Lennox AC repair in Fort Lauderdale typically costs $150 – $650, and most calls are completed same day or next day depending on parts availability. We’re an independent Lennox service provider, which means we diagnose and repair the equipment without being tied to a manufacturer’s script or corporate parts pipeline. If you own a Lennox system in Fort Lauderdale and it’s short-cycling, not cooling, or making noise it shouldn’t, call (754) 354-6972 and we’ll get a written diagnosis in front of you before any work begins.
This page is for Lennox owners who want straight answers: what fails, what it costs, how long it takes, and who’s actually showing up. Marco Benitez and the team at Dalton Heating & Air Fort Lauderdale service Lennox equipment across Broward County, from older Merit-series splits in Victoria Park to newer Elite and Signature units in Rio Vista and Coral Ridge.
How Lennox Products Fail – and How We Fix Them
- XC and XP series compressor contactor pitting: The higher-end Lennox units (XC21, XP21, and the newer variable-capacity lines) pull more amperage at startup than basic single-stage units. In Fort Lauderdale’s salt air, the contactor points corrode faster and arc sooner. Symptom: the outdoor unit hums but the fan won’t spin. We replace the contactor with a sealed or coastal-rated part and check for voltage drop at the same visit.
- Merit series (ML14/ML17) capacitor failures: Lennox Merit-series condensers ship with capacitors that run hot in South Florida humidity. A weak capacitor makes the compressor struggle to start or the fan run slow. Symptom: the house struggles to hit setpoint on the hottest afternoons, or the system trips a breaker. We test capacitance under load, not just at rest, then replace with a higher-tolerance aftermarket capacitor rated for coastal climates when it’s the right call.
- Evaporator coil leaks on 2015 – 2020 slab-coil units: Lennox had a run of slab-style evaporator coils that corrode prematurely, especially in humid coastal installs. Symptom: the system runs but blow air isn’t cold, and ice forms on the copper line at the air handler. We pressure-test with nitrogen, locate the leak, and price a coil replacement against an R-410A recharge so you can make a decision based on numbers, not pressure.
- Signature and Elite series ECM blower motor failures: Lennox Elite (EL296V, EL18XCV) and Signature (SL280V, SLP98V) units use ECM variable-speed blower motors. When the module fails, symptom is often intermittent airflow or a sudden drop in airflow with no warning. We bench-test the motor module, and when it’s dead, we’ll price an OEM replacement against a quality aftermarket option with the pros and cons of each in writing.
- Thermostat communication faults on iComfort systems: Lennox iComfort S30 and E30 thermostats sometimes lose communication with the outdoor unit after a power surge or brownout, which Fort Lauderdale gets plenty of during summer storms. Symptom: thermostat displays an error code, or the system won’t respond to setpoint changes. We check the low-voltage path first, then re-bind the thermostat to the control board before we ever start replacing parts.
Styles & brands we work with
Our Lennox AC Repair Process
- 1
You call, a live person answers. No voicemail tree. We listen to the symptom, ask about the unit’s age and model, and book a window. (754) 354-6972.
- 2
We show up on time and confirm the problem. Uniformed, background-checked tech. Before anything gets opened, we walk the property with you and listen to what changed.
- 3
Written diagnosis before any work. We test the system, find the fault, and put the exact repair and price in writing. You decide. Nothing gets opened beyond the diagnostic access panel without approval.
- 4
Parts decision, explained. OEM Lennox part or quality aftermarket? We lay out cost, warranty, and availability for both. Some older Lennox parts have lead times in Fort Lauderdale; aftermarket can get you cooling same day.
- 5
The repair and the test. We install the part, run the system through a full cycle, measure refrigerant pressures, amperage draw, and temperature drop across the coil.
- 6
You get the guarantee in writing. Every repair carries a written one-year guarantee. If the repair fails inside that period, we return at no charge. That’s the Garrison Standard, and it’s not negotiable.

AfterWhat Lennox AC Repair Costs in Fort Lauderdale
Most Lennox repairs in Fort Lauderdale run $150 – $650. Capacitor replacements land on the low end, $150 – $275. Contactors and small electrical parts run $180 – $350. ECM blower motor modules and condenser fan motors fall in the $350 – $650 range depending on whether we use OEM or quality aftermarket. Refrigerant recharges are priced by the pound after a leak test, and we’ll give you that number in writing before any refrigerant is added. A failed compressor on an out-of-warranty Lennox is usually a replacement discussion, not a repair, and we’ll show you the math on that honestly.
What moves the price: the model line (Merit parts are generally cheaper than Signature variable-speed components), parts availability for your specific unit, and accessibility of the air handler or condenser in your home. We give free estimates on every call, so you’ll know the exact price before we start turning wrenches.
Why Fort Lauderdale Homeowners Call Dalton Heating & Air Fort Lauderdale for Lennox Work
We’ve been repairing Lennox systems in Fort Lauderdale long enough to know the difference between a bad capacitor and a compressor that’s on its way out. We service nine major brands, so when a Lennox part is backordered, we’re not standing around waiting. We’ll source the right component from our supply network, and our techs work on Carrier and Trane equipment too, so you’re covered no matter what’s in the closet.
Every repair is priced in writing before work begins. Every repair carries a written one-year guarantee. If the work fails inside that year, we come back free. The Garrison Code has been our standard since 2003: arrive inside the stated window, price in writing first, do the job by the book, leave the site clean, and stand behind the work for a full year. Marco Benitez runs the Fort Lauderdale team that way because it’s the only way he knows.
FAQs
Lennox compressors typically carry a 10-year limited warranty when registered within 60 days of installation, but coverage depends on registration, the installing contractor, and whether the unit was properly maintained. We check your model and serial number against Lennox’s warranty database during diagnosis and tell you exactly what’s covered before any repair is priced.
When a genuine Lennox part is the right call for the unit’s age, warranty status, and your budget, we install it. For older units or when an OEM part has a long lead time, we offer quality aftermarket alternatives with the trade-offs in writing. You’ll always know what’s going into your system and what the warranty is on that part.
Here’s the rule we use: if the repair cost is under 50% of a new system’s installed price and the unit is less than 10 years old, repair usually makes sense. If the compressor is done or the coil is leaking and the unit is 12+ years old, replacement often costs less per year of remaining life. We’ll show you the numbers for your specific situation and let you decide.
For the most common failures, capacitors, contactors, and small electrical faults, yes, we complete the repair same day. For less common parts, like variable-speed ECM motors or specific Lennox control boards, it depends on what our Fort Lauderdale supply houses have in stock. We’ll tell you the part availability before we leave and give you a firm return date.
Ice on the copper line or evaporator coil means low refrigerant, restricted airflow, or a failed blower. Running it frozen can destroy the compressor, so turn the system off at the thermostat and call us. We’ll thaw it, find the leak or airflow restriction, and give you a written fix before any repair starts.
