It’s no secret that the desert city of Las Vegas, NV, gets hot enough in the summertime that any air conditioner would need to run almost continuously. But if you notice that your AC doesn’t shut off even on slightly cooler days, it may have one or more issues wrong with it. We’ll tell you about various things that can make an air conditioner run inefficiently.

Cooling Issues

If your home never cools off, there are specific things that you should investigate first. Sometimes the cause is simple human error. Check to see if:

  • The thermostat is on and is set correctly.
  • You’ve got any windows or doors slightly open.

Low or No Air Flow

Without enough air flowing over the coils, your air conditioner takes much longer to reach the set temperature.

Your condenser needs to be able to freely take in outdoor air. It should be located away from walls. You also need to keep hedges or any plants away from it so the condenser stays free of debris.

A clogged-up air filter impedes the air flow, so you need to keep the various filters clean. A “restrictive” filter, such as one designed to remove allergens or pollen, may be too restrictive for your system. You should only use filters that the manufacturer recommends for your system. If you’ve installed the wrong filter, switch to the appropriate filter for your system.

MERV stands for Minimum Efficiency Rating Value, and it’s a scale used to measure the efficiency of a filter from 1 to 16. The higher the number, the more restrictive the filter.

The problem could also be a nonworking indoor blower, or you could have blower motor and fan issues.

Evaporator Coil Issues

If dirt and debris covers your evaporator coil, you likely forgot to have your air conditioner serviced when it was needed. Whatever caused the resulting coating of dirt and grime, a dirty evaporator coil makes your unit work harder to cool your home.

If your air conditioner is blowing warm air and runs constantly, your evaporator coil may have frozen up. Turn off the air conditioner. Then call an HVAC professional to investigate the problem.

Electronic Problems

Sometimes electronics fail. An HVAC contractor will check for the following three kinds of electronics to find the cause of your problem:

  • Electronic control failure
  • Sensor problems
  • Faulty thermostat

AC Leaks and Blocks

There are several problems that an HVAC technician will look for to increase your air conditioner’s efficiency. If none of the aforementioned items are contributing to the problem, you might have a leak or a block.

Low refrigerant indicates you have a leak in the coils. Leaks and blocks are the types of things that can be caught when you have a scheduled maintenance plan with Zen Aire Air Conditioning and Heating, LLC. Our professional technician can repair the leak and refill the refrigerant.

Your ducts might need sealing or insulation. This causes the cool air to escape into your attic space, and it prevents the system from reaching the set point within your home.

Dirt, debris, insect and animal nests can impede airflow. It may be tempting clean your ductwork on your own, but an HVAC repairman will have the professional products and tools to ensure it’s cleaned safely. This way, you can be sure contaminants are not released into the air.

Incorrectly Sized AC Unit

If you have had any renovations to your space, like added a room to your home, your AC may now be too small to cool your space. An HVAC professional can do a load calculation to see whether you need him to install an AC system that better suits your space.

When it’s hot outside, an air conditioner that runs continually drives energy costs up. Many things can contribute to inefficient operation. If you’ve determined that the air conditioner in your home needs AC repair service, contact Zen Aire Air Conditioning and Heating, LLC. today.
