What customers said about cleaning
T.E. Spall & SonDave explained everything very clearly and made sure our heater was running properly. Very knowledgeable and friendly.
C & C Heating & Air ConditioningGreg & 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.
Bama Air Systems Mechanical Contr…Brandon Busby usually does our work. He’s on time and always very courteous and professional. He does a thorough job and make sure everything is working properly before he leaves and never seems to grow tired of me watching him. Do what he does. His patience is quite remarkable. I would highly recommend him and Bama Heating And Air.
USA Pro-VacGood service for cleaning all duct and chimney. Took 1.25 hours overall. Technicians are clam, informative, professional.

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.
