Which HVAC Parts Are Most Commonly Replaced?

Keeping your HVAC system in tiptop shape is essential to avoid costly repairs, and annual maintenance can help detect worn parts that might need replacing. If some parts are on the brink of failure, a technician can spot them during regular checkups and ensure they’re replaced before any further damage is done. 

But which components will most likely require replacement? Here are some of the usual suspects when it comes to needing a new part for your heating and cooling system.

  • Blower motor: During winter, your system runs constantly, causing its hard-working fan or blower motor to wear out. Regular yearly maintenance will help you avoid major breakdowns due to an exhausted component. Your technician can spot signs of wear and tear before it’s too late.
  • Capacitors and contractors: Your HVAC system runs like a well-oiled machine, and the start capacitor gets it going while the run capacitor keeps it running. Look out for the contactor — one of the most common culprits when things go wrong with this complex machinery. Thankfully, these vital components are replaceable, and we’re here to help you restore system functionality.
  • Evaporator coils: Over time, dirt and debris can accumulate on your coils, leading to corrosion if left unchecked. Regularly cleaning them is essential for extending their life span and preserving the refrigerant that keeps things cold.
  • Air filters: Regular air filter maintenance is crucial to ensure proper airflow in and out of the home. Neglecting this can have serious consequences, such as clogged filters leading to increased energy consumption and premature wear on HVAC system components, increasing repair costs in the future. Replacing it every three to six months will keep efficiency optimal.
  • Compressor: The compressor is essential for your system’s continued performance. Replacing a faulty compressor can be costly, especially for an older HVAC system. Investing in a new unit may save you money and headaches down the line, as it can prevent further breakdowns throughout your entire cooling or heating setup.

The Importance of Routine Maintenance

By maintaining your HVAC system, you’re ensuring a consistent comfort level in your home. Regular upkeep maintains an even flow of hot or cool air to protect you from unpleasant surprises.
