Recently ended a very long association with a large home service provider whose focus shifted from ensuring my furnace was clean and had the best chance of a long life to a 15-minute costly visit to just check safety levels. My new heating service provider is Carleton RH&A. They got me out of a jam last Fall, cleaned my air ducts this Summer and most recently did a thorough furnace cleaning and inspection. All contacts have been very professional. I am a satisfied customer. Kudos to Trish for ensuring I have the best heating plan to meet my needs and to Matt who carried out the cleaning and safety inspection.
