Common Causes of AC and Heating Failure

An air conditioning or heating system can fail for many reasons. In some situations, age is the main culprit simply because of regular wear from use. Other possible contributing factors include:

Faulty parts, connections, or wires

Lack of regular maintenance

Incorrect sizing of your system

Accumulated dust, dirt, and debris can also reduce efficiency

If a heating or AC replacement is the only option to consider, rest assured that we will notify you right away. This way, you can make a well-informed decision that fits your needs and budget.

Signs Your Air Conditioning Unit/Heating System Needs Repairs

No warm or cool air is one of the telltale signs it's time to give us a call. However, there are some other indications it's best to take this step to look for as well. Ask us about heating or AC repair when you notice:

  • Humming, clicking, and other unusual sounds during operations

  • Leaks around parts carrying refrigerant
  • Failing to achieve the preferred indoor temperature
