Common Problems with HVAC Air Mixers and How to Fix Them

Due to their complexity, HVAC air mixers are susceptible to various problems over time. To avoid expensive repairs or replacements, it’s critical to understand how to diagnose and resolve issues with everything from malfunctioning thermostats to clogged filters.

Naturally, regular preventative HVAC servicing and maintenance carried out by certified service specialists is the best approach to addressing the most frequent HVAC issues. Still, an owner can effectively handle some problems. Hence, choosing the right air mixer manufacturer is always a good idea to avoid such problems.

Tips to Choose the right HVAC air mixer manufacturers

  • Leaks of Refrigerant

As mentioned above, the effective functioning of your HVAC system depends on proper refrigerant levels and unhindered flow. Even though refrigerant leaks in homes are frequent A/C issues, homeowners shouldn’t attempt to fix them. Since the refrigerant circuit is a sealed system, according to EPS regulations, only licensed and certified professionals are allowed to handle refrigerant fluid.

  • Frozen Coils for Evaporators

Ice accumulation on the evaporator coils of household air conditioners is another prevalent issue. Poor ventilation, low refrigerant, or broken HVAC parts are the causes of this. To prevent equipment damage, turn off the cooling system first. Verify that every air vent is open and unobstructed. Rather than attempting to remove the ice, let it melt. Contact your neighborhood HVAC repair company if the freezing occurs again.

  • Inequitable Allocation of Air

HVAC air mixer manufacturers frequently have uneven air distribution as a problem. This issue usually leads to hot and cold spots within a structure, which causes discomfort in certain areas. Uneven air distribution can result from a number of factors. Regularly inspect and clean the air mixer. Consider swapping out the air mixer for one that is the proper size if the problem persists.

  • Limitations on Airflow

If the heater or air conditioner is producing less air than it used to, there’s probably a simple solution to this common HVAC issue, and that is air mixer replacement. Go to the outdoor unit to make sure there are no weeds or accumulated rubbish. After that, check the vents to make sure none are blocked. If none of these measures help the airflow, the next step is to clean the air ducts. At such a point, it is best to hire expert heating and cooling services.

  • Strange Noises from the HVAC system

As unlikely as it seems, a dirty air filter could be to blame. The equipment has to work harder than it should due to obstructed airflow, which might lead to fasteners coming free. After changing the air filters, check for any loose bolts, screws, or joints. If the noise persists and your HVAC system is older than twenty years, you might want to replace the entire thing.

  • Issues with Ignition and Pilot Light

Your furnace’s ignition system functions according to a highly defined procedure. It is possible that your furnace won’t ignite if one of the parts or ingredients is broken. Burners, flame sensors, or the pilot light itself may be the source of the problem. If your furnace won’t light, it’s an issue that needs to be professionally diagnosed and fixed. Make an appointment with a qualified technician to safely handle the high-voltage electrical and gas supply.

  • Regular On/Off Cycling

Short cycling or frequent cycling is a typical HVAC issue that can have a number of causes. Check those air filters first. Next, confirm that the thermostat is operational and properly adjusted. Make sure there are no closed or obstructed air vents. Clear the area surrounding the outdoor equipment of any weeds or debris, and peer through the metal grill that protects the condenser coils. Use the grill to rinse them off if they seem unclean. The delicate condenser fins should not be bent if the grill is removed.

  • Water Seeping Through the Unit

Condensation from furnaces and air conditioners is directed toward drain pipes. Blockages in these pipes and the drains can cause water to back up and seep from the unit. Use bleach to clean the drains by pouring it down the pipes. Make a quick touch with an expert, contact us if you are unable to resolve the problem on your own.

Selecting the Appropriate Air Mixer Manufacturer

It’s crucial to choose the proper AHU air mixer manufacturer to ensure the dependability and quality of your HVAC system:

  • Reviews and Reputation: Look for vendors with a proven track record and excellent references from past customers.
  • Product Caliber: Check if the manufacturer uses high-quality materials and adheres to a rigorous quality control process.


An inefficient HVAC system may result in increased energy costs. Regular maintenance, such as checking for leaks and ensuring the air mixer is in good operating order, can increase energy efficiency. Many of these issues can be avoided with routine maintenance, correct installation, and selecting the best air mixer manufacturer, such as EB Air Control.
