Preparing for colder months: What homeowners need to know about home heating

(BPT) - As the days grow shorter and temperatures begin to dip, it's time to get homes ready for the colder months ahead. Homeowners might be eager to cozy up with blankets, but it's just as important to think about the heating systems that quietly ensure warmth and comfort. From heat pumps to furnaces, these units play a pivotal role, and homeowners need to be aware of the increase in demand for these systems in the winter months.

Following are tips to help homeowners prepare their heating systems for the coming season while staying informed about changes in the industry that could impact them.

Understand how your heating works and the best option for your home's needs.

Before the cold sets in, it's prudent to take time to understand how a heating system works. Whether it's a heat pump, furnace or a hybrid system, understanding its features, maintenance requirements and overall efficiency is key. Following the manufacturer's maintenance schedule and recognizing when it's time for repairs or upgrades can save both energy and money.

For those considering switching units before winter, a heat pump is a popular option. Heat pumps offer an energy-efficient way to maintain a comfortable home by transferring heat from outside to inside, even in cooler climates. One standout advantage of a heat pump is its ability to run on electricity, often making it a more sustainable and affordable option.

For areas with harsh winters, homeowners might want to explore a dual-fuel system. This type of system combines the benefits of a heat pump with the flexibility of a gas furnace, allowing homeowners to switch between electric heat and natural gas, depending on the weather. It's an efficient way to ensure optimal comfort no matter the outdoor temperature.

Stay on top of regular maintenance.

Regular maintenance is crucial to ensure heating systems run efficiently and reliably throughout the winter months. A well-maintained system can save homeowners from the headache of unexpected breakdowns and high energy bills.

Heat pumps, for example, are relatively inexpensive to operate; however, because the outdoor unit operates year-round, it's important to keep it in top shape. Simple tasks, like keeping the outdoor coil clean, can help extend the system's lifespan and maintain its efficiency. Consulting a reliable contractor, such as a Rheem® Pro Partner, is recommended to ensure the unit receives an inspection and the attention needed for it to perform at its best.

Keep up with changing regulations.

As we head into 2025, homeowners should be aware of regulatory changes that may affect their heating and cooling systems. One of the more notable changes on the horizon is the switch to A2L refrigerants, which will replace the hydrofluorocarbons (HFCs) currently used in most systems. This transition is part of the American Innovation and Manufacturing (AIM) Act of 2020, which mandates a phasedown of HFCs due to their high global warming potential (GWP).

Starting Jan. 1, 2025, the Environmental Protection Agency (EPA) will enforce a 700 global warming potential (GWP) limit on refrigerants used in heating and cooling systems. These refrigerants, which have already been used in smaller appliances, like window units, will now be a key component of larger HVAC systems, becoming the standard in the industry.

Rheem®, a leader in HVAC innovation and a forward-thinking manufacturer, has been proactive in adapting its product lines to meet these new standards and sustainability goals. By staying informed about the A2L shift, homeowners can ensure their systems remain compliant and efficient while helping to reduce their environmental footprint.

Whether homeowners are maintaining their current unit or considering an upgrade, being informed about system options and regulatory changes can help ensure smart decisions resulting in environmental benefits and potential savings on energy bills.
