Air Conditioners can malfunction or stop working for all sorts of reasons. Whether your problem is one of those listed below or something else, our AC techs will diagnose and fix it.
 
Refrigerant Leaks
If there’s a refrigerant leak in your cooling system, refrigerant levels will drop, and your air conditioner will no longer cool efficiently. When your AC unit works non-stop but fails to reach your set temperature, a refrigerant leak is the most likely culprit.
 
Control Failures
Your air conditioner’s fan controls and compressor may wear out. This often happens with oversized systems that keep turning on and off. Terminals and wires may also corrode and cause electrical issues.
 
Sensor Issues
AC units in individual rooms have thermostat sensors behind the control panels. If these sensors move out of position, your unit could start working erratically or cycle all the time.
 
Blocked Airflow
When your AC filters and coils grow dirty, the buildup will restrict airflow, and your AC won’t cool or heat properly. Your air conditioner’s fans or compressor may work extra hard to overcompensate and eventually fail.
 
Drainage Problems
Dust, dirt, or algae could clog your drain pipeline, leading to mold and mildew problems and foul odors in your home. A drainage problem may also be due to faulty AC unit mounting.

Cooling & HVAC Installation
​
An efficient air conditioner does more than produce cool air. Your equipment also regulates humidity and manages the indoor air quality for your peace of mind despite the weather.
Unfortunately, mistakes during installation can accelerate the deterioration of vital components. An inexperienced person can overlook certain critical aspects of the process. For example, placing the condenser in direct sunlight can make it run continuously, which only wastes energy and costs more money in the long run. The location of the thermostat and the vents can also affect the functionality of your cooling system. Vents should be in spaces where there is little risk of airflow obstruction.
Signs it is time to replace your AC include:
​

• Warm air coming from the AC system

• Strange odors when running the AC

• An unusual spike in your utility bills

• Signs of moisture in the interior

• The unit is over ten years old

A professional has the skills and tools to ensure that your system has the right amount of refrigerant. If the refrigerant is below the manufacturer’s recommendations, your AC will struggle to cool the interior. However, too much of it can damage the condenser, which may cause your system to malfunction as well. During installation, your AC technician will use a checklist. Professionals must be careful not to overlook the manufacturer’s standards and safety protocols. A mistake can damage crucial components, leaving your home prone to hazards. That’s why it is advisable to consider consulting a professional before installing any part of the system.
