"It's now been about a week since the Bosanac team installed our new air conditioning unit and I can say without a doubt that these are the guys you need to call.

Here's the jist. Our old unit went on the fritz so I called their office. The very nice and knowledgeable receptionist gave me some advise of what to check before requesting a service call which told me right there that Bosanac isn't in the business busy for the cash. Turned out I needed a repair guy who put the time in and did his best to fix the old unit but unfortunately it was toast. BUT, he only charged me for one hour labour and he was there for quite some time longer. So, at this point a new unit it must be. The repairman shook my hand and told me he would send a guy over soon to discuss options. Within 10 minutes (I live around the corner as it turn out) John Bosanac himself was sitting with me discussing our options. And after listening to his "fatherly advice" we had agreed upon an affordable, efficient, suitable unit to be installed within just 2 days. The installers came, were courteous, respectful and thorough and by noon the house was cool again with nearly no trace of an installation team having ever been at my house. Nice job on the clean up guys!

We are loving our new central air system as it is quicker, quieter and most likely much cheaper on hydro than what we were used to. Thank you John Bosanac and a big thanks to your team as well.

HIGHLY RECOMENDING THE BOSANAC TEAM. Competitively affordable, quite respectful, and they certainly get the job done right the first time!"

"John is very responsive, he does not walk away from a project. He also works with you to come up with the best strategy to achieve your goal, rather than cramming a "universal" approach over every situation. Strongly recommended."

"My furnace has never worked better thanks to you.

If you recall, the service man re-wired my boiler and now it working perfectly. It was installed 12 years ago by the Burlington firm, and it was not properly wired.

Cheers and thanks again."

"Thanks again for your call earlier and for all of Allan's patience and hard work. Helen and I have looked at all of the work and are very happy with the result. With regard to the Hydro inspection, next week is extremely busy for us. If it could wait to the following week, it could be scheduled for that Monday (June 23rd). Please let me know if that works. Thanks again and I look forward to recommending you to my friends and neighbours."

"Thanks to your work crew for installing the furnace today! Very happy to have heat!! I was not given any paperwork to sign so please let me know if I need to do that. Many thanks for giving us the opportunity to pay for the furnace in 3 installments. I can put the cheques in the mail or I can be available if you're in the area to pick them up. On Tuesday, I will be in the office after 12 noon. Wednesday, I should be here all day. I look forward to hearing from you."
