The person who came to inspect the air conditioning knows what he was doing. He was very methodical and went through the unit to identify issues with my air conditioning unit.

I had a sales representative come on Saturday morning who was very informative and detailed. They came to install Monday morning, and we had a new AC, furnace, and thermostat in by the end of the day. Everyone from Oosterveld were efficient , respectful, and have great competitive prices. Great communication across the board and I would highly recommend to anyone else.

I have had a great experience with Oosterveld. They come and service my furnace and air conditioner every year. This puts my mind at ease as I head into the seasons. The company has always been more then accommodating. All the fellows that have come to do the services have been knowledgeable and fun to work with. Thank you Oosterveld for all your hard work and professionalism.

Needed service quickly on AC. Phoned late in the evening to book an appointment, actually spoke to a live person in service (noAI). Scheduled the appointment for following day. Ryan arrived on time, was pleasant, informative, and clear relative to repairs and costs. Cooling now. Thanks

We had our Heat/AC system installed last winter, and it has been running flawlessly through all the seasons.The sales representative ‘Abe’ was exceptional. He took the time to clearly explain all the services, fees, and general charges so there were no surprises.
He also recommended an excellent connection method from our basement panel box that worked out perfectly.
The installation crew ‘Rana & Sunny’ weee also amazing—very professional and did a fantastic job. I am extremely happy with the service and highly recommend this company!

Dave B did the annual maintenance of my AC. He obviously is very knowledgeable of his job as he was very thorough in inspecting and maintaining tha ac.He explained in detail the equipment status and performance. He checked the electrical, refrigerant pressure and temperature. He observed the mess and damage in the floor as a result of the various drain tubes of other equipments lumped in the floor drain. He recommended to put drain lines directly into floor drain to prevent water damage.

Wonderful firm and people. We have dealt with them ever since they made an emergency repair to our furnace several years ago when it’s original installer wouldn’t come out.
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.
