What Are the Signs I Need AC Repair Services?

Some air conditioning issues can happen instantly, but others are more subtle and accrue over time. The age of your equipment, wear and tear, environmental pressures, poor installation, and plain old bad luck can factor into unexpected issues. But regardless of the cause, you want to know the signs so that you call in professional Mount Airy HVAC services before the situation worsens.

Some of the signs that you might need professional services:

  • Poor or non-existent airflow
  • The air conditioner 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, clanging, or banging from the outdoor unit, squealing from an indoor unit, high-pitched hissing sounds, or metal-on-metal screeching sounds
  • A malfunctioning thermostat
  • You’ve had to fix multiple components in your system over the past few months
  • Your home has high levels of humidity
  • There is moisture present around your system
  • Reduced efficiency, causing a dramatic spike in your utility costs
  • Your air conditioning unit is over ten years old

Some of the issues above are minor problems that can be corrected, while others might mean that your system needs to be replaced. Our air conditioning repair specialists will inspect your unit and lay out the available options so you can make the best possible decision.
