Marlene Kendall – Office Assistant

Marlene is everyone’s favorite co worker she has an amazing ability to bring a smile to your face because she always has one on hers. Marlene is retired ( I know it is hard to believe) and wanted a part time job . Which is basically a full time job for most people , she is our custodian and much more.

When she isn’t at Don’s she is usually with one or more of her 7 grand children.

Ryan George – Lead Service Technician/Gas Fitter 2

Ryan started working at Don’s Heating in 2008. Starting as an Install Helper, Ryan worked his way up in the company to become our Head Service Technician. If you have had service done by Don’s Heating and Cooling, you have most likely met Ryan already. Ryan often works long hours as one of our ‘on-call’ technicians so that our customers will not go without heating or air conditioning if they have an emergency. Feel free to thank Ryan for his hard work & dedication to our customers the next time he’s servicing your equipment.

Tyler Baird – Service Technician/Gas Fitter 2

Tyler is one of our millennials , he has been with us for 4 years and came to us with no experience. We brought him in under our wing and he has proven to be a great asset to our organization. He is a licences gas fitter 2 and a refrigeration/ac apprentice. Customers enjoy his smiling face and his unbelievable knowledge of the trade (he is a born natural) . He claims his favorite hobbies is learning more about his trade which he does by reading and on-line courses.

Bryan Benson – Service Technician/GasFitter 2

What can I say about Bryan , he started with Don’s while he was still in High School on a co-op program.  He eventually came on as a full time employee and started working his way to become a gas fitter 2 which he did complete. After a few years Bryan decided to leave for greener pastures , however after a short time out realized we were the greener pasture. We were all so pleased when Bryan came back home. He is now our certified furnace and air conditioning maintenance person and has started his residential a/c apprenticeship. Bryan receives compliments all the time from our customers and once you meet him you will truly understand why. When he is not at work he spends his time playing hockey or being with his wife and infant daughter.

Chris Simms – Service Technician/Gas Fitter 2

Chris is our newest employee.  He came to us thru a co-op program from Hi-Mark and impressed us so much that we didn’t let him leave.  He is a licensed gas fitter 2 and will soon be starting his a/c apprenticeship. He quickly moved from a helper to being a service technician and although is relatively new at this just has the natural mechanical ability to be an excellent service technician. He loves to learn which is obvious in his work. He also has an amazing way of dealing with customers and is quickly proving to be a major asset to Don’s.

Chris Whelan – Lead Installation Technician/Gas Fitter 2

Chris is our head Installer and is in my opinion one of the greats.  I have seen a lot of head mechanics but none hold up to the amazing talents of Chris Whelan.  He is an artist when it comes to making a furnace or a/c installation look perfect. In a world full of companies that just want to get the job done and don’t pay attention to detail, Chris is an oasis in the desert. He trains all of our beginners the way to do the job with style and excellence and have the equipment run at its optimum performance. Chris is also a gas fitter 2 and licensed refrigeration a/c mechanic. On the odd weekend he will help us with service calls and if he isn’t doing that he is renovating one of his many homes. Plus I must mention he is a par golfer , so if you need a ringer for your foursome he is your man.

Mitch McDonald – Lead Installation Technician/Gas Fitter 2

Talk about the ones who like to learn, Mitch is always going to courses to improve both his installation and service knowledge. Presently he is another one of our Lead installers , however does service calls for us as well. We were lucky enough to get Mitch fresh out of his Gas Fitter 2 schooling and was a pleasure to train. He picked up fast and was probably the fastest to move into a lead hand position. His plans are to be a trainer both in service and install and to move into a more managerial position in the future. Mitch enjoys playing his guitar to his lil buddy jeff  ( his Cat ) and his girlfriend when he is not learning.

Brenden Berger – Lead Sheet Metal Technician/Gas Fitter 2

Brenden came to us while he was still in High School and we have never looked back. He is currently just finishing up his Sheet Metal Apprenticeship and does the majority of our Ductwork jobs from retrofitting existing homes to our large Custom ones. He has learned his craft from Rolf Kellar who is our head Sheet Metal Mechanic .  Brendens workmanship is a thing of beauty ( if sheet metal ductwork is your thing) Brenden is also finishing Gas Fitter 2 License at the top of his class. Brenden also volunteers for programs at the Erin Village Alliance Church

Mike Baird – Installation Technician/Gas Fitter 2

This is Mike’s second time at Don’s. We originally got Mike right out of Gas fitter 2 schooling and he was one of the most sought after students . He finally got tempted to seek greener pastures BUT came back home to us.  Mike is a great person and everyone wants him as there second in command. Mike is working himself into the next lead hand position . His abilities to be our next lead hand are not only because of his amazing attention to detail but also his ability to relate with customers. We refer to Mike as our prodigal son. Welcome home Mike.

Spencer Cowling – Installation Technician /Gas Fitter 2

Spencer is another one we got fresh out of school. Spencer is a gas fitter 2 and will  be our next Sheet Metal Apprentice, he is Brendens helper and has taken well to the sheet metal part of our business. He spends most of his free time as a volunteer with a local youth shelter.  If you are looking for great cause to donate to please look into “ Highlands Youth for Christ” The Door.

Ashley Powell – Installation Technician/Gas Fitter 2

Although this is not Ashley’s first career we believe this will be his full time one. Ashley wanted a career that was more challenging and rewarding so he decided to get his gas fitters licence and find a job. We were fortunate to be the company he choose to do his co-op with and after a very short time with us we decided we weren’t letting him go. Ashley has been with us since September 2018 and is also one of the lead hand helpers. He is now a licenced Gas Fitter 2 and will be starting his a/c apprenticeship shortly as well. He also has an infant  little girl at home and spends as much time with her and his wife as he possibly can.
