My home is nearly 100 years old and uses a boiler and radiators for heat and a high velocity SpacePak system in the attic for air conditioning. I bought the home in 2020 and it had been flipped, so you know it has its fair share of quirks. Dave and the crew have serviced all aspects of our heating and cooling systems at this point, from smaller boiler issues to much larger AC issues. The AC system was basically falling apart when I moved in and they helped me get a few extra years out of it. This past spring, we finally pulled the trigger on a complete replacement. Dave came to look everything over again and gave me a few different quotes to choose from. The team dismantled the old system and installed the new one in about a day and a half. Great! But once summer rolled around and I started using the new system, I found that it wasn't cooling like it should. Uh-oh. Dave and the crew put in countless extra hours and additional labor (at no cost to me) until it was all running correctly. It turned out it was no problem with their installation (not that I had any doubts) but with some very specific and hard-to-detect issues with the manufacture of the condenser unit (which was brand new from the manufacturer). I was blown away that Dave and his team would put in so much extra effort to get to the bottom of things and that they maintained their usual friendly, professional attitude even though it was a frustrating situation for them working in a hot attic! All along the way they were very communicative and had ideas and plans and back-up plans and kept at it until they solved the problems. I'm so happy I went with Dearborn Heating and Cooling for this work. I can't imagine another crew would have had the same commitment to quality or the level of knowledge needed to solve such a specific, unexpected issue. They really stand by their work and won't stop until the customer is happy, which feels really rare these days. But then, this is a family business that's been at it for over 80 years, so they know what they're doing! Big thanks to Dave and the whole team. You guys are heating and cooling heroes!

In Summer 2025, I called because my AC system was no longer performing normally. It would run continuously during 80-degree weather and could not keep up during 90-degree weather. I have lived in this home since the system was installed and knew that airflow from the vents was significantly lower than it had been in prior years. Because the high-velocity system and ductwork are located in the attic, I specifically requested that the attic ductwork be inspected. During both the original visit and a follow-up visit, I was told the airflow was acceptable, but the attic ductwork was not inspected. Instead, I was advised that poor insulation was likely the reason the system was struggling. After adding insulation, the problem became much worse. When I started the system the following spring, some vents had little or no airflow at all. A different Day & Night technician visited in Spring 2026 and found loose duct connections, which he fixed, and that significantly improved airflow in part of the house. However, the other half of the house still had very poor airflow. I was told that follow-up service could be performed later that week if additional issues remained. The issues did remain, but no call was received and no follow-up service was performed. I contacted the office multiple times over the next two weeks. Each time I was led to believe that service would be scheduled, but it never occurred despite several cool days that were suitable for attic work. After waiting approximately two weeks, I contacted another HVAC company. They inspected the attic ductwork on their first visit and found a compressed duct and a disconnected duct. The repairs were completed during that same visit, at approximately half the cost of Day & Night's most recent service charge. Airflow in the affected area of the home is now dramatically improved and significantly better than it was when I first reported the problem in 2025. Mechanical issues happen, and even experienced technicians can miss a diagnosis. My disappointment is that repeated requests to inspect the attic ductwork were not acted upon, follow-up service that was discussed never occurred, and I ultimately had to hire another company to identify and resolve the remaining problem. Based on this experience, I can no longer recommend Day & Night.
