We were looking for a new central air system for our home, and after an intensive search, McMaster was one of the company we contacted, Initially I liked their company mission statement and also their previous customers reviews. So I contacted them. Ron (owner) came out to our home, told him we were interested in a high energy efficient system. Ron was a wealth of information and answered all of our questions. After hearing our wishes, he emailed us 3 options to choose from (good, better, best). We went w/ the 'best' option. Now it was more than what we budgeted for, McMaster offered a no-interest finance for 6mo w/c was great. So we paid cash and financed the rest. Prior to installation, Ron and James kept us updated and were also available to answer many more questions. Anthony came out and did the calculations/measurements and also provided more information. The installation was suppose to take 2 days since we decided to replace all the ducts. The crew came out on day 1 and they kept coming...it seemed like the whole McMaster staff (except the secretary) were at our home, so they were able to get the job done in 1 day, w/c was impressive! Their attention to details was not lacking. The whole crew were professional. Everyone knew what to do, they were organized, they performed their tasks w/ care, kept the house clean and in order. Anthony was great! He came to the house a couple of times after the installation to make sure that our system was running efficiently, he was here when the City inspector came out and he also took care of our Edison Rebate (w/c was being offered at the time we had our system installed). This review is way pass due, and we can't say enough good things about Ron and his entire McMaster crew! Keep up the excellent work everyone! Thank you for a wonderful service.
