From start to finish Oxford Energy and all of their employees were helpful, informative and professional. I would highly recommend them for any of their services. We had them perform and energy audit for our house and make a recommendation based on the findings. They had a very competitive quote for replacing the 17 yr old, water heater and AC and Furnace along with additional insulation and sealing in our attic. We qualified for the Sate of NJ energy rebate and Oxford facilitated us through the entire process. Definitely a great company.
