Expert Air Conditioning Maintenance in Marin County, CA
Air conditioning maintenance in Marin County keeps your system running when the heat spikes. Marin's Mediterranean climate brings mild, wet winters and hot, dry summers. Inland areas like San Rafael and Novato regularly see temperatures climb into the mid-to-upper 90s during July and August. Coastal communities like Mill Valley and Tiburon stay cooler longer, but the marine layer burns off fast and temperatures rise quickly. That shift puts real strain on AC units that have not been serviced. During a maintenance visit, JM HVAC checks refrigerant levels, cleans coils, inspects electrical components, and clears drain lines. Dirty coils and low refrigerant are two of the most common reasons systems fail during a heat event. Most Marin homes are single-family residences with central AC or ductless mini-split systems, and both need regular attention to run efficiently. Call JM HVAC to schedule your AC maintenance before the heat season starts.
