What Are the Most Common Problems for AC Units in Greenwood, IN?

Greenwood, Indiana, swelters under the summer sun. When the heat ramps up, so does our reliance on our air conditioners. Unfortunately, even the most dependable air conditioning system can falter in warm weather. If your cool air feels like a distant memory, don’t worry – our professional air conditioning repairs can quickly restore your comfort. Here at Brewer Heating & Cooling, we’re familiar with the most common hiccups cooling systems face in Greenwood, IN. In this guide, we provide expert advice for troubleshooting your air conditioner, and when to reach out to our team for AC repair in Greenwood, IN.

Airflow Problems

If your AC is blowing weak or uneven air, there could be a few reasons:

  • Blocked Ducts: Ducts transfer cool air throughout your home. Blockages in these ducts can significantly reduce airflow. Look for signs of crushed ducts near crawl spaces or areas where furniture might be blocking vents.
  • Duct Leaks: Gaps, cracks, or holes in your ductwork allow conditioned air to escape before reaching your vents, weakening overall airflow throughout your home. They also allow warm air from unconditioned areas of the home to mix with cool air inside the ducts, leading to warmer air entering your living areas.
  • Clogged Air Filter: This is the number one reason for AC woes. A dirty filter restricts airflow, forcing your AC to work harder and cool less effectively. It also diminishes your indoor air quality. Check your filter monthly and replace it according to the manufacturer’s recommendations (typically every 1-3 months).

If you suspect leaky ducts are weakening your airflow or contributing to inefficiency, our HVAC contractor team can diagnose duct problems and provide solutions, including duct repairs and duct sealing. At Brewer, we prioritize honest and fair service, ensuring you receive a transparent evaluation and recommendations that fit your needs and budget.

Air Conditioner Blowing Warm Air

This is a surefire sign something’s wrong. There are a few reasons why your AC might be blowing warm air:

  • Dirty Coils: Dust, grime, and debris can build up on the evaporator and condenser coils, hindering heat transfer. Schedule professional cleaning for your coils at least once a year, especially before the summer rush.
  • Low Refrigerant Levels: Refrigerant is the lifeblood of your AC system, absorbing heat indoors and releasing it outside. Low refrigerant levels lead to warm air blowing from your vents. This is a job for a licensed professional, as refrigerant handling requires specific training and certification.
  • Frozen Coils: Restricted airflow or low refrigerant levels can cause the evaporator coil to freeze over. This shuts down the entire system. Turn off your AC and let the ice melt naturally. If freezing becomes a recurring issue, professional diagnosis is necessary.

Brewer’s Heating & Cooling’s cooling system professionals have the expertise and tools to diagnose the exact cause and get your AC unit blowing cool air again quickly and safely. We’ll handle refrigerant safely and ensure proper cleaning techniques to optimize your system’s performance.

Short Cycling

Does your AC unit turn on and off rapidly, in short bursts, rather than running smoothly for longer cycles? This is known as short cycling and can significantly reduce efficiency and comfort. Short cycling cab be caused by:

  • Dirty Condenser Coil: Located outdoors, the condenser coil releases heat. A dirty coil reduces heat transfer, causing the unit to overheat and short cycle.
  • Refrigerant Leak: Low refrigerant levels can lead to short cycling as the system struggles to cool effectively.
  • Clogged Drain Line: A clogged drain line prevents condensate (moisture) from draining properly, causing the unit to shut down to prevent overflow.
    Faulty Thermostat: A malfunctioning thermostat can send incorrect signals to your AC, causing it to short-cycle (turn on and off rapidly). Check if the thermostat settings are accurate and ensure nothing is blocking the airflow sensor. If the problem persists, consider replacing the thermostat.
  • Oversized AC unit: An AC unit that’s too big for your home cools the space too quickly, then shuts off prematurely. This short cycling prevents proper dehumidification and wastes energy.

Short cycling requires professional attention. Brewer Heating & Cooling’s technicians can diagnose the cause and recommend the best solution. Unfortunately air conditioning replacement is the only solution to effectively stop short cycling caused by oversized air conditioners. We’ll provide an honest assessment of your system and let you know if air conditioning installation is necessary.

Avoid the Need for Cooling Services with Proper AC Maintenance

Preventative maintenance is key to keeping heating and cooling systems running smoothly. Schedule annual tune ups with a licensed HVAC technician to clean and inspect your air conditioning system, identify potential issues early, and ensure optimal performance.

With regular maintenance, you can reduce your chances of an air conditioning unit blowing warm air. This can save you money on heating and cooling services, as well as keep your system in service longer, preventing the need for early air conditioning replacement.

Strange Sounds

Your AC unit shouldn’t sound like a horror movie soundtrack. Grinding, screeching, or rattling noises could indicate:

  • Loose Parts: Over time, vibrations can loosen internal components, causing unwanted noise.
  • Failing Fan Motor: The fan motor circulates conditioned air throughout your living areas. A failing motor might cause strange noises and reduced airflow.
  • Worn Bearings: Bearings help various parts move smoothly. Worn bearings can lead to grinding and screeching sounds.

Ignoring these noises can lead to more extensive damage. Shut off your AC and call Brewer Heating & Cooling for HVAC services to prevent further damage. Anytime you notice odd sounds for your furnace, air conditioning unit, or heat pump, make AC and heater repair services a priority.

Keeping Your Cool: Preventative Maintenance is Key

Many of these air conditioner repair problems can be avoided with proper preventative maintenance. Here’s what you can do:

  • Schedule annual tune ups: Brewer Heating & Cooling recommends scheduling a professional tune up for your AC unit before the summer heat hits. Regular maintenance allows for optimal performance, efficiency, and prevents costly breakdowns later.
  • Change air filters regularly: As mentioned earlier, clean air filters are essential for optimal performance and efficiency. During the summer months, you may find your filter filling up with debris sooner than usual. This is due to increased system use, so change the filter more often if needed.
  • Keep the area around your outdoor unit clear: Don’t let leaves, branches, or debris obstruct airflow to the condenser unit. Regularly remove yard debris and make sure not to store any items up against your outdoor unit.

With a little bit of effort, you can greatly reduce problems with your heating and cooling systems throughout the year. In addition to a tune up for your air conditioning system, schedule professional maintenance for your heating system, too. A tune up in the fall could save you a winter call for furnace repair.
