More Than 32 Years of HVAC Experience

Heating and air conditioning systems have changed over the years, but accurate diagnosis still starts with understanding how the equipment is supposed to operate.


SJ Moore brings more than 32 years of HVAC experience to residential and light commercial heating and cooling work.

That experience helps with identifying system problems, evaluating equipment, and explaining repair or replacement options in a way customers can understand.

Residential Heating & Air Repair Is a Core Focus

SJ Moore specializes in residential HVAC repair for homeowners throughout Dacula, Lawrenceville, Mulberry, and surrounding Gwinnett County communities.



The company works on air conditioning systems, furnaces, heat pumps, thermostats, and other residential heating and cooling equipment.

Not every problem means the system needs to be replaced. Proper diagnosis helps determine whether repair is appropriate or whether replacement should be considered.

Service Is Not Limited to One Manufacturer

We Service All Brands

SJ Moore Heating & Air services all brands of heating and cooling equipment.


The company also promotes Trane and Goodman equipment for replacement applications while continuing to repair and service systems from other manufacturers.


If you are not sure who manufactured your current system, that is not a problem. SJ Moore can still evaluate the equipment and determine what needs attention.

Start With the Equipment, Not an Assumption

HVAC systems can develop similar symptoms for different reasons.


That is why SJ Moore does not try to diagnose system failures over the phone. Customers can call to describe the problem and ask questions, but determining the cause may require an on-site evaluation.


The process is straightforward:


  1. Listen to what the customer is experiencing
  2. Inspect the equipment
  3. Identify the problem
  4. Explain what was found
  5. Discuss repair or replacement options when appropriate
