There aren't many things more frustrating than an air conditioning that refuses to run. A hot, muggy home can make your space incredibly uncomfortable, which is why I have always focused on maintaining my air conditioning system. Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things. You never know, making the right changes could dramatically improve your summertime experience.
In order for an HVAC unit to run properly, there needs to be proper airflow through the system. When there is a lack of airflow, a number of issues can occur, such as spots that are always hot or cold when the HVAC unit is running, pressure imbalance in rooms that can cause doors to shut, and little to no warm or cold air flowing out of the vents. If you suspect that your HVAC system has an airflow problem, it is important to have repairs made promptly in order to prevent the compressor from failing. Some of the top cause of airflow problems within an HVAC system include:
Clogged Air Filters
One of the most common reasons that an HVAC unit experiences airflow issues is due to clogged air filters. Many homeowners change the air filter in their home and then forget about it for months. During this time, the filter can become full of dirt, dust, pet dander, and other debris, causing a complete blockage. When your HVAC system is having airflow problems, the first thing that you should do is check the air filter to see if it needs to be replaced.
Air Ducts Leaking
Homes have a series of air ducts that divert warm or cold air produced by the HVAC unit through vents inside the house. Over time, the air ducts can develop small tears, cracks, or leaks, which can lead to air seeping out. If this happens, the air flowing out of the vents may feel noticeably weaker than normal. An HVAC technician will be able to inspect your air ducts to determine if they are leaking; in the event that you do have leaking air ducts, having them repaired should solve the airflow issue.
Dirty Condenser Coils
Condenser coils are found in the outdoor HVAC unit, and they can quickly become dirty. When condenser coils are dirty, heat can't be released, so the HVAC unit has to run more in order to produce air. After an extended period of time, the HVAC unit will not be able to run properly due to the dirty coils, which can lead to airflow issues inside the house. A good way to prevent this type of problem from occurring is by having an HVAC technician inspect and clean your outdoor HVAC unit at least once a year so the condenser coils don't get dirty enough to cause problems.
