Symptoms of Weak HVAC Airflow problems can be identified through the following symptoms…

  • Air conditioner blowing warm air
  • Your space having hot and cold spots
  • Low airflow or no air coming out from vents
  • Pressure imbalance causing doors to slam by themselves and strange whistling sounds.

If you ignore the problem too long the strain on you HVAC unit can cause compressor failure. The compressor is the heart of your air conditioner, when it goes you will need a new unit. However the problems are easy and inexpensive to fix. We would like to list some of the most common causes and an easy way to improve AC air flow.

Obstructed Condenser Unit

The condenser unit is where the heat from your home is transferred to the air outside. Without it, the heat from your home would have nowhere to go and the temperatures would stay warm. The condenser is usually the unit you see outside of your home. In order to work properly, your condenser unit must have room to breathe. If you have any plants, trees or other obstructions that are located next to your condenser unit, they will block the airflow and make it more difficult for your unit to blow the right amount of air over the coils. Y our first step to improve HVAC airflow should be to clear the area around your condensing unit.

Clogged Filters

An air filter clogged with dust and debris will block the airflow causing hot and cold spots throughout your space. You can change the air filter once a month or consider manufacturer’s instructions and your usage to determine the interval you need to change the filter. When was the last time you changed your air conditioner’s filter? Maintenance plans are very economical way to make sure you don’t forget.

Blocked Vents and Registers

If you have a forced air heating and cooling system in your home then you have vents or registers that bring the air to the rooms in your home. These can be located on the wall, on the ceiling, or in the floor. When decorating and arranging the furniture in your home, these vents or registers can be quite an eyesore, and it can be very tempting to cover them up with couches or tables. It is important to NOT do this, however. Blocking the vents or registers can restrict the air flow and cause your furnace or air conditioner to need to work even harder to heat or cool your home. This is less efficient and more expensive.

Blocked or Leaky Ducts

What happens to all the dust that gets past your clogged HVAC filter? It winds up accumulating in the duct work. Both metal sheet duct work and flex duct work can get disconnected, preventing any air from your heating/cooling system from reaching the room. You’ll need a professional to locate the disconnected duct and seal it so that no air escapes. If you’ve got just a little air coming through the vent, the duct work leading to the room may be leaky or full of holes. This problem is actually pretty common. In a typical house, however, about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The best way to increase air flow in duct work is to have your air ducts inspected to see if a good cleaning can solve your problem or if leaks and connections need to be repaired.

Thermostat Issues

A low thermostat battery or something as simple as a faulty thermostat can cause a HVAC Problems.

Dirty Coils

Coils in your outdoor unit are exposed to the weather, debris, and who knows what else! Eventually, they can get dirty which may prevent the unit from functioning properly. This can lead to HVAC airflow issues. If you’re wondering what you can do to help prevent dirty coils, you’re in luck. Simply keeping everything at least a few feet away from the unit can help prevent leaves and other debris from falling into your unit. An air conditioning maintenance agreement includes an inspection and cleaning of the coils. Your technician will be able to monitor and help prevent issues before they turn into larger problems. A clean system runs more efficiently and can save you money.

Blower Issues

The AC blower is located inside your unit and it may be the reason for your HVAC airflow problems. The blower is the “fan” that pushes the cool air through your ducts and into your home. Sometimes, the blades begin to build up excessive amounts of dust or dirt, reducing your airflow. In this case, you should call a service technician to inspect and clean your unit. They’ll be able to diagnose the issue and get your unit working more efficiently in no time. If cleaning the blades doesn’t help, you may need to replace your blower motor. In which case, you’ll want to hire a professional to come in and handle the job. While they’re in there, they can inspect the rest of your unit and discuss any other issues they see.

Low Refrigerant Levels

This is one of the most common problems with HVAC systems, Especially if it is an older unit. If the unit is leaking refrigerant, you will notice airflow issues as well as reduced cooling. Your HVAC technician can test for leaks and repair them to get things back up to speed.
