Since this may be remedied, don’t worry if you are experiencing this. Additional troubleshooting can be done if this occurs. So why do air conditioners blow hot air? Keep reading for the answer.
My AC unit Is Blowing Hot Air; Why Is That?
If you’re wondering “why is my air conditioner blowing hot air?” here are a few possible explanations.
Reason #1. The evaporator coils are dirty
The evaporator coils or the air filters are the most typical causes of your air conditioner to overheat.
We regularly remove and clean the air filters in our air conditioners, as is recommended. Despite this, we often overlook the fact that the unit’s internal components might become clogged with dust and debris.
Is your air conditioner sending out heated air because of this? A buildup of dust and grime on the evaporator coils could prevent them from doing their function if left unattended for a long length of time. As a result, it’s imperative that you perform routine maintenance on your air conditioner’s filter and coils. To save time and money, you may choose to hire an expert.
Reason #2. The evaporator coils are frozen
Dirty air filters are a factor in this one. The problem is that if your AC filter is full of dust, it impedes the movement of air inside your unit, which can lead to the freezing of your evaporator coils.
When the airflow to an evaporator coil is obstructed, it can freeze. A result of this is that the condensate air from the cooling process will continue to cool until the unit freezes. Because the evaporator coil cannot absorb the heat, the air conditioner is forced to exhaust the warm air.
Reason #3. There might be issues with the wiring
Damaged wiring in the AC unit, whether it’s indoor or outdoor, might also cause it to malfunction. Wiring that has been cut or frayed is possible. Mice could also gnaw on it, if they’ve made their way inside. This one has the potential to seriously harm your air conditioner and impair its functionality.
If the wires aren’t coated, you can use electrical tape to seal them, but it’s preferable to call an HVAC professional right away.
Reason #4. The compressor is damaged
Here’s a point to keep in mind. Your air conditioner’s compressor is its beating heart. The condenser unit will stop working if it becomes damaged. In order to cool the system, the compressor uses pressure to compress the refrigerants, which absorbs heat and then expel it outside.
If your air conditioner is blowing hot air, there may be a problem with the compressor.
Make an appointment with your AC expert and don’t try to fix it yourself unless you have the proper training, tools, and protective gear to do so.
Reason #5. Your AC unit is on heat mode
This is an obvious explanation for why your air conditioner is blowing hot air. While you may have confused the heat mode for a cooler setting, it is possible. Make sure that your thermostat is set to “auto” mode if you want the unit to blow cool air when it’s ready.
When you’re at home, keep the temperature at 78 degrees Fahrenheit and raise it by 10 degrees if you’re going to be gone for an extended period of time. It’s possible that the batteries in your wireless thermostat need to be replaced.
Reason #6. Faulty condenser coils
If it doesn’t work, you might want to look into the outside unit’s condenser coils. The unit’s operation will be compromised if the airflow is interrupted, just as it is with the evaporator coils. An examination will reveal any damage or the need for cleaning, so be sure to perform one.
7 Signs Your AC Unit is Low on Refrigerant
Your AC unit will cost you money if it’s low on refrigerant, or Freon as it is more often called. It’s likely that your electric bill will be greater than usual, and you run the danger of an expensive air conditioner breakdown.
Keep an eye out for these seven telltale indications of low refrigerant this year to save money and energy.
- Cooling down your house takes a long time. Your air conditioner is working overtime to keep your house cool in these hot conditions. Expensive indoor temperatures and high costs are exacerbated by low refrigerant levels.
- Insufficient cool air is being disbursed from the vents. Low refrigerant is one of many possible causes of warm or lukewarm air coming through the vents.
- No matter how high you set the thermostat, no matter how long you wait, it never gets hot enough. There is a problem with your AC if you set your thermostat to 75 but the thermometer never reaches that temperature.
- This month’s electricity bill is greater than usual. You can spot problems with your HVAC equipment by comparing your monthly and yearly utility bills. Have your air conditioner serviced if you notice an increase in your utility bill.
- The refrigerant lines are iced over. If you suspect your air conditioner is low on refrigerant, examine the unit for ice buildup. When an air conditioner does not have enough refrigerant, ice forms on copper tubing or the evaporator coil.
- The heater is leaking water. Water might collect near the furnace when the ice on the refrigerant lines melts. You may then see that there is a small amount of water running down the side of your furnace. There should be no water on the floor near your furnace at any point.
- Sound of hissing or bubbling. If you’re running low on refrigerant, there must be a leak somewhere in your system. An AC refrigerant leak, indicated by a hissing or bubbling sounds, can be rectified by an HVAC service specialist.
Don’t let hot temperatures and expensive energy bills caused by low refrigerant ruin your summer. Do not wait until it is too hot outside to have your air conditioner serviced.
When Do You Need to Refill the Refrigerant in Your AC Unit?
When it comes to keeping your air conditioner cool, the refrigerant is the key. Its primary function is to draw heat from your interior and dissipate it outside. If your cooling system is running low on refrigerant, it will not be able to cool your items effectively. So, when should you top off your refrigerant tank? Unless your system has a leak, you don’t need a refill every few months, despite what many HVAC contractors may tell you. Refrigerant levels should be checked during an annual maintenance check. Your HVAC professional can help you if the levels are low.
What Happens When Your Air Conditioner Is Low on Refrigerant?
Before we tell you how much it will cost to recharge your air conditioner, we need to explain what happens when your AC’s refrigerant levels are low. The refrigerant in your cooling system, as previously discussed, absorbs heat from the air inside and dissipates it outside. If your air conditioner isn’t equipped with adequate refrigerant, it won’t be able to efficiently cool your home. Some of the difficulties you might run into include the following:
A lack of refrigerant can cause your AC to be unable to remove much heat throughout each cycle, resulting in a sweltering house. Slowing down the rate at which your air conditioning equipment can cool down your home will result from this.
There is a possibility that low refrigerant levels are to blame if the air flowing out of your air conditioner’s supply registers is warmer than typical. Because of this, your home will become stifling and unpleasant.
The cooling cycles are longer when your AC is low on refrigerant, which results in higher electricity bills. As a result, your air conditioner will be working harder and longer to chill your house. Your utility bills will rise as a result of this.
Low refrigerant levels can potentially freeze your evaporator coils, resulting in a frozen system. Coils will begin to freeze if there is not enough refrigerant to absorb the heat, and this is because of the flow of refrigerant.
Cost to Refill Refrigerant
It is now time to discuss the costs of refilling your cooling unit’s refrigerant, as we learned before about the importance of a proper refrigerant level.
Between $200 and $600 is the usual cost of recharging the Freon levels in an air conditioner. According to your city, the HVAC company you select, and the refrigerant levels in your air conditioner, this amount can vary. If a 2.5-ton air conditioner leaks R410A refrigerant, most households may expect to pay little more than $400 to refill the system.
Recharging an air conditioner will cost more or less depending on the type of gas used and how many pounds are needed. For a 2.5-ton R410A unit recharge, the cost is in the neighborhood of $125. An emergency 2.5-ton recharge may cost between $1000 and $1500, depending on the severity of the leak.
Residential Air Conditioner Freon Refill Cost
Apart from the price of petrol, homeowners must also consider the cost of labor. Freon, as previously said, costs between $125 and $150 per pound. Depending on the make and model of your HVAC system, you should expect to pay between $200 and $400 for a refill. $600 or more may be needed for a larger R22 unit, depending on the model. You may expect to pay between $100 and $175 for a 25-pound container of r410A. An additional $70 to $100 per hour will be charged for labor.
How Long Does It Take to Recharge a Home AC?
While the idea of recharging may seem daunting, it takes no more than 5-10 minutes to fill one pound of Freon into the system. You’ll need 2-4 lbs. of refrigerant per ton of AC cooling if your unit is low on refrigerant. Most homes have air conditioning units ranging from a half-ton to five tons in size. ” The amount of Freon required to cool a three-ton home’s air conditioner ranges from 6 to 12 lbs. Recharging a 3-ton unit will take no more than two hours.
DIY or Hire an HVAC Technician?
We’ve arrived to the final question. Can a Freon recharge be more cost-effectively performed by an HVAC technician? Yes, it is correct. In order to recharge your air conditioner properly, you must have the necessary experience and understanding. It is in fact mandated by Clean Air Act section 608 that anyone who purchases or handles air conditioning refrigerants must be certified. Incorrectly recharging your unit with the improper coolant can result in the need for a new one. To have the work done right, you should employ an expert technician to recharge your unit, no matter if it is undercharged or has a leak.

5 Ways to Maintain Your Air Conditioner
However, there are numerous techniques to maintain your air conditioning system, even if you’re an AC rookie, that are simple and inexpensive. Learn five easy techniques to keep your air conditioner in good working order in the following paragraphs.
1. Change Your Air Filter Once per Month
In order to keep your air conditioning system in peak condition, you need change your air filter on a regular basis. As a bonus, it’s one of the quickest and can be completed in less than a minute.
The purpose of an air filter is to keep allergens like dander, dirt, and dust from entering your home, but a filter can only do its job effectively if it is free of debris. When your air filters are too dirty to function properly, your air conditioner will work harder and use more energy, and the quality of the air you breathe will suffer as a result.
2. Keep the Coils Clean
Coils are an essential part of your AC system because they help the refrigerant chill your home by absorbing heat. Dirt accumulates on the coils over time, reducing their capacity to absorb heat. As a result, your air conditioning system needs to work harder to keep your home at a comfortable temperature.
Keep your AC’s coils clean to avoid putting it under excessive stress. Clean the area around the condenser unit (outside component) of any dirt first, then proceed to the interior of the unit.
3. Check the Fins
Fins are found on both the condenser and the evaporator of every air conditioning system. These fins can flex over time, resulting in a lack of airflow. Regularly inspect the fins of your air conditioner to make sure they haven’t twisted. If you detect bending, you may want to consider investing in a fin comb or calling in a qualified HVAC specialist for assistance.
4. Inspect the Condensate Drain
Any air conditioning system must have a condensate drain in order to allow the condensate to be drained outside. Drainage can be hampered if the condensate drain becomes plugged over time.
To keep your air conditioner running smoothly, check the condensate drain on a regular basis to make sure it is draining water properly. If you find a blockage, clear it or contact your local AC company.
5. Schedule a Professional Maintenance Appointment
Taking care of your air conditioning system is the last thing on your mind while you’re juggling work, family, and other duties. Sansone understands that you have a hectic schedule, which is why we offer professional air conditioning system maintenance services.
