Reviews from Old Westbury

What Old Westbury Customers Say

"After being swindled by other companies, Around the Clock was extremely helpful. I contacted them to set up an appointment, and shortly after Greg, the owner, called to say he was personally coming to check my tankless system. Unlike other companies, Greg and team came ready to work on day 1 (perfectly on time) and spent a few hours learning the system and initiating the maintenance it needed. Greg and team came back the next day to finish the job and collect payment. Very good experience with them."

"Around the clock was so helpful during a very stressful time! They came on a Sunday when they said they would, were so helpful and kind. Their price was fair, we were totally blown away by their honesty and professionalism. Would highly recommend in an emergency and we will be using for routine maintenance."

"My air conditioning broke during July heatwave. Called several companies who couldn't get to me til the following week. Then I called Around The Clock. He offered to come the next day at 630am!! He found problem right away and fixed it. Forever grateful to Around The Clock. It was 85 degrees in my house and my dog was suffering from dementia. Such a relief to have air conditioning repaired so quickly."

"The heat at my parents' rental property was on the fritz, and I need the heating issue fixed ASAP. I contacted Around the Clock and was able to get an appointment quickly. Greg and Liam came to our house, fixed the unit, and explained in detail what the issue was and what might arise down the road. 10/10 would recommend!"

"Gregory and his brother both did maintenance on our boiler. They are very diligent and caring people and deeply care about their customers. We thank them for their time and service. That shows the solid reputation of Around the Clock as the company."
