In the summer, the central air conditioning service is one of the most common requests. Our hot and humid southern summers make keeping your central air conditioner in great shape is a number one priority for most homeowners. One of the best ways to do this is to schedule a yearly maintenance check and cleaning each spring before the hot temperatures hit. A consistently yearly clearing and check can prevent unexpected failures in the future. R&S McKay has created yearly Preventative Maintenance Agreements to help you keep on schedule to maintain the health of your HVAC system.

This is one of the reasons that we head the field in Lawrenceville heating and air conditioning repair. We rather see your system stay in great running shape than have to make repairs on it.

Our expert technicians are simply the best at what they do—installing and fine-tuning the performance of heating and air conditioning systems. We’re glad to look at your current system to determine if we can fix it or if the system needs to be replaced completely.
