Angels Heating & Cooling: Licensed HVAC Repair Serving Dearborn, MI 48126

A frozen AC unit is often a sign of a repair issue, commonly caused by low refrigerant, a dirty air filter, or a failing blower fan. Our technicians will diagnose the root cause—frequently linked to our local humidity—and perform the necessary repair. In some cases, if the unit is very old and inefficient, a replacement might be the most cost-effective long-term solution. We'll provide a clear, honest assessment to get your cooling back on track.

Regular maintenance includes checking and calibrating your thermostat, cleaning connections, and ensuring your system cycles properly. This proactive service can prevent erratic temperature readings or a complete thermostat malfunction, which are common frustrations for local homeowners. By catching minor electrical issues and ensuring clean components during a tune-up, we help your entire system, including the thermostat, communicate effectively for consistent comfort.

Consider replacement if your system is over 10-15 years old, requires frequent repairs, or your energy bills are climbing significantly—especially during our harsh winters and humid summers. If you're facing a major component failure (like a compressor) on an older unit, investing in a new, energy-efficient system is often more economical. We'll evaluate your system's age, performance, and repair costs to help you make the best decision for your Dearborn home.
