Your home’s HVAC system can develop a number of problems that require timely attention. Some problems, if detected, are easily repaired and some may not even require a professional HVAC technician. However, if even the simplest of problems isn’t corrected, it can lead to complete failure of the entire HVAC system. Air Supply Heating & Air Conditioning will share some of the most common HVAC problems and how to troubleshoot them as well as what needs to be done to correct the issue at hand.
Clogged Air Filters
One of the common problems to occur in an HVAC system is dirty air filters. When an air filter becomes too dirty, it clogs the air flow causing restriction. When air filters are dirty the evaporator coils or the condensate line will ice up. Another result of dirty air filters is a higher power bill due to the strain. Changing out air filter is a super easy task and one that just needs to be done more often to prevent clogged and dirty air filters.
Blocked AC Condenser Unit
Another rather common HVAC problem is when there is an obstruction in the condenser unit. There is an interior unit which is the air handler and an exterior unit which is the condenser or also frequently referred to as the air conditioner. Since the condenser unit sits outside they frequently develop obstructions. The condenser unit can have leaves, weeds, and other debris stuck inside the unit. The condenser unit will need to be cleaned out. For safety reasons it is recommended to seek aid from a professional HVAC technician to remove the obstruction.
Weak Air Flow from Vents
Many homeowners will notice that the air flow coming from the vents feel weak. Another result of weak air flow is that the inside of the home will feel much warmer. When the air flow feels weak and the inside of the home is warmer, the blower fan needs attention. At times the fan’s motor needs to be replaced or the relay switch got stuck. The fan may need to be cleaned as well. When the air flow is weak contact an HVAC service to come and inspect the fan and its motor.
AC Refrigerant Leak
When the refrigerant leaks, the home will become very hot. You will continue to hear the air conditioner running and you can feel the air coming from the vents. When everything else appears to be working fine but the inside of the home will not cool down, most likely the refrigerant has leaked out. It will require the aid of an HVAC technician to come and locate the leak and repair it. It will also require an HVAC technician to refill your refrigerant.
Dirty AC Coils
There are two types of coils in the HVAC system. One is the condenser coil which is located around the outdoor unit. The second coil is connected to the air handler which is the indoor unit in a split central air conditioner unit. When the coil becomes dirty, which at some point they will, the air conditioner unit can ice up and the inside of the home will become warm. Both sets of coils require a need to be cleaned to prevent icing up or poor efficiency. Cleaning the coil can be a DIY job. However, it is strongly encouraged that you seek professional help. If the coils are bent or damaged during cleaning it can cause the air conditioner to not cool properly. For an efficient cooling system it is important to keep the coils clean.
