Having an HVAC system is a great investment in your home or business. Besides making your house a comfortable place to live, it also adds the overall value of your home. To ensure that your air conditioning system is working correctly, it requires great care and maintenance. You should also ensure that it is in top-notch condition at all times. Like other systems you have at home, HVAC is bound to breakdown from time to time. To avoid total failure, you should be able to find and fix some of the common problems the system encounter. Below are 15 tips on finding and fixing common problems in your air conditioning system.
Finding and Fixing Common Problems in Your HVAC System
1. Low refrigerant
The refrigerant is the component that the system uses to get rid of heat and humidity from the air in your commercial or residential property. If the refrigerant lines develop leaks, you end up not having the right amount of refrigerant to cool your property. To fix the problem, you should find the leaks and repair those holes. The other option is to replace the refrigerant.
2. Frozen evaporation coils
The evaporation coils of your air conditioning are full of refrigerants that help absorb heat like a sponge. The coils require warm air circulating around for them to function correctly. In case there is a problem with airflow and the coils become extremely cold, ice can accumulate on the outside. This makes your air conditioning system ineffective in cooling your home. Make sure that regular inspection is done to ensure that coils are checked regularly to ensure they are in proper condition.
3. Dirty condenser coils
The condenser coils help get rid of air removed from the air by moving it outside your house. When the coils are covered with grime or dirt, they won’t work effectively, and heat transfer is hindered. To avoid this problem, ensure that the condenser coils are cleaned regularly to remove the dirt on them.
4. Fan problems
Your HVAC system has a fan that helps in blowing air over the evaporator coil to make the air cool. The other fan helps remove the heat from your house. The fans may fail to work effectively due to motor problems, worn-out belts, lack of lubrication and excess dirt. This leads to reduced airflow and other system problems. Make sure to do proper care through regular cleaning to ensure no dirt accumulates. Besides, you can fix the issue through proper lubrication, repairing the motor and replacing the worn-out belts.
5. Thermostat problems
In case your system has the old dial-type thermostats; it means it may be calibrated improperly, meaning your HVAC system is receiving wrong instructions from the control. You can fix this issue by recalibrating the thermostats or replacing it. With the new programmable thermostats, you can ask your AC experts to correct the thermostat’s settings.
6. Clogged drains
All the moisture removed by your air conditioning system goes to the drain. If there is clogging in the drain line, it gets full and may damage the HVAC system. The problem can also cause mold on your wall, ceilings, and furnishings. To avoid this problem, make sure that the drains are inspected and any debris removed before clogging can occur.
7. Clogged filters
Your AC filters are bound to accumulate dirt with time. This may make the coils to freeze, leading to reduced airflow. To fix the issues, make sure you inspect the filters regularly and remove any dirt.
8. High energy bills and lack of enough air
If you find that energy bills keep on going up and there is no enough air from the registers, then the ducts may be having holes. Your AC professional will help fix the issue by checking the system and repair the holes or replace the ducts with new ones.
9. Breakdown of the motor
This is another common problem with your HVAC system. When you note that the motor of your system is no longer working in the right way, the first things to check are the fuses and breakers. Fuses and breakers help safeguard the compressor and motor. To handle the problem, check the fuses and breakers and have them fixed or replaced.
10. Burnt Capacitors
You know that the compressors have problems when you note the fans are not working. The start capacitor is responsible for sending a jolt to make the motor work. On the other hand, the run capacitor gives a number of jolts to make the motor work. When the two capacitors burn, your HVAC will not run. The best way to fix the problem is to have them replaced.
11. Compressor problems
The compressor is responsible for applying energy to the refrigerant and propels it through the coils to perform heat exchange. If the compressor fails to work, the system fails to cool the house. Without the right amount of refrigerant, the compressor gets hot and eventually fails. The way to fix is to have either repaired or replaced by your HVAC expert.
12. Worn out contactor
In an HVAC system, there are contractors for the blower motor, compressor, and the condenser fan motor. They are responsible for making an electrical connection that starts the compressor and motors. In case there is pitting and arcing on them, it becomes hard for electric current to make the motors work.
13. HVAC cooling unevenly
If you realize there are temperature fluctuations in your business or home, there may be poor insulation, leaking duct or blocked registers or vents. To fix the issue, make sure all the ducts at home are clean and open.
14. Unusual noises
At times you may hear strange noises coming from the blower motor. The strange noises indicate there is a problem with the belt or motor bearing. One way to fix the problem is to add lubricant to the oil port. If you continue hearing the strange noises, call your air conditioning professional for help.
15. Tripping circuit breaker
Your circuit breaker may trip because of several reasons, with a faulty HVAC wiring being one of the causes. Faulty wiring hinders the system from getting enough power or makes the breaker to trip. The best way to have the issue fixed is to check the AC wiring and have any problem fixed by your HVAC professional.
