Top 5 Most Common HVAC Issues

Many homeowners do not have a complete understanding of their HVAC system. While it isn’t necessary to learn about these systems in-depth, it is helpful to recognize some common problems. Although the technology used to build HVAC systems have improved over the years, basic routine maintenance will always be necessary. Most of our calls are due to problems like wiring issues, leaking refrigerant, old filters, and odd noises. Luckily we have prepared a list of five common HVAC issues that should be addressed whenever present.

1. Wire and Terminal Malfunction

HVAC systems should be able to run smoothly without any interruptions. This constant operation ensures greater efficiency and productivity. When homeowners notice their unit stopping and starting repeatedly, something needs to be fixed. This symptom usually derives from wire and terminal malfunctioning. You can have a service provider inspect your HVAC system’s wiring and terminals to determine which locations are the culprit. Technicians will have to replace any areas that have become corroded over time. Fortunately, these repairs shouldn’t cost too much money.

2. Leaking Refrigerant

Refrigerant is a mixture used in HVAC systems to help aid in refrigeration cycles and heat pumps. This liquid should always remain housed in the air conditioning unit. Whenever there is a leak, homeowners will know that something isn’t working properly. Unfortunately, these leaks won’t always be visibly apparent. Constant dips in temperature can be a sign that your system is suffering from a leak. After a significant amount of this liquid has been released, the system’s compressor will overheat and stop. The compressor can also fail when too much refrigerant is used. Every manufacturer will recommend a precise amount of refrigerant to ensure that their units operate smoothly.

3. Overused Filters

HVAC systems aren’t only moving air throughout a home and regulating temperature, these systems are also filtering out harsh contaminants. Overused filters are a common problem with these systems that often gets overlooked by homeowners. The build-up of dirt, debris, and other particles can end up decreasing the efficiency of HVAC units. Older filters won’t be able to keep up with the system’s demand. Slow air movement is a telltale sign that filters have been overused. With the right filters and a general understanding of the HVAC system, you can repair this issue without the help of a professional technician.

4. Dirty Parts

Although filters are designed to trap dirt and other particles in the air, HVAC systems still require regular cleaning and maintenance. These systems are constantly running and are always exposed to harmful elements. While the components of the HVAC system should be able to withstand the accumulation of dust and dirt, too much debris could end up causing problems. From malfunctioning ACs to lower air pressure, the list of potential issues is endless. It is important that HVAC systems receive a thorough clean at least a few times per year.

5. Unusual Noises

HVAC systems are designed to run relatively silent throughout their entire lifetime. While there may be occasional noises, consistent interruptions may be a sign that something is wrong. Loud and unusual noises are indicators that something is wrong with the system’s bearings or belts. These components are constantly moving and help to provide energy to these units. Homeowners should call a technician if these loud noises persist.
HVAC systems are an integral part of every home. These appliances help to regulate air temperature and airflow throughout the year. Keeping an eye out for these common issues can help ensure that your HVAC system has a long life.

Those are some of the more common issues that lead many people to replace a perfectly serviceable system. Well-maintained HVAC systems can last up to 20 years without giving you any grief.
