When the airflow from your AC starts to drop during the heat of a Van Nuys summer, the problem can go beyond just simple discomfort. Poor airflow doesn’t always mean your entire system is broken, but it can definitely impact indoor comfort, room temperatures, and how well your AC keeps things cool throughout the house. Maybe you’ve noticed one room staying warm while the others cool just fine. Or perhaps the unit runs much longer than usual without giving you the relief you expect. These are common signs that something is off with the airflow in your air conditioning system.
Homeowners in Van Nuys often find themselves adjusting the thermostat repeatedly, thinking it will solve the issue. Unfortunately, an airflow problem won’t go away on its own, and trying to ignore it can make things worse. Air must move freely and properly throughout the ductwork to keep your home consistently cool. When something gets in the way inside the system or throughout the duct network, your AC can’t do its job efficiently. Getting ahead of airflow problems saves time, cuts down on energy use, and helps your system last longer.
Common Causes Of AC Airflow Issues
Several things can cause restricted airflow from your AC, and knowing where these problems usually show up helps homeowners in Van Nuys spot them earlier. Many of these issues are tied to regular wear or simple routine checks that get overlooked during summer months. Some problems may seem small at first but can turn into larger headaches if left alone.
Here are three of the most common causes of low or uneven airflow:
– Blocked or dirty air filters: Probably the easiest place to start. If your air filter is covered with dust or debris, the air can’t pass through the system like it should. This slows everything down and makes your AC work harder than it needs to. It can also affect how well your home filters out allergens or dust particles.
– Leaky or disconnected ducts: If the air is escaping inside your walls or attic before it reaches the vents, you’re cooling areas of your house that no one lives in. Leaky ducts are a hidden problem many people don’t catch until comfort levels drop or bills increase.
– Frozen evaporator coils: When moisture around the coils freezes, it can block airflow altogether. This issue can be caused by limited refrigerant, dirt buildup, or running the system when it’s already struggling to keep up with cooling demand.
Van Nuys homes that haven’t had a routine AC check-up in a while are especially prone to these issues. For example, one homeowner in the area noticed the front of their home was cooling just fine, but the bedrooms in the back were always muggy. It turned out that an air return filter hadn’t been replaced in months, and two duct sections had split open inside the attic. Heat buildup in the ducts only made matters worse.
Even with a fairly new AC unit, these types of problems can happen and reduce the comfort indoors quickly. Understanding what causes airflow blockage is the first step to keeping things working like they should.
Diagnosing AC Airflow Problems
Figuring out what’s causing poor airflow doesn’t always require tearing your system apart. When comfort drops, you can start with a few basic checks around your Van Nuys home. Usually, signs of airflow trouble are easy to notice and track down with some simple steps.
Start with these:
- Check the air filter. If it looks dirty or clogged, replace it. Try checking it once a month during the summer. A clean filter not only keeps air moving but also helps protect the rest of your system from dust buildup.
- Inspect the ductwork where you can see it, like in the attic or garage. Look for loose connections, peeling duct tape, or sections that have collapsed or sagged. If a section feels soft or dusty where it shouldn’t, that could be a leak.
- Evaluate the vents and registers in each room. Are they open and unblocked? Sometimes furniture, rugs, or curtains can block airflow without you realizing it. Make sure nothing is sitting over or in front of your vent covers.
If doing these quick checks doesn’t solve the problem, your system might have something going on deeper in the ductwork or inside the unit itself. At that point, it’s better to stop guessing and let our professionals take a look. A quick assessment from someone trained in HVAC maintenance can identify the blockage or mechanical failure faster before the issue turns into a full repair call.
Solutions For Improving AC Airflow
Once you’ve ruled out the basics, the next step is choosing the right solution based on what’s going wrong. If your AC isn’t moving air the way it should, kicking the problem down the road can lead to bigger issues or even full system failure. Whether the cause is buildup inside your ductwork or your equipment is overdue for service, addressing airflow problems in your Van Nuys home early will help keep cooling costs down and comfort levels up.
Here are some proven ways to improve AC airflow:
– Regular AC maintenance: Seasonal tune-ups can help extend the life of your system and keep it operating at peak performance. Maintenance includes cleaning internal components, checking refrigerant levels, testing safety controls, and making sure all moving parts are working properly. Skipping maintenance can lead to dirty blower wheels, worn belts, or clogged drains, all of which can restrict airflow.
– Professional duct cleaning: Dust, pet hair, pollen, and debris can build up over time inside your duct system. If you haven’t had the ducts cleaned in years or maybe ever, this buildup can lead to blockages or limit how freely air moves through your home. A proper cleaning done by our professionals can reduce particles in the air and improve system airflow.
– Upgrading your thermostat: If your AC runs constantly or fails to keep the temperature steady, your thermostat may be part of the problem. Newer programmable or smart thermostats offer better temperature control and can even alert you to problems if the cooling cycles seem unusual. When used correctly, they can help your system run more efficiently without overworking it.
Fixing the root cause instead of just the symptoms is always the better approach. Not every solution fits every situation, but a technician can help you sort through the options based on what your AC system needs.
When To Call Our Professionals
Sometimes it’s hard to know where the line is between doing a basic check and needing expert help. Trust your instincts.

Van Nuys summers don’t leave a lot of wiggle room when your AC starts struggling, and waiting too long often means increasing the damage.
You should contact our technicians when:
– The thermostat is set correctly but rooms are still hot or uneven in temperature.
– You hear rattling, grinding, or hissing from the system while it’s running.

– You’ve inspected what you can, but the problem keeps coming back.
Calling our professionals gets you more than a quick fix. You get a full system inspection from someone who knows how all the parts work together.
