HVAC systems can last 10–12 years. Furnaces can last even longer with proper maintenance

Your air conditioning system can freeze up for several reasons, all of which require a professional technician with the right tools and training to fix. Low refrigerant is a common cause, often due to leaks from wear and tear. When refrigerant levels drop, it lowers the system’s pressure, leading to excessive cooling that freezes the moisture around the evaporator coil, disrupting its function. Dirty evaporator coils and defective blower motors can also restrict airflow, causing similar freezing issues. If your system is freezing up, it’s crucial to have it inspected and repaired by a qualified technician.

A dirty air filter, damaged ducts, or lack of refrigerant can cause low airflow.

Changing your air filter about once a month works well for most people. However, the frequency can vary based on your environment and the presence of factors like dust, pet dander, or other pollutants. Keep an eye on your filter regularly—if it looks dirty, it's time to replace it.

Signs that it's time to replace your AC include increasing utility costs or if your AC no longer keeps your home cool

Determining the right size heating and cooling unit isn’t straightforward—it depends on several factors. The size and type of your home, insulation quality, wall materials, and attic space all play a role in the calculation. An oversized system can lead to excessive humidity, increasing the risk of moisture and mold issues, while an undersized system will struggle to keep up, driving up your energy costs. To ensure optimal performance and efficiency, consult a qualified HVAC technician to assess your home and recommend the best unit size.
