The HVAC (heating, ventilation, and air conditioning) system is of utmost importance in any home. It keeps you comfortable all year round and is necessary for your overall health and wellbeing. Like any other complex machine, unfortunately, an HVAC system can also malfunction while in operation.
If your HVAC unit isn’t working as efficiently as it should, then it’s most likely due to some underlying issues. Here are six possible issues that cause HVAC problems and how you can try to fix them:
1. Dirty or clogged air filters
One of the most common causes of poor HVAC performance is dirty or clogged air filters. Over time, dust and debris can build up on the air filter, causing decreased airflow and making it harder for your system to do its job. You can try cleaning or replacing your HVAC unit’s air filter by yourself as long as you follow the instructions in the unit’s owner’s manual.
2. Dirty evaporator coil
The evaporator coil in your HVAC unit is responsible for absorbing heat from the air inside your home. If it becomes dirty, the system’s performance suffers, and your home won’t be as comfortable as it should be. To clean the evaporator coil, turn your HVAC unit off and remove the access panel, then use a soft brush to gently remove any dirt or debris built up on the coil.
3. Leaking ductwork
You should also check for leaks in the ductworks that need to be fixed as soon as possible. Leaks allow heated or cooled air to escape, making it harder for your HVAC system to maintain a comfortable temperature in your home. You can usually fix small leaks with duct tape, but bigger ones may require help from a licensed HVAC service professional.
4. Blocked air vents
Your HVAC system will have a hard time heating or cooling your home evenly if furniture or other objects are blocking your air vents. Simply move any obstructions out of the way of the vents to let warm or cool air flow in or out of your home unrestrictedly.
5. Refrigerant leaks
Some HVAC systems use refrigerants to cool or heat the air inside the home. If you have an HVAC system that uses refrigerants, make it a point to check it for leaks. Refrigerant leaks cause the system to lose its cooling power, and you’ll need to have an expert technician fix the leaks and recharge the refrigerant levels to fix this problem.
6. Incorrectly sized HVAC unit
If your HVAC unit is struggling to heat or cool your space comfortably, it might be because it is too small or too big for your home. This might even result in your energy bills being higher than they should be despite the poor performance of your system.
Consider replacing your HVAC unit with an upgraded, more efficient model that is the right size and specs for your home. To learn more about your options, have a professional HVAC technician inspect your home and choose the right HVAC unit for your home heating and cooling needs.
The six potential HVAC issues outlined here can cause many problems in your home, from uncomfortable temperatures to high energy bills. Fortunately, most of these issues are easy to fix if you know what to look for and have the right tools.
