"We awoke to a completely blocked/backed-up Kitchen Sink, with the water backing up on both sides of the sink. I called Hosack Plumbing Cooling & Heating (NOTE: It is the SAME BUSINESS as SC Hosack Plumbing & Excavating listed on Angie's), and they scheduled me for an afternoon appointment the same day. Steve actually arrived at the START of the 4-hour service window, which was REALLY nice so I didn't have to wait half the day. Steve quickly determined where the blockage was in the drain pipe, and he got it removed. It was the first-time in 35-years we had this problem with our kitchen sink, and Steve explained how over time the blockage accumulated until it finally closed off all drain flow. Steve then gave us some good maintenance information for us to do once a month to help future blockages from forming. It's well-worth the cost of a bottle of Dawn Dish Soap once a month to help make sure it doesn't happen, again, and avoid the cost for this type of service in the future. :) "

"Did a good job - efficient - and reasonably priced"

"Called Sam on Friday for quote for water heater replacement. Said he could do Monday afternoon or Tuesday morning. Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

"Both the estimator Kevin the two installers who visited my home were very professional and kind. They answered all my questions and provided a very reasonable price for the installation of the attic insulation. I feel I was very informed on the federal rebate that was available for this installation, as well as on the recommendations of quantity of insulation I needed per residential standards and codes. I would recommend Anton and will use them in the future for my HVAC needs!"

"On time, thorough, and efficient."

"Lucas was prompt and professional. He diagnosed the issue and replaced my capacitor in less than 30 minutes! He also checked the freon as well. I highly recommend Lucas with ComfortWorks Heating and Cooling."
