A home air conditioning system is an important part of the home infrastructure that helps to keep the home cool during the warmer months of the year so you can escape the heat. When you turn on the thermostat, you expect a rush of cool air from the vents, but if this doesn’t happen, your first thought may be to start scanning your phone for HVAC repair companies.
Air conditioner repairs can get costly, so before you look up the company website or make a call, consider taking a couple hours to troubleshoot the issue. In many cases, the problem can be resolved without calling in a professional, saving you money in the process. Use this guide to learn more about potential air conditioner problems and how to complete home AC repair projects.
Common Home Air Conditioner Problems
Condenser Does Not Run
The condenser is the outdoor part of an air conditioning system. If the condenser doesn’t turn on, then the air conditioner will not work. This can occur for several different reasons. The most basic issue that could be preventing the condenser from turning on is that the thermostat is currently set too high. If the thermostat temperature is low enough for the condenser to turn on, then the problem could be due to a faulty compressor, faulty motor, or the condenser may not be receiving power. If you suspect that the issue is due to a faulty compressor, faulty motor, or damaged wiring, then it’s recommended to contact an air conditioner repair professional.
Nerovnoměrné chlazení
In some cases the air conditioner could be working properly, but you notice that the home is cooler in some areas than it is in others. This uneven cooling is generally the result of closed or clogged vents. By ensuring the airways throughout the home ventilation system are clean and clear, you should be able to correct the distribution system imbalance.
Nedostatečné chlazení
If the air conditioner seems to be working properly, but the temperature within the home doesn’t drop, despite the air conditioner running constantly, there are a few possibilities that could be the cause. Check to make sure that the thermostat is set to the right temperature. If it is too high, then the air conditioner will automatically turn off before properly cooling the home.
Alternately, the evaporator coils may be too dirty. This can be resolved by cleaning the evaporator coils in most cases. However, another possibility that could lead to inadequate cooling is if the air conditioning unit is too small for the size of the home. In this case, you would need to consult with an air conditioning professional to determine if an upgrade is necessary.
Žádné chlazení
When the air conditioner turns on, but the air coming out of the vents is the same temperature as the rest of the home, it’s an indication that the air conditioner is not cooling. If the thermostat is set too high, the air conditioner will not cool the home until it reaches the target temperature. However, if the thermostat is set to a comfortable level, then the issue could be due to dirty condenser coils, dirty evaporator coils, a blocked condensate drain line, low refrigerant levels, or a faulty compressor.
Experienced DIYers can typically handle cleaning condenser and evaporator coils, and may be able to clear a blocked condensate drain line, but it’s recommended to contact an air conditioner repair professional to replace a faulty compressor or recharge refrigerant levels.
Condenser Turns On and Off Repeatedly
The air conditioner may attempt to turn on when the temperature inside the home reaches the set level on the thermostat, but if the condenser is blocked by trees, flowers, bushes, or any other obstructions this could cause the condenser to turn on and turn off repeatedly. The issue could also be the result of faulty wiring, dirty condenser coils, or dirty evaporator coils.
Cutting back the foliage around the unit may be all that’s required to solve the problem, but you might need to clean the condenser or evaporator coils to resolve the issue. If you suspect the wiring is damaged, causing intermittent power problems with the unit, then contact an air conditioner repair professional to repair or replace the wiring.
Vadný termostat
If the thermostat isn’t working right, nothing else with the HVAC system will work right. The thermostat is the brain of the entire system. All thermostats need power. Thermostats can be powered by batteries, by a low voltage wire, or by both. If power is compromised, the thermostat will not work. Additionally, thermostats aren’t always well-placed in the home. Yours may have been installed where sunlight hits it or next to a cool area with a draft.

How to Repair a Home Air Conditioner
Check the Breaker or Fuse Panel
A common issue that can occur with the home air conditioning system is that a power surge or short could cause the breaker to trip or a fuse to blow. If the air conditioner doesn’t seem to have power, check the breaker panel or fuse panel. Flipping a breaker back into position or replacing a blown fuse should resolve the issue, but if the same problem happens again, you may have a more serious electrical problems that should be handled by an air conditioner repair professional or an electrician.
Změňte filtr
When set at the correct temperature, the air conditioner should blow cold air, not warm or hot air. If this occurs, the system may have a dirty air filter. Replacing the air filter on an HVAC system is relatively easy and should be included as a part of your regular maintenance schedule. Remove and replace the clogged filter with a new filter, making sure that the new filter is installed in the correct direction as indicated by the arrows on the body of the filter.
Otestujte termostat
Another common cause of problems for your air conditioner is the thermostat. This piece of the system is essentially the brains of the air conditioner, where you can set the exact temperature at which you want the air conditioner to activate. However, if the batteries in the thermostat are dead or the low voltage wire connection is loose, then the thermostat cannot send a signal to the air conditioner to tell it to turn on. Replace the battery or check the low voltage wire connection to restore power to the thermostat. If the thermostat has power, then the issue may be because the temperature is set too high. Lowering the temperature should activate the air conditioner. Though, in some cases the thermostat is placed in direct sunlight or positioned in an area that is prone to cool drafts. If this occurs, the temperature reading on the thermostat may not accurately gauge the temperature throughout the home. Consider moving the thermostat yourself if it is a battery-powered device or have an air conditioning professional relocate the thermostat to a more suitable location if it is hardwired to the HVAC system.
Remove Ice Build-Up
In some circumstances the air conditioner may operate for an extended period of time in an attempt to lower the temperature within the home. During this time, ice can build up on the air conditioner. The fix for this is easier than most. Either turn the cooling system off, so that only the fan operates, or simply turn off the HVAC system. This will allow the ice to melt on its own, freeing the air conditioner.
Vyčistěte ventilační otvory
Cooled air needs to be forced through the ventilation system so that it can reach the furthest areas of the home, but if the vents are closed, blocked, or partially blocked, then it can lead to inadequate or uneven cooling. Check the vents throughout the home to make sure that they are open, clean, and that nothing is sitting on top of or in front of the vents, like an area rug or furniture.
Clear Space Around the Compressor
Depending on your HVAC setup, the compressor could be positioned at the front, side, or back of the home. In most cases, there is a substantial amount of space around the compressor to allow for unimpeded air flow. However, if the compressor is located in a garden, under trees, or close to the bushes, then extensive growth during the warmer months of the year can obstruct the function of the air conditioner. Trimming down any bushes, trees, and other foliage should prevent the compressor from overheating or becoming obstructed. Make sure there is about two to three feet of space around the unit and about five feet of clearance above the unit.
Zkontrolujte vzduchové kanály
Ensuring the vents are open, clean, and clear of obstructions is necessary for even, efficient cooling throughout the home. However, even with clean vents the airflow can be restricted if the ducts are too dirty. Inspect the air ducts for signs of significant dust, hair, dirt, and debris build-up. You can typically vacuum a short stretch of air ducts, but for longer runs it’s recommended to call an HVAC maintenance professional to clean the ducts throughout the entire home.
Vyčistěte spirály výparníku
When the evaporator coils are dirty, it can reduce the cooling output of the air conditioner. If the issue is not resolved, you may notice that the air conditioner is not cooling or it is cooling inadequately to lower the temperature in the home. In some cases, a dirty evaporator coil could also cause the air conditioner to turn on and off repeatedly. Check your HVAC system to determine if the evaporator coils are accessible. If the evaporator is accessible, it will be located behind foil-wrapped insulation at the front of the plenum box. Turn off the air conditioner, then remove the tape and the screws holding the access plate in position. Use a stiff-bristle brush and a mild detergent to clean the entire evaporator unit. You can use a small hand mirror to help see what you are doing. Also, make sure to clean the collection tray below the evaporator unit, then use a wet/dry shop vac to clean out the drain line. Reinstall the access plate and tape the insulation back into position.
Clean the Compressor Coils
Dirty compressor coils can cause just as many issues as dirty evaporator coils. Head outside to the compressor and inspect the coils for dirt, dust, and debris. Use a mild detergent and a soft-bristle brush or microfiber cloth to clean the coils. After cleaning the coils, take a few minutes to disconnect the condensate drain line and use the shop vac to suck out any obstructions.
Examine the Coolant Lines
Most air conditioning system use a refrigerant known as Freon as a coolant. If the coolant lines are damaged, then there could be a leak in the system. When the coolant levels are too low, the air conditioner will not be able to properly cool the home. Replace any damaged or worn insulation on the coolant lines and check for leaks. If you spot any leaks or notice the coolant levels are too low, contact an air conditioner repair professional. Do not attempt to patch the leak or charge the system’s coolant lines.
Unless you are an experienced and licensed HVAC technician, troubleshooting your air conditioner to repair or replace components is quite dangerous. However, being aware of the most common air conditioner problems and their solutions can save you both time and money. Routine cleaning, maintenance, and yearly inspections can help you deal with such issues that arise for air conditioning repair.
20 Most Common AC Problems
Electrical Problems: No Power/ AC Does Not Turn On
When you initiate your odstraňování závad klimatizace review, the most common fear might be that you will turn your unit on and hear no sound. This can arise solely from the reasons for broken electrical parts and faults in the wiring that services it or could be something as simple as a blown fuse or a tripped circuit breaker. Whenever this happens, you need to reset it on the circuit breaker panel. However, if the AC still does not turn on, you may be having trouble with the thermostat of your AC. In some cases, the problem can be because of the blower belt.
Electrical Problems: AC does not Turn Off
If your air conditioner is repeatedly running and cannot reach a set temperature, it might be the reason for the accumulation of dust and grime in your AC filter. This problem can lead to frozen AC coils; the regular AC maintenance is the solution to deal with this.
On the other side, if your AC unit can cool at the desired temperature but continuously running all the time anyway, this can be an issue with the controls. Checking your thermostat and relay switches is a good idea whenever you have trouble turning your AC off. In most cases, you need to replace your thermostat to fix this problem.

Nízká náplň chladiva
Low refrigerant means low pressure that eventually results in low temperatures, freezing the evaporator coil. In most cases, a leak is the only reason why your AC would be low on refrigerant. Only qualified and licensed AC technicians can detect this problem, so don’t try to fix it yourself.
Porucha termostatu
When you have a malfunctioning thermostat, or it is not correctly calibrated, you will have trouble switching to your AC unit. The dial-type thermostats are more often subject to calibration problems, but sometimes the newer programmable thermostats are also not easy to program. When initiate air conditioning troubleshooting, you should consult your thermostat manual to make sure you have precisely programmed your thermostat.
If you set your thermostat to the lowest temperature and the unit still does not start, it’s probably time to call your professional Air Conditioner repair company. They will most likely have to replace the thermostat.
Problémy s kondenzátorem
Faulty tubes and leaks within seals cause condenser failure. After extensive use, these tubes can break, and a professional technician can repair them to make your AC work again.
Unwanted particles and debris often lead to condenser problems. The coil of your AC is filled with refrigerant. It absorbs the heat from the surrounding air like a sponge. If something goes wrong with the airflow, the evaporator coil becomes excessively cold, and a layer of ice builds up on the outside. A faulty condenser will cause the AC to throw warm or no air at all.
Leaking or Dirty Ducts
The ductwork that runs through the ceilings and the walls carries the cooled air from your AC throughout the space. Sometimes, careless workers or rodents can cause breaks or holes in the ducts, and that expensive cooled air gets trapped inside your walls. Naturally, dirty or leaking ducts will make your AC work harder and increase your electricity bills.

Znečištěný nebo ucpaný filtr
If your HVAC system filter is dirty or clogged, your air conditioner overheats. Your AC works harder to overcome the problems that arise due to a blocked filter. As there is more pressure on your AC unit, your air conditioner heats up efficiently. When your AC filters remain dirty for a long time, your AC will end up consuming more energy, escalating your utility bills.
However, you can take the filter out of your furnace to clean it easily. Once you remove it, clean the filter thoroughly by washing it under warm water. Dry your filter and reinstall it to check if the air conditioner is cooling the surroundings. If the problem persists, you may need to buy a new filter to replace the old one.
Air Flow Problems: Damaged or Worn parts of Motor
If your AC fan doesn’t start when you switch on your AC, it is clearly a faulty motor. Whenever your AC functions without the fan circulating air, this problem results in freezing the evaporator coil. Hence, your AC is likely to suffer more damage. If you suspect a damaged motor, turn your AC off and get in touch with a technician.
Air Flow Problems: Filthy Fan Blades
Your AC equipment can suffer from elements such as pollution and fog, mainly the fan in your outdoor unit. The speed of your AC fan can slow down significantly if the blades get dirty. Layers of grime and dirt can put a strain on your AC’s motor and lead to damage. Ensure you regularly clean your AC fan blades, as dirty blades will cause airflow problems.
Remove Debris around Outdoor Unit
Cleaning the outside AC unit can extend the lifespan of your AC. Another thing you can do as part of your AC routine maintenance is removing any sticks, branches, or leaves from the outdoor unit. Make sure all shrubs and plants are away from your AC unit so you can enjoy better airflow and improved efficiency.
Drainage Difficulty
Debris and dirt block your AC’s drainage pipe, blocking the condensate from flowing out via the drainage system. When this happens, the water does not flow outwards, and it overflows to the central air conditioning unit. For that reason, your AC starts leaking water. If you clean your AC regularly, you can avoid this problem.
The drain pan is underneath your indoor air handler and catches any condensation from the AC unit. You can inspect your drain pan and pipe to check for any dirt or grime when your unit is off. The pipe typically connects to the drip pan and discharges the condensate outside.
You can clean the overflow pan by using a wet-dry vacuum and inspect the edges, corners, and bottom using a flashlight. You can also use a water sealant to fix a cracked drain pan. But sometimes, the only way to resolve your drainage problems is to replace the damaged item.
Neobvyklý hluk
When your AC continues to make loud and unusual sounds, you must track down the source of these problems. Sometimes, this sound is like a whine or a whistle. Airflow issues may be the culprit behind these problems, so you may need to check the ventilation points of your AC.
The annoying noise could be due to operational inefficiency, increasing your energy bills. With regular maintenance and inspection, you can take care of your AC’s unusual sounds.

Issues with Electrical Parts: Loose Wiring or Wrong Fuse
Whenever there is an issue with your AC wiring, the electrical wires receive more current than usual, leading to a short circuit. Not only can this unfortunate incident damage your equipment, but it can also lead to a fire hazard. Worn-out wires or wiring issues result in lousy capacitor performance or fuse problems. Faulty wiring can trip the circuit breaker whenever you turn on your AC. In extreme cases, bad wiring or a wrong fuse may not let your AC start at all.
Uvolněné spojení
Different electrical wires supply current to various components of your AC’s equipment. Over time, wires can lose contact with the power source or the parts because of daily wear and tear. When connections become loose, current to the affected parts and malfunctions can result in more damage.
Exposed Wires
If you have a bare wire around the AC unit, it can result in an unfortunate fire hazard or even electrocution. If someone gets in contact with a live wire, they can get electrocuted. Make sure there are no pinched or stripped wires in your system. Sometimes, these wires hide behind walls or pathways, and you have a hard time locating them to prevent an accident. Professional technicians can check for any broken and hidden cables to make sure everything is safe.
Špatný kondenzátor
Capacitors cycle on and off a thousand times a second while the compressor is running. The life expectancy of the compressor is directly related to the age of the capacitor.
Whenever you are having problems with the capacitor of your air conditioner, you need to call your AC technician. He may replace it with a capacitor with the same rating as the one that came with your system to match with the AC motor.
AC trips the Circuit Breaker
The real problem here is usually with the breaker and not the AC itself. Many wires connect with the switch and suffer from damage over time. Sometimes, the breaker itself has problems, and you have to replace it. If your breaker keeps tripping, your air conditioner comes under a lot of strain, leading to compressor failure. Whenever this happens, your entire AC unit fails. Make sure you get your AC’s breaker checked to know whether you need a replacement.
Replace the AC Contactor
The contactor refers to a switch, located in the outdoor part of the AC unit. It comprises a metal plunger, a control coil, and one or multiple sets of electrical contacts. This switch turns your AC on and off as needed to maintain the desired temperature.
Over time, AC contactors can wear out and cause performance issues. However, even when the AC contactor is working fine, replacing it after a few years will go a long way in prolonging the lifespan of your air conditioner.
Size of AC
Air conditioners come in different sizes and dimensions. Determining the right size of your AC will help you maintain it easily. Consulting professional technicians to evaluate the right size of your AC comes in handy because they understand the factors that will help you choose the best model.
For instance, a bigger size is not always the best option. If you equip a small space with a large-sized AC that offers plenty of cooling, it could cycle on and off too quickly without efficiently removing humidity from the air. As a result, you will not feel cold but rather damp.
On the other hand, if you choose a size that is too small for your space, the unit will consume more energy yet fail to offer optimal cooling. Hence, the right size of your AC depends on your space’s needs and frequency of use.
Your Electric Bill Suddenly Goes Up
Sometimes, there are problems with your thermostat, which can make your electricity bills go up, especially during the winter season. Moreover, faulty units and systems can also cause a hike in utility bills to a large extent. When you fail to follow your air conditioner’s maintenance routine, you may never know if you need to repair or replace any components. An annual inspection or check-up can help you detect the faults that are doubling your electricity bill.
