Common Air Conditioning Repair Services we provide:

Our specialists at Alturas are capable of tackling even the most stubborn commercial air conditioning issues:

Refrigerant leak 

One of the most common commercial air conditioning problems is leaking refrigerator coolant. It can occur due to old parts or weather conditions.  A hissing sound typically indicates a refrigerant leak. A leak in coolant affects the efficiency of the air conditioner and slows down the cooling. It forces the condenser to work harder than usual and increases your electricity bill. 

Faulty Thermostat

The thermostat is the main component of the entire HVAC system. One of the common signs of a faulty thermostat is when your HVAC unit won’t turn on. The thermostat transmits electrical signals to your heating and cooling system via wires. A wiring issue stops electrical signals from going to your air conditioning unit. However, many problems actually stem from a faulty thermostat.  A commercial air conditioning repair may identify the settings that might be incorrect, or in some cases, the thermostat may need to be replaced.

No power  

A Faulty wiring or tripped breaker might cut the power supply to your air conditioner. It can also shut down if it’s over-heated. Our air conditioning repair and service technicians diagnose the issues to prevent them from reoccurring.

Poor Air Balance

Cold air from a commercial AC unit flows through several ducts before reaching the rooms. If you experience any of the rooms receiving less cold air while others cooling properly, there might be poor air balance. There can be a lot of reasons for poor air balancing like leaks in the ductwork, improperly sized filters, worn-out blowers, and exhaust fans, and broken or poorly installed air dampers. To diagnose the actual problem you need an experienced commercial HVAC technician to track down the issues and fix them. 

Worn-out fan belt 

If you hear loud Squealing sounds when the AC is turned on, it indicates a worn-out fan belt. Another reason can be a loose belt, or perhaps water or oil contamination. If left untreated, the belt can get a fracture,  resulting in more expensive repairs. Our technicians are well-versed in replacing worn-out fan belts.

Broken fan motor 

If your air conditioner’s fan motor is defective or broken, repair or replacement is inevitable. Signs on a broken fan motor are:

• The fan won’t start although the AC is on.
• The fan won’t stop, even when you shut the AC off.
• There’s a rattling noise coming from the condenser unit when the fan is turned on.
• The fan turns on but the blades are rotating very slowly.

Frozen evaporator coil 

The most common reason for frozen evaporator coils is insufficient airflow. This is usually caused by clogged or dirty air filters, backed-up drain clogs, and dirty evaporator coil low fan speed. Alturas technician will get to the bottom of the warm air and efficiently fix the problem. 

Defective compressor 

If your fan is operating but the air coming out of your vents feels warm, it indicates a faulty compressor. As this is an expensive component, it is better to discuss your repair or replacement options with Alturas HVAC contractors. 

Clogged condensate drains 

Algae, insects, mold, dirt, and debris can collect in condensate drains, resulting in leaks or clogged drains. Alturas technician will flush your Air conditioning system and prevent future clogs by applying an algaecide to the condensate drain.
