“Tim replaced our water heater and furnace and installed AC and was very reasonably priced. Around the Clock has worked on many homes in my area, so I felt confident in his familiarity with the layout of my home. Tim is knowledgeable, professional, and friendly. I highly recommend Around the Clock especially for the Blackfield homes in the Gemello neighborhood.”

-Terri T.

“I have been using Around The Clock’s services for about 30 years now, and we’ve had nothing but great experiences with them. They have done plumbing and heating repairs on our own home and several rentals that we manage, and they even completely redid our heating and hot water systems several years ago. They do great work!”

-Brandon B.

“We had a great experience with Around the Clock Service. They were on time for the estimate, gave us our options, and we picked the right system for us. They were very neat and clean when installing the system. They recommended a water softening system to go along with the Insta hot and it was the best thing we ever did. On a scale from 1 to 10, they are definitely a 10.”

-Chris A.

“I recently used Around The Clock to open a sewer drain blockage at my house. The arriving technician was courteous, professional, and very knowledgeable about all aspects of plumbing. Within minutes of reviewing the sewer layout of the house he went to work, no BS or standing around to add additional costs to the job. The job was completed in a timely manner, and the cost was very fair. I will definitely use their service again.”

-Tom C.

“Overall is very good, I’m particularly happy with the proprietor. The owner really understands the layouts of the neighborhood houses, and that has been a huge help to me.”

-Debbie S.

“Working with Around the Clock was seamless. Everything was done right and came out great. I would definitely recommend them to anyone in need of their services.”

-Gina D.

“Around the Clock has provided me with plumbing (water purification system) and heating and air conditioning. They are always excellent.”

-Zach P.

“Great staff! Great work. Would recommend them for any work you need done!”

-Wes M.

“Around the Clock Service is really helpful. If they don’t get the job done the first time, they’ll come back with reinforcements!”
