Frequently Asked HVAC Questions

When it comes to maintaining comfort in your home or business, understanding your HVAC system is essential. Whether you need air conditioning service, duct cleaning, heat pump installation, or full HVAC repair, having the right information helps you make informed decisions. Below, we’ve answered the most common questions about heating and cooling systems to help you keep your system running efficiently year-round.

  • How do I know if I need AC repair?

    Common signs you need AC repair include warm air blowing from vents, weak airflow, unusual noises, frequent cycling, high energy bills, or moisture leaks around the unit. If your system isn’t cooling properly, it’s best to schedule professional air conditioning service promptly to prevent further damage.

  • How often should I schedule air conditioning service?

    You should schedule air conditioning service at least once per year, ideally in the spring before peak cooling season. 

  • What is included in a professional HVAC repair service?

    A typical HVAC repair service includes diagnosing the issue, inspecting system components, checking refrigerant levels, testing electrical connections, cleaning coils, and ensuring proper airflow. The technician will repair or replace faulty components to restore system performance.

  • What are the benefits of regular duct cleaning?

    Benefits of duct cleaning include improved indoor air quality, better airflow, reduced strain on your HVAC system, and enhanced energy efficiency.

  • How often should duct cleaning be performed?

    Most homes benefit from duct cleaning every 3–5 years. However, homes with pets, allergies, recent renovations, or excessive dust may require more frequent service.

  • What are heat pumps and how do they work?

    Heat pumps are energy-efficient systems that provide both heating and cooling. They transfer heat rather than generate it. In summer, they move heat out of your home; in winter, they pull heat from outside air and bring it indoors.

  • How long does an HVAC system typically last?

    Most HVAC systems last between 10–15 years with proper maintenance. Regular air conditioning service, timely HVAC repair, and routine duct cleaning can extend the life of your system.

  • Why is my AC running but not cooling?

    This could be caused by low refrigerant levels, dirty coils, clogged air filters, thermostat issues, or duct leaks. A professional AC repair technician can diagnose and resolve the issue quickly.

  • How can I improve my HVAC system’s efficiency?

    To improve efficiency:


    • Replace air filters regularly
    • Schedule annual air conditioning service
    • Keep outdoor units clear of debris
    • Seal duct leaks
    • Install a programmable thermostat
    • Schedule periodic duct cleaning

  • Should I repair or replace my air conditioner?

    If your AC unit is over 10–12 years old, requires frequent repairs, or your energy bills are rising significantly, replacement may be more cost-effective than repeated AC repair. A professional evaluation can help determine the best option.

  • What are signs my air ducts need cleaning?

    Signs include visible dust around vents, musty odors, inconsistent airflow, increased allergy symptoms, or debris inside duct openings. Duct cleaning can help restore clean airflow throughout your home.

  • How quickly should I address HVAC issues?

    HVAC problems should be addressed immediately. Delaying HVAC repair can lead to system failure, higher repair costs, and decreased energy efficiency.

  • Do heat pumps require maintenance?

    Yes. Like traditional systems, heat pumps require regular air conditioning service and heating maintenance to ensure peak performance, efficiency, and longevity.
