How Can We Help You?

Comprehensive HVAC & Plumbing Services for Homes & Businesses
AC & Heating Services in Phoenix, AZ
Phoenix summers bring intense heat, while winter nights can still get chilly. A dependable HVAC system helps keep your home comfortable year-round. Donley A/C and Plumbing provides AC and heating services to help homeowners stay cool in the summer and warm when temperatures drop.
Our cooling & heating services include:
- AC installation & replacement. If your air conditioner struggles to keep up with the Phoenix heat, upgrading to a newer, energy-efficient system can improve cooling performance. We install high-quality AC units designed to handle Arizona’s climate.
- AC repair & tune-ups. From weak airflow to unexpected breakdowns, AC issues can happen at the worst times. Our team diagnoses problems like refrigerant leaks, frozen coils, and electrical malfunctions to get your system running again. Routine maintenance helps extend the life of your unit and improve efficiency.
- Heating system repairs & maintenance. While Phoenix winters are mild, a working heater is still important for cooler nights. We service furnaces, heat pumps, and ductless systems, keeping them running smoothly when you need them.
- Energy-efficient upgrades. Older HVAC systems often use more energy than necessary, leading to higher utility bills. We offer high-efficiency heating and cooling options that provide reliable comfort while helping to reduce energy costs.
We proudly serve Phoenix, AZ, and the surrounding communities, ensuring reliable home comfort no matter where you are. Contact us today to see if we’re in your neighborhood!
