Troubleshooting Fan Coils
Having your HVAC system go down can wreak havoc on your home or business. Knowing things to look for and how to do items such as troubleshooting fan coils can make this process easier and quicker to get back to normal. Learn what your fan coils do and how to verify if they are causing the issue with keeping your home or office at its normal temperature.
What are fan coils?
This part of your HVAC system is what heats and cools the air coming into your home or business location. If this unit is not working properly then you could have some major problems with regulating temperature. There are a few ways you can troubleshoot this particular area and some ideas to try to get it back in tip top shape. Most of these items are something that will be checked by your HVAC technician and they will perform these type of repairs.
Unit Running but Not Cooling
There are a variety of items that could be causing this problem. Your head pressure could be too high or too low. The suction pressure could also be too high or low and your unit will still run. For all of these you need to check the refrigerant charge to make sure it is at it's proper level. Check filters to insure they are clean and that there are no obstructions near the unit itself. It could also have a system leak and you can check that by insuring all the joints are tight.
Unit Will Not Run
Sometimes the unit and condenser itself just will not start. There are a few things that could be going on here as well. For one, your thermostat may not be level. If it is then leveling out the thermostat should fix the problem. You may not have enough power getting to the unit and will have to consider switching electrical service to insure you have enough.
Excessive Noise and Vibration
If you are noticing more noise or vibration than should typically be in the unit, there could be a few things that are not working properly. For the noise, you may find that the supply tubing length is not long enough. You may also have an improperly balanced system. This can cause noise when it's running. Other noise issues could be a dirty filter at the return. If this is the cause, simply cleaning or changing the filter should help. The vibration typically comes when your blower motor is having issues. This could be something as simple as tightening bolts or replacing the entire motor.
Your thermostat can also cause the unit to have problems. Sometimes it may be the thermostat is simply in the wrong area and can be relocated. Other times the wiring may be shorted out and needs to be replaced. These are typically a little easier to repair or fix than more of the major issues with your fan coils.
These are just a few of the areas you can troubleshoot on your fan coils when you are having issues with your HVAC system. It is critical that are the parts are maintained and cared for as this will give you a longer life of the system. Schedule regular maintenance through your HVAC Company to insure that everything is working properly.
Check these areas and see what could be the problem whenever you have a heating and cooling issue. If you are handy you may be able to handle the issue without calling out a technician. Otherwise there are some problems in the system that calling the technician out is the best idea and will save you money in the long run.
