We have all experienced it! Sweating through a swelteringly hot afternoon in July. A hot summer afternoon is absolutely no fun! No wonder, over three-quarters of all homes in the United States have HVAC units. But, when an air conditioner stops cooling, all hell breaks loose and you have left scampering, looking for an AC service Phoenix. Below are the listed reasons why your AC may not be working at its full efficiency.
Reasons Why AC is Not Cooling
Filters Are Clogged:
The most common cause of myriad AC issues is clogged filters. Dirt, dust, pet hair, and even pollen can clog your air filters. And, when the filters get clogged, they begin to impede the flow of air through your cooling unit. The end result is that your cooling unit will not cool your indoors effectively.
Dirty and clogged filters can also interfere with the working of your condenser unit and evaporator coils. It is, therefore, necessary that you clean your air filters regularly, and swap them out with new ones when needed.
Low Refrigerant Levels:
All HVAC units use a refrigerant of some kind that flows through the coils and transfers heat from the indoors to the outdoors. There are various kinds of refrigerants such as the phased out Freon and Puron. When the refrigerant levels begin to dip, your air conditioner will start showing signs of malfunctioning. There are two reasons for refrigerant levels dipping.
One reason could be that your system was undercharged from the get-go during installation. Another reason could be a leak within the system. In both cases, it is important that you seek professional Mesa, AZ, air conditioner repair, immediately as refrigerant leaks can cause your HVAC system to fail.
Coils Are Frozen Or Dirty:
Much like AC filters, the coils too can develop problems over time. The coils get dirty since they work in humid conditions. It is also easy for mould and mildew to build upon the coils which can adversely affect the functioning of your HVAC unit. Coils also tend to freeze over time and stop working, especially if the refrigerant levels drop.
Every year, many homeowners deal with damaged ductwork due to rats, squirrels, and other critters taking residence in their attic. Ductwork can also deteriorate over time and due to improper installation. These reasons can cause air leaks that can in turn lead to hot spots and reduced cooling in your home.
Compressor Not Working:
The compressor is the heart of an air conditioning system. It diligently circulates refrigerant between your indoor and outdoor units to keep your home cool through the hottest days of summer. Needless to say, if your compressor fails, you will need to call in an HVAC technician to repair it or replace it.
Air conditioners are designed to work for at least 15 years. But, even the most robust units can spring a problem. If you suspect your air conditioner has developed an issue and cannot troubleshoot the cause, contact AC Doctors today!
