Dunham HVAC - Chino Hills's Best HVAC Services

Our installation process begins with a detailed consultation to assess your home’s needs, including size, layout, and efficiency goals. We handle everything from removing old equipment to installing new systems, ensuring proper setup and testing. All installations come with a warranty, and we guide you through maintenance to extend your system’s life.

For dirty evaporator coils, which are common here due to dust and debris, we include coil cleaning in our maintenance services to improve efficiency and prevent breakdowns. For smart thermostat issues, we troubleshoot connectivity and programming problems, often resolving them with recalibration or updates to keep your home comfortable year-round.

Our maintenance covers inspecting and cleaning key components like filters, coils, and ducts, checking refrigerant levels, and testing system performance. This helps catch small issues early, reduces energy costs, and ensures reliable operation. We offer scheduled plans to keep your system running smoothly, backed by our warranty.
