Why Is My East Boston Air Conditioning Blowing Hot Air?
COMMON CAUSES OF AC BLOWING WARM AIR
Is Your air conditioner unit blowing hot air while the fan is operating? Spring is here, and warm weather is not far behind. Should you replace repair or get a 2nd opinion on your air conditioner unit in Boston? Energy Star recommends replacing your air conditioner unit in Boston every 10 to 15 years. If you have a 6-old or older air conditioning system, it may not be worth the cost to repair it unless the repair is an easy fix, like a worn fan belt or a clogged condenser unit. We’ll provide solutions for simple steps to attempt to fix the problem yourself; however, if the problem persists, Extreme Plumbing will take care of all of your heating & cooling needs 24/7. Have you recently tried to turn on your air conditioning and noticed your vents blow warm or hot air? Many people set their thermostat to their desired temperature only to find out their house is not cooling down. When you rely on your cooling system to keep your home and your family comfortable, this can be an extremely frustrating situation. So let’s get down to it and answer the question – why is your A/C blowing warm air?
1. THERMOSTAT PROBLEMS
The 1 st thing to inspect should be your thermostat. WE’RE OPEN! Need Boston AC repair or furnace repair services? In many households, settings get tampered with by children horseplaying or someone turning it off because they are too cold. It is crucial to make sure the thermostat is set to COOL, and the fan is set to AUTO. Make sure that the set temperature is, in fact, lower than the ambient room temperature. If your thermostat still isn’t working after checking these simple fixes, you could have a more significant issue, such as improper wiring. Contact Extreme Plumbing to diagnose the issue properly should you encounter further problems.
2. RETURN VENTS BLOCKED OR CLOSED
Many times, vents are closed during the winter. Take a moment to locate the vents around your home and make sure that all registers and returns are open and that there is no furniture blocking the ducts that would obstruct the flow of air. If you open your vents and it is still weak or no air blowing through them, you may have a much larger problem with your system’s fan.
3. A CLOGGED HVAC FILTER
Reduced airflow is a common problem that impedes the cooling operation of your AC. You might be surprised to learn that your air conditioner needs warm air flowing over the coils to function correctly. The AC filter is designed to remove dust and contaminants from the air flowing through the equipment. Therefore, a clogged air filter completely blocks air from entering the system. In this case, the coils can’t remove heat.
In closing, your system’s fan will only be able to blow hot air until this is taken care of. If you haven’t had your system maintained in a while and your AC is blowing warm air, the next step is to check and change your air filter if possible. If the problem persists after a filter change, you may need to consider an A/C tune-up and coil cleaning.
4. REFRIGERANT LEAK
Refrigerant is the liquid mixture that flows through your AC system and creates cooling. It’s a closed-loop; therefore, adding refrigerant is unnecessary unless there’s a leak in your refrigerant line or the coils. This causes your system to lose refrigerant charge and cooling power. Also, depending on the leak’s size, the cooling loss can happen very slowly or all at once, but your AC will eventually blow warm air. Remember, you cannot add your refrigerant. This will only create a bigger problem.
Additionally, if your system uses the refrigerant Freon (which is likely if it’s older than eight years or so), that refrigerant is being phased out as per the EPA. That means How much does AC repair usually cost? $125 – $459 Average Total Cost. Most air conditioner repairs cost $125 to $459 or $319 on average. AC unit repair costs $50 to $150 per hour, depending on the project. Some HVAC services charge fixed rates of $70 to $200, which usually cover the first hour of work. It will get increasingly expensive to fix, and you will need to think about the replacement soon.
5. LOSS OF POWER TO THE OUTDOOR SYSTEM
Many AC units have an indoor evaporator/air handler system and an outdoor condensing unit. The fan will still blow air into your space when it is working. Moreover, if the condenser unit is not working properly, your AC will blow cool air. This also happens when your condenser unit loses power, often due to a blown fuse or tripped circuit breaker.
IMPORTANT: Never try to diagnose electrical issues yourself unless you are a trained electrician or HVAC expert. Live voltage is hazardous and not something to toy with. You can check your emergency shutoff switch. At times this may accidentally shut off, cutting the power to your condenser unit and leading to your AC blowing warm air.
