I've been using Needham oil for 3 years, originally switched to them for oil delivery. Since switching they have done 2 heating and central air installations for me in 2 properties. Randy is very professional and gave us great advice on the equipment to install. The installers are great, professional, courteous and very good at what they do. If you are looking for a new oil dilivery provider, a HVAC installer or someone to service your HVAC the look no further. You will 100% satisfied with Needham oil.
