We went with Dodge after they worked on my parents' house. The job took longer than expected to get started (manufacturing and shipping delays!), but they completed the work in a timely manner, operating around our ever-busy household schedule. We also had a quick problem right after install and they responded to emails over the weekend, and Keith was here right on Monday morning. I'm glad we went with Dodge Heating and Cooling!
We worked with Dodge to have an Electric heat pump system put in which would also operate as our Central AC unit. They were prompt and professional, Keith was clear throughout the process, and Mae from the office was also extremely communicative. They also installed a new wall unit above our garage, linking it to our condensers for the main air handlers. Overall, a great experience and would recommend to anyone in need of HVAC/heating/cooling systems.
The motor in my central air unit broke and Keith ordered the new motor and brought a window unit for us to borrow until the new part arrived. Once it arrived, Justin and AJ installed it and confirmed everything was working. Everyone was really nice and helpful!
We woke up to a cold house and had no idea why the heat wouldn’t turn on. We put a call into Dodge Cooling and Heating in hopes of them being able to diagnose the problem and fix it. Their office employee was extremely friendly and knowledgeable and right away got us on one of their technicians schedule. Within a couple hours we were notified that the technician was on his way. He quickly diagnosed the problem and fixed it on the spot. He was professional and courteous, moving throughout our home respectfully. We could not be any more satisfied and will share our positive experience with as many people as we can! You won’t find a better company out there when you’re in need of assistance.
Great experience with Dodge from sales to installation. We had a central house AC / Heat Pump installed in an old Victorian. This was a very complex install and they did a great job. The whole team were professionals from start to finish. Highly recommend Dodge!
Keith Dodge and his team are fantastic! They do the job right the first time and provided excellent work quality. I had a couple of questions and Keith responded to my text with a phone call within 2 minutes. I will be using them for many years to come as my service provider.
