It’s not unusual to see HVAC prices climb in the summertime. With scorching temperatures and systems working overtime, breakdowns increase and so does demand for replacements. Typically, if you received a quote for a new HVAC system in the winter and waited until mid-summer to act on it, you’d see a price increase of around 5–10%. That’s simply the effect of seasonal demand and limited supply.
But 2025 isn’t your typical year. This summer, HVAC system costs could jump by as much as 30% to 40%. The reason? A sweeping change in the refrigerants used in new heating and cooling systems is reshaping the entire industry—and creating inventory challenges that affect homeowners across the country.
