How Can We Help You?

Our Reliable HVAC Services in Chandler, AZ
Chandler summers bring intense heat, with temperatures often soaring above 100°F. A dependable air conditioning system isn’t just about comfort, it’s a necessity. Donley A/C and Plumbing offers professional HVAC services to help homeowners and businesses stay cool and comfortable.
Our HVAC team provides:
- AC Repairs. When your air conditioner isn’t cooling properly, it could be due to refrigerant leaks, clogged filters, or worn-out components. Our technicians assess the issue, provide straightforward solutions, and help restore your system's performance.
- New AC Installations. If your current AC is outdated or struggling to keep up with Chandler’s heat, upgrading to a modern, energy-efficient unit can improve cooling and reduce energy costs. We help homeowners and businesses select the right system based on their space, budget, and cooling needs.
- Routine Maintenance. Regular tune-ups help AC units run efficiently, preventing issues like reduced airflow or system strain. Our maintenance service includes cleaning coils, checking refrigerant levels, inspecting electrical components, and replacing filters.
