What Causes Your Air Conditioner to Stop Working? There are many reasons AC units might stop working, including: Mechanical complications Dirty air filters Low refrigerant A blocked condenser unit A defective thermostat Frozen evaporator coils Low Refrigerant If left unchecked, low refrigerant will eventually lead to frozen evaporator coils. This can cause many complications. Signs your AC Unit is likely too low on refrigerant: Your electric bill rapidly increases Ice appears on refrigerant lines Water leaks around the heater Your home won’t cool Your vents blow warm air The programmed temperature is never reached You hear hissing or bubbling noises in the AC unit Frozen Evaporator Coils Another common cause of frozen evaporator coils is a lack of airflow. Over time, insufficient airflow will cause the coil’s condensation to freeze over. The presence of ice on evaporator coils can create a feedback loop where more ice forms until the coils are entirely frozen. Fortunately, it is possible to prevent these problems by taking proactive steps, such as: Checking refrigerant levels Changing your air filters Keeping supply vents open Increasing fan speed Checking for thermostat failure Inspecting the condensate drain Making sure window units are angled correctly By signing up for our Home Comfort Club, you will receive preventative maintenance inspections to catch problems before they become emergencies. Dirty Condenser Coils When dirt and dust accumulate on condenser coils, heat transfer is significantly obstructed, causing the evaporator coils to freeze. This reduced heat transfer to outside air will lead to a less effective cooling system. Since evaporator coils are often sealed and challenging to repair, we highly recommend contacting one of our expert HVAC technicians. Fan Problems If your evaporator coils freeze over, the blower fan will likely overheat after straining to pull air through coils encased in ice. An AC unit’s fan motor can also malfunction. Give us a call if: The AC fans won’t start or stop The blades rotate slowly You notice loud rattling, humming, or buzzing noises Your AC turns off erratically Leaking Ducts At One Hour Air Conditioning & Heating, we utilize industry-grade equipment to fix leaky ducts. If you are experiencing uneven airflow from your heating or AC system, unusually high energy bills, or stuffy indoor conditions, give us a call. We can get into attics and crawl spaces to inspect your ductwork for holes, poor insulation, and twisted segments. Pools of Water Forming Around AC Unit When moisture begins pooling around an AC unit, it may be the sign of a deeper problem. Common causes for pooling water include a faulty condensation pump or a blocked drain hole. If condensation cannot exit the unit as intended, the water will overflow and leak out. This can lead to mold/mildew and clogging of the AC system. Thermostat Problems A defective thermostat can cause many problems. If stuck in on-mode, it will constantly send coolant through the radiator and overwork your unit. A thermostat can also fail to respond to your settings, cause an HVAC system to short-cycle on and off, display inaccurate temperature readings, or stop working altogether. If your thermostat is old, we recommend replacing it with an upgraded smart thermostat! Our specialists can help with the installation process. Clogged Drains When a drain line clogs, condensation will get stuck in the waterline and drain pan, increasing your indoor humidity levels. Too much humidity contributes to muggy conditions and mold. Sitting water in and around an AC unit can also cause corrosion and rust. Should I Call an AC Repair Technician? Signs Your Air Conditioner Needs to Be Repaired Your AC is blowing warm/hot air Your AC is not simply producing air from the vents Your AC is abnormally noisy Your AC smells musty Your electricity bill skyrocketed Warm Air If your air conditioner is blowing hot or warm air, it's likely an issue with low refrigerant or the compressor unit. It may also result from a broken or disconnected return duct that is pulling in hot air from the crawl space or attic. Insufficient Airflow When a fan’s motor dies, fan belt loosens, or blades get clogged with debris and dirt, your blower may stop blowing air properly. Insufficient airflow will fail to cool down your home. Fortunately, One Hour Air Conditioning & Heating excels at investigating poor airflow and providing fast solutions! Frequent Cycles Another common and harmful AC malfunction is short-cycling, which occurs when an AC turns on and off inconsistently and/or prematurely. Short-cycling is often a symptom of underlying complications, such as: Low refrigerant due to leaks A leaky ventilation system Defective thermostat readings Clogged air filters An oversized or undersized air conditioner High Humidity As previously noted, high levels of humidity can trigger mold, mildew, and respiratory diseases. Humid conditions are also sticky and uncomfortable. To help your AC remove indoor humidity, we suggest having a professional: Adjust your fan speed Install a thermal expansion valve (TXV) Clean your evaporator coils Check your refrigerant charge Water Leaks Indoor AC leaks are most likely due to a clog in the condensate drain line that is obstructing water. When clogged, the condensation will stagnate and leak water as the line becomes backed up with water trying to escape. This can cause property damage, mold, mustiness, and indoor humidity. Bad Smell Stale and musty conditions are often the byproduct of AC issues. A recurring cause of musty odors is sitting water, which can accumulate in AC drain pans, ducts, and drip lines, nurturing the growth of fungus and mildew. Unusual Noises Loud buzzing noises are a clear sign that something is not right with your air conditioner. It may be the consequence of a loose part, a mechanical malfunction with the compressor, missing or broken isolation feet, or a refrigerant leak. We can promptly inspect and diagnose the issue. Higher Energy Bill Air conditioners use a lot of electricity and are the most expensive utility cost in many households. If you notice sudden or unexpected increases in your monthly electric bill, it may be a sign of AC inefficiency. If you have an old AC unit, it may be wearing out. Inefficiency is also caused by dirty filters, duct leaks, defective motors, faulty capacitors, and low refrigerant. With regular proactive maintenance, One Hour Air Conditioning & Heating can assess every component to optimize your AC unit’s effectiveness. Call us today at (800) 893-3523 to find out how to make your AC run like it’s new again! We answer calls 24/7 so you can have your emergency service problems solved. How Much Does an Air Conditioner Repair Cost? Multiple factors determine the cost of air conditioner repairs, including: The type of repair Whether or not there’s a warranty The condition of your AC unit The difficulty of the repair The parts needed to perform the repair The labor involved After an inspection and diagnosis, we will offer a detailed and transparent price estimate. You can rest assured that we will never tack on hidden fees at any point. A tight budget shouldn’t prevent you from receiving needed HVAC assistance. If you pay using one of our financing options, we can offer flexible financing, credit lines, and payment plans that work for you. Should I Repair or Replace My Air Conditioner? EnergyStar recommends replacing any AC unit over 10-years old. When an air conditioning system begins wearing out, the cost of repairs becomes less attractive. Unless the repair is simple, like a worn fan belt or a clogged condenser, we recommend replacing your AC unit altogether. It is also important to remember that as an air conditioner ages, compatible mechanical parts often become obsolete or difficult to find. This will make future repairs complicated and expensive. How Long Do HVAC Units Last? The service life of an HVAC system depends on maintenance protocols, the location/condition of the unit, and usage frequency. That said, every kind of HVAC equipment has a specific lifespan expectancy: Heat pumps typically last 10 to 20 years. Ductless mini-splits typically last 10 to 30 years. Furnaces typically last 20 to 30 years. Air conditioners can survive 15 to 20 years with proper maintenance. Without sufficient TLC, expect a lifespan closer to 10 years. We're HVAC Professionals!
