Image for Five Signs It’s Time to Upgrade Your HVAC System in 2025

As we ring in the new year, we often think about ways to improve our lives. 2025 promises to be an interesting year, whether your goals are personal or professional. 2025 is also an important year for HVAC replacements with the introduction of the AIM Act that will officially end the use of outdated HFC refrigerants. If your HVAC is approaching the end of its lifespan, 2025 is the ideal year for an upgrade to a more efficient system using more eco-friendly, accessible, and affordable coolant fluids. You will also gain the advantage of the many technological advancements made since your old HVAC was installed.

Is now the right time to replace your HVAC? Let’s look at the 5 key signs that your HVAC is ready for an upgrade in 2025 and how the AIM Act may influence your decision.

1. Your System Is Over 10–15 Years Old

The average lifespan of an HVAC system is 10-15 years old. Some carry on for longer but lose significant efficiency over time. If your HVAC is near this lifespan or has long since passed, it’s likely less efficient and prone to breakdowns. It may also be using an old refrigerant like R-410A which is bad for the environment and is being phased out by the AIM Act. This will make future coolant-related repairs more costly and eventually unavailable.

The AIM Act is phasing out HFC refrigerants. However, your new HVAC will feature a more eco-friendly coolant like R-32 or R-454B that will be more available and affordable to top up whenever necessary.

2. Rising Energy Bills

As an HVAC loses efficiency with age, it needs more power to operate. This can result in a slow but steady increase in your power bills from one year to the next. HVAC can represent as much as half your home’s power bill, especially as efficiency decreases. It may be time to upgrade if your power bills have been rising beyond the growing energy price.

The AIM Act can also help you here. The act requires that new HVAC models in 2025 achieve more advanced energy efficiency with high-performance refrigerants for optimal cooling with a lower environmental impact.

A high-SEER (Seasonal Energy Efficiency Ratio) system can significantly reduce your energy consumption, saving you money while lowering your carbon footprint.

3. Frequent Repairs

If your HVAC needs constant repairs, the cost of repairs can add up faster than you realize. As the AIM Act phases out older refrigerants the cost of repairs may continue to rise. Frequent repairs are costly. However, they also mean your HVAC might give out at a critical time, like in the middle of a heat wave.

Replacing your HVAC secures steady, efficient, and reliable performance all year with minimal need for maintenance during the first five years. Say goodbye to breakdowns and repairs and enjoy the peace of mind from the new warranty.

4. Uneven Heating or Cooling

Hot and cold spots in the home often indicate that your HVAC can’t do its job effectively anymore. Uneven temperature distribution can mean trouble with the blower fan or poor thermostat performance. An upgraded HVAC system offers improved airflow and advanced temperature control for even heating and cooling and whole-home comfort.

Many of the latest HVAC models are compatible with smart thermostats. They give you advanced and intuitive control over your home’s comfort, energy savings, and longer HVAC lifespan.

5. Outdated Technology and Features

You may be missing out on tech and features that have become common with newer HVAC models. 2025 introduces more smart home integration and eco-friendly designs. Putting off an HVAC upgrade can mean missing out on cutting-edge technology. This includes smart home controls, remote monitoring, and improved air filtration.

The AIM Act has also accelerated innovations in HVAC, ensuring that models are better for the environment and provide efficient, enhanced comfort.

How the AIM Act Impacts HVAC Upgrades

The AIM Act (American Innovation and Manufacturing Act) addresses the phasing out of hydrofluorocarbons (HFCs), such as R-410A. These were once commonly used as refrigerants but have a high global warming potential (GWP).

In 2025, the AIM Act will take effect, reducing the availability of these refrigerants which will drive up the cost to repair older systems that use them. If your HVAC falls into that category, upgrading this year will save you from costly repairs while gaining access to the new system’s efficiency, comfort, and carbon footprint reduction.

These upgrades meet federal regulations and offer long-term savings and environmental benefits.

Upgrade for Efficiency, Comfort, and Compliance

If your HVAC is losing efficiency, often breaks down, or is over 10 years old, 2025 may be the perfect year for an upgrade. The AIM Act ensures that all new models are more efficient, eco-friendly, and ready to provide long-term cost savings and comfort to your home.

Don’t wait for your system to fail or for a high-cost repair. Plan your HVAC upgrade this year. Contact us today to schedule a consultation and discover the perfect solution for your home’s heating and cooling needs.

Knowledgeable, quality work.

I had an AC issue the day before Thanksgiving but Ramon was able to come the night before and get me up and running again. He was incredibly professional and personable. He let me know I desperately needed the UV light installed in my system. We went ahead and scheduled everything for a Friday install. My technician, Alex, came out earlier than expected (not complaining at all) and got everything cleaned and installed in no time. Professional and efficient. Both guys were amazing. A big thank you to both Ramon and Alex.

For those looking for a reputable AC company. We have been using Aztil for many years, as has my daughter n a few neighbors and friends. We had a loud noise coming from our air conditioner inside our house. We called aztil, and was told somebody would be at our house between 1 and 4:00 that same day.

I received an email and a phone call from Dana saying what time he would be here. Dana showed up at about 1:30, and promptly got to the issue. We needed a new inside fan, Dana got on the phone to the office, and then let us know that they had a fan and he was going to get it and he would be back.

He left and came back within a half hour 40 minutes and proceeded to put in the new fan. He changed our filters and asked if we had any questions.

Dana did a GREAT job and made sure we were happy. He was very polite, neat n clean and courteous. Could not ask for a better service call tech.
Aztil is GREAT and I highly recommend them.
This morning, the battery for my AC system died, and when I looked at my thermostat the entire screen was blank. I started panicking because I couldn’t figure out what to do or how to replace the battery. My neighbor recommended Aztil Air Conditioning, so I called them right away. I spoke with the customer service manager, Sabrina, and she was truly incredible. She had me send her a picture of my thermostat, and then she personally walked me through the whole process step-by-step all through her own number. She was patient, kind, and made sure I understood everything. What really surprised me was that she didn’t charge me at all for the help. She told me she didn’t have to charge because she was able to guide me through it over the phone. That level of honesty and customer care is extremely rare.

Sabrina went above and beyond for me this morning, and I am truly grateful. I highly recommend Aztil Air Conditioning to anyone looking for a company that truly cares about their customers. Thank you again, Sabrina!
Nico was excellent. Full explanation of services. I would like to get him for any future services. I'd like to add that I was pleased with the vent cleaning that was performed by Alex Molina and his assistant.
Response from the owner:Hi Jazziz, thank you for your kind words! We're so glad to hear that Lazaro did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
