  • The owner was not clear on the fees. He did provide with the hourly cost but did not explain that there was travelling fee starting from the moment i call until the technician arrival. For a half an hour service it costed my client over $400 + tax

  • Service of this company is very bad. They did not do any service in my furnace and they charge me the service charge. They did not contact me by phone nor send me any messages via text and email and let me know when they will come to fix my furnace and that lead to the phone call to cancel the service within the time frame of 30 minutes to the company phone number and nobody pickup the phone, only voice mail replied back. Suddenly they send the technician to come to my house without notify me and telling me he come to fix my furnace while I already cancelled the service. Now they charge me the service they did not do on my furnace. I don't understand how they charge the customer like that. Then they send me the invoice through email for the charge that they did not perform on my furnace. They said they call me but their calls have no caller ID and they don't leave any voice messages. So how do I know their call?. I don't think they really regret what they did to me. I don't recommend this company for any services.

  • My furnace failed on December 23, 2025. Nader was out on December 24 and worked until 5:00 pm to install my new furnace. Great service!

    ken K.

  • Honestly the best service ever! I have been so lucky with how they handled the emergency I had. Came the same day and early, and replaced the piece in less than 5 minutes. Strongly recommend this company! Not only that they provided an amazing service but they were very friendly and kept me up to date on what needed to be done and when. I dealt mostly with Nadeer and as I said, strongly recommend him and his company.

  • Nader found a technician who was able to fix the AC hot valve in a condo rental unit . The services were professional and timely. Great quality, service and work ethics. The guy went the extra mile delivering the keys at our workplace after finished the service. They also installed a full AC unit in a big house for us and we have been very pleased with coordination of services, timely service and quality. Strongly recommend these company. Locally owned and operated. Exceptional people to make business with.

  • Our air conditioner stopped working on one of the hottest days of the year. I called All One at 7 pm at night. Nader answered and said he could come right over. He was there in 20 minutes. Got the air conditioner going with a temporary fix so we could cool the house down enough to sleep. Was back with the correct part for a permanent fix at 8:15 the next morning. Nader went above and beyond to help us. Amazing service and expertise. Highly recommend All One!
