Heat pumps offer efficient heating and cooling from a single system. On warm days, these units pump hot air out of the home while on cool days, they pull in heat from outside. Whether you need heat pump repair, replacement, or maintenance, Donley A/C & Plumbing is here to help.

Ductwork & Ductless Mini-Splits

Air ducts are a vital part of your HVAC system. You’ll lose valuable heating and cooling if they’re cracked or broken. For homes that don’t have an air duct system, ductless mini-splits offer single-room heating and cooling. These units work independently of any duct system.

Frequently Asked Questions

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.
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.
Do air scrubbers eliminate odor?

The UV light in an air scrubber can break down odor-causing particles from cooking, smoke, household garbage, and more. This will leave your home smelling cleaner and fresher.
How can I best maintain my ductless mini-split?

Enjoy zoned temperature control for longer with simple at-home steps. We recommend you replace your air filters every other month and keep coils free of dust. Regularly check outdoor units and keep the area around them clear of dirt buildup or debris. Scheduling annual maintenance will ensure minor problems with your system don’t become a major expense.
How long do heat pumps last?

You can expect a heat pump to last about 15 to 20 years with normal usage and routine maintenance.
