Your EMR Is Pricing You Out of Bids: What a Mod Above 1.0 Costs an HVAC Company

An EMR above 1.0 does two things to an HVAC contractor at once. Your experience modification rate is the multiplier carriers apply to workers comp premium. Above 1.0, it loads every workers compensation premium by the amount over the line. It also fails the bid screens that general contractors (GCs) and public owners run before they ever read your price. A 1.25 mod means a 25 percent surcharge and, on plenty of commercial jobs, an automatic rejection.

This is a renewal problem for established HVAC companies, not a startup one. Your mod moves every year on payroll and claims from three years back. By the time the new number lands, your bid eligibility for the next twelve months is already set. This guide covers what a mod above 1.0 costs in dollars and in lost work, and how to walk it back down.

What an EMR above 1.0 costs you

An EMR above 1.0 costs an HVAC contractor on two lines at once: a bigger workers comp bill and a shorter bid list. The mod is a straight multiplier, so a 1.25 rating adds 25 percent to premium. On a $150,000 base premium, that 1.25 mod bills out at $187,500, about $37,500 over the industry-average price.

Run the same math the other way and a 0.85 mod cuts that $150,000 to about $127,500. The swing between a 0.85 and a 1.25 mod on one mid-size HVAC payroll is roughly $60,000 a year, before you count a single lost bid. (That is the number most owners never see itemized.)

The table below pairs each mod band with its premium effect and its usual bid outcome.

The bid lists an EMR above 1.0 locks you out of

An EMR above 1.0 gets an HVAC contractor's bid rejected because prequalification screens read the mod before price or scope. Most general contractors set the cutoff at 1.0, and a mod over 1.25 is disqualifying on many project types. Refinery, chemical, and infrastructure owners commonly go lower, wanting 0.85 or better for prequalification.

Those EMR bid requirements are usually automated: platforms like ISNetworld and Avetta flag any mod over the client's threshold, and the bid never reaches a human. Public agencies write the same rule into their prequal packets, and Virginia's DOT lists EMR as a standard factor tied to a contractor's claim history.

The three-year window behind your mod

Your experience modification rate for an HVAC company compares three years of actual workers comp losses against the losses expected for a shop your size and class. Then it drops the most recent policy year. A mod effective in 2026 runs on 2022, 2023, and 2024 claims, following the National Council on Compensation Insurance (NCCI) experience-rating formula. Claim frequency moves it more than any single large claim.

The mod lags your actual safety record by design. A safety overhaul you rolled out this spring won't move the number for up to three years. A claim you closed last month keeps counting until it drops out of the window. Open claims hurt the most, because the mod uses the reserve, the carrier's estimate of the claim's final cost, not what you have paid so far.

An inflated reserve on a claim that is basically settled quietly props your mod up. (Carriers rarely lower a reserve unless someone asks.) Reviewing open-claim reserves before the mod calculation is one of the few levers that works inside a single year.

What is a good EMR for contractors?

A good EMR for contractors is anything below 1.0, since 1.0 is the industry-average baseline. Below 1.0 earns a workers comp credit and clears most bid screens. HVAC companies chasing hospital, refinery, or public work should aim lower, around 0.90, to stay on the strictest lists.

Here is how the bands tend to play out for an established HVAC contractor:

• Under 0.90: A premium credit and a spot on nearly every bid list, including high-hazard work.
• 0.90 to 1.0: Better than average, safe for most commercial prequalification.
• 1.0 to 1.25: A surcharge and a flag on stricter specs.
• Over 1.25: A steep surcharge and disqualification from many bids outright.

Workers comp itself is getting cheaper for contractors right now. NCCI's 2026 State of the Line reports approved filings reducing written premiums an average of 5.0 percent from 2025 to 2026. A high mod stands out even more when base rates are falling. A flat-fee broker like Coverwatch pulls the mod worksheet about 90 days before renewal. It audits open-claim reserves and payroll class codes for errors, then files corrections with the rating bureau before the new mod locks in.

Getting your mod back below 1.0

Getting an HVAC company's mod back below 1.0 starts with the worksheet, not the safety binder. Audit it for payroll misclassification and inflated open-claim reserves, close stale claims, and file corrections with the rating bureau before the calculation locks. Then let three clean years roll through the window. Left uncorrected, a high mod can even trigger an HVAC insurance non-renewal.

One mechanical contractor we worked with saw its mod jump to 1.18 off a single shoulder injury, and the claim had paid about $85,000. A year after the tech returned to full duty, the carrier still held a $140,000 reserve on it. Getting that reserve reviewed down to the real number recalculated the mod to 1.02, enough to clear the 1.05 cap on a municipal job the company had already written off.

The rest is the slow lever: fewer claims, faster return-to-work, and accurate payroll classes so your expected losses aren't understated. The full coverage stack sits in our HVAC contractor insurance guide, and the renewal sequence around it in the HVAC company insurance program guide.

Coverwatch runs the mod-recovery math and shops the account across 60+ carriers as part of its flat-fee contractor insurance practice, so a correctable mod doesn't quietly cost you another bid season.
