In this article, we discuss some of the common problems that homeowners face during the summer. We also include preventative methods for a stress-free and comfortable summer season.
1. Air Conditioner Won’t Switch On
The air conditioner might not turn on because of a tripped circuit breaker. This needs to be reset before you try testing it again. Check if there is a loose plug and re-plug it properly when needed.
Also, replace the thermostat’s batteries with fresh ones. However, if the problem remains, contact a trusted HVAC technician to properly determine, diagnose, and repair the issue.
2. Air Conditioner Blows Warm Air
A central air conditioner fills your house with cold air. If it cannot do its job, it could have a clogged air filter. The dust and debris prevent proper airflow, leading to a frozen condenser. This significantly reduces the cooling ability of the air conditioner. Therefore, check the filter and replace it when needed.
3. Air Conditioner Freezing Up Outside Unit
A frozen outside unit can be because of several reasons. The refrigerant level might be low due to a leak. It could also be caused by a faulty blower motor or insufficient airflow. Have a technician check the unit to prevent this problem from happening.
4. AC Refrigerant Leak
The refrigerant is your air conditioner’s lifeblood. Leakages can lead to efficiency and functionality problems. It will also lead to higher energy consumption, uneven cooling, frozen coils, and a damaged compressor. A professional should conduct regular air conditioner inspections to ensure any coolant leaks are caught and fixed immediately.
5. Air Conditioner Makes Odd Noises
An air conditioner emits a constant low hum during normal operations. However, unusual air conditioner sounds can point to different AC problems. For instance, rattling can be due to loose components, clicking sounds can be because of relay problems, and buzzing points to electrical issues. A professional HVAC tech will know the problem when they hear the sound your air conditioner makes.
6. Evaporator Coil Gets Frozen
Constant airflow is required to prevent the evaporator coil from freezing. If this happens, the entire coil needs to be checked for clogs. The reason behind the blockage could be dirty HVAC filters, clogged vents, or a broken fan. Clean and maintain your system periodically to prevent this issue.
7. Electric Control Failure
Air conditioners need to operate steadily to ensure optimal function. However, frequent cycling can happen, and this leads to faster component wear and tear. Parts that are especially affected include the compressor, blower motor controls, and fan motor. This can also cause electric control failure, which will keep the affected components from responding.
8. Air Conditioner Leaks Water Outside
Your air conditioner also removes the excess moisture in the indoor air through condensation. This moisture is drained via a drain channel that can get blocked or damaged. When this happens, the water can end up leaking. Other causes of water leaks include a broken condensate pan and incorrect unit installation. A professional can help find the reason behind the leak and fix it.
9. Drainage Problem
When the water is not drained correctly, there will be stagnant water in your cooling unit. This encourages mold, fungi, and bacteria to grow. Also, as time passes, an unpleasant odor will spread throughout your house. This makes staying inside unbearable and unhealthy. Expert technicians will need to conduct a thorough inspection and AC maintenance to eliminate the issue and prevent it from happening again.
10. Sensor Problem
Thermostats are equipped with sensors that check the ambient temperature. It triggers your air conditioner to turn on when it gets too hot and turn off when the set temperature is reached. If the thermostat is placed in the wrong spot, it can lead to faulty readings. Fortunately, an expert can help ensure that the thermostat is placed in the correct location. They will also calibrate it to ensure it is fully functional.
Easy Steps To Prevent Air Conditioner Problems
Some of the things you can do to prevent cooling system problems are:
- Check the HVAC filter: Manufacturers recommend that air filters be replaced regularly. It is one of the best ways to avoid many common problems that an air conditioner experiences. Replacements are typically done every month or every three months. However, if you see that the filter’s surface is dirty, you can replace it ahead of the scheduled date.
- Clean the condensing unit: Since it is located outside, it is vulnerable to dirt and elements. If the coil gets dirty, it cannot release the heat outside as effectively. The surfaces need to be cleaned periodically. Remove any twigs, leaves, and trash trapped within it.
- Remove anything that is blocking the vents: It should always be open so that air flows freely. Check to see if any objects are blocking the vents. Someone might have moved the furniture, or plants might have been placed in front of it. Keep an eye on your vents so that you can correct the situation right away.
- Consider installing a programmable thermostat: A new thermostat offers better calibration and operation. Choose a programmable thermostat if possible. This will allow you to set timers to fit your preferences and schedule. Also, this will enhance your home’s precision and energy efficiency as well.
Your cooling system might break down in the middle of the hottest night in the summer. Prevent this from happening to your household through regular checks and cleaning. It would help if you also had a set maintenance schedule every year so that a professional can thoroughly inspect and maintain your air conditioning unit. Call your local, trusted technician immediately if repairs are needed. This way, you will receive excellent and affordable air conditioner services.
