Why the brand changes the repair
Lennox is known for signature Collection variable-capacity systems, SLP furnaces, and iComfort controls. Those engineering decisions determine how the equipment fails, and therefore how it is diagnosed. A technician who treats every ac repair the same way will eventually get the part right by elimination – at your expense. We would sooner pull the fault history and take a reading, and be right at the first attempt.
Parts and warranty
We fit genuine Lennox parts wherever they are available, and our vans carry the ones that fail most often. Where a part for an older model is genuinely no longer produced we say so plainly rather than fitting something and hoping. Either way the part number goes on your invoice, and both parts and labor carry our written labor warranty.
Before you book
Have the model number to hand if you can. On Lennox appliances it is usually on the door frame, behind the kick plate, inside a drawer runner or on the rear panel depending on the unit. Photograph the rating plate and send it over if the number has worn, and we will read it for you. With the model confirmed, the parts that most often fail on your exact unit travel with the technician – which is how most of these jobs finish in a single visit.
