“ I called Kaiser in the morning. They were able to get out the same day to fix the furnace. “
I was happy with their service. When I turned on the forced air unit furnace for the first time this season, the fan wouldn't come on. I called Kaiser in the morning. They were able to get out the same day to fix the furnace. I took the service plan so the Technician also serviced the unit. Price seemed fair. Fast, friendly and efficient.

Since 1996, I’ve chosen them for another installation at my now current home, having been super happy with the first one. They kindly remind me when it’s time for maintenance-which I elected to pay for-and provide excellent service without extra costs if unnecessary. I appreciate their honest and professional service.
