    What exactly does a contractors warranty cover?

    Not talking about the equipment manufacturers warranty here. Their warranty covers their equipment, but how about all the other stuff involved that is up to the contractor to do to ensure the equipment will do its job, like an accurate manual J & D & S & T?
    What does a homeowner need to see in that warranty to ensure they are covered if the equipment selected is not appropriate per the manual S, or is oversized per manual J, or the ductwork is grossly undersized per Manual d?
    Any homeowners with existing warranties please feel free to post the details, but remember the rules here and do not include anything that would identify the contractor or person involved; company names, peoples names or phone numbers etc... is not allowed.

    I simply state in my contracts that I gaurantee for 1 year against workmanship and defects, not 100% sure but I think on new construction there is a 2yr requirement, at least on a GC.
    It's hard to stop a Trane. but I have made one helluva living keeping them going.

    A lot of what type and length of warranty is going to be dictated by state and/or local juridictions. I'm sure from state to state they are all very similiar. Its 1 year in Texas and the 2 year new construction thing is kinda hazy. As SM said. It's the GC/builder that falls to the hvac guy. As far as the manual J. I have a few customers that this means nothing too and don't care about it. I've got one guy who wants his house 63 all the time and we actually manage to maintain it for the most part. Unfortunately R410 doesn't like that cold a temp.
    I like DIY'ers. They pay better to fix.

    In my state, for a year I own it lock, stock and barrel. If it breaks, I have to fix it at no charge to the owner, unless they broke it.

    After a year, then owner gets any warranty parts at no charge, and no labor charge if the manufacturer offers warranty labor reimbursement.

    I personally tend to figure in three hours of labor cost into every system, for warranty purposes.

    With the low quality of equipment coming out these days. You have to figure at least 3 hrs of warranty labor in. With all the bad txvs, leaky coils, bad motors or capacitors.

    Is there any language in your warranty regarding a manual J being accurate within a certain percentage, rooms being of equal temp throughout to a certain percentage, that ductwork/airflow is within tolerances to a certain percentage, that the equipment is correct for their design conditions etc...? Basically that the system is operating the way it should and at its design efficicency. Like if 2 rooms of the home is not getting the proper amount of cfms & at the proper temp per the room by room manual J, does the warranty cover it?

    In our state it's 1-year parts and labor on installed equipment/systems. If you put the equipment into a system that's inadequate to handle the equipment, then the contractor has a problem. Unfortunately it would take a legal claim in most instances to make that stick. Our building codes call for a Manual 'J' load calc and a MasCheck that the equipment can be no more than 25% oversized for heating. But I've yet to meet the building inspector who's ever asked anybody for one.

    I have a personal close friend who's having a new house built in an over 55 development. I did a load analysis and determined that the furnace is too big, the blower is too big and the proposed AC is too big. I suggested he have a talk with the builder and at the very least, request a copy of the load analysis. They were putting in a 3.0-ton AC unit with a 1-stage Trane furnace with a 3.5-ton blower. I checked the stats and there's no way the blower will slow down enough to provide proper airflow for the needed 2.0-ton system per Manual 'J' and Manual 'S'. Naturally, there is no load analysis, the contractor balked at replacing the furnace so the homeowner settled for a 2.5-ton AC unit. Now after they pass papers on the house our company will have to go in and change the blower motor to an ECM and set it for proper airflow for both the furnace and the AC system, despite the AC being oversized. I wouldn't have stood for the errors and volunteered to speak with the builder but the friend is a pacifist and so gets screwed at every turn. Perhaps he likes it that way but that's how far the state building code gets followed around our neck of the woods.

    that's energy code that dictates that. If I don't fall into a code minimum design then I would be against my warranty. If I meet code then I am in the right, unless I specifically designed to a homeowners specs. Then in which I need to meet or exceed those design criteria.

    What is interesting to me is that not one homeowner has posted on this thread. With the amount of homeowners who have threads complaining of being screwed over on their installs, and with all the others with questions concerning a contemplated system replacement, you would think they would see some value in finding out what a good warranty entails.

    My warranty covers all work for one year that they did including if something breaks on the equipment . I had new ducts installed for a second floor that never had ducts before. The material and workmanship is covered on the new ducts but there was no guarantee on how it would perform. They could not get the required duct size through the floor joist. They did their best making custom square ducts but it was still not what was needed. I okd it since we went over options up front and I knew from the beginning my options. The second floor stays within a couple degrees of the main floor even when we are in the mid 90s so I am happy. I purchased the ten year labor warranty but I am sure you guys know the ins and outs on that. I know I will be responsible for what I refer to as disposable items (refrigerant, welding stuff, and after hours calls).

    After all the bids I originally got I don't remeber one company offering performance warranty. Infact if some of them did I don't know how they would ever be able to honor them. I had companies that either did not do load calcs and offer the wrong size to companies that did do load calcs that ignored the numbers instead to push for a five ton unit (got a two stage three ton and love it). Most of the companies never looked at the duct work so they would not have known the return was way to small. Over all I think people look more at the price of something instead of looking at long term possible cost.

    I guess I posted this thread in the wrong forum? I didn't want to throw it in the general discussion area cause I don't think that forum gets as many viewers. I guess I should have since my question was designed to get everyones imput, not just the pro's.
