Verified record
RK Heating, Plumbing, Cooling LLC works on furnaces, water heaters and heating systems, and its website lists a service area that runs from Rangeley, Phillips and Strong down through Farmington, Wilton and Jay to Auburn and Lewiston. The company says it has grown from a single truck and has kept homes and light commercial buildings across Maine warm and cool for 38 years. The Maine state registry lists HVAC licence MS10008320 as active, with Richard A. Karkos as the holder of record. A recent customer said Rick educated them about their system and taught them how to keep it in top condition. A recent reviewer wrote that he explains and answers questions thoroughly, arrives on time and leaves the workspace as he found it, and that when quoting he shares how he would do the job in his own home. A 2026 customer who had bought a new home with an old furnace said Rick gave an estimate and explained the options, and they chose a hybrid hot water heater with a new furnace. That 2026 customer wrote that it was the second system he had put in for them. A 2026 reviewer said Rick has taken care of their heating system for 20+ years, installed it and keeps it in good repair. A 2025 customer said the company replaced an old electric tank with a new heat pump hot water heater at a reasonable price. A 2025 customer said Rick fixed the furnace in their trailer.
Rick was incredibly professional, knowledgeable, and friendly. He educated me about my system and taught me how to keep it in top condition. If you need any work done on your system, you’d be crazy not to call him!
He responded very quickly and resolved the problem. Thank you so much!
