I have been using the services of Day & Night Mechanical Solutions for about twenty years now and they are very good. They are always on time, prompt and if they are late or anything, they let you know. They come out quickly if you have an issue, which is fairly wonderful. They are upfront and relatively honest. They tell you what's what and I never feel like they are pumping up the expenses by recommending work or parts that aren't really needed or aren't up to the mark. I began using them when they installed my furnace and air conditioning in a different house. Then their name changed and I didn't realize it was the same people under a different name and logo, but when I did I called them back. Most recently they came out to do a maintenance and cleaning job on my air conditioning and furnace. They did a great job as always. Overall, I'm happy with the service they provide.
