This roundup covers HVAC news published October 28 through November 3, 2026. As always, company names appear only because they made the news. HVAC Zone is a multi-brand dealer, and nothing here favors one manufacturer over another.
1. Equipment prices: residential demand recovers, and more increases are coming
Third-quarter earnings reports sent mixed signals. According to ACHR News, one major manufacturer reported more than 30% growth in its Americas residential business and raised its 2026 U.S. residential market estimate to 7.5 to 8 million units. It also announced an 8% price increase on residential equipment, effective toward the end of the fourth quarter. Executives cited roughly $800 million in input-cost headwinds for the year, about half of it from tariffs. Another manufacturer, reported by ACHR News, saw residential revenue rise just 3%, with segment profit down 18%. It blamed competitive pressure and inflation, and said it plans a broader launch of entry-tier residential equipment in the first quarter of 2027.
What it means for you: if you're planning a replacement, check the expiration date on any written quote. Ask whether the price is locked if the job slips into next year.
2. Heating oil costs jump 21% heading into winter
ACHR News reports that the U.S. Energy Information Administration expects residential heating oil to average $5.26 to $5.97 per gallon this winter, 21% higher than last year. On October 21 the federal government announced it would release up to one-third of the Northeast Home Heating Oil Reserve. AHRI data in the same report show oil furnace shipments up 15.7% in August compared with a year earlier. Contractors interviewed said more oil customers are asking about alternatives but holding off on big decisions. Their advice for now is to get oil equipment serviced early, including the filter, pump screen, and nozzle.
3. Dual fuel gets a new role
Two pieces this week looked at pairing heat pumps with fossil-fuel heat rather than replacing it outright. ACHR News quoted engineers from several manufacturers. In many markets, they said, the heat pump is becoming the primary heat source, and the furnace covers only the coldest hours. They agreed that the switchover point should be set from the home's heating load, the heat pump's low-temperature output, and local fuel prices, not from old rules of thumb. A companion piece in ACHR News applied the same idea to homes with hot-water boilers: the heat pump carries most of the season, and the boiler takes over in extreme cold. Both stressed proper heat-loss calculations and controls.
From the field: HVAC Zone's own guidance on our cold-climate heat pump article matches this trend. Start with a Manual J load calculation, size for your actual design temperature, and set the switchover point from real numbers, not a sales brochure.
4. Hackers target connected refrigeration controls
ACHR News reports a new wave of cyber incidents on November 2 affecting supermarket refrigeration in at least five European countries, including Sweden, Belgium, Ireland, and Estonia. That followed hundreds of compromised stores in France in October. In some cases attackers switched evaporators into defrost or raised freezer setpoints to 50°C (122°F), forcing stores to discard product. France's national cybersecurity agency had already warned about compromised remote refrigeration controllers from more than one manufacturer.
The lesson reaches beyond grocery stores. Any HVAC or refrigeration controller that can be reached from the internet, including building automation systems, remote-monitoring gateways, and some smart thermostats, needs basic protection.
5. Refrigerants and TFA: EPA proposes monitoring
North Carolina Health News looked at trifluoroacetic acid (TFA), an ultrashort-chain "forever chemical" formed when some newer low-GWP refrigerants, such as HFO-1234yf used in most car air conditioners, break down in the air. The EPA's proposed drinking-water rule from July would add TFA to a list of 30 unregulated chemicals that water systems would monitor from 2028 to 2030, without setting a limit. Detections in local tap water don't show where the TFA came from. This is a developing science question to watch as the industry moves to lower-GWP refrigerants.
Quick checklist: what to do this week
| Story | Who it affects | Practical step |
|---|---|---|
| Equipment price increases | Anyone planning a replacement | Check quote expiration dates and price-lock terms |
| Heating oil up 21% | Oil-heated homes, mostly in the Northeast | Schedule a tune-up now and get a dual-fuel or heat pump estimate for comparison |
| Dual fuel's new role | Homes with a working furnace or boiler | Ask for a load calculation and a switchover point based on your fuel prices |
| Controller cyberattacks | Businesses and homes with connected controls | Change default passwords, update firmware, and keep controllers off the open internet |
| TFA monitoring | Everyone, long term | Prevent refrigerant leaks. Leak-tight installs and proper recovery matter. |
Limitations
Manufacturer earnings figures come from company reports as summarized by trade press and describe national trends, not local prices. Heating oil figures are forecasts. The cyber incidents are still under investigation, and no attacker had been publicly identified as of November 3. The TFA rule is a proposal, not a final regulation.
Not an endorsement: manufacturers are named only because they made the news. HVAC Zone Inc is a multi-brand dealer, and the Hub is brand-neutral.
