ESC HVAC Service & Retrofit Division acquired by Carmichael Engineering Limited

To Our Valued customers;

It is with mixed emotions that we write this letter, one of sadness and joy.

In July 1983, I could have never dreamed of the journey that owning our own business would lead us on.

As many of you know, our business has grown in areas that were not even on our radar on that day, when I started the small Air Conditioning Service and Retrofit Company in Alliston. We were following in three generations of the Solomon Family that had worked in he Mechanical and Heating Service since 1924.

Recently our business has grown to include Cleanroom Construction, complete with our own patent pending Cleanroom Wall System, as well as designing and building Custom Environmental Systems for Critical Environments, for projects across North America.

Earlier this year we made the decision that our Air Conditioning Service and Retrofit Division would be better served being part of a larger dedicated Air Conditioning Organization, of which we could only think of one logical choice. We have worked with Carmichael since 1988, and recently on numerous projects in Ontario and Alberta.

It gives us Joy to be able to formally introduce you to:

Carmichael Engineering Inc., who with their new Barrie office has a 17 Office presence in Canada from Coast to Coast. More information about this third generation family business is on the following page.

From your perspective we hope you will not see many changes beside the positive news of being serviced from one of the largest Air Conditioning Service Operations in Canada, with capabilities beyond our dreams.

The phone numbers for service calls will stay the same, locally in Barrie @ 705 722 3220, and across Ontario @ 1 800 461 5477.

Peter Boudreau will be your contact with his mobile numbers 705 796 6360 & 416 677 2306, directly at his office 289 360 1623 or by email @ [email protected]

At ESC we are remaining in the Custom HVAC Manufacturing and Cleanroom Markets, and we can be reached @ our new phone numbers listed below.

Thank you for the opportunity to have been your Service Provider for all of these years. If any questions arise please do not hesitate to contact me at any time.

Sincerely;

Environmental Systems Corporation

Vernon Solomon
