Day & Night Mechanical Solutions Inc. did an excellent job for me! My condo is old and the heating is via a hot water heating radiator in each of the rooms. I had tried unsuccessfully to have people come and look at it for me then the HOA here referred me to Day & Night and they were the only ones willing to come work on it! Finding the parts for them was a challenge since the unit is so old and once we did find parts that would work with our unit the pricing was high but that was not the fault of Day & Night. When we could find parts for it they were larger than the original unit so they had to make the hole in the ceiling where it was located larger by cutting the ceiling. They did refer me to someone who could do the drywall and patching. The woman who helped me when I first called in was very pleasant and informative. She was quick in responding to my calls and very efficient. The gentleman who came out to do the work and his assistant were prompt, polite and professional. They made sure to keep me in the loop of what was happening and took the time to answer any questions I had. They cleaned up so well after themselves I wouldn't have even known they were here. All of the condos here have the same type of hot water radiators so I have already referred them to several of my neighbors. I feel they were efficient, professional, knowledgeable, trustworthy and confident in their work. For all of these reasons, I would tell anyone who needs work done to have no qualms about calling Day & Night Mechanical Solutions Inc.!
