Had a few experiences with Hargrave the last couple of weeks while figuring out my AC needs. They were extremely professional, knowledgeable and helpful. Highly recommend them if you’re ever looking for heating and air conditioning experts.

I had three technicians from other companies come to analyze my air conditioning problem and non could figure out the issue. Hargrave’s technician identified the problem right away. Unfortunately I didn’t call them at the onset.

The team was great and efficient in installing the AC, and they were very responsible in making sure the area was cleaned up after installation. The main technician was patient in explaining and answering my questions. Thank you for the Hargrave team. I also enrolled in their Iron Shield plan to ensure my AC and Furnace are working year-round. Great job.

Came through twice in very time sensitive situations. I had no hot water in April due to a tank failure. Enercare and others said a replacement tank would never fit. Kevin assessed the situation and sent his team to install a new hot water tank. My AC failed on Canada Day and the next day Ian went into a very hot attic to get my house cool again.

The technicians introduced themselves, placed carpets down, explained what they were going to do. Worked efficiently, removed all excess materials and garbage. Cleaned up and then patiently showed us how to use the panels. I felt confident with their knowledge and the installation went smoothly.
