  • Air conditioning is a must if you live in Siouxland, and having your AC bite the dust on a 90 degree day can be downright unbearable. Repairs can be costly, and replacement even more so. Our list of the most common reasons for Air Conditioner HVAC issues can help you identify and possibly fix the problem, or prevent the problem from occurring in the first place.

    #1 Inadequate Maintenance

    If you can’t remember the last time you changed your filter and the words “annual maintenance” or “spring checkup” when applied to your air conditioner mean absolutely nothing to you, your AC could be on its way to a break down. The best thing you can do for your air conditioner is to have annual maintenance performed by an HVAC professional (like this guy??). During this time, the HVAC technician will able to identify minor problems before they become major repair expenses.

    #2 Dirty Filter

    If we’ve said it once, we’ve said it a thousand times – be sure to change your filter. One of the most common reasons air conditioners don’t work properly is a dirty or clogged filter. Follow your manufacturers instructions on how often to change it. A good rule to follow if you have a reusable filter is if light cannot pass through it, it’s time to clean it. Dirty filters can cause air flow restriction and there’s a possibility that your AC will freeze.

    #3 Refrigerant Leaks

    Refrigerant is a liquid that is contained within the coils of your HVAC system and makes air conditioning possible. If your AC is low on refrigerant, your unit can’t do its job and will product air that isn’t very cold. If your AC leaks refrigerant, you may be tempted to add some. Our advice: don’t. A trained HVAC technician will need to fix the leak and charge your system with the right amount of refrigerant. An undercharged or overcharged air conditioner will not operate near as efficiently as one that is charged to the manufacturer’s exact specifications.

    #4 Electrical Control Failure

    Oversizing can cause the compressor and fan controls to wear out. If your AC turns on and off frequently, this can be a sign of oversizing. During your annual spring check up, one of our HVAC technicians will thoroughly check the wires and terminals for possible corrosion along with electrical connections and contacts.

    #5 Thermostat Malfunctions

    If you’re air conditioner isn’t functioning, it’s easy to assume that it’s a problem with your HVAC system. You may be surprised that the problem could lie within your thermostat. When your thermostat is on the fritz, intermittent temperature fluctuations are common and your family’s comfort is bound to suffer.

    #6 Drainage Issues

    As the summer heats up, it’s not a bad idea to check your AC’s condensate drain. Odds are, you have nothing to worry about if your air conditioner is functioning properly. If you do encounter drainage issues and excess condensation, it could lead to some serious issues. If you notice mildew or mold growth, an increase of humidity in your home, or water around your AC, call one of our experience HVAC technicians ASAP. They will be able to identify the problem and promptly fix it.
