Programmable Thermostat Benefits

Customization: Users can control heating and cooling around daily schedules. You no longer have to adjust temperature or thermostat controls up or down to accommodate an active, empty or sleeping house. And, if you are going away for the weekend, or longer, one touch to “Away Mode” provides the perfect setting.

Convenience: This is linked with customization. You don’t even have to think about your heating and cooling. No need to wake up in the middle of the night and wonder if you adjusted the thermostat setting in order to conserve a bit of energy. You won’t be distracted while away from home, kicking yourself about all the money you may be wasting with the air conditioning or heater going full blast for absolutely no one.

Conservation: If you are on board with conserving energy, this is a thermostat that will make you proud. The “setback temperature” control feature let’s users program an energy saving temperature for an empty house. The smart feature of the device anticipates your arrival and steps up performance at the right time. When you enter, your home won’t be too warm or too cool. It will be just right and back on track with the temperature setting for an active home.

Cash: Energy savings, of course, translate in to saving money as well. But this thermostat goes a step beyond savings through temperature control. It is smart enough to know when to switch between gas or electric operation for maximum savings. Now that is truly smart.

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?
