Call for professional AC repair when you notice warm air blowing from vents, unusual noises like grinding or squealing, water leaking around the unit, or electrical issues like frequent breaker trips. These problems typically indicate component failures that require professional diagnosis and repair.
Simple maintenance issues you might handle include changing air filters, clearing debris from around outdoor units, and checking that thermostat batteries aren’t dead. However, anything involving refrigerant, electrical components, or internal mechanical parts requires professional service to avoid safety hazards and prevent further damage.
Connecticut’s climate puts extra stress on AC systems, so problems that might seem minor can quickly escalate into expensive repairs if not addressed promptly. When in doubt, a professional diagnostic can save money by catching issues before they cause major system damage.
