two decades turning wrenches on residential and light-commercial systems across Southern California. His crew has run Lennox repair in Huntington Beach and Long Beach for years, including a stretch of older Craftsman homes near Bluff Park where aging condensers and outdated ductwork keep the schedule full. Marco reads a system the way a mechanic reads an engine: methodically, without guessing, and with a written price on the table before any work starts.
Lennox systems are not all the same. A G26 furnace from the 1990s shares a brand name with an EL296V from the last decade, but the control logic, motor type, and failure points are completely different. Our technicians know which generation of Lennox equipment you have by the model number on the data plate, and we diagnose accordingly. We stock common Lennox electrical boards, capacitors, and gas valves on our trucks so many repairs get done in one visit. We also service every repair with a written guarantee for a full year, and if the repair fails in that time, we return at no charge. That’s The Garrison Standard, and it applies to every Lennox job we take.
Styles & brands we work with
Common Lennox HVAC Problems We Fix in Long Beach
- XC25 and XP25 communication errors (codes 292, 435, and others). Lennox’s variable-capacity inverter systems talk to the thermostat using a proprietary signal. When a wiring harness loosens, a firmware update is missed, or a low-voltage connection corrodes, the system throws a communication code. We’ve seen other companies quote $4,500 compressor replacements for what was actually a loose connector at the outdoor control board. We diagnose the fault properly before recommending any part swap.
- ECM blower motor failure in EL296V and SLP98V furnaces. These variable-speed motors typically last eight to ten years before bearings wear and they start humming loud, then shut down. Some companies replace the entire motor module at full OEM price. We check the motor module and the control separately, since sometimes only one side is bad.
- Clogged condensate traps and cracked collector boxes on G26 and G61 furnaces. These legacy models run for decades, but their plastic drain traps and collector boxes degrade over time. A clogged trap or a hairline crack causes intermittent flame rollout and lockout, where the burners fire, then shut off, repeatedly. We clean or replace these parts and test combustion safety before we leave.
- Pin-hole leaks in mid-2010s aluminum evaporator coils (13ACX and 14ACX). Lennox switched to all-aluminum coils around 2015, and the early runs developed leaks around the return bends. A pin-hole leak bleeds refrigerant slowly, so the system still cools but loses capacity over weeks. Patching aluminum coils is usually a short-term fix; we’ll give you an honest quote for replacement when it’s the right call.
- Corroded condenser fins on coastal units. Within two miles of the ocean, salt fog eats outdoor condenser fins faster than anywhere else in Long Beach. We see XC25 and 13ACX units in Belmont Shore and Naples that lose significant efficiency after just five or six years near the water. Rinsing coils annually slows the corrosion, but once fins are brittle and crumbling, the coil needs replacement.
Lennox Parts & Our Repair-vs-Replace Approach
Lennox uses proprietary communication protocols on many of its variable-capacity and modulating systems. That’s why we use Lennox OEM electrical boards, motors, and gas valves whenever those parts fail. Aftermarket equivalents for communication-dependent parts often cause more problems than they solve. But for mechanical wear items like capacitors, contactors, and drain traps, we frequently install quality aftermarket parts that meet or exceed OEM specs at a lower cost. We’ll tell you which part we’re installing and why.
The repair-vs-replace conversation comes down to math. If your Lennox air conditioner is over 12 years old and the compressor has failed, a new mid-range Lennox unit usually costs less long-term than patching an aging system repeatedly. We’ll lay out both numbers in writing so you can decide based on facts, not sales pressure. Call (562) 512-7423 if you want a straight answer on your specific unit.
Our Lennox Service Process – Step by Step
- 1
Listen and diagnose. You tell us exactly what the system is doing, and our tech runs through the diagnostic checklist for your specific Lennox model generation. We check error codes, measure refrigerant pressures, test electrical components, and inspect airflow. The diagnostic fee is quoted before we arrive.
- 2
Written price before any work starts. Once we know what’s wrong, you get a written price for the repair or replacement. No verbal estimates that shift at the door. The price on the paper is the price you pay.
- 3
Repair or install. We use the right parts for your Lennox system, whether that’s an OEM inverter board or an aftermarket capacitor. We install cleanly, torque connections properly, and update firmware when the system calls for it.
- 4
Test under load. We run the system through a full cycle before we leave. For furnaces, that means checking temperature rise, gas pressure, and safety switches. For heat pumps, we verify defrost operation and temperature differentials.
- 5
Written guarantee. Every repair comes with a written one-year guarantee. If the same problem comes back within 365 days, we return at no charge under our 365-Day Done Right Promise.

AfterLennox Products We Service & Install in Long Beach
We service the full range of Lennox residential equipment found in Long Beach homes. That includes the variable-capacity XC25 and XP25 heat pump series, the XC21 and XP21 two-stage systems, EL296V and EL195V high-efficiency furnaces, SLP98V modulating furnaces, and the older G26, G61, and G71 legacy furnace lines. On the cooling side, we work on 13ACX and 14ACX air conditioners regularly, plus Lennox mini-split systems and air handlers paired with any of these. Our trucks carry common Lennox capacitors, contactors, ignitors, flame sensors, and drain traps so many basic repairs don’t require a parts run.

Along with Lennox, we repair and install Carrier, Trane, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. If you have mixed-brand systems in different parts of the house, one call covers all of it.
FAQs – Lennox HVAC Service in Long Beach
Code 292 on an XC25 means the outdoor unit lost communication with the indoor unit or thermostat. The system may still run intermittently because the inverter is rebooting and re-establishing the signal. The usual causes are a loose low-voltage connection, a corroded terminal, or outdated firmware. We check the wiring harness at the control board first, reseat connectors, and update firmware if needed. Call (562) 512-7423 to have it diagnosed before the intermittent fault becomes a full shutdown.
Three flashes on a G26 control board usually means the pressure switch failed to close, not a bad heat exchanger. The most common causes are a clogged condensate trap, a cracked collector box, or a blocked exhaust vent. Our techs clean the trap, check the collector box for cracks, and verify venting before touching anything else. A real heat exchanger failure shows different symptoms like flame roll-out or carbon monoxide readings, which we test for on every furnace repair.
Yes, a capacitor is a $20 to $60 part that takes about 30 minutes to replace. If the capacitor is swollen, leaking, or out of spec on a meter, we replace it with a quality OEM-equivalent part and the system usually runs fine again. A capacitor failure alone does not mean you need a new air conditioner. We’ll only recommend replacement if there’s a deeper problem like a failing compressor or a refrigerant leak. Call (562) 512-7423 for an honest assessment.
No. The ECM blower motor in an EL296V is variable-speed, so it does ramp up and down depending on the call for heat, but a loud hum or rattle that gets worse over time means the motor bearings or the control module are failing. These motors typically last eight to ten years. We test the motor module and the control board separately, since replacing only the bad half costs less than a full motor assembly.
In Long Beach and nearby areas like Garden Grove Lennox service calls, winter icing on a heat pump is usually a defrost control or thermistor problem, not a refrigerant issue. The mild coastal climate means the system doesn’t run as hard as it does in colder regions, so when the outdoor coil ices and the unit doesn’t enter defrost, a bad defrost sensor or control board is the likely culprit. We also see icing when the outdoor coil is clogged with salt and debris from coastal air. A thorough cleaning and a defrost cycle test usually locates the problem fast.

These are written-price ranges, not estimates that shift after the work is done. The exact cost depends on the part that failed and the model you own. Call (562) 512-7423 for a free estimate on your specific Lennox unit.
No. We are an independent Lennox service provider, not an authorized dealer or factory affiliate. That independence means we recommend repairs and replacements based on what’s actually wrong with your system, not on any factory quota or dealership agreement. We use Lennox OEM parts when they’re the right call and quality aftermarket parts when they’ll do the job better for less.
For communication-dependent components like inverter boards, ECM motors, and gas valves, we use Lennox OEM parts because the proprietary protocols don’t always play well with aftermarket replacements. For mechanical items like capacitors, contactors, and drain traps, we often install high-quality aftermarket equivalents that match or exceed OEM specs at a lower price. We’ll tell you which part you’re getting and why before we install it.
Most Lennox repairs are done in a single visit lasting one to two hours, assuming we have the needed part on the truck. More complex jobs like evaporator coil replacements or inverter board swaps can take a few hours. We’ll give you a time window when you book and a realistic completion estimate once we diagnose the unit.
We service XC25, XP25, XC21, and XP21 heat pumps and air conditioners; EL296V and EL195V furnaces; SLP98V modulating furnaces; G26, G61, and G71 legacy models; and 13ACX and 14ACX air conditioners. We also work on Lennox mini-splits and air handlers paired with any of these systems.
No. Having an independent licensed contractor service your Lennox system does not void the manufacturer’s warranty, as long as the correct parts and procedures are used. We follow warranty-safe practices on every job, and we’ll help you file any parts warranty claim you’re entitled to.
