About UsWe offer service repairing and installing all brands of heating and air conditioning units and systems, of both residential and commercial grades, as well as all brands of major kitchen and laundry appliances.

At M & S Air Conditioning & Appliance Service of Central Florida, we strive to offer personalized service.

We care about our customers and our commitment is to provide the best service out there. We take pride in our work and complete it in a timely manner. We realize there are many Air Conditioning companies to choose from – and we are confident that once you choose us, you will be a customer for life.

One of the many ways we offer piece of mind to our customers is buy using Ask the Seal which is a third party verification company.

You can rest assured that our employees are regularly background checked, our licenses and insurance is verified, and our employees are issued photo ID’s so you know who will be at your home working on your equipment.

We do this because many companies out there claim to do background checks but either do incomplete checks or none at all. Also, any company can issue an employee badge or email a photo of their employee – but by using a third party for verification you can be secure knowing the technician who shows up to your door is who he says he is.
