The installation team is fantastic.on time, kind, professional, clean. The experience was completely stress-free! Great job!

Thanks to the help and guidance of Joseph Shenouda and the team at Guaranteed Industries, our conversion from oil to electric furnace was smooth and, dare I say, totally uneventful. From the start of the process, Joseph was thorough and professional in his approach and remained quick to respond to my questions throughout. On the day of the conversion, the conversion team was equally professional and it was reassuring to quickly see that they are pro's - their experience and competency was evident. Thank you all, it was a pleasure working with you

During the process of purchasing the unit I was in contact with Peter which was very professional and knowledgeable. As for the installation, the crew was great. Very happy with the service.

I have used Guaranteed Industries many times over the last 40 years but this latest installation was just fantastic. They took out my old oil furnace and the huge oil tank then installed a beautiful new electric furnace (see photo if I’m able to upload it) it. They arrived before 8am and had finished the whole job before 3pm. The salesman was very knowledgeable, polite and helpful. The workers (all 6 of them) were quiet, efficient and did not disrupt my day. I was even able to stay home (upstairs) for the whole day. The price was competitive but their reliability and professionalism puts them way above all the other companies I’ve hired for work on my house. I recommend this company while-heartedly.

Having had a poor ACDuct installation in a fairly complicated new AC setup on a heritage residential detached home that was very poorly done by another contractor. We tried pursuing remedial work thru them without any success we turned to Guaranteed Industries. They were very responsive in carrying out the corrective work. This work involved several visits to the house to analyse and engineer a install new ducting. The management and their team were professional and got the job done. I wouldn’t hesitate to call on them I was extremely impressed by their performance.

Spent $8,278 on a Panasonic ductless system in 2015
In 2019 reported low freon and possible leak after a renovation
2019 - maintenance contract initiated for $638 per year for 4 years.
2019 - service call in addition to maintenance contract $535
2020 - second payment of $638: The service call was not adequate and not what I paid for. The indoor units were not checked, oiled & cleaned, as my contract states. The technician only cleaned the filters, something I do myself every year before starting the system. See the attached photo of the living room unit, which is covered with mold. The outdoor unit was cleaned with my hose. I don't know what was checked in terms of pressure or levels of refrigerant, they do not blow cold.
2020 - a deep clean was performed for additional $$$, plus more freon $$$ - never checked for leaks in the unit during cleaning.
2021 - maintenance contract cancelled for breach of agreement.
2022 - No gas in the system. Called for service and left message that was ignored. Ready to toss this and use a more reliable service.

It was great to work with Guaranteed Industries! Their team was very professional and the job was done quickly and efficiently. I had a new heating system installed, duct work and duct cleaning, all of which I am very pleased with.
06 March 2022 18:51
The installation of a new humidification system was well researched & explained. The technicians were professional, on time and extremely courteous.
28 February 2022 10:57
In 2018 I had my first experience with Peter, very bright guy who knew the business well. He was professional and not pushy and listed all my options and was very patient. Fast forward to 2022 l had an issue with my unit and despite it being 4 years later he responded promptly and within a weeks time I am expecting my unit to be replaced. Peter and Guaranteed are a customer first company, this is the only HVAC company I will do business with in Montreal.

We really appreciated the prompt service, even during this difficult covid period. The staff was professional from A to Z. Courteous and efficient. We are very happy with the 2 AC units that were installed. The company was recommended to us by neighbours and we would recommend it to others as well.
21 October 2021 19:20
Quotation and explanation of options was prompt and extremely thorough. Scheduled installation was on-time and as predicted. Installation crew was extremely competent, tidy, and did not leave until everything was tested and approved. Very satisfied!
05 September 2021 14:07
Excellent service, excellent job, staff was very friendly, answered all questions and very professional. Strongly recommended.

10 years ago I had a new air conditioning unit installed by another company. They told me the best way to install the unit was to brace the unit to the outside of the wall which also happens to be our den on the inside. For 10 long years I endured the constant vibrations and hissing of the unit every time it would go on. I called Guaranteed and they suggested placing the unit on the ground. They quoted me a price which was very fair. The work was scheduled and executed within a few days and my first impression was with the installation. It just looked right. As far as the noise level it had disappeared. Only if you really listen for it can you notice it. What a difference. Their staff was on time, courteous and professional. What else could you ask for?
17 July 2021 7:00
Very professional. The sales contact, Richard, showed up during the installation to make sure everything was satisfactory. They met a few obstacles during the installation but worked them through to my liking.
16 July 2021 23:54
Our Guaranteed Industries representative responded to our e-mails within minutes with answers to any questions or concerns that we had. We had ductless A/C installed, one unit on each floor and the main unit outside. The crew arrived at 7: 30 am (as scheduled) and were finished by 10: 30 am. The workers were knowledgeable, efficient, professional, and completely cleaned up every step of the way. We could not have been more pleased with our having chosen Guaranteed Industries to work with and would highly recommend them.
16 July 2021 11:43
A very professional company. The technician guy (Peter) came in to do the analysis and proposed / suggested the best location and machine that suits my condo. The installation of the A/C was on time. I didn't have to wait for months. The finishing was very good. Their support team is very responsive. I didn't face any issue. I highly recommend it. We might consider them to do the maintenance of our Ventilation system in the building as well. Costco chosen to work with them for a reason!
02 July 2021 22:49
Guaranteed Industries was the most professional and punctual out of all of the HVAC companies that I got in touch with. As we live in an older home, replacing our old AC was a little less than straightforward, and this company was happy to step up to the job. I'm very happy with the new AC installation, especially with the heat and humidity recently! I would recommend.
09 February 2021 14:09
We recently discussed and ordered a steam injection humidifier for our home.after receiving a very competitive quote we pulled the trigger and went ahead with the order. As the furnaces started, i requested the install to be done asap.i was advised it would be about two weeks to receive the machine from the manufacturer.in just a few days, i received a call that they are ready to install, (i believe the couriered it to accommodate our wishes) when the installers showed, up they came with all parts needed.no running back to the shop to pick up something.they came on our schedule and was completed in no time.neat and cleaned up, no garbage left behind.they fully respected covid protocol.we were even pleased that they had special clean covers they placed on their steel work boots when they came into my home. Great team.thank you.

Message à Richard Shapiro

Bonjour Richard,
L’équipe de Mohamed a fait un excellent travail pour l’installation de la nouvelle thermopompe et je voulais t’en aviser. L’ajustement du support protecteur pour la thermopompe a été modifié parfaitement par Sebastien qui est très talentueux.
Finalement, je voulais te remercier pour l’excellent service que tu nous a donné dès le premier jour jusqu’à aujourd’hui en nous donnant « l’heure juste » en tout temps. Toi et ta compagnie, vous vous démarquez de votre compétition!
Merci
Claude H.

I can't say enough about Richard Shapiro and Guaranteed Industries. Our aged AC system had failed. It used a high velocity system that is rarely used today. Several other vendors came to do the job but after seeing our system, determined they could not supply a similar equipment. Then came Richard Shapiro and Guaranteed Industries. They quoted, they got the necessary equipment, and got the job done as promised. I am one very satisfied customer!
28 November 2020 14:47
Richard and Joseph from Garanties Industries were professional and helpful. Service was excellent. From quotation, to keeping us up to date, to execution-well done. I would recommend without hesitiation.
15 November 2020 7:39
The team of two technicians did an excellent job on the conversion of my oil fired furnace and A/C combo into a fully electric Lennox furnace plus heat pump. They were very skilled and knowledgeable, and they patiently explained each major step to me and helped me understand how the new system is intended to function. Above all they kept the work area tidy and organized. The entire conversion, including the removal of the oil tank from the crawl space by a dedicated tank removal team, was done in one day. I am impressed with the outcome and I would fully recommend Guaranteed Industries without any reservations.

This company went above and beyond to rush the installation of a new AC unit at my 80 year old mom's condo, immediately before she was scheduled to start chemotherapy. It was crucial that she be comfortable at home during her treatment and every other company that we called was unresponsive and unreliable. It was the busiest time of year for AC companies in Montreal, but Industries Garanties not only got the very involved job completed in time, but all the workers were professional and competent and Richard was incredibly responsive to all of our many questions. We are very grateful and highly recommend this company.

After a long and painful summer with a broken AC and dealing with various HVAC companies that are either incompetent or never follow up, Guaranteed made it happen. It wasn't a simple task given that the current piping needed to be replaced and re-routed within a strangely designed condo building but the professionalism, timely responsiveness and technical knowledge of this team made it all worthwhile. The commercial side (Peter) was very acute, flexible and supportive while the technicians were super dedicated and a pleasure to work with. I have total confidence in this company and with this current environment where HVAC companies have too much demand to care about customer service, better to pay a little premium and get proper attention instead of sitting around without AC to save a few bucks. Not a surprise COSTCO which has such strict quality standards uses Guaranteed as an HVAC contractor
08 April 2020 21:29
Nous avons beaucoup regretté d'avoir fait confiance à Peter. Nous avons eu plus de 1000$ de frais supplémentaires pour finir l'installation. Peter pose les appareils aux murs et dehors mais tout le reste doit être fait en extra: coffrage des tuyaux, trous dans les murs, tuyaux d'évacuation, installation électrique.rien n'est inclus.
Sans compter les cartes cadeaux Costco promises qui ne sont payés que partiellement.
28 March 2020 3:08
Great fast service, professional work, polite employees, every thing done to what in the contract
08 February 2020 2:12
This company is all you need for your HVAC work. They go above and beyond your expectations and make sure that you're happy, even after the installation. Peter is very honest and knows what he's talking about. He recommended only what we needed and not more. The installation was done very fast and clean. I'll be honest: you may pay slightly more than with other companies, but it's well deserved. Give them a try, you won't regret it.
15 January 2020 12:52
Great service. The technicians did a great job installing the HVAC and it was more affordable than the competition. Peter is a great guy and just a phone call away if you need any help.
13 December 2019 22:53
The Guaranteed Industries team were knowledgeable, polite, experienced, efficient and very pleasant to deal with. Peter Shapiro's informative recommendations and many possible options allowed me to choose what was best for my situation. I am a very satisfied customer.
25 November 2019 1:58
Thank you Peter. I cannot believe it. You are the first company I deal with with such fast (1 hour after my call) and professional support.
18 November 2019 20:01
I phoned 3 companies and asked for a quote to install a Split Air Conditioning System in my home. Peter Shapiro from Guaranteed Industries was the first to offer a quote.

He inspected my house and suggested 3 different options.
His quotes were competitive… but (unfortunately for me) I went with another company.
If I’d only known then, what I know today!
After my installation, I reread the fine print of all the quotes… and realize Guaranteed Industries offer was much better.

Four months later my system (installed by another firm) still wasn’t working properly.
Out of frustration I phoned Peter Shapiro for advice. The next day he inspected my AC system (at no charge) and showed me it’s installation flaws… and explain how his company would have done things differently.
My advice… go with Guaranteed Industries.
15 October 2019 16:56
I'm very happy with my experience from beginning to end for the installation of 2 new electric furnaces with Guaranteed Industries. The team worked great together from removing my old oil furnaces and tanks, all new electrical work and installation of 2 new furnaces in a well times manner. Thanks Peter for the the great service and support in understandng my needs and budget constraints.
15 October 2019 1:40
Richard and his team were wonderful to work with. They are incredibly professional, left the place clean after the installation was completed, and overall had great customer care. Highly recommend them for your A/C needs.
10 October 2019 13:50
Excellent Service, Thank you Peter and your team for the excellent work. You made my summer and hopefully you will make my winter
06 October 2019 16:11
Richard's team did a great job on the installation. Showed up on time, friendly, courteous and clean team. Job was done in the time expected and left us with a great AC installed. Would recommend!
17 September 2019 12:49
Nous sommes très satisfaits de notre installation de thermopompe avec Industries Garanties. Le service est et a été impeccable. Peter et son équipe répondent rapidement à nos demandes et à nos questionnements. J’avoue que notre installation a amélioré notre qualité de vie et notre confort, nous permettant, par exemple, de faire des cuissons au four, durant les jours de canicule, ce que nous ne pouvions faire auparavant tellement la température dans la maison était élevée. Merci
10 September 2019 15:19
Outstanding communication throughout and truly professional service from start to finish. Highly recommended!
04 September 2019 3:24
Service défectueux. Le vendeur te dit une chose, l'installateur une autre et le service d'après vente une autre chose.
03 September 2019 14:48
We dealt with Peter and he was extremely professional, knowledgeable, and patient. We couldn’t be happier with our initial visit with him and we look forward to dealing with Peter in the future.

Très bon service all around. Plusieurs autres compagnies ne répondaient pas à l'appel. Guaranteed Industries a été rapide et excellent. L'analyse des besoins a été bien fait et l'installation fut prompte.
22 August 2019 21:39
I recently had a wall mount air conditioner installed and I have to say, the service from start to finish was excellent. The installation was done as planned and went very smooth. Very professional sales person and installation team! Would highly recommend.
20 August 2019 22:49
Excellent advice, attention, and service from Richard.
Installers were also very efficient and professional.
19 August 2019 3:18
J'ai acheté une thermopompe murale en juillet 2019 et j'ai reçu un excellent service du début à la fin! Peter a pris le temps de bien m'expliquer les différents systèmes et m'a aidé à choisir le meilleur produit qui répond à mes besoins. Après la signature du contrat, il est resté très disponible pour répondre à toutes mes questions et préoccupations. De plus, l'équipe d'installation était très professionnelle et sympathique. Je recommande vivement cette compagnie.
15 August 2019 1:20
Guaranteed Industries is highly recommended! Peter Shapiro was amazing. He took care of us throughout the entire experience. He was always available either in person or by phone. Took the time to explain everything and made sure we understood. A great experience from beginning to the end. The technicians were excellent. In fact dealing with Peter and his entire team was a pleasure. Can't say enough good things about them. Thank you!
09 August 2019 17:51
Peter and his team did an amazing job. I met with several other contractors regarding this installation, and only Peter and his team were able to provide a suitable solution for my cooling situation. Honest, not over promising, and highly capable - I highly recommend Peter and Guaranteed Industries. If I could give 10 stars, I would.
05 August 2019 20:34
Peter and his team are very professional. They did an amazing job installing my A/C. Peter was always there to answer my questions from day 1 to after the installation. He is always available. This is great customer services.
02 August 2019 22:04
Nous sommes heureux d’avoir choisi ce produit de climatisation avec l’aide de Peter. La qualité de l’installation à l’extérieur comme à l’intérieur est excellente.
30 July 2019 9:45
Ils ont des ingénieurs très professionnels. Le personnel est très sympa. Après leur installation, la zone de travail a été nettoyée très proprement. La machine fonctionne à faible bruit. Et il y a des explications détaillées sur l'utilisation. Compagnie très recommandée! Merci à Richard et à son équipe!
20 July 2019 17:44
Having my new a/c system well-installed over a month ago, I called Peter Shapiro to have him show me how to clean my filter. He responded quickly and came by the next day to show me how easy it was to do. Not only was he very pleasant, his quick response demonstrated the quality service he provides and of Guaranteed Industries.
01 February 2019 3:08
Russel and his team came to install a wall unit A/C and it was done exactly the way i wanted. They were both extremely professional and the end result was perfect. Thank you guys for your professionalism.
