How can you improve the efficiency of a residential HVAC system?

Regular maintenance is essential for improving the efficiency of a residential HVAC system. This process involves a series of tasks aimed at ensuring that all components of the system are functioning optimally. During maintenance, technicians can clean filters, check refrigerant levels, inspect ducts for leaks, and ensure that all parts operate as intended. Regular maintenance helps to prevent breakdowns, prolong the life of the equipment, and maintain its efficiency, ultimately leading to lower energy consumption and costs.

In contrast, while increasing duct size could potentially improve airflow, it might not always be necessary or effective and could lead to other complications such as improper system balance. Higher refrigerant levels could indicate overcharging, which is detrimental to efficiency and can cause system malfunctions. Installing additional units may also not be the most efficient solution, as it could lead to higher upfront costs and increased energy use without addressing existing inefficiencies in the current system. Regular maintenance, therefore, stands out as a proactive and effective approach to ensure that HVAC systems run smoothly and efficiently over time.
