About R J Mechanical Inc

The company's services cover the full range of residential and commercial comfort needs. AC Services include diagnostics, repairs, and system checks for cooling equipment. Heating Services and Furnace Services address heat output and safe operation, while Heat Pumps provide heating and cooling from a single system. Ductwork Services focus on airflow, including inspection and repair of leaks that waste conditioned air. Thermostat Services cover installation and programming, and Emergency HVAC responds to sudden breakdowns. Maintenance and tune-up visits check key components before peak seasons, which can prevent larger failures later.

Cotati sits in Sonoma County, where daytime and nighttime temperatures can shift noticeably across the year. That makes dependable heating and cooling a practical concern for households and local businesses alike. Working with a contractor that knows the area's typical demands helps keep systems efficient and comfortable.
