Lennox AC repair in West Palm Beach typically runs $150 – $650 depending on the part that failed and whether your system uses R-410A or the newer R-454B refrigerant. Most Lennox repairs we handle are done in a single visit, and we carry common OEM-spec parts on our trucks so you’re not waiting days for a second trip. We’re an independent Lennox service provider, not a factory warranty shop – which means we fix what’s actually broken and tell you the truth about whether a repair makes sense before quoting a replacement.
This page is for West Palm Beach homeowners with a Lennox system that’s blowing warm, short-cycling, making a new noise, or just not keeping up. If that’s you, call (728) 220-0996 and Devin or one of our techs will help you figure out what’s going on. As Devin puts it: “Tell me what it’s doing, and I’ll tell you what it needs – no guesswork, no runaround.”
How Lennox Products Fail – and How We Fix Them
- XC and XC-Elite series compressor contactor failures. In West Palm Beach’s salt air and constant summer load, the contactor on Lennox XC series condensers pits and burns out faster than on many competitors. The unit will hum but the fan won’t turn. We replace the contactor with a heavy-duty silver-alloy equivalent, not a economy part, and clean the load side connections so it doesn’t happen again in eighteen months.
- Merit series capacitor failures – the “click and nothing” call. Lennox Merit line units (the ML14 and ML17 especially) run a single dual-run capacitor that takes a beating in our heat. When it fails, you either hear a click and nothing, or the compressor tries to start and trips the breaker. We keep OEM-spec 440V rated capacitors on the truck. A OEM direct-replacement capacitor from the factory parts network is usually a 1-2 day wait in South Florida, so we stock exact-match aftermarket equivalents with equal or better temperature ratings.
- Evaporator coil corrosion on Elite series air handlers. Lennox Elite air handlers installed in humid West Palm Beach attics are prone to formicary corrosion on the aluminum fin surface – it looks like spider-web pitting. That causes pinhole refrigerant leaks, which shows up as a system that runs but never gets cold enough. We leak-test with nitrogen and electronic sniffers before we ever add refrigerant, because adding to a leaking system is throwing money away.
- Variable-speed ECM motor module failures on XP and XC heat pumps. When a Lennox variable-speed blower stops ramping up properly, homeowners often think the thermostat is bad. Nine times out of ten it’s the module, not the motor. We bench-test the module before replacing the entire motor head, which saves between $400 and $900 versus a full replacement that other shops push unnecessarily.
- Thermostat communication faults on iComfort systems. The Lennox iComfort communicating thermostat is a great control, but when its RS485 communication drops out, the system goes dead or locks into one stage. In West Palm Beach’s frequent voltage sags during summer afternoon thunderstorms, we see this constantly. We always check for a firmware re-pairing before condemning the thermostat board itself.

Our Lennox AC Repair Process
- 1
You call, a person answers. Not a voicemail tree. You tell us what the Lennox unit is doing, and we give you a rough idea what the likely culprits are and a window for arrival.
- 2
We arrive with your tech’s name and photo already sent. The tech who shows up is the person in the text we sent you, and they’ll show a photo ID badge at the door before stepping foot inside.
- 3
Diagnosis comes first, and we show you what we find. On a Lennox we check the obvious first – capacitor, contactor, refrigerant pressures, thermostat wiring, and the condensate safety if the pan is full. We’ll take a photo of the failed part and explain what it does in plain language.
- 4
Parts choice is transparent. If the part is available as OEM-spec and in stock, we use it. If there’s a manufacturer backorder, we give you the option of a quality aftermarket equivalent with equal or better ratings and explain the trade-off in writing before any work proceeds.
- 5
You approve a written price before anything gets touched. That’s the only way we work. No surprises at the end, no “while we were in there” add-ons.
- 6
We test, verify, and hand you a written guarantee. We run a start-up cycle, check pressures and amp draw, and make sure the condensate line drains. The repair is covered in writing for 365 days. If it fails within that year, we come back at no charge – no argument, no re-diagnosis fee.

| Thermostat repair or replacement (iComfort or aftermarket) | $180 – $450 |
| Fan motor replacement (condenser blower) | $300 – $550 |
| Refrigerant recharge (diagnosed leak, not a top-off) | $250 – $650 depending on refrigerant type and charge amount |
| Compressor repair (electrical or valve issue) | $400 – $650 |
What moves the price is parts availability (OEM Lennox parts sometimes have a 2-5 day wait in Palm Beach County) and whether your system runs the older R-410A refrigerant or the newer R-454B, which costs noticeably more per pound. We give you the exact written price before anything is replaced. Call (728) 220-0996 for a free estimate on your specific Lennox system.
Why West Palm Beach Homeowners Call Brandt HVAC Co West Palm Beach for Lennox Work
We’re not a generic “we service all brands” shop that looks at a Lennox the same way they look at a Goodman. Our techs carry Lennox-specific diagnostic notes, know which series have what failure patterns in our humidity and salt air, and stock the parts that those units actually need in West Palm Beach. If your Lennox is under the manufacturer’s parts warranty, we handle that too – we’re an independent provider, so we document everything for your warranty claim without making you fight the paperwork.
We also work on Carrier and Trane daily, so if you’re weighing whether to repair the Lennox or consider what a replacement from another brand would actually cost you, we’ll give you a straight answer based on what we see, not a pitch. Every tech we send is background-checked and identity-verified under the Threshold Verified standard, and you’ll know their name and see their photo before they arrive. If the repair doesn’t hold up, our 365-Day Done Right Promise means we come back and make it right. Free.
FAQs
Yes, we work within the Lennox parts warranty framework as an independent service provider. That means we can diagnose the failure, confirm the serial number and install date, and process the parts claim with Lennox on your behalf. You’ll still pay the labor and refrigerant, but the failed part itself is often covered for 5 to 10 years depending on your model line and whether the system was registered. We’ll walk you through exactly what’s covered before we start.
In most West Palm Beach neighborhoods, we can have a technician to you the same day if you call in the morning, and often within a few hours. After 5 p.m. and on weekends, our phones are still answered by a live person, not a machine, and we keep emergency slots open for no-cool calls when a Lennox goes down in August heat. Call (728) 220-0996 and we’ll give you a real window, not a vague “sometime Thursday.”
Honest answer: it depends on the compressor. If your Lennox is under 12 years old and the compressor, coil, and air handler are sound, a $300 capacitor or contactor replacement is almost always worth it. If the compressor itself has failed and the unit is out of the ten-year parts warranty, we’ll tell you that a repair doesn’t make sense and give you a written replacement quote instead. We never recommend a replacement when a $200 part will honestly get you another three summers.
We prefer genuine Lennox OEM parts whenever they’re available, and we use them for most mechanical work – motors, boards, controls. But there are cases where a quality aftermarket equivalent is the better call, like capacitors and contactors, where a non-Lennox-branded part with a higher temperature rating will outlast a factory part in our Palm Beach County heat. We’ll always tell you which we’re installing and why, and the 365-day guarantee covers either one.
Turn the thermostat to “off,” check your air filter, and if the outdoor unit is humming but the fan isn’t spinning, don’t keep running it – the compressor is overheating. Call us at (728) 220-0996 and tell the person who answers what you’re seeing. A humming condenser with a dead fan is almost always a capacitor or contactor, and it’s a repair we can typically have done today, frequently without waiting on parts.
