Question DetailsAsked on 6/10/2016

How much should it cost to replace a lennox xc15 blower motor and txv valve?

HVAC company said I need a new blower motor (not running) and a TXV valve due to a line restriction. Labor quote is $2200. Seems extremely high. I am in TX.

Do you have the same question? Follow this Question

Below are links to a few similar previous questions FYI - not knowing specific part numbers involved or whether you are in a high or low cost area of the state, $500-800 would probably be a reasonable cost range for the blower motor changeout including parts, assuming the main circuit board is not fried too. (Motor itself appeaars to list for about $300 - $225 on Amazon, so a pricier one, so contractor charge-out probably about $400).

TXV valve probably in the $350-450 range to change out including parts (retail about $175 for part) - total cosst can be more or less depending on manufacturer and especially on whether it has isolation valves on both sides of it allowing removal and replacement without having to pump out the refrigerant and then recharge it after the repair - that along is typically $100-200 if needed, which it is in probably most makes. (Isolation valves in A/C systems are a highly manufacturer-dependent thing - some put them in to allow maintenance without having to remove the gas or add much back in, some will not put them in because each shutoff valve is one more valve and one more fitting that can have a slow gas leak over time.)

You said LABOR quote was $2200 - and in Texas (except ritzier areas around DFW) your labor costs should not be on the high end. This is getting into the range of a new unit installation labor cost, so yeah - sounds HIGH to me - even if that were the entire cost including parts sounds high by 50% or more, so I would definitely be getting bids from other contractors.

The other thing you need to consider - and would probably cost $100-150 by new contractor for a new diagnosis but might save you $1000 or more - is whether these items were actually bad, if the problem was mis-diagnosed (because I cannot see any strong link causing these two components going out at the same time), or if maybe there is nothing wrong with those major components at all and the contractor was pushing for needless replacement as a scam. No way to tell from here, of course, but those two components going out at the same time would raise at least a yellow flag to me that maybe you were being scammed - the $2200 labor cost would reinforce that opinion, because that is about as much or more than the labor for putting an entire new unit in should cost.

Also - if there is a "line restriction" - what is he doing about that ? Or is he assuming that the TXV valve is the problem without testing it ? Could just be a plugged filter/drier for instance, which is about $70 for the part and maybe again $100-200 labor to install.

Oh - BTW - my personal opinion - when you finally decide to replace this system, I would recommend something other than a Lennox - a fair number of thoughts on brands and their reliability as well as on the issues of relative value and life-cycle cost of repairing an older (say over 10-15 years old) unit versus buying a newer, higher efficiency unit can be found in the Home > HVAC link in Browse Projects, at lower left. From my experience Lennox, Goodman, etc give you quality commensurate with their equipment cost - pay little, get little. If you want peace of mind I recommend Carrier.
