Kyle is very knowledgeable, personable and courteous. He explained what I need to do when the seasons change and was thorough in the maintenance process, was not rushing through it. I presume the cost was more than reasonable, and I was pleased. I have no knowledge of the going rates.

Greg & Jake worked as a team and replaced the hot water heater in a couple of hours. I watched them check to make sure the water and gas lines were vertical. They made sure the area was clean when they left. They instructed us in the operation of the unit before they left and made sure the water line was clear of air.

I can’t say enough about this company. The techs were very knowledgeable, pleasant and did an outstanding job. Would highly recommend this company. Their price was fair, they didn’t try to take advantage of us or charge an outrageous amount and the work was top notch!

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.
