HVAC System Replacement Benefits

Carrollton Heating and Air Replacements

All Carrollton residents know just how important it is to keep our HVAC systems fully operational all-year-long. They keep us cool and dry throughout the summer and they keep the cold at bay during the winter. Unfortunately, we also know that these complex systems don’t last forever. At some point in the future, you’ll need to replace your HVAC system. Even though you may not know when you need to replace your system, we’re here to help. If any of these symptoms ring a bell, you should prepare to replace your HVAC system.

When to Replace Your HVAC System

  1. Persistent Issues – If your heating and cooling system frequently needs to be repaired, you may be better off replacing it. As heating and cooling systems age, they will need repairs much more often.
  2. Over 10 Years Old –HVAC systems that surpass the 10-year mark are nearing the end of their life. HVAC Systems don’t last more than 15-20 years, and they require more costly repairs as they age.
  3. Major System Failures – If your HVAC has a major system failure, like a faulty compressor or motor – consider replacing it. It is typically more cost-effective to replace an HVAC system altogether than to repair a major system failure.
  4. Suddenly Very Noisy –If your system starts to make loud noises (knocking, banging grinding, etc.), contact Maxwell Heating & Cooling right away. Sounds like this can point to a major issue with your HVAC. We can help you decide if repairing or replacing your unit is best for you.
  5. You’re Simply Not Comfortable – If your home’s heating and air system simply can’t keep you comfortable, you might want to replace it. Almost all airflow, humidity and temperature issues can be remedied with an HVAC upgrade.
  6. Always Running – Your AC and heater shouldn’t run all the time. If they do, you might want to replace your system entirely. Old, worn-out systems have to work much harder to keep your home at the ideal temperature.

SEER2 vs SEER Explained

By Michele Smith • May 15, 2025
If you're in the market for a new HVAC system, you may have noticed new terms popping up—SEER2 ratings and A2L refrigerants, to name a couple. At Maxwell Heating & Cooling, we want to help our customers in Carrollton and the surrounding areas make informed decisions, so let’s break down what these changes mean and why they matter for your comfort and energy savings. What is SEER? SEER stands for Seasonal Energy Efficiency Ratio, and it's been the standard measurement for air conditioner and heat pump efficiency for decades. A higher SEER rating indicates greater energy efficiency. For example, a 16 SEER system uses less energy to cool your home than a 13 SEER system. Introducing SEER2 Beginning in 2023, the Department of Energy introduced SEER2—a new testing standard that better reflects real-world conditions, including external static pressure in ductwork. SEER2 uses updated testing procedures that are more stringent, meaning the ratings are slightly lower than traditional SEER values for the same equipment. In short, SEER2 is not a different product—it’s a more accurate measurement of how that product performs in the real world. For example, a unit previously rated at 16 SEER might be rated closer to 15.2 SEER2 under the new testing method. Why the Change? The SEER2 standard ensures that homeowners get a more realistic picture of how efficiently their system will run under typical installation conditions. It's all about transparency and long-term energy savings. What Are A2L Refrigerants? In addition to changes in efficiency standards, 2023 also ushered in a shift to A2L refrigerants. These are mildly flammable, low-GWP (global warming potential) refrigerants that are better for the environment than older options like R-410A. A2L refrigerants are part of the HVAC industry's move toward more sustainable and climate-friendly solutions. How SEER2 and A2L Work Together As manufacturers adapt to A2L refrigerants, they're also designing new HVAC systems that meet SEER2 requirements. This combination ensures that new equipment is not only more environmentally responsible but also performs more accurately according to how it’s truly used in your home. What This Means for You If you're considering upgrading your HVAC system, you’ll likely encounter SEER2 ratings and A2L refrigerants. At Maxwell Heating & Cooling, our team is fully trained and certified to install and service this new generation of equipment. We’ll guide you through selecting the right system to match your comfort needs, budget, and energy goals. Ready to Upgrade?
