Here is what some of our customers had to say about our work:

"Excellent job, as usual."

Al, Ayr

"Hello, I had my furnace serviced today and am just doing a follow up email on the service.  Peter was the technician in today and I am writing to pass on good news.  He was fantastic, friendly and made me feel comfortable in what he was doing, being a new home owner and all.  I feel people don't hear positive feedback enough in today's world so just passing on a job well done and many thanks!"

K, Stratford

Just a quick note to say, ' thank you' for a job well done!
Not only did you install a new furnace for me, you took care of the dogs breakfast which was my water heater installed a few days earlier by another company.
It's nice to find a company who actually gets the job done when they say they are going to get the job done.  Your crew arrived when they said they would and they finished up when they said they would.  Plus, they made sure they cleaned up the place before they left....
...Jason and Richard did a great job.  Their attention to detail was dead on and they looked after my home just as if it were their own.  And thank you to Ken for making the plumbing on my hot water tank a thing of beauty.  Peter, my A/C looks great and I'm sure come summer my family will think of you fondly for getting us hooked up.
I have been telling the neighbours about the great job your crew did, which is something I would not do if your company had not delivered in spades.  My electrician was in and said it was so nice to see a job done right and that it was clear you take pride in your work. 
Thanks again for the great job.  It's nice to know there is still a company out there who understands customer service, and who has well-mannered, professional employees who reflect that.

"I had a great experience with Corestar.  They were competitively priced among other providers in the area - and their customer service representative was very informative.  It made choosing Corestar for the installation of my a/c unit that much easier!"

B, Ayr

&Approximately five years ago we first used Corestar to do a site visit, then a plumbing job to add a basement bathroom. Approximately two years ago, we used Corestar to resolve an issue with the hot water tank. Recently we had a problem with the gas furnace not starting. On each and every occasion, from the initial phone call, the resolution of the job and the follow-up phone call, the service was well beyond professional and efficient. Unfortunately, everyone hears about bad experiences and rarely passes on the good ones. As we are not at the property, we need to have the confidence in a reliable and competent service company and their employees, Corestar has provided a level that well exceeds our expectations. It is our opinion that each and every employee that we have been exposed to, represent your company in a way that other service organizations should/could learn from&

Barry, Waterloo

&I placed a call 11 pm Monday evening  and Corestar had a new faucet working happily for us before noon on Tuesday. I would call that response time amazing and we could not have asked for better. More than that, the serviceman from Corestar was excellent, on-time, and gave us a great job&

Matt, Guelph

Id like to pass on our compliments to you and your crew for the good job you did installing our furnace. Despite the chaos, you left our home as clean as you found it (which thrilled by wife), and managed to run to the vents the best way possible, which I appreciate. Your folks were polite and courteous too. All in all a very good job!

Paul, Cambridge

Last week your crew replaced a 30 yr old Lennox furnace with a new Lennox high efficiency furnace and air conditioner package in our home. This was a major purchase on our part and selecting a dependable brand coupled with a reliable contractor was our objective. We are certainly glad we chose Corestar. I wish to commend you and your staff on the excellent, professional manner in which this sale and installation was performed. Such performance is somewhat rare in todays marketplace&We will have no hesitation in recommending Corestar Mechanical to others. Thanks again for making this purchase a satisfying and rewarding experience.

William, Kitchener

Just a short note to let you know how much I am enjoying my new furnace&The service was excellent and the installers were very patient with me and the questions I asked.
