I had a new air conditioning unit installed. I had to obtain the electrical installer myself as Brian lacked the skills/certification necessary, and he also did not have a standing relationship with any electricians.
I have since discovered that the capacity of the air conditioning unit that he designated to be installed was oversized by 35-60% (confirmed by 4 subsequent heat/cooling load calculations be contactors for a furnace replacement). This means that I now require a higher amount of airflow capacity for my furnace to properly circulate the air (a wind tunnel when the A/C unit is actively cooling). The supervisor for the company that installed my replacement furnace indicated that he has never seen a residential air conditioning unit installed as large as mine in Calgary.
During the installation, Brian removed my existing electronic thermostat. When I requested it to be returned, he admitted that it had been thrown out and that he would provide a replacement. He avoided contact for a long while and did not return the item during the period he had indicated. When I finally sent a stern email to him indicating my frustration and displeasure he arrived at my home the following day, at which time he said that my treatment of him was "unfair" and that he had "things going on in his life" that prevented him from following through. I advised him that I had made several requests and was not aware of any issues on his end because he had not provided me with any communication. Regardless, the obligation was on him due to his error, and this should not have been a large issue. He should still have the ability to manage his on-going business.
I was very bothered by his verbal attack on me at my home and would not recommend his services to any one based on his VERY UNPROFESSIONAL MANNER and his apparent lack of technical skills for the proper sizing of the unit that was installed.
