"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!"
