Milton Frank Plumbing & Cooling recently came to my house to work on my air conditioning unit. They needed to replace the collector box from our upstairs unit, and they did a good job. Their technician cleaned up after himself and did everything alright. I even signed up for their annual service plan. This was my second time using them, and I had a good experience both times. Plus with the service plan, I'll have them out again to maintain my A/C unit, no problem.
