What Homeowners Say About Boonstra’s HVAC Services

I had a major breakdown of my furnace/AC unit, (caused by a plugged filter). I called a few companies for help and none of them could send anyone for at least 4 days. I called Boonstra and they sent someone the next day. It was a large repair, so he had to order parts, someone else came the next business day to make the repair. Every person that I dealt with at Boonstra has been polite, friendly and eager to get the job done as quickly as possible. There were no hidden costs and I have come away from this experience knowing I will always call Boonstra first.“​

I came home from a funeral, it’s Friday 3:30pm, 32 degrees and muggy. The AC is dead. I call Boonstra, and they have a tech out to my place by 7:30pm. It’s Adrian’s last call of the day and he’s tired and hot, but he does an A+ job, doesn’t rush through it, and re-fixes the AC when the original part he installed wasn’t working properly. I recommend Boonstra for fast, professional service!“​

What Homeowners Say About Us

“The technician who came to service my furnace was polite and very thorough. I was expecting to just have a filter installed but he double checked to make sure the airflow and furnace was in tiptop shape. He even peeked at my AC unit quickly as he was leaving to let me know it should be cleaned! Super great service as always.“​
