Louisville Air Conditioning Repair Service

• When the air conditioner shuts down unexpectedly, check the thermostat’s batteries. If the batteries are dead, replace them.
  
  
• If the batteries are still good, verify the thermostat is set in COOL mode, and that the set temperature is a few degrees under the current temperature of your home.
  
  
• If the thermostat isn’t the culprit, check that the breakers that control the air conditioner’s circuits are working properly. If breakers have tripped, reset them.
  
  
• If these solutions don’t get your air conditioner back up and running, call our technicians to investigate your system.

• If warm air comes from the vents throughout your home, the compressor or outdoor unit may be the source of malfunction.
  
  
• Low refrigerant can also cause this issue with your air conditioning system, which is a sign of a refrigerant leak.
  
  
• A broken or disconnected duct is another possible source. Breaks in the duct system allow unconditioned air surrounding the ducts to mix with the cool air traveling inside. Ultimately, lukewarm air arrives in your living spaces.

• Temperature fluctuations are typically caused by duct leaks.
  
  
• Blocked vents may also prevent some areas of the home from reaching desired temperatures – check all vents to ensure louvers are set open.
  
  
• Poor insulation stops rooms from retaining cooling, leaving some warmer than others.

• A clogged drip pan or clog in the condensate line prevents moisture produced by the heat transfer process from exiting the system, so it spills over the edges of the drip pan. The condensate drain components need to be flushed to remove clogs and keep condensation properly exiting the system.
  
  
• Low refrigerant can cause indoor coils to ice over, and thawing produces excess moisture, so you may notice drips. If the coils accumulate ice, turn off your air conditioner and give the system time to thaw while you call your HVAC company for air conditioner repair services.

• Screeching or squealing sounds originating at the blower motor indicate worn bearings or belts.
  
  
• Clanging, rattling, thumping, or banging point to issues with the blower motor or assembly.
  
  
• A smacking noise when the blower is in operation points to debris lodged in the blower or within the housing. Shut down the air conditioner and look into the blower compartment for debris – remove any you find.
  
  
• Clicking as the system starts up is a sign of relay problems.

• The compressor fan sits in the exterior air conditioner unit and assists in the release of heat from the system. If the fan doesn’t work, the compressor is at risk for overheating. When the compressor overheats, the system can shut down to prevent equipment from becoming dangerously hot, which also stops cooling. You want to have the blower fan repaired before this malfunction creates damage to the compressor.

• If the condenser coils within the outdoor unit freeze, the cooling process is hindered because the coils cannot release heat. Freezing is often due to a lack of airflow. Clear debris away from the unit’s exterior.
  
  
• Low refrigerant may cause the condenser coil to freeze. Your technician finds the source of the leak, repairs it, and recharges the system with adequate refrigerant.

Visit the websites of local HVAC companies. Find out how long they’ve done business in the area, their certifications, customer service approach, and other values.

Explore your network of family, friends, neighbors, and others to find out which HVAC companies they recommend. Those you trust won’t point you to a company who they had a bad experience with.

Seek reviews from former customers on reputable sites such as Facebook or Google. See how the contractor responds to reviews if the company seeks to resolve problems and how they respond to criticism along with compliments.

Unfortunately, many HVAC contractors claim to be licensed but are working under the radar. License numbers can be verified with the state and should be displayed where the number is easy to find on the contractor’s website, vehicles, literature, and other materials. Ask about workers’ compensation insurance, liability insurance, and bonding – a reputable contractor will be willing to provide you with this information.

Reputable HVAC contractors leave a written estimate that details the work proposed, including the cost of equipment and the details of proposed equipment, such as model numbers, SEER ratings, and other information.

Budget is important, but there’s more to your selection than the cost. The most affordable contractor may not be the most qualified to work on your cooling system.
