See why so many families in Guelph and nearby communities trust Oosterveld Heating and Air Conditioning for fast, professional service. Whether it’s a heating emergency in January, routine AC maintenance in July, or a humidifier installation for better comfort, our customers know they can count on us.
Very patient and kind, and will test every edge case to make sure it’s working perfectly.
We subscribe to their service that includes two heating and air conditioning “checkups” per year. Darius, who did the work this spring was, as all the technicians have been, meticulous, taking notes on part of the system that may be wearing out for any service we might need, and explaining it to us. We appreciate this.
Respectful. Explained what he had done. Cleaned AC unity, swapped filter and made sure AC was in good working order.
Even took used filter with him to dispose of.
I am happy with the service I received.
From the first contact, they were very respectful and quick to respond, explaining everything clearly and professionally.
The work was clean and well done, and they finished on time without any delays 👍
Most importantly, their attitude was very kind and professional, making the whole experience smooth and comfortable from start to finish.
I highly recommend them to anyone looking for reliable work and respectful service 🌟
Called in the morning and Ryan arrived a few hours later ( and not even an emergency call). The level of professionalism was top notch. His inspection was though and reviewed all the details with me. He also had some great recommendations.
Oosterveld will be taking care of all my future needs. Thanks Ryan!
