At Genuine Comfort, one of the most common questions we get from our customers is, “Do I really have to replace my furnace and air conditioner at the same time?” We’ve been hearing this question more and more frequently as the new year approaches, bringing with it new regulations and the potential for rising HVAC costs.
While some HVAC contractors recommend replacing both units simultaneously, it may not be necessary for every situation. Keep reading to learn more about the future of the HVAC industry and how to determine whether you should replace your furnace and air conditioner at the same time.
Understanding the 2025 HVAC Regulation Changes
Beginning in 2025, the HVAC industry is preparing for a shift toward more environmentally friendly refrigerants. While this is a major step forward in the fight against climate change, these new regulations are expected to increase the cost of air conditioners and furnaces by as much as 17 to 32 percent.
As the current standard refrigerant, Puron, is phased out, the demand for it will increase as people stock up. This will drive prices higher. Homeowners may choose to replace their systems ASAP to avoid cost increases.

Evaluating Your Needs
As you consider whether you should replace your furnace and air conditioner simultaneously, you must first evaluate your current HVAC system to determine whether it’s worth it.
While the lifespan of your HVAC system can vary based on many factors, a general rule of thumb is that furnaces last around 15 to 20 years and air conditioners last for about 10 to 15 years.
Factors that might warrant replacement of your HVAC system include:
- Frequent repairs
- Reduced efficiency
- Poor performance, including inconsistent temperatures
- Higher energy bills
- Poor air quality
- Weak air flow
You should also keep in mind that some systems work best when they’re compatible. However, mixing an old air conditioner with a new furnace (or vice versa) is possible, especially if the older unit is still in good condition.
Financial Considerations
Your budget also plays a significant role in this decision. Buying both units at the same time comes with a significant price tag; however, some companies will offer a discount if you replace the whole system at once. Plus, you’ll likely save money on your energy bills thanks to the new system’s increased efficiency, and there may be rebates or tax incentives available to decrease the cost.
Staggering the replacements, on the other hand, splits the cost. By replacing one element at a time, homeowners can save their money over time to cover the expenses. While there may still be discounts or incentives out there, they may not be as significant.
When to Replace Both Units
If your goal is to maximize energy efficiency, installing a matching system is the way to go. Newer systems benefit from technological advancements and smart features designed to use less energy while still keeping your home comfortable.
Furthermore, when both units are from the same brand and series, they’re likely to be more compatible and perform better. Plus, it could simplify warranty coverage.
Finally, it’s a good idea to overhaul the whole system when replacing one unit isn’t cost-effective due to the need for expensive repairs. At some point, it’s smarter to spend a little more for a replacement than keep shelling out money for maintenance.
When to Replace Only One Unit
That being said, it’s okay to replace just one unit if you can’t afford both at the same time. Any improvement is better than nothing! If your furnace or air conditioner is relatively new or in good condition, it may not need to be replaced, anyway. For example, if your furnace is failing but your air conditioner is in good condition, it probably makes the most sense to only replace the AC.
Tips for Avoiding Pressure from Salespeople
The more money you spend, the more the HVAC company profits, which means that technicians may try to pressure you into products or services that you don’t need. Be careful to ensure you don’t fall for their misleading sales tactics.
The best thing you can do is seek another quote or a second opinion if you feel pressured to replace both units. Don’t rush into a decision — consider your needs, budget, and long-term plans before committing to a big expense.
