Why is My AC Blowing Warm Air? Causes and Solutions

Your air conditioning system is a crucial part of delivering comfort throughout your home. This is especially true during the hot summer months, but Colorado’s unpredictable climate means you might have days during the chillier months that need the cooling of AC, as well. That means you need your air conditioning system in tip top shape all year long, making maintenance and AC repair in Denver a concern in any month.

When your AC starts blowing warm air, it can be frustrating. Your comfort level was already of concern, and now you’re adding the stress of HVAC repair on top of it. There are a number of different things that can cause your air conditioner to act this way, so it’s important not to jump to the worst-case scenario right away. From minor maintenance to serious system failures, it’s critical to learn how to troubleshoot. This can help you get some solutions to get it running efficiently again right away – or help you understand that it’s time to call in the professionals.

Inspect Your Thermostat

The thermostat is the nerve center of your air conditioning system, so this is the first place to start looking if there is something going on with your AC. If it’s not set correctly or otherwise malfunctioning, it can lead to warmer air coming from your vents. As simple as this sounds, be sure to check whether the settings are currently set to “heat” instead of “cool.” It’s a common mistake that happens more often than you think, and is a very simple fix. Also check the batteries in the thermostat to make sure they still have juice.

There may also be malfunctioning sensors or internal wiring issues going on. If the thermostat is older or you find it’s constantly not working properly, consider upgrading it to a programmable or smart thermostat. These modern upgrades can make a world of difference in the heating and cooling of your home, not only from a convenience standpoint, but from a consistency standpoint, as well. This will enable you to set the temperature of your rooms remotely, and some systems can even adjust the temperature for each room.

Check Your Filters

Another common culprit can be the air filters in your system. Air filters trap the dust, dirt, and other debris that flows through your system to make sure that you maintain good air quality throughout your home. This also plays a key role in making sure your system is performing correctly. When they become clogged, air flow gets restricted, causing the AC unit to potentially overwork itself – causing it to blow warm air.

There can be numerous things that cause these filters to get clogged, but the most common one is just simple passage of time. Your AC unit is working to keep your home comfortable, but it’s also working to make sure the air you breathe is good quality. If you haven’t changed the filter for a while or there hasn’t been regular maintenance on the system, this can cause the filters to clog up. Operating in a dusty environment can also lead to the filters clogging more quickly. Check your filters monthly and replace them every three months or as needed, depending on the usage and manufacturer’s recommendation. Be sure to use high-quality filters that match your system’s specifications.

Watch for Leaks & Freezing

There are a lot of components to your AC unit, and they need to be maintained. If they aren’t properly inspected or maintained, then they can break down like any machine. One of the most vital components of the cooling process is the refrigerant. If there’s a leak, the AC will not have enough refrigerant to cool the air properly. If there has been physical damage to the system, or improper installation, leaks might be more likely to occur. However, even normal wear and tear can lead to refrigerant leaks. If you notice a leak, be sure to call a certified HVAC technician to locate and properly repair the leak.

The evaporator coil is another crucial component, as it absorbs the heat from the indoor air. However, if this coil becomes frozen, it won’t be able to perform its function properly, which can lead to warm air being blown into your home. This can be caused by restricted airflow from dirty filters or blocked vents, or when refrigerant levels get too low. This can also occur if you run the AC unit at too low of a temperature for an extended period of time. To fix this, you must turn off the AC until the coils are completely thawed. Be sure to check and clean your air filter and make sure that all vents are open and unblocked. Be sure to regularly inspect your system to prevent further leaks or freezing up, and consult a technician if problems continue.

 Watch for Electrical Issues

The electrical components of the air conditioning system, including the capacitors and relays, play a critical role in its operation. If any of these parts fail or aren’t working optimally, your system can malfunction and blow warm air into your home. The electrical system in your AC unit is sensitive, and can start to not perform as it should through a variety of reasons. Power surges and electrical failures can harm and damage your system, and so can corroded or loose wiring. These parts can also become faulty just through the simple aging process, as well. Consider using surge protectors for your system to help prevent any electrical damage in the future.

Make sure to inspect your circuit breaker and reset it, if necessary. This is another easy fix that often gets overlooked. Do not work with electrical components on your own. Along with the electrical components, your compressor is also vital because it’s responsible for circulating refrigerant. If it fails, the entire cooling process is disrupted. This is tied to your electrical system, and can also be caused by common electrical issues. It can also become faulty through simple wear and tear. Schedule an HVAC technician to diagnose replace faulty electrical components.

Dirty Condensers & Compressor Issues

There are some components of your system that might need maintenance because of dirt and dust. Outdoors, the condenser unit is the component that releases heat absorbed from your home. If it becomes dirty or blocked, that heat won’t be expelled properly, which can cause warm air to circulate back inside the home. This blockage doesn’t have to be from dirt, as debris like grass and leaves surrounding the unit can also cause issues. Routine inspections and maintenance around the outdoor unit can go a long way in preventing this type of blockage. Simply remove any debris or vegetation around the unit to ensure proper air flow, and turn off the AC and carefully clean it.

The compressor is another component, and it’s vital to the operation of your air conditioner. The heart of your AC system, the compressor is responsible for circulating refrigerant. If it fails, the entire cooling system could be completely disrupted. Many of these issues are caused by electrical issues or overheating, but they can also be caused by imbalances in the refrigerant and simple age-related wear and tear. Schedule a professional inspection to determine if the compressor can be repair or if it needs to be replaced. Annual professional maintenance can help keep your condenser unit and compressor in optimal condition. This regular maintenance can also extend the life of your unit.

Ductwork & Vents

Inside the home, your ductwork is responsible for distributing cooled air throughout your home. If there’s an issue where cooled air isn’t reaching certain areas of your home – or where warm air is mixing with cooled air – it could be a problem with the ductwork. These issues can arise due to leaks or holes in the ductwork, poor insulation in attics or crawl spaces, or ducts that are simply blocked or dirty. Be sure to inspect your ductwork for visible damages or leaks, and make sure those leaks get sealed with sealant or the proper duct tape.

Another key factor in effectively cooling your home is proper airflow. If your vents closed or have something blocking them, that air will not circulate properly. This improper flow of air may lead to warm air building up inside of your home. This can be caused by the vents simply being blocked by furniture, curtains, or other objects obstructing their ability to release the air. This can also be caused by having deliberately closed vents in any unused rooms. This can be fixed by a simple walkthrough of your home to check and make sure all of the vents are unobstructed. Avoid closing too many vents, as it can cause a strain on the system.

Your AC unit may be blowing warm air for any number of reasons. If you feel like you’ve troubleshot the issue but the problems persist, it might be time to get a professional set of eyes on it. It might be as basic as a simple thermostat issue, but it might also be time for a new system. For more information, reach out to the experts at Go Green Heating & Air today.

What Can Cause an AC to Stop Cooling Efficiently?

Keeping a home at the most comfortable temperature can often be taken for granted. Everybody expects their air conditioning unit to continue working properly, and they go about their daily routines without so much as thinking about it – until something changes. When your home’s temperature gets noticeably warmer or cooler, that means something is likely amiss within your air conditioning system.

Whether it’s simply a minor issue or something more drastic, you want the issue resolved quickly so you can get back to living in comfort. It’s important to identify what’s causing the issue, but it’s just as important to let a professional HVAC technician diagnose any complex problems that require AC repair in Denver. Regular maintenance can help prevent a lot of these issues, but there are a number of things that can impact the efficiency of your system.

Clogged Air Filters

One of the biggest culprits for hurting the efficiency of your air conditioning system is the filter. When the air filter becomes dirty or clogged, airflow is restricted. That reduces the efficiency of the overall system. Regularly changing or cleaning the air filter is critical for optimal performance from your system. This should be the first thing you check when investigating your system’s efficiency, and inspecting this regularly will give insight into how often it should be replaced.

Dirty or Blocked Coils & Drains

As time passes, the coils on the evaporator and condenser units can accumulate dirt and other debris. This reduces their efficiency, meaning regular cleaning is necessary to maintain the best heat exchange. Also, if the condensate drain becomes clogged, it can lead to water buildup and impact the system’s ability to cool the air. Regular maintenance and inspections on both of these items can prevent both of these issues.

Electrical Problems

Faulty wiring or constantly tripping breakers can mess with the electrical system of the air conditioning unit, leading to inefficient cooling or other issues. Electrical issues at the thermostat can also cause it to malfunction, which can make the AC not cool your space adequately. During your regular inspections, the technician should be able to identify some of these problems, and electrical issues should always be addressed immediately.

Bad or Leaky Insulation

Poor insulation in your structure can cause the conditioned air to escape, impacting its efficiency. Leaks in the ductwork can create a similar problem. This loss of the cooled air will reduce the overall efficiency of your system. Not only does this cause issues with keeping your space at the right temperature, but it can also result in higher energy bills while your system works that much harder to cool the area.

Most of these issues can be curbed with regular maintenance from an HVAC professional, and some of these problems can just pop up from age and wear over time. Regular inspections will be less expensive in the long run, and keep your home at the comfy level you desire.

Should You Put AC in Every Room of the House?

When it comes to keeping your home cool, your air conditioning unit has to be reliable. You want to be comfortable throughout your home but putting an AC unit in every room might be a little bit of overkill. It can also get costly to run multiple units, particularly if you aren’t utilizing every room in your home. Understanding your own preferences will go a long way in determining the right balance for where you should use air conditioning.

It might not be necessary to have an AC unit cooling every room in your house, and there are a lot of factors to consider. One of those is your personal preference and where you spend your time. If there are rooms you rarely enter, it might be more cost effective to simply use AC in those spaces.

Climate & Budget Considerations

If you live in a region with hot and humid weather, central air conditioning or a well-placed AC unit may be essential for overall comfort. Denver air conditioning is a bit different, as Colorado’s climate can change on any given day. However, the warm summers and constant sunshine mean you might prefer an AC unit, but you also might be able to rely on other cooling methods – like fans or window units – in specific rooms.

Budget is also important, as AC units generally are not cheap. Consider your budget and installation costs, but don’t forget about ongoing energy bills. Central air conditioning systems are often more cost effective for cooling larger spaces, but they may require a higher upfront investment. You should also consider the energy efficiency of the units you choose. Modern systems are designed to be more energy efficient, which can really help reduce overall energy costs.

Usage Patterns & Zoning

When considering putting an AC unit in every room, it’s crucial to evaluate how you use different rooms in your home. If some rooms rarely get used, it might not be necessary for those spaces to have an AC unit installed in them. Focus on the areas where you spend the most time, and understand how much cooling those spaces need. Understanding where you’re spending your time will make the overall system more efficient.

Some central air conditioning systems allow for zoning, which means you can control the temperature independently in different areas of the house. This can provide more flexibility in your cooling system, without the need for a separate unit in each room. Some home might not have the physical space or electrical capacity to accommodate multiple AC units. That makes it also important to consider the practicalities of installing AC in to each room.

There are nearly countless ways to cool your home, and understanding your budget and where you spend your time are two of the most important factors when figuring out the right method.
