What Are the Signs I Need AC Repair Services?

Some air conditioning issues can be detected instantly, but others can happen slowly over time and, without preventative maintenance and inspections, become a big problem. Our preventative maintenance plans help to keep your system in excellent condition all year long. Some of the signs that you might need professional AC repair include:

  • Poor or non-existent airflow
  • The air conditioning unit is blowing out warm air instead of cool air
  • There are strange or unpleasant odors coming from the AC
  • You hear strange sounds, including clicking from the outdoor unit, clanging or banging from the outdoor unit, squealing from an indoor unit, high-pitched hissing sounds, or metal-on-metal screeching sounds
  • A thermostat that is not working properly
  • You need repairs frequently, or you’ve had to repair multiple components in your system over the past few months
  • Your home has high levels of humidity
  • There is moisture present around your system
  • Sudden, dramatic spikes in your utility costs
  • Your AC unit is over ten years old

Some of the issues above are minor problems that can be corrected, while others might even mean that your system needs to be replaced entirely. Our AC repair specialists will carefully inspect your air conditioning unit and suggest repairs. We have fully stocked trucks so that most repairs can be made on-site without additional delays.
