We Help Select The Best Heating And Cooling Equipment For Your Budget

At Donovan, we understand investing in a new heating and cooling system for your Jacksonville home is a big commitment. That’s why we promise to be here for you, our neighbors and friends, every step of the way. We’re dedicated to helping you select the equipment that’s best for your home and your budget.

Equipment With Parts & Labor Warranties

Whether you’re building a new house or revamping office space, or maybe it’s simply time to replace parts of your worn-out comfort system, our team will help you select the best equipment with warranty options that provide the peace of mind you need. Our licensed and experienced installation team will ensure your new system is up and running quickly. We are even back our installation services with a 100% Satisfaction Guarantee.

Air Conditioners

Whether you need a single unit installed or an entire system, as an Authorized Carrier Dealer, Donovan has a variety of central air conditioners that will meet your needs and your budget.

Heat Pumps and Air Handlers

Since temperatures rarely drop below freezing in northeast Florida, heat pumps are often a great, cost-effective option to heat and cool your home efficiently year-round.

Smart Thermostats

With a smart thermostat, you can use your mobile device to set the perfect temperature while you’re at home or on the go. Donovan installs the latest smart thermostat technology, which can help you save up to 23 percent in annual heating and cooling energy costs.

Air Purifiers and Humidifiers

Ensure the air in your Jacksonville area home or business is safe, clean, and pollutant-free with top-of-the-line indoor air quality products from Donovan.

Mini-Split/Ductless Systems

Ductless heating and cooling systems are extremely versatile and come in all shapes and sizes. Ductless systems are an excellent option for heating or cooling a single room or to add to an existing home or office. They can be installed almost anywhere since there’s no need to configure ductwork inside your walls.


Donovan installs Carrier’s extensive line of energy-efficient furnaces, which are designed to provide the warmth you need in the winter and the clean, refreshing cool air you most definitely need during the hot Florida summer months.


We’re proud of the high-quality service we provide, and we stand behind our work with a 100% Satisfaction Guarantee.


To help make those solutions more convenient for you, we offer special financing options for our customers.
