We've always used Swiss Air to check our heating and cooling systems at the beginning of every season. The technician was friendly and efficient. He accomplished the tasks and gave us a good rundown on what he checked and serviced.

Bernie, their salesman, gave us a very informed presentation of the Daikin product quality. Daikin also offered the best warranty compared to the other products we received quotes on. Their follow up after the sale was to notch.

Ben and his team were exceptional! We were in dire straits and had a wedding happening on a Saturday afternoon. It was 100° outside and the air conditioner went out. We had 100 people showing up in just a couple hours. Not only did they come in after hours and return multiple times with the correct parts needed, but they went above and beyond to make sure that our guests had air-conditioning! I could not recommend them more! Ben and Dave you guys were unbelievably amazing! These guys will be the first guys I ever call in the future!

The company did everything and was extremely courteous as the workers came in and out of my home at 19 degree weather to install a Air conditioner and new heating unit. They were on time and worked until everything was done. Cleaned up everything to where it didn't even look like they did anything. Very professional company

Their technician was very knowledgeable and did not try to over sell me on anything during my seasonal maintenance appointment. He let me know what could wait and what to look for to know when something is failing so I could contact them to schedule a repair.

Came when expected, very efficient in diagnosing the problem and super friendly. I thought I was at least gonna spend some big money but the tech located some loose wires and fixed it for free. Couldn't be happier with the service and would highly recommend to anyone with a downed HVAC system.

Excellent job in every way. The original tech diagnosis advised us not to try and repair our ac unit .we chose to replace it and he did a great job of scheduling us right away.the salesman was terrific and the financing took maybe 5 minutes..the installers were on time and hard workers with great personalities .we love our new ac/furnace and the price is very competitive.highly recommend!!

We were able to obtain the exact HVAC system we needed at a competitive price and in a turn around time that suited our schedule very well. The installation service was efficient and professional. Since installation, maintenance appointments have been timely. We have experienced no issues with either the furnace or the air conditioner since installation and are very pleased with the company.

I wouldn't ever dream of using anyone else for my HVAC needs. They have been nothing short of amazing for over 12 years. The bottom line is they care about their customers - and everything they do proves it!

I never leave these kind of scores. This company has exceeded every expectation I’ve had. I bought the condo I live in now and found that Swiss Air had installed the HVAC unit. I had never heard of them before, so I thought I’d take a chance On them when a seasonal inspection came due. Wow…. Just Wow! From the initial call to the technician that came, I was amazed!! So courteous, so respectful, so knowledgeable!! Everyone took time with me and explained all things clearly and concisely. I have built and run corporate help desks all my life and this company displays many things I taught my agents. Setting customer expectations is key and this Management Team has it right. I compliment all involved with Swiss Air!!

We have used Swiss Air for many years for our maintenance of our furnace and air conditioning When it came time for us to replace our old HVAC system, it was. A easy decision to chose Swiss Air to do the install. We are very pleased with this system and the service we have been provided. We highly recommend Swiss Air and their staff.

We have worked with Swiss Air for years and they have always been fair and honest with us. Their technicians answer our questions or find out the answers for us if they don’t know right away. They recommend certain maintenance issues but don’t pressure us into anything that doesn’t need to be done right away. It makes us feel like they care about the customer and not just a sell. Keep up the good work Swiss Air!

James & Katie Welch

The office will make sure you’re aware of when your appointment is and will update you on the whereabouts of the technician. The technician will call and let you know they’re on their way. They are cordial and get right down to work. The technician is mindful of your floors and will wear slip on covers over their shoes. After they’re done they walk you through all the work they did and let you know the status of your furnace or ac. I’ve been a Swiss air customer since 2005 or so and never had any issues with the service.

They showed up at the end of a very hot day and got to work right away on an A/C issue. They listened to my concerns and addressed all of my issues. They also inspected the furnace and pointed out possible problems. This helped me to plan for future repairs or replacement of furnace. They also suggested a better filter to use so that the air would be cleaner.

Swiss Air was a life saver. After more than 25 years, our AC unit went out in the middle of very high temps. Levi answered my call and asked Allen Parker to visit my home that morning. It was amazing. And the new Daikon was installed within two days. The crew was great! And … I received 0% financing. What could have been a crisis turned out to be a wonderful experience. I hope to be working with Swiss Air from now on:

Replaced our old hvac systems in our house after we moved in. Swiss Air was the company we used to do the work. The installers were great. Work done quickly and left everything clean. Very happy with the systems installed. Also use Swiss Air for our yearly maintenance and any service needed. Always easy to schedule. Very nice people and they spend time answering questions we might have.

Swiss Air technician did a thorough pre-buy inspection of the HVAC system and provided a detailed list of findings & recommendations. The was an as-is residential contract so it was important to us to have a thorough inspection and Swiss Air provided just that.

We just bought a home here in Oakville and were in need of a new unit as the one that was here was shot. The presentation on the new Swiss Air unit given to us was fantastic and we were sold on it immediately! It is working beautifully, just like he said it would. We would highly recommend Swiss Air to anyone!
