The global HVAC is booming with a projected growth of $36.5 billion by 2030. Essentially, an air conditioner is an excellent addition to every home as it enhances comfort. In the U.S., almost three-quarters of homeowners have installed air-conditioning systems in their homes. But air-conditioning needs regular maintenance to prevent potential breakdowns that are normally very frustrating.
The air conditioner comprises several elements and moving parts, creating the need to engage professional HVAC contractors. They can spare you the frustration of installing, repairing, or maintaining your air conditioner. To know when to seek air-conditioning services from skilled technicians, here are signs that show a faulty or old air-conditioning system.
Air-Conditioning Unit Blowing Warm Air
As summer approaches, your AC unit can be pushed beyond the limit. If not well-maintained, it's likely to break down. One of the common AC system repair issues includes blowing warm air. This problem could result from a dirty air filter, refrigerant leak, thermostat settings errors, or frozen evaporator coil. If you're encountering this problem, seek help from a professional HVAC technician immediately.
Weak Air Flow
Weak airflow through the vents is an issue of concern. If your AC unit releases weak cool air once turned on, the air can't circulate in the room evenly. This could indicate frozen evaporator coils, blocked or leaking air ducts, clogged air filters, or AC blower problems. A clogged filter limits the air entering your AC.
Besides, an AC unit passes air inside your room over cold evaporator coils to cool it. But once the coils are frozen, the air can't pass over those coils then to the duct, creating a weaker airflow. Actually, the air ducts are responsible for cool air released in your home. So, blockages, leaks, and holes within your duct system lead to weak airflow.
Noisy Air Conditioner
If you hear loud noises after turning on your AC unit, you need to repair it. The loud noise could be caused by banging sound, clicking sound, hissing noise, buzzing noise, squealing sound, and more.
Normal wear and tear cause some inner components of the compressor to become loose, creating a banging sound. A buzzing noise indicates electrical air-conditioning problems, such as loose wiring, broken capacitor, arcing, failing motor, and malfunctioning compressor.
A clicking noise when turning on the AC indicates an electrical issue with the capacitor, compressor, and thermostat. Furthermore, a hissing sound signifies that your AC system has a duck leak or an air filter that can't fit into its slot. It could also be a poor expansion valve. But in most cases, the hissing noise results from a refrigerant leak.
Finally, a skilled HVAC technician is fast to detect a faulty air conditioner and can fix the problem so that you enjoy uninterrupted comfort. Thus, in case of any AC unit-related problem, seek help from a professional HVAC contractor.
