I think Boonstra are fantastic and responded to my request for a service call within 24 hours during the heat wave on Tuesday, June 24 when the temp was 36C. Amazing really. Kevin P. was our technician and diagnosed the issue in minutes and completed the repair. He was organized, neat and professional. This company is customer focused and know what they are doing. I wouldn’t do business with anyone else.

Needed our central air fixed....called Boonstra. They came within a day. (Weekend service call)Technician Jimmy was polite and went straight to work. He identified the issue quickly. Fixed it within minutes. The price was affordable and now the temperature in our house is livable again. Thanks Jimmy for fixing the AC on what seemed like the hottest day ever. We would definitely call Boonstra again.

Michael S. from Boonstra was absolutely amazing! He spent the entire afternoon replacing my air conditioning unit. Michael and his companion were incredibly knowledgeable, friendly, and professional and left my place spotless, which I really appreciated. Shout out as well to Jimmy for the accurate and efficient diagnosis, and to Tom the sales rep, who ensured my installation was expedited. Excellent service all around!

We had a great experience with Daniel C. and his install team for our new furnace & AC units. They were fast, knowledgeable, and paid attention to detail. James in sales also helped us greatly with picking the right equipment for our home! Thanks so much!

Every technician that has been sent by Boonstra has been amazing, courteous, friendly and professional. My issue has been with the scheduling department. Our furnace crapped put during the coldest months of the winter and we bought the furnace/air conditioner package. They installed the furnace right away, no issues. Because it was so cold, we advised them they could have the air conditioner installation held off until it was warmer. Scheduling was supposed to call and arrange it, but six months later I hadn’t heard anything. After three phone calls I was finally able to arrange a time for installation. When the technician came, they had advised him it was an air conditioner start up. On an air conditioner that we haven’t received or had installed yet. So here I am still, no new air conditioner (that I have been paying for), and still waiting to hear when I’m going to get one. Not too happy about that.

While the initial technician was unable to rectify the problem, Boonstra has been responsive and working to complete the repair within their stated timeline. An appointment for a senior technician was made and the problem should be resolved within 24 hours. I appreciate that they are working hard to complete the repair quickly and have self-incentivized with the guarantee to provide me with $1000 if my system isn’t fixed within 24 hours (eligibility due to it’s installation being less than a year ago). My experience with Boonstra has always been positive and I am happy to recommend them if you need the services they provide.

Technician was great, I had appliances from 3 different companies, he came and checked the furnace from Boonstra to make sure there was no warranty defects, and showed me the likely issue, which was under warranty from the other equipment provider. Very appreciative of the help. I'd recommend them for any future service and will definitely use them when we replace the older units.

We had another great experience with Boonstra for our new air conditioner from start to finish. They were on-time, friendly and delivered great service. Nolan and Zack were super to deal with and knowledgeable. We are repeat customers and will continue to be!

Andrew investigated our issues and proposed several solutions to solve the problems. Andrew is a straight shooter and his skill and experience got replacement procedures to change our 7! year old mini split ordered and installed in 4 days. Daniel and his partner did a terrific installation. They were Professionals. Skilled, courteous efficient ,fast and they left the worksite perfect including reinstalling the TV, The Boonstra team was Terrific!!!

I had a furnace and air conditioner installed back in Dec. 24. As it was too cold, they said they would have to come back in the warmer weather to start up my air conditioner.
My start-up appointment with Luis F. was very pleasant and informative. He was very knowledgeable and explained everything he was doing, as I had questioned about my furnance as well. Thanks Luis/Boonstra for your services.

Efficient and affordable. Professional and down to earth workers. From the beginning of choosing what was best for my AC needs and buying a new water heater, James sat with me and discussed all the options. Then having Daniel and his crew come the next day to install it all. They were efficient, professional and very knowledgeable. What’s great is that Boonstra uses their own people to come and install. They took everything apart and put everything new in. I recommend Boonstra to anyone who wants a smooth process in buying the best equipment for what you need and having the job done right.

I recently had a new furnace and A/C system installed, and I couldn’t be happier with the experience. The technicians arrived on time, were professional throughout the entire process, and made sure everything was installed correctly. The new system is working great, and they left the space clean and tidy after the job was done. Highly recommend!

I had them complete a duct cleaning for me. Zakkary and Calum (hope i spelt that right) Absolutely amazing guys.. so friendly.. they brought treats for my dog. The work was efficient and the results spectacular. My house literally feels sooo much cleaner. Zakkary shared video and also showed me how much stuff was in my duct work. Its been 17 years since my last duct cleaning. Should be done every five years. If you want excellent service and superior work.. go to Boomstra!!! I'll be back in 5 years!!!

I have Boonstra come out to check our furnace/air conditioner every spring and fall. They have always been very kind, honest and even give good honest opinions. I've never had a bad experience with any of their technicians! This time we had Jimmy. As expected, very curious, polite and thorough.
Great job Boonstra! You've got me for life!!

The technician did a great job working on my furnace and heat pump doing it. It’s yearly check up found some things that needed to be adjusted and I’m all set.

Came as scheduled. Staff were friendly and informative.
Work was completed in a professional and effective manner. Went over the work and explained the set up before signing off.

I had issues with my furnace and Andrew was so efficient and knowledgeable. He got it running in less than 30 minutes.

Even booking the service was very simple and they provide real time tracking so you can have a better idea of when the technician will be there! All in all, 10/10 service 🙂

Called for emergency service about 10:30 as it looked like my thermostat was not operating (after I changed batteries). Boonstra put me on hold to find out if their service rep had a thermostat on board. Jeff arrived a couple of hours later, tested, replaced and demoed the device programs. All was well and house started warming up right away. Very very happy with the service and my rep.
Melissa Sheppard

Really great service from Nolan representing Boonstra. We’ve previously had a heat pump installed from them and this time had a new electric water heater installed. Service was prompt and detailed and we’d been happy to recommend them to anyone needing their services.
