HVAC System Maintenance for your Home

The Many Benefits of HVAC Maintenance

Here at Maxwell Heating & Cooling, we always recommend our clients adhere to a routine HVAC maintenance schedule. When you have maintenance performed semi-annually, you can extend the life of your system. You can also make sure your system is ready to handle summertime and wintertime here in Carrollton.

There are many reasons why we promote HVAC maintenance, but there are some that stand out more than others. We’ve come up with our top 7 reasons why you should stick to a routine HVAC maintenance schedule.

Why You Should Schedule Routine HVAC Maintenance

  1. It Brings Peace of Mind. When your schedule routine maintenance before summer and winter, you can rest easy. You won’t have to worry about your system breaking down in the heat of the summer or on a cold winter’s day.
  2. It Improves Indoor Air Quality. Routine HVAC maintenance can also improve your home’s IAQ (indoor air quality).

As air moves through your system, it can gather loose dirt, particles and allergens that your filter doesn’t catch. These particles can enter your home, which will reduce the air quality. The most common indoor pollutants include: Bacteria, Dust & Dirt, Pet Dander, Pollen, Mold & Mildew. During your routine maintenance appointment, we’ll make sure your air filter is properly cleaning the air.

Reasons for HVAC Maintenance

  • It Extends HVAC Lifespan. Routine HVAC maintenance can slow the aging process of your heating and cooling system. With maintenance, your HVAC’s parts will move freely and air can easily move through the entire system. This causes much less wear and tear on your system, and it’ll last longer.
  • It Improves HVAC Safety. When homeowners ignore routine maintenance, their HVAC systems can become safety hazards. During a maintenance appointment, your technician will make sure that your system continues to be safe to operate.
  • It Saves on Repairs. During a maintenance appointment, your HVAC technician will assess your system and identify any current/potential issues. Catching and fixing issues early will save you a lot of money on repairs.
  • It Saves on Bills. Healthy HVAC systems use less energy because they don’t have to work as hard to heat or cool your home. During your maintenance appointment, we will do several things to ensure your system is operating efficiently. We will:
  • Test your system’s airflow
    • Lubricate moving parts
    • Examine the ducts for leaks, etc.
    • Test the system’s controls
    • Clean and/or change the air filter
    • Tighten any loose connections
    • Test the thermostat calibration
  • You Can Remain Comfortable. Finally, poorly maintained HVAC systems simply don’t work as well as systems that are well looked after. They have a difficult time maintaining proper temperatures and humidity levels. By having your system routinely serviced, we can ensure your system is able to keep you and your family comfortable.

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?
