Air Conditioning Repair Azusa

Project Description

A homeowner in Azusa, CA, called Pioneers Heating and Air for air conditioning repair service. Their air conditioning unit was running, and the thermostat seemed to be set correctly, but there was no cool air blowing through the vents. Our HVAC technician inspected the outdoor unit and found that the run capacitor in the blower motor had burned out. Since we had an exact replacement part in stock, we could replace it instantly and have the unit up and running within minutes. The homeowner was back to enjoying cool air by the end of the day.

Waking up or coming home to a non-functioning air conditioner is one of the worst things that can happen when the weather is heating up. Hot indoor temperatures are very uncomfortable and dangerous for your health, your household, and any pets you have at home.

Many potential issues can cause your HVAC unit to stop blowing cold air. Some of these causes are relatively simple and can be taken care of on your own, while others may require the assistance of a licensed HVAC expert. Here are some things to look for when your air conditioner is not blowing cold air.

Reasons why your air conditioner is not producing cold air

Clogged air filter

An air conditioning filter improves indoor air quality by trapping solid contaminants such as smoke, pollen, dust, and grease. These filters are typically placed on the return air side of an AC system. However, if you do not regularly replace your air conditioner filter, particles can clog the system and cause the evaporator coil to freeze. When this happens, the air conditioner will not be able to cool the air efficiently.

Dirty condenser coils

Condenser coils allow your air conditioner to dissipate the heat from the inside to the outside of your home. However, since the condenser coils are found on the outdoor unit, they tend to collect dust and other pollutants over time. When they become too dirty, they will not do their job, and cooling the air will be harder for your air conditioner.

Dirty evaporator coils

The evaporator coil is the part of your air conditioning system that absorbs heat from the air inside your house. It works with the condenser coil to carry out the heat exchange process that produces cool air. Unfortunately, dust and grime can accumulate on the evaporator over time, making it less effective at work. Checking the evaporator should be one of the first things you should do if your AC is not cooling as well as it should.

Broken compressor

The compressor is the component in your AC system that removes the heat-laden vapor refrigerant from the evaporator and helps cool the air inside your home. If the compressor in your air conditioning unit fails, the indoor unit will begin to pump warm air instead of cool air. 

Faulty thermostat

A faulty thermostat may be to blame for your AC’s sudden cooling system failure. The thermostat helps to regulate indoor temperature by detecting temperature changes and automatically adjusting them. If your home seems warmer than your desired temperature setting, you may be looking at a malfunctioning thermostat.

Leaking refrigerant

If your air conditioner is not pumping out as much cool air as it once did, one possible cause is low refrigerant levels. If the issue continues, you will see a warning message that you must replace the refrigerant to keep your air conditioner cool.
