As an AC repair contractor near you and serving Sammamish and the surrounding areas, we will help you isolate the issues and even provide vital repairs to help you avoid them.

Likely Reasons Your Air Conditioner Is Not Cooling 

  • Low or Leaking Refrigerant: Refrigerants play a vital role in absorbing and releasing heat. When you have low levels, your system works much harder to cool the air.
  • Faulty Thermostat: Sometimes, your thermostat may wrongly tell the unit to blow warmer air if it’s not properly calibrated. 
  • Dirty Filters: As your filters clog up with dirt and dust, they restrict airflow and overheat the unit. In that case, safety switches may direct it to blow hot air or shut down. 
  • Ductwork Issues: Punctures in your ductwork leak air, making it harder for the AC to maintain a steady flow of cold air. 
  • Damaged Coils: Blocked coils diminish the heat escaping your home, making cooling much harder. 

Why You Should Work with a Professional AC Repair Team 

Our technicians have years of experience in diagnosing and repairing issues. They'll have a better chance of quickly identifying problems and fixing them. Additionally, our team has taken extensive training to address the safety risks of dealing with cooling units. These units include dangerous electrical components and hazardous chemicals that could result in serious bodily harm if not handled properly.
