FAQs about HVAC Maintenance

Keeping your HVAC system running is crucial for ensuring it works efficiently, providing comfort throughout the year. Regular maintenance not only lengthens the life of your HVAC system but also helps to reduce energy costs and preventing costly repairs. Here are some frequently asked questions about HVAC maintenance.

Why is HVAC maintenance important?

HVAC maintenance is essential for several reasons:

  1. Efficiency: Regular maintenance ensures that your system runs at peak efficiency, which can reduce energy bills.
  2. Longevity: Proper care can extend the lifespan of your HVAC system, delaying the need for expensive replacements.
  3. Air Quality: Maintenance helps keep your air clean by ensuring filters and ducts are in good condition.
  4. Prevention: Regular check-ups can identify and fix minor issues before they turn into huge, expensive problems.

How often should I service my HVAC system?

It is recommended that you have your HVAC system serviced at least twice a year – once before the cooling season (spring) and once before the heating season (fall).

This bi-annual check-up ensures that both the heating and cooling components are in good working order before they are needed most. Apex Clean Air is a company that specializes in HVAC maintenance and servicing.

What does regular HVAC maintenance include?

A typical maintenance check-up includes:

  3. Inspecting the thermostat: Making sure the thermostat is functioning correctly and calibrated.
  4. Lubricating moving parts: Making sure all moving parts are well-lubricated to prevent wear and tear.
  5. Checking system controls: Verifying that the system starts, operates, and shuts off correctly.
  6. Tightening electrical connections: Ensuring all electrical connections are secure and inspecting the system for potential electrical issues.

Can I perform HVAC maintenance myself?

While homeowners can handle basic maintenance tasks like changing filters and keeping the exterior unit free from debris, it’s recommended to have a professional perform more detailed inspections and maintenance.

Professional HVAC technicians have the knowledge and equipment to thoroughly inspect and service your system, ensuring it operates safely and efficiently.

Can I improve my HVAC system’s efficiency?

Improving the system’s efficiency involves the following:

  1. Regular filter changes: Replace filters every 1-3 months to maintain good airflow and reduce stress on the system.
  2. Sealing leaks: Make sure your home is well-insulated and seal any ductwork leaks to prevent air loss.
  3. Using a programmable thermostat: Programmable thermostats help optimize heating and cooling schedules, reducing energy use when you’re not home.
  4. Keeping vents clear: Ensure that vents and registers are not blocked by furniture or other objects to allow proper airflow.
  5. Scheduling regular maintenance: Regular professional check-ups keep the system in top shape.

Are there any signs I should look out for that my HVAC system needs repair?

Common signs that your HVAC system may need repair include:

  1. Unusual noises: Banging, clanging, or screeching sounds can indicate mechanical issues.
  2. Inconsistent temperatures: Difficulty maintaining set temperatures or uneven heating/cooling.
  3. Increased energy bills: A sharp spike in energy costs without increased usage.
  4. Frequent cycling: The system frequently turns on and off, indicating potential issues with the thermostat or system capacity.
  5. Poor air quality: Increased dust or humidity levels in your home.


Regular HVAC maintenance is important for making sure your system operates efficiently, safely, and effectively. By staying on top of routine maintenance, you can extend the life of your HVAC system, improve indoor air quality, and lessen energy costs.

While some basic tasks can be performed by homeowners, it’s essential to schedule professional maintenance twice a year to address more complex aspects of your system. Being proactive about HVAC maintenance will help you avoid unexpected breakdowns and make sure your home remains comfortable throughout the year.
