The compressor may be running; however, the air conditioning unit may not be producing cool air. In such an instance, there may be several issues that may be contributing to this problem. You should check the HVAC unit and ensure it has been fixed. There are DIY (Do-It-Yourself) options that homeowners can utilize using certain maintenance skills. If such options fail to work, the air conditioning unit should be diagnosed further by a technician.
Below is an air conditioning repairs guide:
Before assuming the worst, make sure you have checked the common sources of the AC unit malfunctioning. You can peruse the list of common sources within a short period.
Before you begin to check the list for easy fixes, ensure you have followed the following tips to ensure the diagnostic process progresses smoothly:
- Ensure the return and supply vents are unobstructed and open.
- The doors and windows should be closed.
- The thermostat should be set cool. It should also be turned down below room temperature.
- There are AC units that have a reset button on the outdoor unit, and it is close to the refrigerant line. If you can find the button, you should push it. In some instances, simply resetting the system will solve the issue.
- The humidifiers should be turned off.
The air conditioning unit is supposed to be maintained regularly. Scheduled maintenance will help to ensure there is increased efficiency. When the HVAC system is running poorly, your electrical bill will be higher, and during summer, the temperatures will not be as favorable.
Cleaning and caring for the HVAC unit also ensures a lower chance of costly replacements and repairs; the air conditioning unit will work well, and you will not notice any major issues.
Inspecting and cleaning should be carried out at least once each month for the AC units, especially if you have thicker filters or during summer when the temperatures are high, which means the HVAC unit will be working overtime.
Adhering to such a regular air conditioning unit maintenance routine ensures it will perform well such that the product will live long and the repair costs will be lower. Each of these maintenance items ensures the unit is performing well, and the cooling and heating efficiency will improve by a certain percentage.
If you’re unable to include each of these tasks into the household routine, you can hire a licensed technician who will maintain the unit and service it regularly.
If you decide to handle such issues on your own, there are different areas of the unit that should be checked, and you should also complete such maintenance tasks. The major issues to address include:
01. Clean the Filter
The HVAC should first be turned off. The filter should then be located; it is present in the air handler cabinet. It can be easily accessed from the front door. You should consider acquiring a washable filter.
A high-quality filter can last for at least 15 years. It can last for the entire lifespan of the HVAC unit.
If ice appears around the coils, you should replace or clean the air filter, close it, and then power ON the AC unit. Ice is an indicator there is diminished airflow, and the evaporator coil cannot work properly. After the airflow is reestablished, the ice is supposed to meltdown in a few hours. The cooling capacity of the air conditioning unit will also increase in the process.
02. Cleaning the HVAC Interior
The evaporator, condenser, coil, and filters should be cleaned next. If they are clogged and dirty, the airflow within the air conditioning unit will be restricted, and the efficiency of the system will be affected in general. With time, the HVAC unit can overheat since it is overworked. Also, the compressor may be damaged, resulting in costly repairs, or you may even need to replace the air conditioning unit as a whole.
03. Checking the Electrical Wiring
The majority of the HVAC repairs are a result of electrical wiring issues. Ensure you have examined the electrical wiring within the unit. If the breaker has tripped or a fuse has blown, you should contact an electrician.
04. Check the Ductwork
The main function of the ductwork is to distribute and deliver cool air from the HVAC unit. If the ductwork is not sealed properly or cracked, the air conditioning unit will not dissipate the cool air efficiently, and you will not be aware the HVAC system is present in your home. Fortunately, the HVAC system may be operating properly, and all you have to do is inspect the ductwork to make sure it is routing the cold air to the preferred destination.
05. Checking for Refrigerant Leaks
The refrigerant is an integral part of the HVAC system. It is responsible for absorbing excess heat within your house and releasing it outside. The refrigerant is supposed to maintain this constant cycle.
The refrigerant needs to be maintained occasionally. Failure to maintain it regularly may result in small leaks. The leaks can also result because of old age. If the HVAC system is left unmanaged, the leaks may affect the HVAC system’s ability to function well.
What should you do when the air conditioning unit runs as usual, but it cannot produce cool air? You can utilize each of the DIY (do-it-yourself) techniques listed above. If the HVAC unit fails to meet your needs, contact a technician, and make sure they have checked the refrigerant levels.
Working with an HVAC Firm
If the air conditioning unit’s performance fails to improve after the maintenance process, it is time to contact an HVAC technician to diagnose the system. There are many certified technicians, and they normally work to make sure that each client’s needs have been met regarding maintenance and repairing the HVAC units. Unfortunately, there are technicians that usually take advantage of clients, and they may overcharge them.
You can ask for recommendations from your family members, workmates, or friends. Online reviews also come in handy. A good HVAC company will have numerous vocal supporters within the locality. Ensure the HVAC firm you have opted for offers emergency services, and they should also have enough technicians.
