Until today, I thought furnace (boiler) cleaning was a pretty simple matter and that there was only one way to do it. Apparently, there is a right way and a very wrong way to go about it. For the last 3 cleanings, the carbon monoxide readings were climbing up after each cleaning - from 78 to 82 to 86. This is below critical but indicates a problem that I did not fully understand. The last company that I used took about 20 minutes. They took the burner cover off and vacuumed around a bit and that was it. Every time they did it, I always thought that it was something I could have done myself for free but figured that since they're in business, they must know what they're doing. Wrong!
I finally decided to call another company and chose Leaside because the reviews were more numerous and good.
This was a very good decision and one I wish I had made years ago. The current carbon monoxide reading is 38 so a dramatic and significant drop from the last reading of 86.
Our boiler is 22 years old and the dirt inside it can testify to that. This boiler was never cleaned properly so it all accumulated over the years into the heat exchanger and the exhaust piping through the chimney. The only internal part that did not show 22 years' worth were the burners which had been somewhat cleaned over the years. The core of the boiler is the heat exchanger and it was filthy.
I want to thank Dylan for his patience and for explaining what he was doing and the function of each component (and not minding my looking over his shoulder) and how all the dirt was affecting the furnace. I finally understand how it all works now. What he did makes sense. How it was done by the other company does not.
So as not to frighten anyone about the cost, note that this intensive cleaning does not need to be done every year but if the monoxide readings start to climb up again, it would be very wise to have it done.
Thank you Dylan.

Thanks so much for this review. I'm glad we were able to help you out. With the proper maintenance I'm sure we can keep this boiler going for many more years.
