Excellent customer service and repairs were addressed in timely manner without any issues. 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. Have also recommended Hargrave to family members, and the experience has been very positive. Special mention goes to Steven M. for always providing outstanding troubleshooting, resolution and maintenance. Most recently, I received a visit from Mike C. for the annual maintenance program and he also provided outstanding service. I would absolutely recommend Hargrave, based on my experience to date.Posted on EJ ZTrustindex verifies that the original source of the review is Google. Technician arrived early for maintenance appointment. My HVAC system was checked, cleaned, and optimized for peak performance. Thanks again for your excellent service.
