This action was brought to foreclose a mechanic’s lien, filed by the plaintiff on the 22d day of July, 1892. The plaintiff and defendant entered into a contract by which the plaintiff was to furnish and set up complete a furnace of sufficient heating capacity to heat defendant’s house, and complete same in a good arid workmanlike manner.
*135The contract provided that the sum of $1,045 should be paid to the contractor (plaintiff) in installments, as follows : $470 when the rough piping was in, $470 when the entire apparatus was set up and completed, and the balance, $125, thirty days from the last payment, and within thirty days after the contract was completely finished; providing that in each of said cases the architect should certify in writing that all the work had been done to his satisfaction. It is further provided by the contract that no certificate given or payment made under this contract, except the final certificate and final payment, shall be conclusive evidence of the performance of this contract, either wholly or in part, against any claim of the owner.
On November 21, 1892, the architect gave a certificate in the following language:
, “ November 20th, 1892.
“ E. D. Haskins — Louis W. Gay, contractor for heating, is entitled to second payment of $470 as per contract. Amount previously paid, $470. Amount of contract, $1:045.00.
“ John S. Bowe.” '
This sum was paid and receipted for by the plaintiff on the twenty-second day of November, leaving the final installment of $125 unpaid. No other or further certificate was given, and no final certificate, as required by the contract, was given, unless this one can be so considered.
This becomes important when we consider that the plaintiff in the specifications guaranteed that the apparatus would warm the rooms to which radiation is conducted to seventy degrees Fahrenheit in the coldest winter weather. The work was to be -done according to the drawings and specifications, and they became a part of the contract, and must be resorted to to determine whether the certificate given November twenty-first was the final certificate contemplated hy the contract.
The provision deferring the final payment of $125 for thirty days was probably intended for the purpose of affording the *136owner and architect time and opportunity to determine whether the work was completed according to the terms of the contract before he could truthfully certify that the work was done to his satisfaction. This is especially the case when the, sufficiency of the heating must he determined within the thirty days limited by the contract. Hence the contract provides, as I understand it, that before the final payment of $125 becomes absolutely payable the architect must certify in writing that all the work upon the performance of which the payment became due has been doné to his satisfaction. The certificate of the architect given to secure the second payment of $470, while not in the language of the contract, is probably a sufficient compliance with its terms under the authorities. Wyckoff v. Meyers, 44 N. Y. 143 ; Snaith v. Smith, 7 Misc. Rep. 37; 27. N. Y. Supp. 379.
Arid a certificate was required by the terms of the contract, before the last installment became payable, before the defendant would be absolutely concluded from setting up the defense that the work was not in accordance with the terms of the contract. If the architect had given the final certificate, the third one required by the contract, that the work was done to his satisfaction, it would have been conclusive upon that question in the absence of fraud or mistake. Wyckoff v. Meyers, supra.
But the giving of such a certificate by the architect is a condition precedent to the absolute right of enforcing payment of the final installment. Wangler v. Swift, 90 N. Y. 38.
It seems to me, therefore, that the court erred in ruling out the defendant’s evidence tending to show that the work was not completed in accordance with the terms of the contract, and that he had sustained damage by reason thereof.
The court below seems to have taken the view that the plaintiff was entitled to his pay as long as the work of the contractor was. done, and that no final certificate was required. It does not seem to me, from a reading of the contract, that this position can he maintained. The. plaintiff, before he can *137recover, must produce the architect’s final certificate, as required by the contract, that the work has been done to his satisfaction.
Another reason why we think the judgment should be reversed is that the guaranty contained in the specifications is an independent undertaking and has nothing to do with the performance of the work, and, at all events, whether the plaintiff had procured the final certificate of the architect or not, it was competent for the defendant to allege and prove that the furnace did not supply the heat which it was agreed it should. ■do by the contractor, and that it would not warm the rooms to which radiation is conducted to seventy degrees Fahrenheit in the coldest winter weather. We think the court erred in ■excluding the testimony which the defendant offered tending to show that the furnace did not perform the work which the plaintiff agreed by his contract that it should do.
The judgment appealed from should, therefore, be set aside and a new trial ordered, with costs to abide the event of the action.
White, J.By the contract between the parties the heating apparatus was to be completed as soon as it reasonably could be, and it was in fact completed prior to December 22, 1892. All the work and material used were satisfactory to the defendant, and the whole price of the apparatus became due and payable on January 22, 1893.
The contract for the work guarantees that the apparatus will warm all rooms to which radiation is set to seventy ' degrees Fahrenheit in the coldest winter weather.
The defendant pleaded, and on the trial offered to prove, a breach of this guaranty. The evidence was> excluded, on the ground that the work and material used in constructing the heating apparatus complied in all respects with the contract, and that, therefore, the plaintiff had performed this guaranty. To be more literally exact, the trial court held that the parties by the contract made the architect an arbiter of the question as to whether the warranty, had been fulfilled by the plaintiff, *138and that the certificate of the architect that all the work had been completed to his satisfaction and in accordance with the contract conclusively establishes the fact of such fulfillment.
I am of the opinion that there is no connection between the certificate of the architect and the guaranty hy the plaintiff. The two things are independent of each other. There is-nothing in the contract by which the architect is called upon, to judge or pass upon the heating capacity of the apparatus j his province is solely that of judge and arbiter between the-parties as to the correspondence of the apparatus in material,, workmanship and structure with the contract. The guaranty in question by the plaintiff has no relation to any of those things, but solely to the ‘ heating capacity of the apparatus. Assuming, then, that a breach of this guaranty is sufficiently pleaded, and that does not appear to he disputed, it follows-that the exclusion of evidence on the part of the 'defendant' in support of his claim for a breach of this guaranty by the plaintiff was error.
That the work and material used in and that the apparatus-corresponded physically in all particulars with the contract is not open to dispute, but whether the apparatus, when completed,'failed' to fulfill the guaranty is, and if it fail in that regard a cause of action for its breach immediately accrues in favor of the defendant.
As the case does not contain all the' evidence, the findings of fact by the trial court are conclusive, but the exclusion of defendant’s evidence in support of his counterclaim for breach of warranty is a question of law and subject to review here.
The’judgment appealed from should be reversed and a new trial ordered, with costs to abide the event.
