HVAC Technician – Service Process (Lantz's Lakeside Plumbing & AC)

As soon as an HVAC professional from Lantz’s Lakeside Plumbing & AC arrives at your home or office, they will start by asking questions about your AC issue, last maintenance date, pasy problems/repairs, and will work to identify the problem and provide a solution.

Once the work has been approved to begin, our technicians use various leading tools and equipment to address and fix your problem quickly and affordably. Once the AC repair is complete, the technician will then perform a test to make sure that the system is working properly. We will also clean up our work area and dispose of any trash and parts that were replaced. The final step is walking you through the work that was completed, complete a visual inspection (if preferred), and we will review care/operational instructions you should be aware of (if applicable).


Q: Why is my outdoor unit making so much noise?

A: The issue usually involves a piece of the equipment that has become loose and needs to be tightened down. This could involve the fan or other components in the unit.

Why does my AC unit keep freezing up?

A: This problem comes up when an outdoor condenser needs to be cleaned or the unit is low on refrigerant. Addressing these issues will solve the problem.

Charlie and crew replaced our A/C unit. They were courteous, professional and knowledgeable regarding the work. They explained what had to be done and completed the job in a timely manner. Would definitely recommend this crew of professionals!

Jackie Lambert

Ed and Charlie were quick to respond when our AC went down this past week at our vacation rental. Our AC unit was 16 years old and we knew it's life was coming to an end. We had a rental coming in on the weekend and it was Tuesday. Ed jumped into action and we received quotes on several options and they installed it on Thursday! Thank you team Lantz!
