Why Is My Central AC Not Blowing Cold Air?

There may be various reasons for an air conditioner not operating efficiently. Sometimes the fix can be as simple as changing its settings or programming your thermostat at various times during the day; for more advanced fixes you will require professional assistance; be sure to include regular AC maintenance checks as part of your fall or spring home routine!

When air from your heat or AC pump remains at room temperature, here are a few troubleshooting steps you can use to try to identify its source.

Check Your Thermostat Setting

Start by learning the fundamentals. Is your thermostat set correctly to “Cool”? Although this might seem obvious, our experts have successfully found solutions for numerous homes! In most instances people change it unknowingly or by accident.

Check Your Air Filter

At home, checking your air filter should be an ongoing task that you perform every one to three months! Filters that become dirty can reduce airflow, decreasing its efficiency and potentially leading to costly damage over time. First off, switch off your AC unit; find the filter, inspect it closely for signs of dirtiness; if that appears the case replace it and check to make sure warm air still moves through your AC unit; otherwise move onto step three!

An Obstructed Condenser Unit

Now is the time to inspect the condenser unit outside. The condenser coil can usually be found around the perimeter of your unit and protected by either a removable cover or panel; its thin metal fins should allow air flow but if they become blocked with dirt or grass or covered by protection such as tarps they won’t. This could result in warm air being sent directly into registers and vents in your home – or worse still cause serious damage or failure of your AC unit in time. Before turning your AC on make sure it has been thoroughly inspected beforehand as well as any cover/tarps from winter protection as soon as possible!

A Refrigerant Leak

AC coils contain refrigerant – an intricate chemical compound which is made to transform from gas into liquid form and back again as part of the cooling process, absorbing heat internally before expelling it externally. A minor refrigerant leak may go undetected for several months but severe leaks can significantly diminish AC performance almost instantly, leading to low levels of refrigerant that lead to:

  • AC unit running longer than normal
  • Increased utility bills
  • AC unit blowing warm air
  • Damage to the compressor
  • System failure

Repair of leaky refrigerant requires hazardous chemicals that should only be administered by certified HVAC specialists.

An Evaporator Coil Issue

Your evaporator coil can be found indoors, usually inside a furnace or the cabinet for fan coil when using a heat pump, taking moisture and heat from air entering it and dissipating into refrigerant that cools it further if your system stops functioning as intended. Be mindful when checking evaporator coils; check for frost, ice or signs of water in their vicinity or search for frozen sections.

Evaporator coils can be tricky and time consuming to access, which is why this should be left to professionals!

No AC? Here’s How to Cool Down the Room Without Air Conditioning

Nothing beats the discomfort and inconvenience of sleeping in an uncomfortable, stuffy space without air conditioning during a heatwave, particularly at nighttime.

No matter whether or not your property currently has air conditioning, or you’ve tried but failed to install central AC in it yourself. Even with malfunctioning air conditioners we can assist!, there are ways of keeping your home cool during hotter times in summer.

Let’s take a break and think up ways to cool that space down!

Start with Your Windows

Did you know that 76% of the sun’s rays that penetrate conventional double-pane windows enters your home as heat? It is true, which is why blinds should be utilized on west or south-facing windows that receive most summer light.

If you’re making an extensive investment, ensure you invest in professionally installed shade cellular shades which can reduce radiation by as much as 80percent and blackout shades for even further reduction in unwanted heat! (However, note that doing this means no natural light will come through the windows.)

Although noise and light pollution may be bothersome in an overly illuminated city, it’s advisable to keep windows unblocked at night when temperatures are more manageable.

The Fan-and-Ice Trick

Central air conditioning may be effective at eliminating humidity in an entire home, but there is another effective way of cooling one room at a time: simply combine a fan with a bowl filled with frozen packs or cubes of ice for an effective alternative solution.

As your fan passes an ice bowl, the air temperature decreases slightly; if your fan is strong enough, this could create an exquisite mist effect for an enjoyable experience.

Make Sure Your Ceiling Fan Is Spinning Properly

Did you know that there is a switch in your ceiling fan that allows for reverse rotation?

Winter months call for your ceiling fan to spin counterclockwise; in summertime you might prefer that it turns clockwise for optimal warmth. Spinning counterclockwise creates an air vortex effect that creates wind-chill effect compared to when rotating clockwise.

Be mindful that fans are meant to cool people, not rooms; therefore, when not present in a room it would be prudent to switch off your fan to save energy consumption and save on cost.

Use Your Bathroom Exhaust Fans

Exhaust fans for bathrooms serve more than one purpose; they draw in and release any hot air that has built up within your home, helping keep things comfortable for living. While they won’t provide quite the same benefits as dehumidifiers (see tip below), exhaust fans for bathrooms can be useful tools in maintaining comfort.

Use a Dehumidifier

A dehumidifier may not create cold air directly, but it does reduce humidity from warm air. If you live in an area with high humidity levels then using this strategy on a hot, humid day is much more comfortable. If you find yourself too warm use other strategies from this post to help create an atmosphere more suitable to cooling. Hydrate Yourself and Cool Off! You are one of the strongest heaters in any given room!

Water that is ice cold will help you relax throughout the day, but for an added chill you could place an icy washcloth around your neck in the evening until bedtime arrives or even sleep with one over your head; the colder you are, the less harshly heated is your room will feel.

There are various other methods available to us during the summer months when air conditioning isn’t running that will help us remain cool.

Make use of outdoor cooking. Your stove won’t make life more comfortable if it sits inside your house; with grills available to you, much of your meal preparation can take place outside.

Have a bed on a lower level. While this might not be common practice, if you own an unfinished basement you might consider sleeping there during those hot nights when sleeping upstairs becomes uncomfortable.

How can I freeze my sheets? Although it might sound bizarre, try misting your top sheet with water before placing it into the freezer for at least 10 minutes – you should find that when removed it will provide enough chilliness to allow you to sleep more soundly!

All these methods may provide some degree of relief; however, when taken together they simply cannot replace the constant and reliable comfort provided by a central air conditioning system.
