We had for AJ Leblanc to come and install a toilet that was still in the box. When they went to take it out, they found it was broken. They were very nice and told us they would come back when the new one arrived. When we finally received it the same day, they came back right after we called to install it the same day. We would have had to wait over a week if they hadn't come back that same day. Thank you so much to AJ Leblanc for being so accommodating. Would call you again if needed. I see why yu were voted number one plumber.

Called to have an electrician come over to get a quote for some outlet fixes and panel repair. The guy was nice, examined the house, and said he'd get us a quote. A week goes by with no quote. I phone the office and ask what's up with my quote. The office says they'll look into it. Another week goes by and nothing. If you don't want new customers, just say so upfront! Don't waste my time, please.
I will be using another, more responsive electrician and won't entrust my HVAC installation to such a company either. FOLLOWUP: The company was very responsive upon seeing this review. I received emails and calls apologizing and offering a discount, so it does seem that they care about their reputation and new customers. I presume that they are looking into what happened in my case, so maybe future customers will have better service.

We called for service because our ac is not working! A technician came out and found there was a leak that was unrepairable. The unit is probably close to 15 years old. We were quoted thousands of dollars less than another business for replacing the heat pump. The reason we called another business is because we were told that the next service date could be as late as early July.and we are supposed to have a 95 degree day this weekend!
After talking with the technician and the office, they were able to squeeze us in the next day since it was basically a swap out. Thank you so much, AJ Leblanc! I wouldn't be able to stand 95 degrees in this house, with stairs and on crutches!

They are wonderful in most regards except scheduling-twice they missed the mark with me. Once at install at a townhouse complex when they should have known we needed to give 24 hour notice to residents because the main water line had to be shut off (they have done work here before) and the other with the permitting process - I have a life too and they apparently do not consider that which has been the most frustrating part of the process

Our pilot light went out on our water heater and we called AJ Leblanc who had someone there within 2 hours: Robert was knowledgeable, courteous and professional. He fixed the problem right away and showed us what to do so it would not happen again. He also gave us some advice on scheduling maintenance which was very helpful. Overall a great experience and we would highly recommend him.

I had an electrical issue and my experience with AJ LeBlanc was excellent! The administrative staff was friendly and helpful ensuring a timely appointment. I was very impressed with Tucker, the electrician, since he was knowledgeable, thorough, and articulate in explaining everything he was doing. I have two upcoming appointments for plumbing and maintenance and I am confident I will get outstanding service again.
