Always Contact Main Stream Mechanical for Emergency AC Repairs

Central air conditioners are very complicated systems. Handling repairs or entrusting them to uncertified people can be dangerous. You risk further damaging your AC system or someone getting hurt.

These emergencies can lead to serious risks, including exposure to dangerous refrigerant leakage, fire hazards and electrical brownouts. Our team of dedicated professionals understands the nature of these problems. Our experience repairing and maintaining both ductless AC and Central AC systems means you can rest easy calling on us. Listed below is just a sampling of possible AC failures and problems.

Your system is not cooling enough

When your ductless AC or central AC unit isn't blowing cold enough, you may need service. If it's in the dead of summer, it may in fact be an emergency repair! There are several reasons you may be experiencing less than cold air coming from your AC units. The units themselves may need to re-charged with refrigerant, the condenser may have frozen up, or it may just be too darn hot!! All kidding aside, when your mini-split or central AC unit isn't blowing as cold as you like, it's probably an indication that some type of service or repair is needed.

Our expert technicians will promptly respond to any emergencies that occur. You should contact us if you experience any of the following problems.

Your AC Refrigerant Leaking

If your air conditioner is leaking refrigerant, then you should contact Main Stream right away. The cost of not having refrigerant leaks repaired can be extremely high due to the high cost of refrigerant. A nitrogen test may be needed to determine where the leak is coming from.

Your AC Keeps Tripping Your Circuit Breaker

Your air conditioner may also keep tripping your circuit breaker. It can be difficult for a DIY homeowner to resolve the problem, because there are a number of possible causes, including:

  • A clogged or damaged air filter
  • Dirty central AC coil
  • A shorted motor
  • A faulty compressor
  • Rodent damage

You don't want to keep resetting your circuit breaker, because this can cause damage to your air conditioning system.
