Worst company in terms of service and customer service on HVAC units....includes coil/Furnace etc... I am happy with carrier products and service very reliable from consumer perspective but pathetic service by lennox..stay away from lennox products...

I purchased an ECM Lennox heater 10 years ago (final install inspection: 4/2). The blower motor failed on 5/11—just 1 month and 9 days after the 10-year warranty expired. When I contacted Lennox customer support, I hoped they’d make an exception given how close it was to the warranty period, as a sign of standing behind their product. Instead, I was told no exceptions are made—period. To escalate the issue, I was transferred to another queue. After waiting 5 minutes, the call disconnected. I called back, waited another 5 minutes, and was disconnected again. No callback, no resolution, just wasted time. This experience speaks volumes: Lennox doesn’t value customer loyalty or product longevity. For a premium brand, the refusal to offer even minimal goodwill—paired with abysmal service—is unacceptable. Combined with the suspicious timing of the failure (right after warranty expiration), it’s hard not to feel the product was engineered for planned obsolescence. A 10-year warranty equals 3,650 days of promised coverage. My unit failed just 39 days past that—a mere 1% over the cutoff. Yet Lennox wouldn’t budge, treating it like a decade-old debt come due. I will no longer purchase Lennox products or recommend them to others. If you’re considering this brand, factor in their rigid policies and lack of post-warranty support. There are better options out there.

Had to purchase a new circuit board after 14 months, apparently the old version of the circuit board had issues so they came out with an updated version. And of course the warranty expires after 12 months. Gave them multiple opportunities to assist as the quality of parts I’ve received from them fail just after the warranty. They did nothing, asked to speak with a manager, told me there’s no reason to escalate. I asked if an unhappy customer was not a reason to escalate? No response. Unwilling to help even in the slightest. Will never use Lennox again. The large corporations just showing how they don’t care about customers. Too bad

Absolutely useless support. Tried to call about a newly installed Lennox $ 12,000 HVAC system that cycles on and off in under 2 min, to ask if there was an adjustment that could correct it. She just kept saying call the installer, which I had already done twice & paid for service calls that did nothing. Still don't know if it's a faulty new Honeywell 9000 thermostat or the Lennox unit. Both deny it is their problem. I will never touch Lennox again.

We live in Northern Maine and have been deeply disappointed with Lennox’s customer service. Since there are only a couple of service providers for the entire state, they seem to treat customers as if they’re "precious" and indispensable. When we called to ask a simple question about our system or inquire about ordering a part, they flat-out refused to help unless we provided the name of our repair technician. They wouldn’t offer any information or assistance. The lack of care and refusal to provide basic support was shocking. We’re now seriously considering replacing our furnace entirely just to avoid dealing with Lennox ever again. After sharing our experience with some neighbors, they’ve decided to steer clear of Lennox as well. If you're considering their products, avoid at all costs—the customer service is not worth the hassle.

Absolute garbage company. I would give Lennox 0 stars if I could. I own the top of the line Lennox modular furnace. I live in Northern Ontario where it is COLD!!! Last night the temperature was -22. With the wind chill it was -32 degrees The furnace is a little over 10 years old and if the course the warranty just expired. The furnace stopped working on January 08/25 so I called in the technician to repair the furnace. Supposedly a circuit board needed to be replaced at a cost of $800.00. The part was ordered and now I’m told it will not arrive until January13/25. Seriously!!! A furnace is not a luxury in Northern Ontario it’s a frickin necessity. When I was researching furnaces I was warned about Lennox furnaces and their terrible customer service. I should have listened. Now I’m out buying heaters to put throughout the house to avoid being frozen out. Do yourself a favour AVOID any Lennox products because there is no such thing as customer service. If the furnace breaks and it will; you will not have heat in your house for quite sometime.

M 30 thermostat M 30 thermostat has many good features and the advanced settings are easily followed. I especially like the programming for individual days, and the performance report. With the performance report I am able to calculate the fuel that I use in the oil furnace. Also the away setting is very handy just to be leaving for a while. I do have a complaint though; this is the most and inaccurate temperature thermostat I have ever used. The only time that it is accurate is when it's off and not doing anything. Room temperature and thermostat temperature are 5° off. Let say we come home and need Air-conditioning mode, if its 80° room temperature and you turn the air conditioning on to 72°. About 20 min. the thermostat will say it at 72° and turn off THE compressor but the room temperature says it's only 76.5 or 77 degrees. The offset in advance settings does not help this either. As a matter fact after trying every offset and every advance setting to see whether I can get this thermostat to at least be acceptable, we just set it to 68 degree when it start again. Like I said before the only time that it's accurate with room temperature is when it's off. Now let talk about heat! Heat always over shoots the setting by 4 degrees. Setting the offset does not correct the problem. The M30 is set at 71 degrees heat but room temperature is 75 degrees and when you use the offset to try to correct high room temperature, then it does not come on when it gets cold (68 degrees) in the room.. Your installer booklet with set up info does not really tell you how to set the offset. Also the settings are not concurrent between summer, winter or spring/fall. Please don’t tell me to contact my installer as there have been other problem with this new duel fuel system and it appears I know more about these thermostats and this HVAC install than they do. Just for your reference this is the 3RD thermostat that they traded out.

Bought an item what I was assured would fit in my car, needless to say it was totally incompatible, asked for a refund as it is promised up to 90 days, I returned the item to them, now they are playing silly games, I followed their instructions to the mark, I feel they are not going to give me my refund, i strongly suggest you do not use this company, total rip off
