Terrific company that does outstanding work. The technicians and staff are very helpful and friendly. Have been using for over a decade and continue to receive great service.

I am very happy with the service performed by Grove. The staff was friendly and attentive. They came out and diagnosed the problem quickly and sent a quote for the replacement system with a fast turnaround.

– Joel R.

I’ve never dealt with a company so full of employees who are so happy to be working with their customers! Not just professionals, which one assumes (perhaps wrongly), but engaged with us, from making appointments to completing their tasks in the home, I’ve found them polite and respectful.
