Designing Heating and Cooling Systems in Large Buildings

Have you ever wondered what goes into a heating or air conditioning system for a large office building or another large building like a mall or a school? My name is Evelyn, and I am an HVAC architect. I design heating and air conditioning systems for large, corporate buildings. Making sure that a large building with many rooms or offices is efficiently heated and cooled is a very large job and is much more complicated than simply heating or cooling a home. This blog will educate the reader on how heating and cooling jobs this large are designed and completed.

2 Troubleshooting Tips For When Your Central A/C Unit Is Not Blowing Enough Cool Air

Nicole Jacobs

On a particularly hot day, you may have noticed that the temperature inside of your house is only slightly cooler than the outdoors. Upon further investigation, you may have discovered that there is not as much cool air blowing out of your vents. If so, use the following tips to check your A/C unit for possible issues that have relatively simple solutions.

1.  Check for Foliage Blocking Airflow Around the Unit

When trying to solve the problem with the lack of cool air in your house, the first thing you should do is walk outside and look at the central air conditioning unit itself. For this step, look for any foliage that is too close to the sides and top of the unit.

In order to keep air flowing through the A/C system, the unit needs to be able to pull air in from the outdoors. If any grass, loose leaves, bushes, or even trees are too close to your air conditioner, the fans may not be able to pull in enough air to keep the airflow going.

If you find any foliage that is too close to the unit, cut the grass, remove any leaves, and trim back any trees or bushes so that there is a few feet of free space around it. 

2.  Examine and Change/Clean the Air Filter

After taking care of any foliage that is potentially blocking the airflow from the exterior of your A/C unit, the next thing you should do is to pull out and examine the air filter. If the air filter is dirty, the dust, pollen, and other particulate debris caught in the tiny holes will restrict the movement of air inside of the unit itself.

Even if the filter appears fairly clean, replace it with a new one if your model uses disposable filters. Or, if your model uses reusable filters, clean it according to the manufacturer's instructions.

After a couple of hours, the airflow in your house should increase, and the air should be cooler. 

If your unit is still blowing a reduced amount of air after using the troubleshooting tips above, there may be a more serious issue, such as a blown blower fan or damaged condenser, that will need the attention of a professional. Contact an air conditioning service to have them send someone to fully inspect your A/C unit so that they can pinpoint the problem area and discuss your options for fixing it.
