  • Are all air filters the same?

    No, there are a variety of sizes and types of air filters available. It is important to select the right size for your system. We recommend that you should also look at the filter's rating. A high rating removes more particles from the air, but some can restrict airflow.


    And of course, once you have the right filter, make sure to change it on a regular basis.

  • Do I need to schedule regular HVAC maintenance?

    Yes, regular maintenance is essential to keeping your heating and A/C equipment running all year long. Routine maintenance helps prevent breakdown, ensures reliable performance, optimizes energy efficiency and maximizes your equipment's overall lifespan for years to come.

  • How can I eliminate odors in my home?

    Odors in your home can have a variety of sources, including coming from your air ducts. Dirt, dust, mold and other debris in your ducts can create a stale, musty odor in your indoor air.


    We recommend using Air Scrubbers to help improve your indoor pet smells, cooking odors and more!

  • How can I know if my indoor air is dangerous?

    f you've noticed that your allergy or respiratory symptoms go away when you're out of the house, but return when you're back inside your home, this can be an indicator of an indoor air quality issue.


    Indoor air quality can be contaminated by:

    • Dust
    • Humidity levels that are too high or too low
    • Miscellaneous pollutants
    • Mold or mildew
    • New carpeting, paint or furniture
    • Pet dander
    • Presence of chemicals
    • Smoking
  • How often should I change my air filter?

    This varies, depending on the filter manufacturer's specifications. Usually, it is recommended that your air filter is changed monthly, especially during heavy-use seasons.

  • Are loud or strange noises a common issue with HVAC units?

    Noises coming from your HVAC system can be a sign that something is wrong with your equipment. If you hear thumping, squealing, banging, rattling, rumbling, hissing, or frequent clicking, call Qualtech Heating & Cooling right away.

  • What are some causes of poor indoor air quality?

    Poor air quality can be attributed to contaminants such as particles in the air or chemicals. This issue is made worse thanks to inadequate indoor ventilation, leaky ducts or activities such as smoking inside the house.

  • What is a zoning system?

    A zoning system is an HVAC system designed to provide heating and cooling to different zones of the house. Dampers are installed in the duct system to redirect air to the specific areas it is needed. Also. separate thermostats are used to control the temperature in each zone.

  • What causes ductwork to pop?

    Popping sounds in your ductwork can be caused by movement in the ducts when airflow causes a sudden temperature change. This can be a sign that your duct system is undersized for your home.


    An undersized duct system can also cause issues such as leaky ducts and reduced airflow. This can lead to mold growth and decreased indoor air quality.

  • Why is my air conditioner freezing?

    There are numerous possible causes why your A/C system can freeze, such as insufficient airflow, dirty evaporator coils, low refrigerant level, motor malfunction, or blocked vents and registers, among others.
