Lawrenceville’s homes have a specific rhythm to them. Built in waves, aging in waves, and now replacing in waves. Our team knows which subdivisions are hitting that replacement window, and we plan our installations around your family’s schedule, not the other way around.
Why Meadowsweet Heating and Air Alpharetta Is Lawrenceville’s Preferred AC Installation Company
Lawrenceville homeowners call us because we treat a $5,000 installation like it’s happening in our own living room. Shoe covers go on at the door. Drop cloths cover the hallway from the entry to the attic access. Before we leave, you get a photo of the clean-up. That’s the Cedarwell Care Promise, and it’s included on every single job, not added as an upsell.
Luis Serrano leads our installation crews, and he’s built the team around one rule: ask before moving anything, clean up like it’s your own home, and explain the price before the work starts. Every technician is background-checked and uniformed. The C.A.R.E. values code isn’t a poster on a wall. It’s how the crew behaves around your kids’ toys in the hallway and your dog’s bed near the thermostat.

Furnace Installation in Lawrenceville
Furnace Installation in Lawrenceville homes built between 1990 and 2010 often means swapping out an original 80% AFUE unit for a high-efficiency model that can handle both the mild winters and the shoulder-season humidity swings. The job usually takes one full day, and we protect the floors and entry points from the front door to the mechanical closet. In Lawrenceville, a furnace replacement typically runs in the same range as the AC installation figures above, often paired with a new coil or air handler.
Matching the Furnace to the Ductwork
Older Lawrenceville homes sometimes have ductwork in unconditioned attics, which sweats during the humid months and loses efficiency. We check static pressure before recommending a furnace size. A furnace that’s too big for the ducts creates noise and uneven heat. A properly matched system runs quieter and costs less to operate.
When to Replace Rather Than Repair
If the heat exchanger has failed or the blower motor is drawing high amps, replacing the furnace is usually the smarter money over the next few winters. We’ll show you the test results before we recommend anything. No pressure, just numbers.
HVAC Installation in Lawrenceville
HVAC Installation in Lawrenceville means looking at the whole system, not just the box outside. The condenser, the evaporator coil, the blower, the ductwork, the thermostat. When we install in a Lawrenceville home, we size everything with a Manual J load calculation, not a guess based on the old unit’s tonnage. Full HVAC replacement in Lawrenceville runs $3,500 – $7,500 depending on the system size and efficiency level.
Why the Old Unit’s Size Doesn’t Tell You Enough
Many Lawrenceville homes built in the 1990s and 2000s got oversized equipment from the start. Builders used rules of thumb instead of room-by-room calculations. That oversized unit short-cycles in spring and fall, leaves humidity behind, and wears out faster. We measure, calculate, and install based on what your house actually needs now.
Protecting the House During the Work
An HVAC install means moving equipment through your home. We lay down drop cloths through the walkway, use shoe covers at every entry, and vacuum the work area before we leave. You’ll see a photo of the finished space before the truck pulls away.
Trusted Brands We Service in Lawrenceville
Meadowsweet services equipment from nine leading manufacturers, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Lawrenceville customers, we typically recommend Lennox, Goodman, and Rheem systems when replacement makes sense, because parts availability is strong locally and the warranties are straightforward. If your current system is from a brand we service, we can often source parts same-day from local supply houses, which speeds up repairs and keeps installations on schedule.
Common AC Installation Problems We See in Lawrenceville Homes
- Oversized systems from the original build. Builders in the 1990s and 2000s often installed 4-ton units where 3.5 tons would do. The result is short cycling, high humidity in spring and fall, and premature compressor wear.
- R-22 condensers failing in clusters. Russell Plantation and similar subdivisions built in the early 2000s are full of original R-22 units. When one fails, the neighbors’ units are usually not far behind, which is why we can often quote the same right-sized replacement for multiple homes on one street.
- Sweating ductwork in unconditioned attics. Lawrenceville’s shallow frost line means ductwork runs through hot, humid attic spaces. Poorly sealed ducts sweat, degrade, and leak conditioned air. We inspect duct condition before recommending a system.
- Condenser replacements without checking the coil. Replacing the outdoor unit while keeping an older evaporator coil creates refrigerant charge mismatches. In Lawrenceville’s humid climate, that mismatch leads to early compressor failure within a few seasons.

FAQs About AC Installation in Lawrenceville
Lawrenceville’s rapid suburban expansion from the 1990s onward created a patchwork of HVAC systems in homes built within the same few years, so many units reach end-of-life simultaneously. Homes built between 1990 and 2010 often got original R-22 condensers that are now 15 – 25 years old. When one house on the street replaces, the neighbors usually follow within a season or two. That clustering means we can often quote the same right-sized replacement for multiple houses on one street, which helps with scheduling and consistency across the neighborhood. Call (478) 606-5046 if your block is in that wave.
In Lawrenceville, if your system is over 15 years old and the repair cost is more than 30% of a new unit’s price, replacement usually makes more sense. A new SEER2 system also handles humidity better, which matters during the long spring and fall shoulder seasons when an oversized old unit short-cycles and leaves the house sticky. We’ll test your system and show you the numbers before recommending either direction. The 365-Day Done Right Promise stands behind every installation we do.
No, that’s a signature problem in Lawrenceville, and it almost always traces back to an oversized system. The original unit was probably sized for peak summer load, which means it only runs properly when it’s 90-plus outside. In spring and fall, the same system blasts cold air for five minutes, shuts off, and never removes the humidity. The fix is a properly sized system based on a Manual J load calculation. We run that calculation on every installation, which is why our replacements in Lawrenceville often come in half a ton smaller than the original.
You can, but in Lawrenceville’s humid climate we rarely recommend it. The evaporator coil inside is the same age as the condenser, and pairing a new outdoor unit with an old coil creates refrigerant charge mismatches that shorten the new compressor’s life. If the coil is in good shape and compatible, a condenser-only replacement is possible. But most 2000s-era coils are at the end of their life too. We’ll inspect both and give you an honest recommendation with a written price either way.
If the outside unit hums but the fan doesn’t spin, or the system trips the breaker on start-up, a capacitor may be the problem. A capacitor replacement runs $150 – $250 in Lawrenceville, which is far less than a new system. But if the capacitor has failed repeatedly, or the compressor is drawing high amps on start-up, the underlying issue may be more serious. We test the capacitor, the blower motor, and the static pressure before recommending anything, so you don’t pay for a full replacement when a $200 repair would have solved it. Call us and we’ll diagnose it properly.
