We just bought a home, and scheduled Residential to come out to clean and inspect our heater.

Jim arrived right on time, and was very informative, explaining to me about the basic details of our heating system. Then he was diligent in cleaning and inspecting the unit (and that thing was really dirty!). Finally he walked me through his findings, going over the condition of the unit, explaining our next steps and maintenance, and making some suggestions on how we can have a more efficient heating system.

Jim was extremely friendly and courteous. I can't think of a better experience and we will look at using them when it's time to replace and relocate our heater in the future. I strongly recommend this company (especially Jim S.). :)
