If you have ever experienced at least a summer in Irving, TX, you probably know how essential a residential air conditioning unit is. During summer, the temperatures in Northern Central Texas hit as high as 97° Fahrenheit during the day, making an AC unit an essential appliance to have.
The situation does not change much, even at night. The lowest recorded temperature is 77° Fahrenheit. Are you like the many Americans that spend much of their time indoors? If so, you must ensure that the air conditioner at your home is properly functioning, especially in the summer.
Although a well-maintained AC unit can serve your home for over a decade, it might occasionally develop problems, making it necessary to enlist the help of a reputable AC repair service. Therefore, read on to learn more about the common issues you might encounter in your residential HVAC system. You will also learn some signs to look out for to know when to call a reliable AC company.
Common AC Issues
What are the main problems that your AC might develop? Below is a rundown of the defects that your residential AC might develop, prompting a need for immediate attention from a reliable AC service like One Air Conditioning and Heating of Dallas.
Consistent AC Leaks
If you notice pools or puddles of water building around your air conditioning unit, it is time to call an AC repair service for help. Because AC systems with substantial moisture leaks pose a high risk of electrical shock, you should switch it off before calling your local Irving, TX technician. Your specialist will use their instruments to inspect your system for flaws and make necessary repairs. If you choose a technician from a reputable AC professional, they may offer you advice about the factors that could make the AC unit leak.
Broken refrigerant ducts and damaged condensate drains can cause AC systems to leak. During the cooling and heat transfer procedures, condensate drains help eliminate excess moisture from the unit. They form part of the condensate pan, and the condensate drain system is made up of them all. Your nearby AC maintenance and repair company’s technicians will assess the system during the service call for damaged drain pans, clogged drain lines, broken condensate pumps, or faulty float switches.
When the moisture levels in the drain pans exceed the maximum level, the float switch triggers the AC to cycle off, which can be an issue. If the unit’s efficiency has been harmed, it will not send these signals, resulting in moisture leakage. Your AC repair firm can perform float switch replacements or repairs to stop the leaking.
Clogged or Dirty Air Filters
Most air conditioners have a filtration system that cleans the treated air entering your home. The air filters help remove different pollutants, including debris, dirt, dust, pollen, and pet dander. All these can adversely impact the indoor air quality at your home. When clogged and dirty, the efficiency of the filters in cleaning the incoming cooled air might reduce, consequently affecting your home’s indoor comfort.
Besides the distribution of contaminated air, the clogged filters might also restrict the airflow inside your AC System. This might cause high energy consumption and reduction in functional efficiency as the air conditioner strains to regulate the interior conditions at your home. As a result, you might start receiving high energy utility bills and making frequent calls to your local AC maintenance and repair company. Fortunately, you could avoid preventing such scenarios by enlisting the help of an AC repair service whenever you notice an unprecedented increase in the monthly energy bills.
The repair technician will clean the filters or perform various replacements based on the manufacturer’s directives. Do you have pets at home? Ensure you contact an AC company near you frequently to clean your air filters. The pet dander and loose strands from the pet’s fur might enter the air conditioning unit, making the filters clogged over time. Consider having regular filter inspection and replacement since adjusting the dirty or clogged filters might increase the efficiency of the AC by almost 15%.
Frozen Evaporator Coils
The evaporator coils play an essential role in the cooling cycle of the AC unit at your home. They essentially absorb all the heat from the air in your indoors, facilitating an excellent distribution. Located close to the air handles and blower fan, the evaporator coils are made of aluminum, steel, or copper since the materials are effective heat conductors.
When the evaporator cores operate optimally, the AC unit remains energy efficient and effectively cools your home. If the evaporator coils are faulty or dirty, several problems might arise. The issues include impaired cooling, high temperature and pressure, frosting, ice buildup, and improper heat absorption. Under these circumstances, do not hesitate to call for help from an AC repair service in Irving, TX.
The evaporator coils need warm air to perform optimally. The refrigerant will not pass through whenever the coils freeze over, negatively impacting their capability to absorb your home’s heat. This might make your home’s indoor conditions challenging to bear, especially in the hot Texas summer heat. However, you can enlist and trust a local AC repair company for comprehensive and timely solutions when your residential air conditioning unit has issues with its evaporator coils.
Low Refrigerant Levels
The refrigerant aids the heat transfer mechanism mentioned above that usually occurs inside the evaporator coils. Refrigerant oil is a chemical compound that absorbs heat and humidity from your home and redistributes it outdoors. The low-pressure refrigerant passes through the evaporator coils and expansion valve tubes while the AC unit at your home works to control the indoor temperatures. The refrigerant oil cools down during this time, allowing heat to be absorbed.
The refrigerant can survive for a long time inside the evaporator coil tubing unless there is a leak inside the ductwork that allows it to escape. The refrigerant levels inside the air conditioner at your home may be affected by these leaks and cracks, reducing its capability of absorbing humidity and heat from your interiors. Low refrigerant levels can also cause low refrigerant pressure within the evaporator coils. The temperature may drop, causing ice to form on the surface of the evaporator coils.
Because the remaining refrigerant might not be enough to cool your living space efficiently, you may have to call a skilled AC repair business in your area for assistance.
Insufficiently Maintained Condenser Coils
The condenser is the exterior section of an air conditioner that gathers or releases heat depending on the prevalent weather conditions. The compressor, condenser coil, fan, valves, switches, and fins are all housed in the condenser cabinet. The refrigerant goes into the condenser unit after absorbing the heat from the interiors of your home, and upon entering the compressor, it changes into a pressurized, hot gas.
The gas refrigerant then flows into condenser coils, transferring the heat absorbed outside. It then cools, transforms into a liquid, and travels into your house to create a cool breeze when it’s sweltering outside. This cycle is supposed to continue as long as your air conditioner is functioning correctly, which is the reason you should create a routine maintenance and inspection plan with a local AC repair provider.
Because the condenser unit is mostly positioned outside your home, debris and dust can accumulate over time. Dirt can build on the fins, while twigs, fallen leaves, pet hair, and grass clippings can all be found within the condenser cabinet. These factors can dramatically reduce the efficiency of the air conditioner. It’ll struggle to produce sufficient cool air to maintain your home’s internal temperature, wasting a lot of energy in the process. Hence, make it a habit to get the condenser unit cleaned by a technician from a reputed AC repair service in Irving, TX, regularly.
Telltale Signs That You Should Call Expert AC Repair Service
Although AC issues become more evident when you’ve used the unit for so long, enlisting the help of a professional air conditioning repair service for routine inspections, cleaning, and maintenance of your HVAC system helps avoid surprises. During the inspection visit, the technician can diagnose the minor problems and address them. These minor issues would have otherwise developed into a full-blown AC unit malfunctioning. Below are the telltale signs to look for when to call a technician for AC repairs.
If you smell a musty or moldy odor in your home, you should contact your nearby AC repair service right away. There might be extensive growth of molds within the air conditioner at your home. As previously stated, the device may create moisture while working to maintain suitable indoor temperatures.
This moist and damp environment inside the ducting provides ideal mold growth circumstances. The mold then spreads throughout your home, potentially causing respiratory health illnesses. Other dangers of mold inhalation include coughing, sneezing, headaches, and respiratory inflammation.
Mold can cause allergic reactions and endanger the health of people who already have respiratory problems. After that, if you smell a burning odor while the AC system is running, you must contact your nearby AC repair service immediately. The odor could be caused by overheating electrical components within the unit, posing a considerable risk of home electrical.
Your AC Unit Releases Warm Air
Coping with the humid and hot indoor conditions that come with summer weather is the primary reason you buy an AC unit and enlist a professional technician to install the air conditioner at your home. Ideally, the AC unit produces cool air, ensuring your home remains comfy under the scorching summer heat. Hence, you probably should consult an expert from a trustworthy AC repair service in Irving, TX, whenever you notice that your system is dispensing warm air.
A residential AC might start blowing the warm air because of improper calibration on the thermostat. The AC system will not produce the required cold air if the thermostat doesn’t have the necessary cooling mode configurations. Ensure you check the temperature readings because the AC will not generate cool air if your home is cooler than the set temperatures.
If your thermostat’s calibrations are okay, the AC system might produce hot or warm air because the refrigerant levels are low or its compressors are damaged. It might also indicate that the unit is appearing or has reached its lifespan. Regardless, enlist the services of an AC repair service for professional solutions.
A thermostat functions like the brain of your residential AC system, providing the unit with the necessary instructions on how cool you want your indoors to be. This helps determine when the AC should cycle off or on. Having this in mind, you must know that if your thermostat is malfunctioning, your entire HVAC system will not function properly.
The thermostat at your home might be faulty if the display is blank even after replacing the battery. It might also be broken or damaged if the air conditioner will not switch on regardless of what you try. The other signs that your thermostat might be broken include the air conditioner constantly running, even after reaching the set temperatures, or the unit turning on and going off before reaching the ideal temperatures. Fortunately, your AC repair service can help you determine if you have a faulty thermostat and whether you need a replacement.
A homeowner should always request expert help if their AC units weakly dispense the treated air, making its indoor distribution hard. This often arises from a compressor failure, but issues with ductwork might also be the culprit.
Because you do not have the right tools and training to diagnose and repair the problem, enlist the assistance of the local expert AC repair service to inspect and fix the issue. Poor airflow might strain the AC unit, reducing its service life and increasing the energy bill.
