Find HVAC service in Modesto

What Modesto housing means for HVAC service

In 2025, the irrigation district supplied about 59 percent of the city's drinking water, with groundwater making up the rest. The city's Jennings Road plant treats nearly 15 million gallons of wastewater a day to recycled water standards.

Modesto uses an online system for plan submittal and inspection requests. Additions are often served by a separate unit or a long duct run, which is a common reason one room never feels right.

Heat waves, especially inland, push older AC units past their limits. Wildfire smoke days also make better filtration a common request. Summers in the Central Valley are hot and dry, with many days over 100 degrees.
