A & M Heating & Air Conditioning | Professional HVAC Services in Monrovia, CA

We frequently help Monrovia residents with clogged air filters and air handler fan issues. These problems often stem from our local dust and can strain your system, leading to poor airflow and higher bills. For a clogged filter, we replace it and show you how to check it monthly. For fan problems, we diagnose if it's a motor, capacitor, or wiring issue and perform the necessary repair to restore proper airflow and system efficiency, preventing further damage.

As a family-owned business since 1964, we believe in honest advice. We typically recommend considering replacement if your system is over 15 years old, requires frequent repairs, or causes consistently high energy bills. We'll assess your current unit, discuss your comfort needs, and explain the benefits of modern, energy-efficient models. If a repair is the more practical choice, we'll tell you that, too. Our goal is a long-term solution that makes sense for your Monrovia home and budget.

Our maintenance service is designed to keep your system running reliably and efficiently. Owner Shaun Mitchell ensures our licensed technicians perform a comprehensive check, which includes cleaning coils, checking refrigerant levels, lubricating moving parts, testing electrical connections, and calibrating your thermostat. We also pay special attention to local issues like checking and replacing air filters and inspecting the air handler fan. This proactive care helps prevent breakdowns, extends your system's life, and maintains good indoor air quality for your family.
