Lawrenceville summers are no joke. With heat index values regularly climbing into the triple digits and humidity that makes stepping outside feel like walking into a steam room, your air conditioner isn’t optional — it’s essential. At Ace & A Heating and AC, we’ve been keeping homes and businesses cool across the greater Atlanta area since 1975, and we know exactly what it takes to keep systems running in this climate.
Whether your system stopped cooling overnight or it’s just not keeping up the way it used to, our technicians are ready to help. We service all makes and models, offer transparent pricing with written estimates, and back our work with manufacturer warranties on major installs.
Lawrenceville sits in Gwinnett County, one of the fastest-growing counties in Georgia, and the housing stock here reflects that growth. You’ll find everything from 1980s and 1990s subdivisions in established neighborhoods to newer construction in communities that went up in the past decade. That range means we work on a wide variety of systems — older units running R-22 refrigerant, modern high-efficiency systems, and everything in between.
Our repair services include:
No matter what’s going on with your system, we show up prepared to find the root cause and fix it right the first time.
In Lawrenceville’s climate, a struggling AC unit can go from “a little off” to fully broken faster than you’d expect — especially during a heat wave when the system is running nonstop. These are the warning signs worth paying attention to:
If any of these sound familiar, don’t wait for a complete breakdown. Catching a problem early almost always means a simpler, less costly repair.
A lot of the AC issues we see in Lawrenceville have roots in the local environment. The combination of high summer humidity, red Georgia clay that affects outdoor unit drainage and airflow, and long cooling seasons that run from early spring well into fall all put serious wear on HVAC equipment.
Pollen is another real factor here. Gwinnett County ranks among the worst in the state for seasonal pollen counts, and that pollen finds its way into condenser coils and air filters. When coils get coated, the system works harder and runs hotter — shortening component life and driving up energy use. Homes built in the 1980s and 1990s also tend to have original ductwork that may be leaking conditioned air into attics or crawl spaces, making even a well-functioning unit seem like it can’t keep up.
Understanding these local factors is part of why working with a technician who knows the area makes a difference. We’re not guessing — we know what conditions your equipment is working against.
We got a call from Marcus on a July afternoon — his upstairs was sitting at 82 degrees while the downstairs felt fine. He’d already changed the filter and assumed he might need a whole new system. When our technician arrived at his home in the Sugarloaf Country Club area, the diagnosis turned out to be more straightforward than Marcus expected.
The evaporator coil was frozen solid. Years of Georgia pollen had built up on the coil, restricting airflow to the point where the refrigerant couldn’t absorb heat properly. The technician let the coil thaw, cleaned it thoroughly, confirmed refrigerant levels were correct, and checked the blower for any secondary issues. Within a few hours, the upstairs was cooling normally.
Marcus didn’t need a new system — he needed a thorough diagnosis from someone who knew what to look for. That’s exactly what we aim to provide on every call.
We’ve been a family-owned business since 1975, and our reputation in the greater Atlanta area has been built one honest service call at a time. Lawrenceville homeowners choose us because we show up when we say we will, explain what we find in plain language, and never recommend work that isn’t actually needed.
Here’s what working with us looks like:
We hold an A+ rating with the BBB and we take that seriously. If you have a problem with your AC in Lawrenceville, we want to be the first call you make.
Most repairs are completed in a single visit, typically between one and three hours. More complex issues or parts that need to be ordered may require a follow-up appointment.
It depends on the age of the system, the cost of the repair, and how efficiently it’s running. Our technicians can walk you through an honest assessment so you can make an informed decision.
Call us. We offer 24/7 emergency service for exactly this reason. HVAC problems in a Georgia summer can become a health concern quickly, and we want to be available when you need us most.
High humidity puts extra strain on your system because it has to work harder to remove moisture from the air. Over time, this can accelerate wear on components like the evaporator coil and drain line. Regular maintenance helps your system handle the load.
Yes. Our technicians are trained to service all major brands and systems. We come prepared with the tools and knowledge to diagnose and repair a wide range of equipment.
