Most Common HVAC Problems

Your HVAC system comprises nearly forty percent of your home’s annual energy costs. Its ability to heat and cool your home efficiently is an essential part of providing a comfortable living environment for you and your family.

Unfortunately, your heating and cooling system has an enormous workload. As such, it can be subjected to daily wear and tear, particulates, and mechanical malfunctions that threaten its ability to efficiently regulate your home’s temperature. While it would be wonderful to be able to maintain and repair your unit on your own, the complexity of home HVAC systems necessitates professional repair services to keep them running smoothly and safely year round. Fortunately, finding repair services 24 hours a day, 7 days a week in most areas isn’t a problem. You can assist your professional HVAC technician by learning to distinguish its efficient function from some more common causes of breakdown. Here are some of the most common HVAC problems that indicate your need to call in a professional.

Clogged Condensate Lines

Your air conditioner will create condensation as it works to cool hot air and circulate it through your home. A condensate line is a tube that helps to remove excess water, allowing it to drain outside your home. At times, these lines can become clogged with sludge, debris, and other substances that cause water to pool inside your unit. Over time, this standing water could negatively impact ielectrical components, the blower motor, and other parts that are needed for it to function well. Regularly monitor your condensate drain line to see if it is draining water as it should be. If not, call in a technician to address the dry line and possible water backup.

Continuous Blower Fan

If your fan is consistently blowing, attempting to circulate air, it means that your system is working harder than it should to cool your home. Check your thermostat to make sure the “fan on” setting is not on, and if the problem persists, you may need to call someone to address the cause of the issue.

Dirty Evaporator Coils

Evaporator coils are responsible for turning refrigerant from liquid to gas. Once the refrigerant is in its gaseous state, it is able to absorb heat from surrounding air, helping to cool your home. These coils frequently become blocked with dirt and other debris, preventing air from reaching your heat exchanger. These evaporator coils will have to be cleaned in order for your unit to begin efficiently cooling your home again. If you feel like you are able to do so, use a system-approved cleaner to saturate coils, then wipe them clean with a soft cloth or brush. As evaporator coils are easy to bend, it may be a better idea to have them professionally cleaned and treated to avoid additional repair or replacement charges.

Low Airflow

The key to optimal cooling is efficient airflow. If your system is circulating air poorly, your unit will work harder than necessary, reducing efficiency and placing you at risk for system failure. Quite often, the cause of inefficient airflow is a dirty air filter, which is easily replaced. Get in the habit of checking and replacing air filters monthly to improve efficiency and cooling while reducing stress on your HVAC system.

Poor Air Quality

Poor indoor air quality is one of the most detrimental issues associated with HVAC malfunction. Especially prevalent in old, outdated, or poorly maintained systems, these bacteria-saturated systems can cause significant health issues if the cause of toxic build-up is not corrected. Contamination can lead to dangerous levels, leading to issues such as:

• Dizziness and lethargy
• Eye and skin conditions
• Headaches
• Respiratory issues
• Allergies

Consider an upgrade to an allergen-resistant airflow system, and commit to changing your filter regularly to reduce the buildup of toxic allergens, bacteria, and particles. You’ll breathe easier, you’ll feel better, and your unit will work more efficiently.
