I just got a new plug-in hybrid vehicle and wanted a 220 outlet installed in the garage so it would charge it faster. There was the option of using 110 with my car which I used when I first got the car but it takes about 10 or 12 hours to get it fully charged. Since the 220 outlet was just installed, I don’t know exactly how long it will take but I’m sure it’s much faster. I’ve had Haller in the past and was always happy with their work. They came today and gave me an estimate and it was over $200 less than another quote I got. I was so happy that he could actually do it the same day! Very happy with the technician and their service and would gladly recommend them to other homeowners.

Phillip did a great job, paying much attention to detail.I could not have asked for a more thorough preventative maintenance visit.
Chris was very thorough, efficient and had a calming personality. I share that because he was totally comfortable with my inquiries and he explained without hesitation! I appreciate his review of my furnace and ducts pertaining to the system with video explanation to reassure me the work was thoroughly done and system was in good health! This was my first experience with my new annual maintenance contract and I'm very happy and look forward to my next service. I'm about prevention so this annual plan seems to be a good fit to my needs! Customer service is also important and Chris is deserving of a shout out!
