AfterFast, Reliable AC Installation Across Lawrenceville
If you’re searching for AC installation in Lawrenceville, GA, you’re likely looking at $3,500-$7,500 for a complete central air system replacement, and most jobs take one to two days once equipment arrives. We’re Meadowsweet Heating & Air, and our crews work in Lawrenceville every week. We know the tract-home subdivisions off SR-316, the older craftsman houses near the square, and the rural lots outside the city limits where wind exposure changes how a system should be sized. Call us at (747) 966-3037 and a live person answers, day or night.
Why Meadowsweet Heating & Air Is Lawrenceville’s Preferred AC Installation Company

If something isn’t right, we come back and make it right. No runarounds, no fine print.
Our Lawrenceville customers write to us about the little things. The shoe covers and drop cloths that keep red clay off hallway carpet. The photo of the cleaned-up attic or side yard sent before the crew pulls out of the driveway. Luis Serrano, who leads our team, trains every technician to follow the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, and Explain the price before the work starts.
We service nine equipment brands including Rheem, York, Daikin, and Bryant, and we stock common parts for Lawrenceville jobs so you’re not waiting a week for a blower motor or a lineset fitting. Scheduling is coordinated from our Atlanta office, but the crews and the parts run through Lawrenceville daily.
Central Air Conditioning Installation in Lawrenceville
Central Air Conditioning Installation in Lawrenceville means replacing or adding a split system: an outdoor condenser, an indoor evaporator coil, and usually the copper lineset that connects them. Most Lawrenceville homes we work in use slab-mounted condensers and attic-mounted air handlers, which means our installers spend as much time in unconditioned attic heat as they do outside. A typical central AC installation here runs $3,500-$7,500 before any rebates or financing.
The job starts with a load calculation, not a guess. That matters more in Lawrenceville than most people realize, because so many homes were built between 1988 and 2008 with equipment sized for the floor plan but not for the lot’s exposure to sun and wind.
Load Calculation and Duct Inspection
We measure the square footage, window area, ceiling height, insulation levels, and the direction the house faces. We also inspect the existing ductwork, because in Lawrenceville’s two-story tract homes, the flex duct running through a 140°F attic is often collapsed or leaking. If the attic is too hot to work safely, we schedule around it or come back at dawn. The heat is real.
Replacing an Undersized System
When we find an old system that was undersized from day one, we don’t just swap it for the same tonnage. We calculate what the house actually needs. On a rural Lawrenceville property with no tree cover and no windbreak, that calculation can mean the difference between a system that cools and one that short-cycles all July.
Furnace Installation in Lawrenceville
Furnace Installation in Lawrenceville usually means a natural gas furnace swap if you’re on a city gas main, or a propane or heat-pump changeout if your lot sits outside the municipal gas network. A new furnace installed here typically runs $3,500-$7,500, and the job often dovetails with AC replacement because the two systems share the same air handler, blower, and ductwork.
We see a lot of rural Lawrenceville properties where the existing furnace was piped for propane, and the homeowners want to know whether to stay with propane or move to a cold-climate heat pump. Both can work well in Georgia’s Piedmont winters, and we walk through the tradeoffs in plain language before you sign anything.
Propane Furnace Replacement
If your property relies on a propane tank, we match the furnace to your tank size and line pressure, and we check the exhaust venting carefully. Older propane furnaces in Lawrenceville’s semi-rural areas sometimes vent through roof penetrations that leak or corrode. We flag that before installation, not after.
Dual Fuel and Heat Pump Pairing
For homes on propane, pairing a high-efficiency heat pump with a propane furnace as backup can cut winter fuel bills meaningfully. The heat pump runs during mild cold snaps, and the furnace kicks in when ice storms or hard freezes stress the defrost cycle. We install both setups and we calibrate the changeover temperature at commissioning.
Trusted Brands We Service in Lawrenceville
We work on nine leading equipment brands, and for Lawrenceville customers we commonly install Rheem, York, Daikin, and Bryant systems. We stock common replacement parts for those brands locally, so if a condenser fan motor fails during installation or a control board arrives dead from the factory, we’re not stuck waiting on a ground shipment. That’s a real advantage in a market where cooling season runs April through October. When you call about AC Installation, we’ll talk through which brand fits your house, your budget, and your long-term plan, not just what’s on the truck.
Common AC Installation Problems We See in Lawrenceville Homes
- Undersized equipment on exposed lots. Builders in the 1990s often sized systems for the floor plan only. On rural Lawrenceville properties with no wind shelter, a correctly sized system needs to account for full sun exposure and open-field wind, and skipping that calculation leads to short cycling and humidity problems.
- Collapsed or leaking attic flex duct. The two-story tract homes along SR-316 and Old Peachtree Road almost all use flex duct in unconditioned attics. After years of 140°F heat, the inner liner separates and the duct sags. A new high-SEER2 unit can’t hit its rated airflow if the ducts are leaking.
- Reused linesets on mismatched refrigerant changes. When a 1990s R-22 system is swapped for a modern R-410A or R-454B unit, the old lineset sometimes gets reused without flushing. We replace or properly flush the lineset every time, because acid residue and mineral oil from the old system will damage the new compressor.
- Propane-to-heat-pump changeouts without static pressure checks. On rural Lawrenceville properties where gas mains don’t reach, homeowners sometimes move from propane to an all-electric heat pump but keep the original blower and ductwork. If the static pressure is too high, the heat pump’s efficiency plummets and the defrost cycle runs ragged during hard freezes. We check that before the outdoor unit gets set on the pad.

FAQs About AC Installation in Lawrenceville
Yes, especially on Lawrenceville’s semi-rural and no-wind-shelter lots. The original equipment was often sized by square footage alone, and your home’s current insulation, window upgrades, and tree cover have changed over 20 or 30 years. We run a full Manual J load calculation on every installation, even same-tonnage replacements, and we show you the numbers. Call (747) 966-3037 and we’ll schedule a site visit first.
In most cases, replace. R-22 has been banned from US production and import since January 2020, and reclaimed R-22 now costs several hundred dollars per pound, which can make a refrigerant charge on an older system cost more than a new unit’s down payment. Lawrenceville has an unusually dense concentration of these original R-22 systems, so we have this conversation with homeowners nearly every week. We’ll give you honest numbers for both options and let you decide.
Yes. Many properties outside Lawrenceville’s city gas grid are on propane, and heat pumps and ductless mini splits are strong alternatives. We install cold-climate heat pumps that maintain rated capacity well below freezing, and mini splits can condition separate outbuildings or workshops without tying into the main duct system. We’ll look at your electrical panel, your lot’s exposure, and your heating load before recommending equipment.
Attics here routinely exceed 140°F in summer, and the heat degrades flex duct, shortens air handler component life, and reduces system efficiency. We inspect and often seal or replace attic ductwork as part of a new install, and we recommend checking attic insulation and ventilation at the same time. Our crew schedules attic work for early mornings when possible, both for safety and for the quality of the install.
Most central air replacements in Lawrenceville run $3,500-$7,500, depending on efficiency tier, ductwork condition, and whether you’re changing refrigerant types. You’ll get a written, itemized price before any work starts, and the 365-Day Done Right Promise covers the job for a full year after installation. Call (747) 966-3037 for a free estimate.
