This page is for Miami homeowners with a Lennox furnace that’s acting up. Whether it’s a Merit series in a Kendall rancher or an Elite in a Brickell condo, we know what breaks on these units and what it costs to fix them. Victor Mancini and our crew have worked on Lennox equipment across South Florida for years, and we write our repair guarantee on paper before we leave your house. If it fails inside 365 days, we come back free.

How Lennox Products Fail – and How We Fix Them

• Merit Series (ML193, ML195) ignitor failures. Miami’s salt air and humidity shorten the life of the silicon nitride ignitor faster than Lennox’s manual suggests. We see homes within three miles of Biscayne Bay eating ignitors every three to four years. We keep OEM and quality aftermarket ignitors on the truck, replace them in about an hour, and check the flame sensor while we’re in there.
• Elite Series (EL296E, EL296V) pressure switch trips from blocked condensate lines. High-efficiency Lennox units condense moisture; in Miami’s damp, mold-friendly air, condensate traps clog on a schedule. The furnace reads that clog as a pressure switch fault and locks out. We don’t just clear the line: we clean the trap, verify drain slope, and test the switch so the lockout doesn’t come back in two weeks.
• Signature Series (SLP98V) modulating gas valve calibration drift. The SLP98V is a wonderful machine when it’s dialed in, but its modulating valve can drift out of calibration and make the furnace hunt: fire high, drop low, fire high again. We use a manometer to set gas pressure to Lennox’s spec for your altitude and vent length, not just the default.
• Heat exchanger strain on older G50 and G51 units. These workhorses ran for two decades in plenty of Miami homes, but coastal corrosion eventually stresses the heat exchanger. We inspect with a borescope camera, show you what we see, and only call it done if the exchanger is sound. If it’s cracked, we say so plainly and talk through your options with real numbers.
• Blower motor capacitor and bearing wear across all Lennox lines. The blower motor on a Miami Lennox furnace runs a lot, even in “winter” that feels like everyone else’s spring. Capacitors weaken, bearings get noisy, airflow drops. We test capacitance under load, replace with matched-spec parts, and catch the problem before it takes the board down with it.

Our Lennox Furnace Repair Process

1. 1
   Live answer, real scheduling. You call, a person picks up. We give you a firm arrival window, not a four-hour shrug.
2. 2
   Diagnosis before dollars. Our technician checks the sequence of operation, pulls error codes, and runs the furnace through its cycle. We test the flame sensor, pressure switch, ignitor, and board with real meters.
3. 3
   Written price, no surprises. Before we open a single panel, you get the repair cost in writing. That number doesn’t change at the door. That is The Kingswell Way, plain and simple.
4. 4
   Parts decision, explained straight. Where it matters for safety or warranty, we use OEM Lennox parts. Where a quality aftermarket part matches or beats the original, we tell you and we price it lower. You decide with the facts on the table.
5. 5
   The repair, the test, the cleanup. We fix it, run the furnace through ten full cycles, check combustion and airflow, and leave your utility closet cleaner than we found it. You get a written 365-day guarantee on the way out.

Why Miami Homeowners Call Cold Harbour Heating and Air Miami for Lennox Work

We’re independent, not a factory shop, and that works in your favor. We service nine major brands including Lennox, Carrier, and Trane, so the technician at your door knows your equipment by touch, not by search engine. Since 2003, we’ve operated as an independently owned and operated member of the Kingswell network, bound to the same written standards: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.

Victor Mancini started his HVAC training at Los Angeles Trade-Technical College and spent close to two decades in the field before bringing his crew to South Florida. From Coconut Grove tune-ups to full replacements in Brickell high-rises, the same rule applies: tell them the price, show up on time, back the work – everything else takes care of itself. Every repair carries the 365-Day Done Right Promise. If it fails within a year, we return and make it right at no charge. That’s not a policy we apply case by case. That’s the only way we’ve done it since day one.
