Went very well. The technician was professional, knowledgeable, and thorough. He also explained what he was doing and why he was doing it. There was no direct charge for the service call as it was covered under a cost effective purchased warranty.

Mark IV is great to work with. After our initial experience we bought a service plan from them and they take very good care of our home. For this job it was a no-brainer who to pick. Everything went great and our home was extremely comfortable this winter.

They quickly identified that the leak was caused by a blockage in the drain pipe from the coils. They cleared the blockage, cleaned up the water, and installed a catalyst to prevent rust from blocking the drain pipe again for the next few years. They then checked all the other parts of the air conditioning to make sure it was well tuned and operating efficiently. We'll definitely continue being repeat customers!

They were professional throughout the process. I paid them a service fee plus an hourly fee to do other work I needed for my furnace. This was all separate from the Angie's list deal.
