Thank you again .Posted on Suzanne GonsalvesTrustindex verifies that the original source of the review is Google. Hargrave installed a new furnace and air conditioner in April 2024. Over the past few weeks, the furnace would shut off. I called the office and they connected me to a technician. After giving some information a service call was scheduled. Ian arrived and diagnosed the problem (a simple air flow issue), fixed it and before leaving stated if I had any further issues to call the office and he, or one of his colleagues would return. No charge. Can’t ask for any better. Glad I went with them.Posted on M ChoongTrustindex verifies that the original source of the review is Google. I have been a client of Hargrave for many years. Whether the task is routine annual maintenance for both Furnace or AC unit, or purchase and installation of said equipment, I have been and continue to be very satisfied with the front office and field personnel.
