"Michael was knowledgeable, thorough, helpful, punctual and efficient."

"Danny was very good"

"Was very pleased with the service I received from Wahab, Blake and Anna. They were very courteous and respectful and completed the task on time. We have dealt with trades before and felt that A1 really exemplified great customer service by being friendly and patient. As a customer I pay particular attention to my interactions with team members and look to see whether they are attentive, understanding and responsive to my needs. Customers aren't usually familiar with the technical aspects of heating/HVAC, so we need to understand what the issue is and why the proposed solution is the right course of action. Often times this will require a replacement of units which can entail a significant expense for some, so it is important that Customers are making an informed decision and not being subject to sales pressure due to a lack of understanding or possible health risks. Walking them through the options, without pressure goes a long way towards a great customer experience in this industry."

"Fixed the issue right away and explained what caused the problem"

"Technician wonderful!!!!"

"Explained what he was doing, phoned for assistance on issues he was trying to solve, was friendly and knowledgeable."

"very polite, went right to the job to complete"

"He knew what he was doing"

"- parts are on order, but no has followed up to advise on how long it will take to get these parts yet... That would have been a better client experience. Not the tech problem but A! Chesney should have done this for the client experience."

"Quick, prompt, and respectable service."

"Quotes did not go into any detail, given a price, but I have no idea what I would actually be paying for, what make and model are the units? How many BTU's? What is the SEER? How many DBs? Its very difficult to even consider choosing this company when you dont get any specifics to compare to your competition, especially given that your price point was significantly higher than others. If you are charging more I should be able to see why I should consider paying more. If it is better quality equipment maybe it would be a consideration."

"The work was very neat and the crew left things in great shape. They were able to remove the old furnace with very little damage to the floor, something I didn't think they would be able to do."

"on time, accurate quote, completed job in a timely manner."

"Not sure the reason for the appointment was fulfilled. The technician came to replace a temporary plug which was not the correct one. He said the temporary replacement incorrect plug hadn't leaked, so he didn't replace the incorrect plug with the correct one he brought with him. This is a concern, thinking about this after he left."

"The furnace installers (Abdu/Joe) did a fantastic job! We were more than pleased! Work was completed in good time and clean-up was great. Thank-you"

"The Technician was amazing! What I did not appreciate was having a sales consultant come to my home. I called A1 Chesney because something was wrong with my furnace. I didn't ask for a quote on a new furnace or for parts that do not replacing right now. Nothing ended up being wrong with my furnace but so much time was spent discussing how bad the brand of furnace we have is. A sales consultant trying to convince me that parts that made noise needed replacing and that my 10 year old furnace should be replaced with a $5500 furnace. Had I known that I was going to have a sales consultant come to my home I would not have called A1 Chesney. It was more of a sales call then someone coming to look at my furnace which is why I called. I really liked Jamil, the technician that came. He was great!! But because of the sales consultant tactic used by A1 Chesney, I won't be calling again."

"The technician was fast, honest, and communicated very well."

"Very good service man."

"Nothing to do with the technician (everything was fine with repair/install). The lower mark comes from the time it took to receive the part and to get it installed (almost 4 weeks!). Also, we inquired (2 weeks in) as to the status and no info could be given. As well, there was no heads up call given on installation day. We also had requested a quote for a new fresh/cold air intake system for our furnace and never heard from anyone from your company (until our tech arrived and he gave us the quote). Overall, the customer service was quite lacking. I cant help but think that, because this was warranty work on a failed part, that priority was not given. In todays world ... even with COVID, I find it hard to believe that it takes a month to acquire and deliver a part (no matter how old it is)."

"Very prompt service."

"Chesney service was prompt in -30C weather. The problem was quickly identified and a temporary solution was provided."

"Because of an inexperienced scheduler (who took a long time to find my information ) the technician didnt come out with a needed ladder on the first day. So he dealt with one issue but then I had to call back and schedule a second appointment thereby having to wait an additional 2 days for the most urgent of the issues."

"timely and quality service"

"From the woman who took my call to the technician, I could not have asked for better service. Both were friendly, able to help me in my time of need; technician told me exactly what was happening."

"Rahim was courteous and professional. Respected our home by changing into slippers and maintained social distancing. Rahim left our humidifier and furnace area cleaner then when he came and we would strongly recommend Rahim and Chesneys for all plumbing needs"

To my surprise, someone answered and gave me the support and caring to ease my worry and stress. How can you not be loyal to a company like that? Someone was sent to our house at 9am the next day. I am very grateful to have found A1 Chesney. you have always been so good to us."

"George knows what he is doing in sharpe contrast to the original furnace installer (Kyle) who royally messed up the installation."

I think that amount is outrageously expensive for what is supposed to be only the labor charge to replace the part."

"Had to wait until Monday as answering service not aware that there was availability on weekend with technician familiar with combi boiler system. Danny was great, however, the next day after technician bled the lines the sewer backed up costing me $450 to snake the line to fix, wondered if this was related?"

"the technician really knew his stuff and installed the new tap in short order."

"Had a diff technician each time, I dont like that much. The tech that was here brought up my hot water heater. He mentioned it was 23 years old and beyond its life expectancy. Even tho thats true, its never at all given me any grief, works perfectly delivering hot water to every faucet. Now, however, Im worried about it going kaput in me, and Seniors Daily Living Assistance no longer provides funds to buy a new one. Now they give me a loan to purchase a Hot Water Heater which I have to make payments. Im retired, live on OAS, GIS, CPP and Alberta Senior Support at $195.00/mo. Thats really all I can complain over but he is in his right to inform me of such. Just now Im a worried about it and waiting for it to quit on me. He was very professional, not a conversational type person like the others were. Thanks."

"Not only did Phil fully inform me about the replacement water heater, he pointed out several other potential issues regarding my furnace and piping for the heater. He also gave me a lot of information about the Advantage plan, which I now have. I hope it works the way I understand it!"

"Problems were solved in a reasonable time."

"Service technician was great but I wish theyd been able to find the leak. Our plumber did show us a picture of some water leaking on the bottom. Thank you for not charging us for coming out though!"

"The service from the annual inspection, through the assessment for the new furnace, and its installation went smoothly, and efficiently, and was explained well. The workers were respectful of the Virus protocol, and Inwas very satisfied."

"The technician was rude. Just because he couldn't find a record of A1 doing the last service, he had to be rude about it. A1 is the only company that's been here since the last service. He said my 16 year old furnace should be replaced because all the parts have been now. If it has all new parts, it should work fine. The he complained about something on the cover, but the previous technician never mentioned it. I don't think he likes his job."
