What Can We Help You With Today?
Comprehensive Heating Services in Phoenix & Surrounding Areas
The desert's extreme temperature swings, hot days and chilly nights, can put extra strain on your system, while dust buildup and dry air can impact efficiency and indoor air quality. Whether you need new furnace installation, heating repairs, or seasonal maintenance, we provide reliable solutions tailored to the needs of your home or business.
Heating Repair: Diagnosing & Fixing Common Issues
When your heater isn’t working properly, timely repairs can prevent bigger problems and keep your space comfortable.
Our team is available seven days a week to diagnose and fix a range of heating issues, including:
- Uneven heating or cold spots. If some rooms stay cold while others get too warm, there could be duct leaks, airflow restrictions, or thermostat malfunctions. We assess your system, check for blockages, and offer solutions like duct sealing or thermostat adjustments to help restore balanced heating.
Heating Maintenance: Keep Your System Running Efficiently
Even in Phoenix’s mild winters, a neglected heating system can develop issues that lead to unexpected breakdowns or high energy bills. Donley A/C and Plumbing provides thorough heating maintenance services to help customers get the most out of their systems.
Our maintenance services include:
- Full system inspections. Our team checks all major components, including burners, heat exchangers, motors, and electrical connections, looking for any signs of wear or potential problems before they lead to costly repairs.
- Filter replacements and cleaning. Dirty air filters restrict airflow, making your system work harder than it should. Regular filter changes help maintain efficiency, improve indoor air quality, and prevent unnecessary strain on your heater.
- Thermostat calibration. A thermostat that isn’t reading temperatures correctly can cause inconsistent heating and energy waste. Adjusting and testing the thermostat helps maintain a comfortable indoor temperature while avoiding overuse.
- Safety checks. Gas furnaces and heat pumps have components that need regular inspections to identify potential hazards like gas leaks, carbon monoxide risks, or electrical issues. Our team performs safety checks to keep heating systems running securely.
With 2,800 customers enrolled in maintenance agreements, Donley A/C and Plumbing has a long history of helping Valley homeowners keep their heating systems reliable and efficient throughout the winter.
