There are a lot of things that can go wrong with an air conditioner. Trouble with HVAC air flow is the most common one. There may be hot and cold spots in your Bay Area house. Closing one door could cause another room to become stuffy from air pressure issues. These are a few possible causes of HVAC airflow issues in the house.
1. Clogged Air Filter
Changing the air filter is a small task. However, many people overlook it. The effects of ignoring a clogged air filter are not small. They can cause severe damage to your equipment and indoor air quality. Your air filter is probably clogged with small particles, such as dander, dust, pollen, and hair if you haven’t replaced it or cleaned it recently.
There could be mildew and mold spores as well. Air can flow more easily and efficiently through the vents when you change the filter. This can save you a lot of money and improve your home’s indoor air quality. Experts recommend changing air filters every 3 months or whenever they get dirty.
2. Clogged Coils Need Cleaning
HVAC coils can get clogged if the system has not been cleaned in a long time. Dirt can quickly accumulate on the coils that prevents the evaporator and condenser coils of the system from doing their job. Dirty evaporator and condenser coils are to be blamed if the system is unable to complete its job. Regular maintenance can prevent your system from requiring major repairs. This is not a DIY task. You should have a trusted HVAC provider tune-up your system regularly.
3. Blocked or Defective Ducts
Ductwork may get blocked or choked with dust, debris, dander and other things if you haven’t had it professionally cleaned in a long while. This is more likely if the air filters are not maintained, cleaned, or replaced in time. A more common issue than blocked ductwork is leaky ductwork. There are numerous points in a ducting system that can fail to cause uncomfortable effects. These are a few things that can go wrong with the ductwork:
- Improper installation
- Old ducts and materials
- Pest damage
- Unlicensed repairs
- Shortcuts taken by amateur HVAC technicians
You should have both structural and blockage problems diagnosed and resolved by a licensed HVAC professional.
4. Blocked Vents
It’s vital that you keep all the vents in your home open and unblocked. Closing vents may actually cause more harm than good. It can cause your utility bills to fluctuate. It can also cause cold spots or uneven cooling in the house. Even the smallest blocked vent can create a chilly or stuffy room. Fortunately, all you need to do in this case is inspect your house for any blocked or closed vents. Make sure there is no furniture or draperies blocking the vents.
5. Improperly Sized HVAC Unit
It is important that you purchase an HVAC unit that is adequate for your house. It should not be too big or small for the area. Oversized unit may short-cycle, which refers to an air conditioning unit turning on and off too quickly. This can cause a lot of issues, such as excess humidity, premature failure, or uncomfortable heating.
