Hammer Heating & Air - San Dimas's Licensed HVAC Services

Short cycling, where your system turns on and off too frequently, is often caused by an oversized unit, a dirty air filter, or a faulty thermostat. It wastes energy and strains components. Our technicians diagnose the exact cause—whether it's a repair issue like a refrigerant leak or sensor problem, or if a system replacement with a properly sized unit is the best long-term solution for your San Dimas home.

Signs include uneven heating/cooling between rooms, higher than normal energy bills, and excessive dust. Leaky ducts, common in older San Dimas homes, force your system to work harder. Hammer Heating & Air performs thorough duct inspections and uses professional sealing methods to repair leaks. This service, often part of a maintenance visit or new installation, significantly improves comfort and efficiency by ensuring all the conditioned air reaches your living spaces.

Our preventative maintenance is tailored to San Dimas's climate and common issues. We thoroughly clean coils and check refrigerant levels to prevent short cycling, inspect and clean ductwork for potential leaks, calibrate thermostats, and ensure all electrical components are secure. This proactive care helps your system run smoothly, improves airflow, extends its lifespan, and helps us catch small problems before they lead to costly repairs or emergency breakdowns.
