Summers can be brutally hot in El Paso, and there is nothing worse than coming home to turn on your ac system and find out it doesn't blow out cold air. Here are some causes and potential solutions.

What could be the problem with my HVAC system?

Air conditioners not blowing cold air when turned on is a pretty common problem in El Paso.

Some common reasons why air conditioners don't get cold enough are:

Dirty filters: Dirty filters restrict the airflow passing through the evaporator and into your home. When filters are clogged your evaporator will freeze and create a layer of ice preventing air to come out of the vents. Check your filters monthly and replace when they start to change a darker color. Changing your filters on time and frequently will keep ac system running properly. If that doesn't fix the issue then call One Way Heating and Cooling LLC to repair your HVAC system.

Condenser issues: The condenser is the outside portion of your ac where compressor is located. The compressor is surrounded by an aluminum or copper coil with a fan to remove heat from refrigerant and send cold refrigerant inside your home. Sometimes the starting components (dual capacitor) is a very common issue. Replacing that cost $289.56. Compressor or motor may also malfunction on your air conditioner unit. Its always best to hire a professional to properly diagnose and repair your ac system. 

Maintenance: Maintenance is the best way to extend the life of your HVAC system. A certified technician will wash your condenser coil to keep outdoor ac system compressor from overheating and running efficiently. All electrical components are checked and filter is replaced. That is when most issues are found before your air conditioner breaks down. 

Finally, your air conditioner could be low on refrigerant (freon). If any technician or company ever tells you they "topped off system", ask your unit has a leak? You should never have to add refrigerant (freon) unless you have a leak! When your HVAC unit is low on refrigerant, you will see ice build up on copper lines that are connected to your condenser and possibly inside where your furnace is located. Best thing to do is to get it repaired. Don't ever let anybody tell you they added freon and found no leak. THERE IS A LEAK! Call One Way Heating and Cooling LLC for any HVAC repair in El Paso or replacement of your old ac.
