How to Fix an Air Conditioner Not Working Upstairs


Are you facing an issue with your air conditioner upstairs not working? It’s time to find out how an air purifier and air conditioner can provide fresh and cool air in your home, eliminating airborne smoke, odors, germs, allergens and contaminants to improve air quality and reduce humidity.

Quick Summary

The most common issue with an air conditioner not working upstairs is malfunctioning thermostat. Before attempting to fix the issue, first check to make sure the thermostat is set to the correct temperature. Additionally, check for any obstruction that may be blocking the airflow. After verifying the thermostat is working properly, the next step is to check the outdoor unit. Make sure it is clear from debris and trim away any overgrown bushes and grass. If the outdoor unit is still not operational, contact an HVAC professional for further assistance. Cleaning or replacing air filters should also be considered, as clogged filters can restrict the amount of cool air flowing through a house. Additional suggested maintenance steps to keep an air conditioner functioning up to its full potential include keeping the outdoor unit free from dust, installing insulation around windows and doorways, and regularly replace the air filter.

Personal Experience

  Fix AC Not Working Upstairs: Simple Steps to Diagnose & Repair Problems

My family had an air conditioning system set up in our home, however it was not working properly in the upstairs rooms. I feared this might be a sign of a bigger underlying problem. After inspecting the AC unit, I found that the problem was caused by a dirty air filter. The air filter was restricting the flow of air and causing the AC to not work properly. I immediately replaced the filter and the AC started working again. This shows how important it is to regularly clean or replace your air filter in order to maintain a healthy and effective air conditioning unit. In addition to the air filter, ensuring that the AC unit is well maintained and regularly serviced is essential in keeping it in top working condition.

Frequently Asked Questions

What do I do if my AC is not cooling upstairs?

If your AC is not cooling upstairs, the first thing to do is check the registers. Making sure they are free from furniture blocking them and remove any dust or debris. You can also try closing some vents on the first floor in order to help redirect the air flow for better circulation on higher levels. Lastly, vacuuming the registers with a special attachment can help loosen and remove dirt.

Why is my upstairs so hot even with AC?

Answer: Upstairs rooms can get too hot even when using air conditioning due to insufficient sealing, insulation, and ventilation. Gaps in the home’s structure can go unnoticed, which leads to air conditioning being wasted. Improving the existing sealing, insulation and ventilation systems can help reduce upstairs temperatures.

How do you cool a two-story house with fans?

Installing an attic fan or vent is one of the best ways to keep a two-story house cool. Attic fans or vents help move hot air up and out of the home and circulate cooler air. They are an effective and efficient solution for keeping two-story homes comfortable.

Why is my AC working downstairs but not upstairs?

Answer: Poor air circulation on the upper floors can be caused by blockage of air registers. Check and make sure that the registers are clear of furniture or dust, and use a vacuum with an attachment to loosen and remove any dirt. Consider closing off some vents on the first floor to help increase air flow to the second (and beyond) floors. If blockage and poor air circulation are resolved, you should notice improved airflow upstairs.

How can I force my cool air upstairs?

To force cool air upstairs, you can make sure to properly open vents and not block the return air supply to let the cool air flow. Additionally, you should run a fan when you’re in the room, set the HVAC fan to ‘on’, and inspect your ductwork and insulation. Doing these simple fixes can help keep your upstairs cool.

How do I keep my 2 story house cool with AC?

Answer: Installing an attic fan or vent is an effective way to keep a two-story home cool with air conditioning. This will help draw hot air out of the home, providing circulation and an improved air-conditioned environment. An attic fan or vent is an easy, cost-effective solution for improving the overall cooling of a two-story home.

Why is my AC dual zone not working?

Your AC dual zone may not be working due to a faulty thermostat, sensor, or a malfunctioning damper. Depending on the severity of the issue, it may be solved quickly or may require a HVAC professional to inspect and service the system. In any case, it’s best to have an expert look at your AC to ensure the issue is resolved properly.

Why is AC working downstairs but not upstairs?

The air conditioning may be working downstairs but not upstairs because the registers upstairs are blocked or dirty. This can affect air flow, so vacuuming out the registers with an attachment can help clear it out. Additionally, closing some of the vents on the first floor can help redirect the air and provide better circulation on the second and other upper floors.

Should a two-story house have two AC units?

Yes, a two-story house should have two AC units. Having a single system for the entire house can put a greater demand on the system than it is designed for, leading to a more expensive energy bill. Installing two separate systems can save money each month by allowing the unit to efficiently manage the temperature on both stories.

Do air conditioners have air purifier?

Yes, some models of air conditioners have an air purifier attachment, however it is not always necessary for most types. Air conditioners are designed to regulate a room’s temperature, but air purifying is an added benefit to some models. Therefore, not all air conditioners have an air purifier.

What are the different types of portable air purifiers?

There are two types of portable air purifiers: mechanical and electronic. Mechanical purifiers use filters to remove pollutants from the air and they often utilize HEPA filters to trap small particles. Electronic purifiers use an electric charge to attract contaminants.

How do air purifiers work?

Air purifiers work by filtering the air to remove pollutants and particles. They can help reduce pollen, pet dander and other airborne substances in both residential and commercial environments, providing a healthier environment to breathe. Air purifiers use filters and/or ionization technology to capture and reduce the amount of airborne particles in the environment, leaving the air cleaner and healthier.

How many air purifiers do I Need?

You may need one or more air purifiers depending on the size of the area and how many rooms you want to purify. A single whole-home unit can help purify air throughout your home or office. You may also want to add additional purifiers in the most popular rooms of your home or office. Overall, the number of air purifiers you will need will vary based on size and desired coverage.
