Air Conditioning Installation Matters
DID YOU KNOW?
Top sample: Brazed with nitrogen - the inside of the copper line stays clean.
Bottom sample: Brazed without nitrogen - black oxidation forms inside the pipe and can contaminate the system.
Your air conditioner may look great from the outside but what does the installation look like on the inside?
Proper installation plays a major role in the performance, efficiency, reliability, and lifespan of your cooling system. Unfortunately, low-cost or rushed installations can leave debris and contamination inside the refrigerant lines from Day 1, leading to problems that may not be immediately visible to the homeowner.

They’re not honest.
They intentionally install faulty units, then glue it together when it eventually breaks. They also don’t disclose what the issue is or how they fixed it. Every time we call in for a repair they temporarily glue it together and say everythings fine.
When the warranty runs out they refuse to show up or answer calls. We hired a different technician to take a look and they explained what martino HVAC has been doing. We had to completely replace the unit.

I wanted to recognize the outstanding service we received from Peter. He was professional, knowledgeable, and incredibly helpful throughout the entire visit. He quickly diagnosed the issues with our AC system and fixed every problem we were experiencing. Peter provided fantastic customer service, explained everything clearly, and made sure the job was done right. We truly appreciate his hard work and would highly recommend him to anyone needing HVAC service. Thank you, Peter, for an excellent experience!

Very disappointing after-sales service.
Martino installed our HVAC system under 5 years ago, so when we had an issue with warrantied equipment, we naturally contacted them expecting support. Instead, we spent days chasing them with calls and emails and could not get a timely response.
This was during a stretch of hot weather, with very young kids in the house. That should not be the kind of situation where a customer has to repeatedly follow up just to get someone to acknowledge the issue.
When we finally reached someone, the answer was essentially that we were outside their service area and they could not assist us. That may be their policy, but it is very hard to understand how a company can install a system and then, when a warranty issue arises, say the customer is outside the area they are willing to service.
The biggest issue for me was the lack of ownership. No prompt response, no practical solution, no meaningful help. Just a lot of chasing and a deeply unsatisfactory answer.
I would not use Martino again.

We had a very frustrating experience with Martino HVAC.
Martino installed our HVAC system in 2023. When we noticed an issue with warrantied products, we reached out to them for assistance. Despite multiple calls and follow-ups over the course of a week, we received no response. This was especially stressful given that we have a newborn and a toddler at home, and the weather was very hot at the time.
After repeated calls, I eventually managed to reach someone the following week. At that point, we were told that we were outside their service/catchment area and that they could not do anything to help us.
Given that Martino installed the system and the issue involved warrantied products, the lack of communication and ultimate refusal to assist was extremely disappointing. I would not recommend them based on this experience.

Martino installed the HVAC at my new construction rental unit in Kitchener. They came out twice last summer for my AC, not cooling and tripping my breaker. They installed a hard start kit, $400 later, but they did not fix the problem.
Come this season, AC is still not cooling, so I called a local service company, diagnosed the issue saying hot water was still going to the heat pump and circulating warm air. Probably was making my AC work overtime and tripping the breaker; must be a broken stuck zone valve. So perhaps it was poor installation but this type of stuff shouldn’t be failing after 3 years and should have been diagnosed properly on the first tech. visit.

I’ve avoided leaving a public review for MARTINO HVAC for a long time because I genuinely wanted to give them the opportunity to make things right. Unfortunately, after years (3 years to be exact) of ongoing issues, ignored follow-ups, and unfinished work, I’ve had enough.
Since moving into our brand new build, we have had nothing but problems with this company which I have offered multiple times to have the issues resolved.
* AC units needing service within 3 days of possession
* Fireplace face frames took 2 years to come in
* Gas hoses not hooked up properly on our heaters outside
* Outdoor heaters that have NEVER worked properly
* An outdoor pizza oven that still does not light properly
Last August 2025, someone finally came out to inspect the outdoor heaters and told us a part was being ordered. We never received a follow-up call for installation and have heard nothing since then despite being told multiple times the parts are on order.
To make matters worse, earlier in the year their technician had to spend over 5 hours at our home redoing the work because the original installation was not completed correctly.
The only positive experience throughout all of this has been Jamie at reception. She consistently tried her best to help us, and I truly commend her professionalism and effort. Unfortunately, despite her attempts, we were continually met with excuses and no actual resolution. At no fault of hers, it falls in the hands of those responsible to see the work thru.
Peter their tech has also been a saint, and wonderful to deal with, he was the one who got us back in order and working! He is a real gem!
This company was chosen by our builder, and sadly they have turned out to be like many contractors who get paid and disappear afterward, don’t stand behind their work and show little to no interest in standing behind their installations.
For the amount of money spent on these systems and installations, the level of service, communication, and integrity has been beyond disappointing.
I would not recommend MARTINO HVAC based on our experience.

I have used Martino since 2011 with no issues – professional service and I have always had a great technician.
In February 2026 C, a Martino employee, contacted me to book my annual furnace cleaning and we booked for February 26. Nobody showed up, no phone call, nothing. When I was able to get hold of C he told me that I was suddenly no longer in Martino’s service area. I was shocked that there was no communication and that they would just drop me with no warning.
Last week I was contacted by J, a Martino employee, to once again book my annual furnace cleaning. I explained what happened last time when C contacted me. J checked and confirmed that I am off their client list – no warning, no recommendations for a new company to service my heating and cooling equipment, nothing.
If you are a loyal customer, be aware that this could potentially happen to you. I really thought I was set for life with a great company. I am beyond disappointed at being so unprofessionally kicked to the curb like this, do better Martino.

My furnace died. Outside temperature was freezing. My house dropped to 16°C. I have two kids under 15. We slept under three blankets waiting for a callback that never came.
Martino Heating had stickers with their name, phone number, and “24/7 emergency service” plastered all over my furnace, my filter box, and even my ductwork. You would have thought they sponsored the unit or owned it.
I was already an existing customer. They had serviced my furnace and air conditioner before.
I called their emergency line. They asked for my name, address, phone number, and email — strange, given I was already in their system.
When I said I was in Caledon, they asked me how to spell it. They are in Vaughan. The next city over.
They assured me someone would call back to schedule emergency service.
That was the last I ever heard from them. It has been over five days. No callback. No service. No explanation.
If you enjoy being ignored while your family freezes, by all means, call Martino. Otherwise, save yourself the frustration and hire literally any other HVAC company in the GTA.
Unprofessional and useless.

Great experience dealing with Martino HVAC in Barrie. We had some furnace issues and Peter was able to troubleshoot with us over the phone. The issue persisted so he came to our house and followed up with us after the fact to ensure everything was working properly. The customer service, communication, and attention to detail is unmatched! We have nothing but amazing things to say about Peter and Martino HVAC. Very happy to be customers and have the membership with the company. Thanks for everything, Peter!

It is really frustrating to new furnace stops every within weeks, and have to place a service call every 3-4 weeks.
Only response i receive is will pass your message to technician . If you ask when they can come or call , response – “we don’t know” 2 times we had to stay without heat at home because “technician didn’t call” “no technician available “. Again called and asked same response we dont know when they call or come we passed your message.
I requested and called during office hours as well and asked to contact manager or any senior representative . Response- we will pass your message manager will call you its days now after the call as well and no callback from manager or any follow ups and the furnace stopped again.
Response to below reply- phone you already have as well the address . Calls were scheduled already, the technicians texted and said they cannot make it and will call tomorrow. In morning they say if still needed them have to book call again by call same number !!

I called Martino after I had another company come out and tell me my boiler was dead and quote me what I know was well over market rate for a new one. Martino sent Peter, who arrived on time, gave great communication and went above and beyond to see if he could bring the old boiler back to life and he was able to repair it! After the service, he researched and found where I can purchase parts in the future and followed up with me to help make a plan going forward for my boiler. Can’t recommend these guys enough!!

Our furnace stopped working Sunday the night before family day. I called Martino’s first thing ion the holiday morning was greeted with a friendly lady she took my information and said someone would call me. A short while later I was contacted and told he would be out between 10 or 11 am. He arrived 20 minutes early and after a short while we heard the furnace start up. He then proceeded to check other things just to make sure everything else was fine. It was sure nice to have heat again.

I had a meeting with Martino’s HVAC this morning to understand the functionality of the heating system installed at my newly built house. Thanks to Aryan, who answered all my questions in detail. He was very professional, knowledgeable and friendly. He walked me through the entire system and explained how it works. I was not happy with the low furnace air flow coming through the vents. He fixed it. Once again, thanks, Aryan.

I had Martino HVAC come out to service and troubleshoot my furnace when I had no heat during a very cold February evening. The technicians arrived in a very reasonable amount of time, even though it was close to midnight. I really appreciated both the call takers and the technicians for being responsive, professional, and helpful. Great customer service when it mattered most. Highly recommend.

I just recently hired Martino’s HVAC to maintain and clean my two gas furnaces, air conditioner and fireplace in my home. I know and respect the Martino family. Jamie, the person that I made the arrangements with, was fantastic to deal with and made the arrangements quickly and easy for me. The technician, Bob, showed up this morning promptly as arranged. He was very professional, friendly, knowledgeable and worked efficiently. He answered my many questions about my home’s efficency. I am very happy with my decision to switch over to Martino’s. I am confident that the comfort and safety of my home is in good hands.

Honest, upfront, and incredibly knowledgeable. Martino installed ame maintained our tankless system and furnace in our last home. They service all our friends and family and have been a huge asset in getting the existing system in our new home tuned up and working like a dream. Every tech has been awesome but Kyle is THE BEST and is an absolute expert with radiant in floor and boiler systems. 100% recommend

Tod and Gary came by to complete an AC installation and these guys were amazing. They were very clean, respectful, and took the time to answer my questions. They made sure to keep me informed of the situation at hand and made sure everything was up and running properly before heading out.
10/10 I recommend this company and these Techs any day!

**Update: Today, I got a call from this company, and just like other homeowners have mentioned, they said they don’t have me in their files and insisted I pay $175 for a diagnostic service. Last year, my A/C stopped working, and after investigating, we found out that they had installed a lower AMP breaker.
I don’t trust that this company employs licensed technicians, and their products are clearly subpar.
My house and its furnace, both about 4 years old, came from this company. About 8 months ago, the furnace stopped working but inexplicably started again the next morning before I could call a technician. It failed again around 10 pm tonight. With the heat outside, having a non-functioning furnace is unbearable. I called the emergency line, and the operator demanded $225 plus a diagnostic fee.
I am extremely disappointed that Countrywide associates themselves with such a subpar company. Their product didn’t even last 4 years, let alone the standard 15 years. If you’re considering buying a furnace from this company, think again. For the same or a lower price, you can get a Carrier or Lennox furnace, which are much more reliable and will definitely last more than 4 years. Save yourself the hassle and money by avoiding this company altogether. The operator was so ashamed that she only disclosed her ID number 424, not her name.
I wonder how they got 4.8 google review with such an unreliable product.

We found a water leak and turned off the AC right away. I called the office in the morning, and a technician came the next day for regular yearly maintenance (for a fee) and an AC tune-up. He said everything was okay. However, at night, we discovered the water leak again and had to turn off the AC again, despite the heat as we wanted to avoid causing any further damage.
Another technician arrived and found that the drip pan was rusted and leaking. We then had to wait almost a week for the third technician to come and replace the drip pan. Although the job was finally completed, the quality of the work was poor. We had to add tape all around and straighten the cover ourselves, which we only noticed after the technician had left.
We were satisfied with this company in the past, and we hope this is just a single incident.

It has been truly a pleasure being a customer of Martino. I am very happy with the service I’ve received and I am particularly impressed with the knowledge of Yezdi. He is very experienced, takes the time to explain everything in great detail and shares helpful tips during the service. I always look forward to having him service my HVAC equipment.
I also appreciate the pricing of the service plans. It is reasonable and takes away the stress of servicing our HVAC equipment, as well as insuring pricey repairs.
The service department is responsive and accommodating. Overall a professional and A++ experience all around
