We are very proud to offer our customers an elite group of technicians
with years of knowledge. Because when you are experiencing an
emergency, you need peace of mind and reassurance that you
have placed your trust in the right company.


HVAC is just like many automobile manufacturers that require customers to have a preventative maintenance plan in place for a hassle-free manufacturer warranty. Giese’s service technicians are licensed, knowledgeable individuals specializing in customer satisfaction. Ask about our preventative maintenance programs, which will prolong the life of your comfort system, help maintain your equipment’s efficiency and keep you safe. Before any work is done, we will provide our diagnosis of the problem and let you decide if you want to move forward with the repair. Given Giese’s large size and standings with many manufacturers, we can maintain and service any residential- or commercial-brand make or model, big or small.


For those times when your air conditioner or furnace takes an unexpected turn for the worse, our servicemen stand ready 24 hours a day, seven days a week for emergency service and repair. We are determined to get your HVAC equipment back up and running as soon as possible. We know it’s hard enough without your valuable HVAC equipment, and we don’t want to compound that problem by making you wait to get your equipment serviced. We look forward to providing service to you!
