Steve's Plumbing Heating & Air Co…Franko was here fast and he was very polite and efficient and very knowledgeable
Lasting Legacy Plumbing Heating a…Daniel and isaias were incredible. They even brought portable AC units for my wife and I to use in the house while they worked. Everything was perfect and cleaned up at the end and they were also incredibly kind and service oriented. I installed the thermostats myself and one didn’t work, Isaias helped me figure it…

We’ve had several situations where a heating unit failed right when temperatures dropped, and they’ve always come through. Today was another one of those days, and the response time…

My heater stopped working and they were able to come out the same day, which was a huge relief. Art was the technician and he was extremely professional, knowledgeable, and took the time to explain everything clearly. He diagnosed the issue…
Steve's Plumbing Heating & Air Co…Steve~Your company installed our FAU/CAC new & we have referred several of our neighbors to you.

Lasting Legacy Plumbing Heating a…Awesome performance from Juan who took care of my water heater in Redlands. Service was quick and informative. I use the coupon for great deals and great service.

How we grade
Satisfaction (54%) — Recency-weighted star average (2-year half-life), shrunk toward the category mean by review volume; the company’s own lifetime average as the prior; absolute: 4.0★ = 0, 5★ = 100.
Reliability (24%) — How rarely jobs go badly: share of 1–2★ reviews — 60% the last 24 months (or the 20 newest if fewer), 40% all-time; 0% = 100, 15%+ = 0; the category percentile can only raise it.
Craft & service (penalty, up to −10) — Google review highlights: Quality, Professionalism, Responsiveness, Punctuality — how rarely reviewers flag them as a negative, per review since highlights began; 0% = 100, 5%+ = 0. Subtracted from the score (up to −10), never averaged in — clean highlights are the norm, not a bonus.
Value (14%) — Customers’ own price verdicts (Great / Reasonable vs Overpriced) and Value highlights; 65% absolute (all “reasonable” ≈ 80, “great” = 100), the category percentile can only raise it.
Momentum (penalty, up to −10) — Penalises only a real slide: last-12-month average below lifetime (−0.5★ = 0). Still 4.8★+ over the last year, or steady/improving = 100. Subtracted from the score (up to −10), never averaged in.
Replies to reviews (7%) — How often the owner publicly replies to reviews under 5★ (1–4★). Needs 3+ such reviews, otherwise not counted; 65% absolute (80%+ replied = 100), the category percentile can only raise it.
