This page is for Riverside homeowners with a Lennox furnace, whether it’s a G61, SLP98, EL296, or something older that’s been heating a house on Victoria Avenue for twenty years. Luis Serrano and our crew know which Lennox series tend to fail in certain ways, and we’ll lay out the repair versus replace numbers plainly before any work starts.

How Lennox Products Fail – and How We Fix Them

• Pressure switch trips on SLP98 and EL296 models. Lennox variable-speed and two-stage furnaces rely on a pressure switch to confirm the inducer is moving exhaust. In Riverside, where dust from the Santa Ana winds gets pulled into closets and attic installs, the rubber hose connecting the inducer to the switch gets clogged with fine silt. The furnace will click but won’t light. We clean or replace that hose and test the switch with a manometer rather than guessing, which is what separates a one-visit fix from a parts cannon approach.
• Ignitor failure on G61 and G71 series. Lennox furnaces from the mid-2000s through the early 2010s used a silicon nitride ignitor that’s durable but eventually cracks after thousands of heating cycles. The symptom is a furnace that runs the inducer, then gives up before the burners fire. We replace it with a Lennox OEM ignitor when the unit is still under warranty, and a quality nitride aftermarket part when it isn’t. Prices land around $250 to $400 installed.
• Heat exchanger rust-out on older G26 and G32 models. These units are workhorses, but the tubular heat exchangers don’t last forever. Homes near the Santa Ana River corridor see slightly higher indoor humidity in winter, and on a 25-year-old Lennox that can mean rust streaks on the cabinet exterior and a burner flame that dances yellow instead of blue. If we see that on a maintenance visit, we’ll show you photos and walk through whether a heat exchanger replacement under warranty makes sense or whether a new EL297V is the better long-term play.
• Blower motor capacitor failures on Lennox units with PSC motors. Many Lennox furnaces in Riverside use a permanent split capacitor blower motor. When the capacitor fails, the blower either won’t start or runs slow, so rooms at the far end of the house stay cold even though the furnace fires. We test the capacitor with a multimeter, and if it’s weak, a replacement runs $180 to $320. If the motor itself is seized, we’ll discuss a motor swap and what it costs before we turn a screw.
• Smart thermostat communication errors on iComfort-enabled systems. If your Lennox furnace is paired with an iComfort S30 or E30 thermostat and you’re getting a “communicating system malfunction” message, the furnace and thermostat may have lost their handshake. Sometimes it’s a low-voltage wiring issue, sometimes a failing control board. We’ll isolate it methodically: thermostat, wiring, then board. That order matters, because swapping a board first is a $600 fix for a problem that might have been a $100 wiring repair.

Our Lennox Furnace Repair Process

1. 1
   You call, a person answers. No voicemail queue, no call center script. We ask what your Lennox is doing and what you’re hearing. Luis’s line: “Tell me what’s happening inside the house, and we’ll figure out the rest.”
2. 2
   We arrive with shoes covered and a plan. Every technician is background-checked and uniformed. Drop cloths go down in front of the furnace before any tools come out, and we protect the flooring between your entry door and the equipment.
3. 3
   Diagnosis with actual tests. We measure gas pressure at the valve, test the ignitor’s resistance, check the pressure switch with a manometer, and inspect the heat exchanger where accessible. We don’t guess. We find the failed part and quote a written price before any repair begins.
4. 4
   The parts decision, explained. If your Lennox is under warranty, we use OEM parts and handle the paperwork. If it’s out of warranty, we’ll show you the OEM price and a quality aftermarket option and let you choose with the numbers in front of you.
5. 5
   Repair and verification. We make the fix, run the furnace through three full cycles, and check the temperature rise and burner flame. If it doesn’t pass, it isn’t done.
6. 6
   Cleanup with proof. Before we leave, we take a photo of the work area and show you. The C.A.R.E. values aren’t a poster, they’re a checklist: Clean up like it’s our own home, Ask before moving anything, Respect your time and quiet hours, Explain the price before the work.

What Lennox Furnace Repair Costs in Riverside

Most Lennox furnace repairs in Riverside fall between $150 and $700, and the final number depends mostly on which part failed. Here’s what we see most often:

• Flame sensor cleaning or replacement: $150 – $250
• Ignitor replacement: $250 – $400
• Pressure switch replacement: $200 – $380
• Blower motor capacitor: $180 – $320
• Gas valve replacement: $400 – $700
• Blower motor replacement: $450 – $700

What moves the price is whether the part is OEM or aftermarket, how long it takes to access the furnace (attic installs in older Riverside homes take longer than garage closets), and whether anything else failed downstream. You’ll get a written price before any work starts, every time. Call (707) 340-6380 for a free estimate, and we’ll give you an honest range over the phone.
