The HVAC industry's pricing pressure did not end with August.

Another round of manufacturer and supplier increases is taking effect throughout September, with adjustments reaching as high as 15% depending on the product category. 

For contractors, the new increases hit exactly the kind of everyday materials that can quietly eat into job margins.

Five Suppliers Are Raising Prices

ACHR News and Geary Pacific's manufacturer tracker list the following September changes:

  • Bard service parts: price increase effective September 1; percentage not disclosed.
  • OmegaFlex TracPipe: 6% increase across TracPipe System products effective September 1.
  • Jones Stephens: 5% to 15%, depending on product group, effective September 3.
  • M&M Manufacturing: up to 6%, effective September 21.
  • Snappy: up to 6%, effective September 21. 

These are not limited to premium systems or unusual specialty equipment.

They touch service parts, gas piping, fittings and sheet-metal products used across routine residential and commercial work.

A 15% Increase Can Wipe Out Margin Fast

Contractors frequently quote projects before every material is actually ordered.

That becomes dangerous when supplier pricing changes between estimate and purchase.

Imagine a contractor prices a job in late August using existing fitting and material costs.

The customer waits a week to approve it.

By the time the order is placed, some product groups may be 15% more expensive.

If the quote is fixed, that increase comes directly out of contractor margin.

Price Books Need to Move Faster

The practical response is not complicated, but it does require discipline.

Contractors should be reviewing:

  • Price books
  • Outstanding estimates
  • Supplier quotes
  • Material allowances
  • Quote-expiration periods
  • Job-cost assumptions

Longer commercial projects may also need escalation language where material costs can move significantly before installation.

September Follows an Already Expensive August

The latest increases are arriving immediately after another broad wave of supplier adjustments.

Geary Pacific's tracker shows August increases from manufacturers including Daikin, Goodman, Amana, Bard, Eaton B-Line and others, while Lau parts rose 16.2% to 16.8% on August 31. 

That makes September look less like a standalone price event and more like a continuation of a wider pattern.

Contractor Pricing Cannot Lag Supplier Pricing

One of the easiest ways for an HVAC company to look busy while making less money is to sell work using outdated material costs.

A five-point margin can disappear quickly when several ordinary components rise at once.

And because many of these products are hidden inside an installation, the homeowner may never realize why the contractor's cost changed.

With supplier increases now reaching 15%, contractors need to treat pricing updates as an operational process — not something they revisit once every few months.
