Airflow issues are among the most common HVAC problems. Some of the most common symptoms include no air/ low airflow from vents, hot and cold spots throughout your home, or warm air coming out of your AC.
Ignoring such problems can put a strain on your system and lead to compressor failures. Here are some causes of airflow problems and how you can fix them.
- Blocked Vents or Registers – The vents and registers are the spaces through which air enters and leaves the rooms in your house. Make sure your furniture or other household items are not blocking any vents. Leaving them open will not only improve energy usage, but also make sure your HVAC airflow isn’t compromised.
- Dirty or Clogged Filters – HVAC filters help to clean the dust and debris from the air in your house. If the filter gets clogged, it can hinder airflow by not allowing air to pass through.
- Leaking Air Ducts – Air ducts can leak due to damage caused by loosening of joints or connections, regular wear and tear and accidental damage. Leaks in supply air ducts can cause uneven heating and cooling. Return duct air leaks will suck in dirty air and overwork your HVAC system.
- Dirty Coils – Your air conditioner’s condenser coil helps to release the heat that’s removed from your space. A typical HVAC system has two types of coils – the evaporator and condenser coils. The evaporator coil picks up heat inside the home, and the condenser coil releases it into the outdoor air. Both coils are susceptible to dust and dirt buildup and should be cleaned to allow for optimal cooling performance and operating costs.
- Thermostat – Something as simple as a faulty thermostat can cause airflow problems. Replace any old batteries and check wire connections to make sure your thermostat is working properly.
Although HVAC airflow problems have many causes, you can mitigate almost all of them with regular HVAC preventative maintenance. Contact A. Borrelli for your annual HVAC checkup and make sure your cooling system runs effectively and efficiently all summer long.
