Great experience with John from Swiss Air Heating & Cooling! He defined and installed the basement vents perfectly, keeping airflow and layout in mind. Super professional, quick, and easy to work with. First step of our basement project done right—highly recommend!!

We called Swiss Air to repair a leak in our gas lines. Our technician, John, was great to work with. He was friendly and personable, explained what needed to be done, and fixed the problem quickly. He also arrived within an hour or two of us calling. Overall, the experience was great, the price was reasonable, and the work was done well. We'll definitely call Swiss Air again if we need help in the future.

Fast response, excellent gas line repair, and professional service. We discovered a leak in our main gas line earlier this week and had to shut off the gas, which meant no heat during the cold weather. I called several HVAC contractors in the O'Fallon area hoping someone could come out the same day for a gas line repair, but most weren’t available for days. When I called Swiss Air and spoke with Rachel, she told me they could send a technician that very morning. She was friendly, understanding, and very professional. The technician arrived earlier than expected, completed the repair quickly, and the price was very reasonable. If you need HVAC or gas line repair service, I highly recommend Swiss Air. We’ll definitely call them again for any future heating or cooling needs.

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!

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!!

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.

The Swiss Air technician was very knowledgeable and professional. He found the problem quickly and showed me the burn area in the panel that needed to be replaced. My thermostat was also not functioning properly. He was able to replace that immediately.

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!
