What the reviews say
Water heater replacement & service
Reviewers praised same-day replacement of a leaking heater and a technician who offered several options.
One reviewer alleged a burner plate was loosened during an AC maintenance visit and a quote followed; Abacus replied asking her to call. A tankless repair that failed within hours was fully refunded ($695.36, resolved), and a missed-appointment complaint was answered with a rescheduled visit and a free month of membership.
