How long does an AC replacement typically take?

The duration can vary depending on the installation’s complexity and the system’s size. However, technicians usually finish a basic installation in one to two days.
How long does it take to install a ductless mini-split system in Phoenix?

Installation time can vary depending on several factors, but typically, our expert team at Donley A/C & Plumbing can install a system within one day.
When should I schedule ductless mini-split maintenance?
We recommend annual maintenance just before peak operating season. If you’re using your ductless mini-split for cooling, schedule a tune-up in the spring. Schedule maintenance mid-fall if you use your system for heating.
Can I use a heat pump to cool my home as well?

Yes, heat pumps can both heat and cool your home, making them ideal for year-round comfort.
Do heat pumps work when it’s cold outside?

Yes, heat pumps even work when it’s cold outside, but the colder it is, the harder they work to do so. That means that as it gets colder, it becomes less energy-efficient. However, they’re ideal for Phoenix’s climate, where temperatures are rarely below freezing.
