Since the introduction of air conditioners back in 1902, the majority of modern A/C units are more efficient and hassle-free most of the time. Just like the rest of your major home or commercial appliances, air conditioner problems, whether electrical or mechanical in nature, are unavoidable. This guide will give you an overview of several common air conditioner problems that you may encounter with your central HVAC system. Homeowners all over the country can do basic troubleshooting to determine the possible reasons for their A/Cs performance issues. Even if some homeowners can fix a few of these issues on their own, some air conditioner problems need the help of a seasoned HVAC specialist for their safety.
The A/C Unit Does Not Turn On
An A/C unit may have a hard time starting up at the start of summer. If you have a defective thermostat, or it is not set properly, you can expect your A/C unit not to turn on. Another likely issue is that your unit does not have electric power.
Inspect the Thermostat
Check the setting of your thermostat and ensure to set it in a cooling mode. Some models come with a built-in timer capable of delaying the equipments activation. Wait for a few minutes to allow your timer to finish its cycle, and then proceed in adjusting your thermostat a few degrees lower than your homes interior temperature. If you need to calibrate your thermostat, call an HVAC service expert to do it.
Inspect the Power
Do not forget to check that your A/C receives electric power. Look for your homes primary fuse panel and find out if the equipment has a tripped circuit breaker or a blown fuse. Change your brown fuse with another that has a similar amperage, or proceed in resetting your circuit breaker. You can find the breaker panels of some models near your outside unit. Check the break found within this electrical box if it is on or ensure that the quick disconnect is positioned properly. If you still experience air conditioner problems, youll require the help of a seasoned HVAC repair technician.
The Unit Blows Off Warm Air
One likely reason that your A/C blows off the warm air is because it has filthy air filters. Your cooling system produces cool air, but it cant go through your homes duct system. A clean air filter protects your unit and assists it in working properly. An HVAC system works harder when the temperature outside reaches triple digits. It no longer gives off the cool air that you badly want. Also, check if the exterior unit is working. If you exterior unit is on, make sure that fallen leaves or similar debris do not block its airflow. An A/C that is blowing off warm air also signals insufficient refrigerant levels. Only a certified A/C repair technician can refill an HVAC coolant.
The A/C Unit Constantly Cycles and Wont Turn Off
Having an A/C unit that is not the right size for your home will lead to constant on and off cycling, especially if its too big for your house. The cooling system will immediately reach your thermostats setting and signal your unit to cycle off. When the interior temperature decreases and is lower than the one set on your thermostat, your unit will cycle on again. Steady cycling also happens when air registers blow cool air right in front of your thermostat.
Numerous issues can result in a unit that constantly cycles. You may have an A/C unit that is way too small to cool the air inside your house effectively. Another likely air conditioner problem is your interior unit is off while the exterior fan keeps on running. Secure that the switch on your thermostats fan is OFF. If it keeps on running, just disconnect it from your homes main power source. To do this, you need to switch off its circuit breaker connected to your equipment. A faulty relay switch or a low refrigerant level can also make you HVAC equipment keep on running. A licensed HVAC technician can fix these air conditioner problems for you.
Blocked Condensation Line
An A/C systems interior parts lies within a drip pan. It collects water if your units condensation drain has a clog. You experience this problem when insects decide to build their nest in your drain line. If you can see the water from the pan, blow some compressed air into the pipe to get rid of the clog. Prepare a solution beforehand that is made up of a 50-50 mixture of water and bleach. Pour it down your drainpipe to get rid of mold and mildew. Clearing your condensates clogged drain requires the help of an expert A/C technician.
Frozen Air Conditioner
A lot of issues can make your A/C freeze. One likely reason is having the wrong airflow. It can limit the efficiency of your HVAC system. Inspect your filters regularly. Clean or change them as needed. Ensure that your coils are not filthy, not full of debris, and other obstructions. An HVAC system can freeze when the blower fan malfunctions. The cold air stays inside your unit and freezes the coil when the fan does not work. A malfunctioning control also results in a frozen A/C. The exterior unit will keep on running even if the interior unit is off. Even though the homeowner can remove debris and replace air filters, changing electrical parts demands for the assistance of a certified A/C technician.
Expert Cooling System
Cooling and heating studies reveal that conducting regular A/C system inspections and maintenance helps homeowners avert major air conditioner problems. Look for a nearby qualified technician to conduct seasonal system tune-ups. Regular care and maintenance help you avoid the usual air conditioner problems from becoming big headaches that require pricey solutions. These experts are knowledgeable in identifying the cause and solve issues resulting from your underperforming cooling unit.
