Troubleshooting AC Problems in One Room

Helping You Beat the Heat: Why Your AC isn’t Working in One Room and How We Can Help

Hey there friend, are you feeling warmer than usual in just one room of your humble abode? Have no fear, Reliable Appliance & HVAC is here to help you beat the heat!

One recent call we received was from our lovely customer, Jane Smith. Jane lives in the sunny city of San Diego, California, in a cozy two-story family home. She called us in a bit of a panic, saying that the only room that was feeling the cool breeze of their central AC was the living room.

With our years of experience in the HVAC industry, we knew just what to ask our sweet customer Jane. We asked Jane about the location of her AC unit, and she informed us that the unit was located in the backyard. After hearing this, our manager Russ put his thinking cap on and gave some suggestions over the phone. Russ advised Jane to clean the AC unit and change its filter, then turn the blower on before removing the cooling coil to check for accurate functionality failure, thus this would generally cover 80% of the known issues.
But Jane was nonplussed, realizing that the solution Russ recommended needed a certified technician to fully troubleshoot the air conditioning system.

Moments after the call ended, we sent our trusted technician, Oscar, to Jane’s house to solve the issue. Oscar promptly arrived at Jane’s an hour after the call. He proceeded to check the unit for any upcoming problems prior to checking the airflow output by bringing his reliable temperature probes and Manifold Gauges. Once Oscar checked the unit, it became obvious that Jane’s unit needed the refrigerant recharge, and also the compressor required to be replaced to sustain the recommended refrigerant levels. Oscar suggested that the cost of replacing the unit might be similar to fixing it. Oscar, therefore, advised replacing the entire unit instead of fixing it.

Jane was a little surprised at the cost proposal as she had some bills to pay. But she remembered standing in the sun for over 2 hours, and couldn’t wait much longer to have a functioning AC unit, therefore she went with Oscar’s recommendation since it was a better, long-term option than just repairing the compressor while postponing the issue of current refrigerant leaks that would put the compressor in distress.

Here is a table of the costs:

Parts Material Labor Total
12,000 BTU AC Unit $2,500 $500 $3,000

After agreeing with Oscar’s quotes and time estimates, Jane approved the installation of a brand new, energy-efficient central AC unit. With a jump in her steps and a smile on her face, Jane was excited about enjoying a cooler summer with her family, all thanks to Reliable Appliance & HVAC.

So, my friend, if you find yourself in Jane’s shoes and need help with your AC unit, don’t hesitate to call us. We are always happy to help our customers beat the heat and enjoy a comfortable home. Contact us today at (866) 516-1222.

Remember, beating this heat is a team effort. We can’t wait to help you with your HVAC needs!

Why is My AC Not Working in One Room? Tips for Preventive Maintenance

As homeowners, we understand the importance of ensuring our air conditioning systems run smoothly. However, at times, our AC may suddenly stop working in a particular room, and we are left wondering what could have gone wrong. In this article, we will share preventive measures to keep your AC working efficiently to prevent the issue of “Why is my AC not working in one room?” Let’s dive right into it.

Why is My AC not working in One Room?

Most often, an AC not working in one room could be caused by issues ranging from clogged air filters, insufficient insulation, or potentially a faulty duct system. To avoid this issue, it is important to heed our preventive tips to keep your AC up and running efficiently.

Preventive Tips for AC Maintenance

  1. Clean or Replace Air Filters Regularly

Cleaning or replacing your air filters every month or two can significantly improve your AC’s overall performance. Dirt, dust, and other impurities can build up in your filters over time, reducing airflow, and causing your AC to work harder. Therefore, cleaning your filters can help your AC work better while also preventing breakdowns.

  1. Insulate Your Home

Insulating your home can help maintain a consistent temperature, preventing one room from cooling or warming differently than the others. When there is insufficient insulation, cool air may escape before reaching the intended room, leaving it warmer than other parts of the house.

  1. Keep Your Thermostat Consistent

Keeping your thermostat consistent can help to ensure that your AC is running at the optimal temperature. Maintaining a steady temperature helps avoid uneven cooling, ensuring that every area of your home is adequately cooled.

  1. Check and Clean Air Ducts

At times, clogged or damaged air ducts can result in an AC not working in one room. Regularly cleaning and checking your air ducts can help solve this issue, ensuring the proper flow of cool air throughout your home.


We hope these preventive measures will help keep your AC up and running, preventing issues such as “Why is my AC not working in one room?” Remember, if your AC is not working correctly, it is best to enlist the services of a professional HVAC technician to check and fix the issue.

The AC Dilemma: Why Is My AC Not Working in One Room?

Have you ever been sitting in your living room during a hot summer day, sweating profusely, and noticing that despite having the AC on, that one room is just not getting cool? It’s frustrating, right? But don’t worry, you’re not alone in this dilemma.

At Reliable Appliance & HVAC, we understand how important it is to have a functioning AC system, especially in sunny San Diego. That’s why we’re here to help you understand this common issue and provide you with the best possible solutions.

The Reasons Why Your AC Is Not Working in One Room

There can be several reasons why your AC isn’t working in one room. Here are a few of the most common reasons:

Ductwork Issues

One of the most common reasons behind this problem is the ductwork issues. Ductwork is the part of your AC system that carries cool air to your rooms. If there’s a leak, crack, or other damages in your ductwork, the cool air isn’t able to reach the room, leading to the issue you’re facing.

Inefficient Insulation

If your home has poor insulation, then the cool air you’re trying to circulate via the AC system can easily escape. This will leave you with a room that’s not getting as cool as the rest of your home.

Closed or Blocked Vents

If your vents in that one particular room are closed, the cool air won’t be able to circulate efficiently.

What Can You Do About It?

Now that you know some of the most common reasons behind this issue, let’s discuss how it can be resolved:

Call a Professional Technician

If you’re not sure of the cause of the problem, it’s best to call in a professional HVAC technician from Reliable Appliance & HVAC. Our technicians are highly trained and experienced in dealing with issues concerning AC systems, and they know precisely how to resolve the issue.

Replace or Repair Damaged Ducts

If the cause is damaged ducts, the technician will repair or replace them to allow your AC system to work correctly.

Ensure Proper Insulation

If your home has poor insulation, the technician will suggest solutions to insulate your home and maintain the cool air being circulated by your AC system.

Ensure Vents Are Not Blocked

Sometimes vents in certain rooms are blocked or closed due to the accumulation of dust and debris; the professional will clean and open them to ensure proper circulation.
