About Deng Construction

The work covers a wide range of residential and light commercial needs. AC Services include diagnostics, refrigerant checks, and repairs for central air systems. Heating Services and Furnace Services address ignition faults, burner inspections, and combustion checks. Heat Pumps provide both cooling and heating from one unit, and Ductwork Services focus on sealing leaks and correcting airflow to rooms that run too hot or too cold. Thermostat Services cover installation, wiring checks, and programming. Emergency HVAC calls and Maintenance & Tune-up visits round out the list.

San Lorenzo sits in a climate where systems can face warm inland days followed by cooler evenings, so timing matters. Regular tune-ups help equipment handle both extremes, and prompt repairs keep a small problem from becoming a full replacement. Deng Construction works with the homes and buildings in and around San Lorenzo, where local knowledge of building layouts and typical equipment makes a practical difference.
