I called on a Monday, had an appointment for Wednesday, got a call back later in the day and was able to secure a same-day appointment for the technician to come out and do an assessment. He was able to come back on Friday to install the outside plug for our electric car charger. The charger we purchased had not yet arrived yet, but when it did arrive a couple days later, the technician was back to install the charger. I would definitely use Haas & Sons again!
