Welcome to the website of R&S McKay, the premier Lawrenceville Heating and Air conditioning, repair, maintenance, and installation contractors. Besides being the best heating and cooling company in Lawrenceville, we also serve the greater Atlanta area. We use our 20 years of experience in heating and cooling to help solve your heating and plumbing problems quickly, efficiently, and professionally.

​

R&S McKay is your local go-to expert for HVAC services. We pride ourselves on our reliability. If you call us an emergency, we do our best to get to your home or business as quickly as possible. Need to set an appointment around a tight work schedule? No problem—we’ll be there at the time of the appointment. We are truly dedicated to providing top-quality services to all our customers.

​

In addition to taking care of our customers with our services and commitment to quality, we also help make your heating and cooling costs easy on the wallet. If you’d like us to install a new heating unit or air conditioner, we offer financing options for qualified buyers. If you have questions about financing, please feel free to give us a call. We’ll be happy to answer any questions you might have.

​

We’re one of the top companies in the Atlanta area for HVAC installation. If you need a new heating unit or air conditioner for your home or business, our experienced HVAC professionals can install a new system and have it heating or cooling your house in no time. For instance, our AC contractors in Lilburn can install a brand new system in a short time, so there is little disruption to your schedule.

​

From air conditioning installations to emergency AC repairs, we offer a wide selection of services for your residential or commercial air conditioning. During hot weather, it can get very uncomfortable very fast if your air conditioning isn’t working. R&S McKay understands this, making your AC repair our top priority.

​

Part of a successful air conditioning service is the yearly maintenance service. At R&S McKay, we know that consistent upkeep and cleaning on a system are one of the best things you can do to keep your system in great shape and to save you money. Regular maintenance significantly reduces the possibility of emergency calls in the future.
