We had R&R install a new complete A/C Heating system with new ducts in 2011. We had a leak after the first summer with the A/C. R&R came out to try and find the leak, usually within a day or two. It was a slow leak so took several months for the pressure to drop, by that time it was winter. We would wait for summer and have them come out again to try and find the leak. Took a couple years because of slow leak, but they finally resolved the problem. Ended up being the manufacture didn't use right valve, had been updated. Nothing R&R had done during the installation.

They come out every year to service the system.

I would highly recommend them to anyone.
