Staying in a stuffy room is an option. But I’m sure you wouldn’t like to be in such a situation, right? Well, a room with poor airflow can cause you problems.
For example, did you know you’re at higher risk of experiencing respiratory problems or allergic reactions if you stay in a stuffy room or house?
So, in this article, get to learn more about airflow in a room and how to increase its quality.
Importance of HVAC system airflow in your room
1. Control impurities
You might worry that your home’s overall airflow quality isn’t good, especially if you stay in the busy city center. But in most cases, your home’s inner air can be unclean compared to the outer air. However, a friendly ventilation system will expel buildups of bacteria, moisture, unpleasant odors, and pollutants from your indoor air.
2. Air regulation
Unless you’ve set up a friendly ventilation system in your home, you won’t be able to control the ideal temperature and airflow within your room or building. More quality airflow means you’ll have to put up with high energy bills. And for that reason, adequate ventilation helps you control your room’s air while operating in line with the necessary health and safety requirements from the national comfort institute.
3. Stop condensation
Condensation leads to rotten and mold surfaces that, typically, you have to avoid. Also, condensation and damp conditions can cause health issues like allergic reactions and, for some, respiratory problems. However, ensuring you’ve set up an adequate ventilation system will help lessen these risks.
4. Reduce temperatures
If you confine yourself in a room with a couple of family members or friends, the room quickly becomes stuffy and hot. Well-ventilated rooms are more comfortable, creating a better-relaxed environment.
5. Health benefits
Another purpose of an adequate ventilation system is the beneficial effect on your well-being and health. Indoor air pollution mixed with inadequate ventilation can cause several health problems—for example, allergies, asthma, rashes, sinusitis, and headaches. However, you can avoid such health complications by installing an adequate ventilation system.
Symptoms of Weak HVAC Air flow
1. Hot and cold spots
If you’ve set the same thermostat settings throughout your home, you might be asking yourself why particular rooms have cool air while others have warm air. Well, temperature variations in a house are a vital sign, suggesting something is wrong with the HVAC airflow.
2. Weak HVAC Airflow coming from vents
You’ve set your HVAC unit on its lowest settings, but the room still has hot air, and you hardly feel any air circulating within your house. So, you decide to place your hand under the HVAC vents but feel no air circulating; this indicates there’s an HVAC airflow problem.
3. Pressure Imbalance
If you’re experiencing a few air drafts on the upper floor of your house that you can notice when your doors rattle or shut on free will, you may be dealing with uneven pressure as a result of poor airflow.
4. Hot air from the Air conditioning unit
When your AC unit starts to blow hot air when it’s above 100F outdoors, you will have to deal with a poor HVAC airflow problem that you need to fix soon to prevent additional damage.
5. Registers expelling little to no air
If your room on the upper floor is kind of stuffy, or if you place your hand near the supply registers and feel there’s barely a trickle of air, then that’s an indication of airflow problems. Occasionally, the aircon runs, but no air comes from your vents.
6. Compressor failure
Airflow problems that go unattended for long periods cause compressor failure; this is quite an expensive repair, and you’ll cough up a few dollars to repair the unit.
Common Causes of Low Air flow in a Room
Closed damper valve
Your thermostat can automatically control the dampers. So, if your aircon has an automatic damper system, you might need to check the dampers if they’re stuck. Moreover, if the dampers operate manually, wrong positioning might cause the issue. You can locate them in the ductwork to see if they’re in the proper position.
Wrongly Sized Air Conditioner
If you decide to get an oversized aircon, don’t assume it will be more efficient when cooling your room or home. You’ll be wrong because an air conditioner larger than the size you need will increase wear and tear. Moreover, the aircon won’t give you the sufficient airflow you need as it won’t work long enough to reduce excess moisture in your room or home.
Dirty Outdoor Unit
Leaves are common debris that quickly gets stuck to the air conditioner’s outside system, mainly if some shrubs or other leafy plants are covering it up. Regrettably, the air conditioner will have to operate harder to spread the heat, negatively impacting your room’s airflow. Also, a weak airflow can overheat the HVAC system. It would help if you cleaned your aircon regularly to prevent such issues in the future.
Thermostat Problems
If you’ve checked the aircon, but you still can’t figure out what the issue is, then it’s time you look at the thermostat. There may be no connection, but if you haven’t calibrated it correctly or there’s a malfunction, it can negatively impact your HVAC unit’s airflow.
Dirty Coils
The HVAC unit works by transporting air over cold evaporator coils. As a result of that movement, it cools your room. However, if the air conditioner has dirty coils, expect problems. When dirt covers the coils, they won’t release heat. Hence, the airflow from the aircon decreases. The aircon will have to overwork for it to cool your room and can prompt compressor failure.
Blocked or closed air vents
If you notice the air vents aren’t blowing air in your room, then something has blocked the vents. Most of the time, we block vents unknowingly; it might be a piece of furniture in front of them, or we might have shut them down on a cold day and forgotten to reopen them again.
Obstructed Condenser Unit
Usually located on the outdoor air conditioning system, the condenser unit plays a role in your home’s airflow. And if leaves, vegetation, and debris build up around the condenser unit, they will affect your home’s airflow. If you’ve put the condenser unit in a mechanical space, other items you’ve stored there might obstruct it. Clearing the obstruction may solve the problem.
Clogged Air Filter
If you’ve continuously ignored maintaining your HVAC system, clogged air filters will affect your home’s heating and cooling system. Air filters improve air circulation in your room. They clear out pollen, mold, pet dander, dust, and other airborne contaminants. If debris blocks the air filter, you’ll have stale air instead of fresh air in your room. In short, poor airflow will lead to poor indoor air quality. Moreover, a dirty filter can stop an HVAC system from working. Hence you’ll have to look for HVAC services from a professional.
Low refrigerant levels
The refrigerants in our HVAC systems improve air circulation in the room or house. And if they’re low, they won’t maintain the conditioned air coming out of the air handler. Most of the time, leakages lead to low refrigerant levels in air conditioners. The cracks or holes in air handlers can also lead to leakages. Moreover, if we fail to maintain our HVAC systems, corrosion buildup can also cause low refrigerant levels.
Clogged ducts
The ductwork in your cooling system or heating system delivers cold or warm air around your house. So, over time, no maintenance caused clogging in the ductwork. Also, it may create cracks and holes, causing reduced airflow.
Old HVAC Unit
If there’s a severe decrease in airflow from the air conditioning system, the unit’s end is closer. In old age, an HVAC system won’t operate efficiently and boost airflow. An HVAC equipment typically runs efficiently for about 10-15 years. So, if the HVAC system is above ten years, consider replacing it with a new air conditioning unit. Have an HVAC equipment pro look at it before you do a replacement.
Ceiling fans/booster fans not working
The fans on your HVAC system push fresh air via the ductwork towards your room or house. Without enthusiastic fans, the airflow from the HVAC unit reduces. Excessive dust on fan blades and faulty blower motor decreases your conditioned air.
How To Increase Airflow To One Room
I’m sure you know how frustrating it can be if your HVAC system isn’t functioning well on a warm summer day. A below-average or faulty HVAC system not only affects your home’s comfort levels but also leads to high bills since it’s operating extra hard to maintain the preferred temperature. Here are some straightforward ways you can increase airflow:
1. Regularly clean your air conditioning unit’s air filters
To lower the likelihood of dust or debris accumulation on your air conditioning unit parts, make it a routine to clean the HVAC system’s air filters. Otherwise, brace yourself for airflow restrictions.
2. Check the air conditioning unit’s vents for obstruction
For you to improve airflow within your home, you’ll have to move away from any drapes or furniture blocking the vents. While checking the vents within your house, take a piece of fabric and wipe out the dust from the vents’ grills.
3. Fix any holes and leaks in the duct system
Leaks allow more air to break out, which drops pressure within your air conditioning vents, resulting in lessened amount of air within your home. You can assess the leaks on your own or call an HVAC technician as sometimes, you can find it hard to find the leaks without special tools or equipment.
4. Regularly clean the ceiling fan
To increase fan speed, regularly clean the air conditioning unit’s ceiling fan using a soft cloth. In turn, you’ll improve your home’s cross ventilation and amount of air.
5. Schedule regular air conditioning tune-ups
Regular Aircon tune-ups help the system to run smoothly, increasing the amount of air within your home. And weak airflow within your room or house signifies some issues with your air conditioning system. So, when an HVAC pro does regular tune-ups to your system, he can be able to identify a problem before it erupts.
