Air Conditioning Installation Matters
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.
Improper air conditioner installations can lead to:
- Reduced cooling performance and energy efficiency
- Louder system operation
- Increased frequency of service calls and breakdowns
- Premature wear and shorter equipment lifespan
At Martino HVAC, we focus on clean, professional installations designed for long-term reliability, performance, and comfort — not shortcuts.
Professional Installation Makes the Difference
Our experienced team takes pride in every installation, ensuring systems are properly designed, installed, and tested for optimal operation. From custom homes to replacement systems, we believe attention to detail matters.
We also work closely with homeowners to explain how their new system operates and help them get the most comfort and efficiency from their investment.

What Our Customers Say - Trusted by homeowners across the GTA and Barrie

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.

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.

10/10 I recommend this company and these Techs any day!
10/10 I recommend this company and these Techs any day!
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.

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.
