What the reviews say
Water heater replacement & service
Yelp reviewers praised a free Sunday relight, advice on a failing unit and a professional, clean installation.
BBB complaints allege a $1,703.42 double charge (Reliant said a refund had been issued), an unfinished tankless job (answered, not resolved), an unconsented $213 membership (unanswered) and a faulty tankless install that ended in a $2,500 refund (resolved). Yelp reviewers questioned quotes of $670 for a drain valve and $3,400–$6,800 for a new heater. A September 2026 Yelp reviewer alleged a cheaper unit was installed than the one contracted; no response was visible.

The reviewer said the technician installed a water heater professionally and cleanly and explained how to extend its life.
Yelp review
Luis N. · September 3, 2026
The reviewer alleged that after signing a contract for a Navien water heater, Reliant installed a less expensive Rheem unit without authorization, then missed appointments and charged the card on file during the dispute. These are the reviewer’s allegations, not verified findings.
Ask before booking: Ask for the written contract and an itemized list of what's included (permit, inspection, condensate and gas work) before work starts, and confirm how you will be charged and whether any membership is included.
