Heating Maintenance Plans in Los Angeles — Pre-Winter Furnace Service

EA Mechanical heating maintenance plans in Los Angeles cost $189 to $399 per year in 2026 and pair the spring AC visit with a fall furnace service. The fall visit is the safety-critical one: heat exchanger inspection with a combustion analyzer, CO testing at the supply registers, ignition system service, and blower performance check. This is different from our $87 one-shot tune-up — see /ac-heating-tune-up/ for that. Call (818) 988-9060.

Furnaces that go 2 to 3 years without service are responsible for most of the avoidable mid-winter no-heat calls we run. The most common failure modes — a fouled flame sensor, a worn ignitor, a clogged condensate trap on a condensing furnace — are 5-minute fixes during a planned visit but become a 4-hour after-hours emergency in February. The fall maintenance visit is the cheapest insurance available against winter system failure.

The heating-side service is also where we catch the more serious safety items: cracked heat exchangers (CO leak hazard), gas-leak smells, and degraded venting. Our technicians carry calibrated combustion analyzers on every truck and document CO levels at the burner and supply registers. Plans cover homes across Tujunga, Sunland, La Crescenta, Burbank, Glendale, Pasadena, and the wider San Fernando Valley. Call (818) 988-9060.

What the Fall Heating Visit Covers

• Heat exchanger inspection — visual scan plus CO test at supply registers with the burner running. The single most safety-critical check we perform.
• Combustion analysis — calibrated meter measures CO and oxygen at the burner; flue draft is verified.
• Ignition system service — clean the flame sensor, inspect the hot-surface ignitor for cracks, test gas-valve response time.
• Blower motor and capacitor — measure amp draw, capacitor microfarads, and bearing condition.
• Gas-line check — visual inspection of accessible gas piping with leak-detection solution at fittings.
• Filter replacement and condensate trap clean (condensing units only).

Why Fall Timing Matters

September and October are the right window for heating maintenance because the system has been off all summer (so dust and pests have settled in places that produce ignition problems on first fire-up), the ignitor and flame sensor have not been cycled in months (so a marginal one will fail at first start), and CO/combustion baselining is most accurate when the system is started cold. Booking the visit before the first cold snap means the failures get caught during a planned visit at planned cost — not at midnight in a heat emergency at after-hours rates.

Plan Tiers — Same Structure as the AC Plans

Heating maintenance is bundled into the same EA Mechanical annual plans as AC: Essential at $189/year (two visits — spring AC, fall heating), Standard at $279/year (adds 10% parts/labor discount and written reports), Premium at $399/year (adds 15% discount, no diagnostic fee, comprehensive performance measurement). Plans run on a two-visit cadence so the heating-side and AC-side service both happen in their proper season.

CO Testing — Non-Negotiable Safety

Carbon monoxide is colorless, odorless, and produced any time fuel is burned. A healthy furnace produces well under 9 ppm at the supply registers; a cracked heat exchanger or fouled burner can push that to dangerous levels. EA Mechanical technicians carry calibrated combustion analyzers and document CO at every visit. If we find an unsafe condition we red-tag the unit and explain your options on the spot.
