The wage ratio is simple arithmetic: this occupation's median divided by the all-occupations median in the same area and unit. It is not a cost-of-living measure. Location quotient describes the concentration of employment, not relative pay. Neither predicts what a particular candidate will accept.
What do these published wages mean for an offer?
Skilled Trades Headhunters reads the May 2025 figures for Industrial Ammonia Refrigeration Technician in National as an offer reference, not a quote for a particular candidate. For Industrial Ammonia Refrigeration Technician in National, the published median for SOC 49-9021, Heating, Air Conditioning, and Refrigeration Mechanics and Installers, is $61,010 per year. The middle half of the Industrial Ammonia Refrigeration Technician in National wage distribution runs from $48,360 to $77,060, a width of $28,700 per year; that spread shows how much published pay varies within the occupation and area, without assigning experience levels.
For the national Industrial Ammonia Refrigeration Technician comparison, New York-Newark-Jersey City, NY-NJ reports $77,990 per year while Dallas-Fort Worth-Arlington, TX reports $59,560 per year; these are the largest-employment metros with published medians for the occupation, rather than neighboring places to a national estimate. The United States Industrial Ammonia Refrigeration Technician figure pools markets with different work scopes and schedules, so use the area table before setting a local offer.
The highest published medians among the selected national industry rows for Heating, Air Conditioning, and Refrigeration Mechanics and Installers, read alongside Industrial Ammonia Refrigeration Technician in National, are Computer Systems Design and Related Services at $115,910 per year (NAICS 541500); Scheduled Air Transportation at $114,080 per year (NAICS 481100); Air Transportation at $113,960 per year (NAICS 481000). Those Industrial Ammonia Refrigeration Technician in National industry comparisons are national cross-sections, not local industry estimates; BLS does not give us a metro-by-industry wage cut here, and overlapping industry groups should not be added together.
The Industrial Ammonia Refrigeration Technician in National median was $59,810 per year in May 2024, compared with $61,010 in May 2025, a published difference of $1,200. That Industrial Ammonia Refrigeration Technician in National comparison is between separate BLS releases, not the raise paid to the same workers or a projection of next year's offer. Read the $59,810 and $61,010 Industrial Ammonia Refrigeration Technician in National estimates with both dates visible, because the employers and workers represented by the survey can change.
Before offering $61,010 per year for Industrial Ammonia Refrigeration Technician in National, separate on-call duties, overtime, travel reimbursement, tool replacement and any truck allowance separately; prevailing wage and union requirements must be checked against the actual assignment. The Industrial Ammonia Refrigeration Technician in National BLS comparison includes ordinary wages and qualifying incentive pay, but leaves overtime, discretionary bonuses, benefits and relocation outside this wage figure. A candidate's take-home pay and the employer's total cost for Industrial Ammonia Refrigeration Technician in National can therefore differ from the median without either number being an error.
The mapping for Industrial Ammonia Refrigeration Technician in National is broader: BLS groups Industrial Ammonia Refrigeration Technician within Heating, Air Conditioning, and Refrigeration Mechanics and Installers; it does not publish this niche title or credential level separately. When calibrating a Industrial Ammonia Refrigeration Technician in National opening, the work checks include RETA CARO/CIRO, IIAR training, PSM/RMP familiarity; ask for evidence of that scope instead of using a percentile as a substitute for qualification. A broader occupation can combine jobs that a Industrial Ammonia Refrigeration Technician in National buyer would screen separately, which is why the badge and SOC remain beside the figures.
