    Had an AC system replaced. Price seemed reasonable. Techs Josh and Jeff arrived on time, were friendly and professional and went right to work. Starting outside and then working in a tight attic, they did not stop until system was completely installed. Job was thorough and well done. Weather has been cool so haven't had to use the AC but it sure looks nice. Very satisfied.

    I needed new water valves installed in order to get a new washing machine installed. Donnellys was so helpful from the initial phone call to the instalation. James came to my house within a half an hour of my phone call and the job was expertly completed in less than half an our! I love Donnellys and will always use and recommend them!!

    Thank you Mike and Robert and your tireless crews for replacing my sewer line. You worked hard all day (even in the rain) and never forgot to be courteous and professional and answer questions for this frazzled homeowner - bless you all!
