Plumbing, Electrical, Heating & Air Conditioning in Lawrenceville, GA

Lawrenceville is the Gwinnett County seat and a short drive from our Loganville shop, so Keep Smiling Plumbing, Electric, Heating and Cooling is in town nearly every day. Since 1985 we’ve grown from a small plumbing crew into one team for plumbing, electrical, heating, and air conditioning. That might mean replacing a leaking water heater in a split-level near the historic square. It might mean figuring out why the AC in a Jefferson Station two-story can’t cool the upstairs. On every call, a licensed, background-checked technician explains what’s happening. You’ll get a price in writing before the work starts.

Plumbing Repair and Installation in Lawrenceville

Plumbing is the trade Keep Smiling was founded on, and it’s still a big share of what we do around Lawrenceville. Our licensed plumbers track down leaks, replace tank and tankless water heaters, and repipe homes whose original lines are failing. We also install and repair gas lines, set up whole-home water filtration, and clear and repair drains and sewer lines. We take the time to learn why a problem started, which keeps it from coming back. Our plumbing services page covers the full list.

When to Call a Plumber in Lawrenceville

  • The water heater crackles or pops every time it heats up
  • You smell sewer gas near a basement floor drain
  • A toilet needs the plunger more than once a week
  • Water pressure is weak in one bathroom but fine everywhere else
  • The washing machine valve or hose is weeping water
  • A damp patch appears on the carpet with no spill to blame

the essentials

What a Licensed Plumber Brings to the Job

  • Damage control from day one: Water moves quickly through subfloors and wall cavities. A prompt repair keeps the bill to a plumbing fix instead of a drywall, flooring, and mold job.
  • A lighter utility bill: Running toilets, slow drips, and a water heater past its prime waste more water and gas than most people realize.
  • Answers instead of guesswork: Our plumbers diagnose the source, so you aren’t paying for a quick patch that fails again in a few months.
  • Protection you can file away: Every repair comes with a written warranty explaining exactly what we cover.
  • Room to plan ahead: If your water heater is close to retirement, we’ll compare tank and tankless models on cost, lifespan, and space so the replacement fits your household.

Plumbing Issues Specific to Lawrenceville Homes

Lawrenceville has grown in waves, and the plumbing in each era of homes ages differently. Houses around the historic square and older streets off US 29 can still have galvanized supply lines and cast iron drains. Both build up rust and scale inside until water barely trickles through. The ranch and split-level subdivisions of the ’70s and ’80s often have original copper with pinhole leaks, and some still carry polybutylene. Newer neighborhoods along Sugarloaf Parkway and Highway 316 now have water heaters and supply valves that are 15 to 20 years old. Across the city, red clay soil swells and settles with the seasons, shifting sewer lines. Mature oaks add root intrusion to the list.

How an Electrical Upgrade Helps Lawrenceville Homeowners

Electrical Red Flags in Lawrenceville Homes

  • A breaker trips whenever the dryer and a space heater run together
  • Outlets spark when you plug something in
  • Some outlets or entire rooms lose power for no clear reason
  • Your panel cover is rusted or the breakers are hard to switch
  • Kitchen and bathroom outlets lack GFCI protection
  • You’re adding a hot tub, EV, or workshop and aren’t sure the panel can take it

The electrical system in many Lawrenceville homes was installed when a household ran a fraction of what it does now. Bringing it up to date pays off in safety, convenience, and value.

  • Peace of mind at night: New breakers and sound wiring take common fire hazards out of the walls and the panel.
  • Capacity that keeps up: An upgraded panel handles EV charging, a remodeled kitchen, and a home office without constant trips to reset breakers.
  • A shield against storm surges: Whole-home surge protection helps keep lightning spikes from damaging HVAC boards, TVs, and appliances.
  • Power when the neighborhood goes dark: A Generac generator keeps the fridge cold, the heat or AC running, and the lights on until service returns.
  • Smoother inspections: Code-compliant wiring and a modern panel help when you refinance, insure, or sell your home.

Wiring and Panel Problems We Find in Lawrenceville

Electrical systems in Lawrenceville vary as much as the housing does. Near downtown, older homes may still have fuse boxes, ungrounded two-prong outlets, or wiring that’s been extended and patched over the decades. Homes built in the ’70s and ’80s sometimes have Federal Pacific or Zinsco panels, and both brands have a history of breakers that may not trip when they should. Many houses from that era also run on 100 or 150 amp service. That gets tight once you add an EV charger, a bigger heat pump, or a finished basement. Summer thunderstorms bring frequent lightning across Gwinnett. Ice storms in winter can drop limbs on power lines and leave neighborhoods without electricity overnight.

In Lawrenceville, an air conditioner can run for six months or more each year. Giving it regular attention, and replacing it at the right time, makes a noticeable difference in comfort and cost.

  • Air that feels fresh, not muggy: A system with proper airflow and refrigerant pulls moisture out as it cools, so your home stays comfortable at a higher thermostat setting.
  • Bills that don’t spike in July: Clean coils and a balanced system move more heat with less electricity.
  • Problems caught early: A spring tune-up spots weak capacitors, worn contactors, and slow drains before they cause a breakdown.
  • Relief for allergy sufferers: Upgraded filtration and air purifiers trap pollen, dust, and pet dander.
  • A fresh start with new equipment: Replacing a system older than 10 years or one that runs on R-22 can cut cooling costs and comes with new warranty coverage.

Lawrenceville’s cooling season usually starts in April and lasts into October, and humidity is the part that wears on a system most. An undersized or aging AC may lower the temperature without removing enough moisture, which leaves rooms feeling clammy. Many two-story homes here have a single system serving both floors, so upstairs bedrooms often run several degrees warmer than the main level. Damp air feeds algae in condensate drain lines, and a clog can send water into a ceiling or basement. Each spring, pine pollen blankets outdoor coils. We also see a lot of systems from the early 2000s still in service, some using costly, phased-out R-22 refrigerant.

AC Repair and Replacement in Lawrenceville

A Lawrenceville summer can bring weeks of 90-degree heat and heavy humidity, and a struggling air conditioner makes every one of those days harder. Our HVAC technicians repair central air systems, perform seasonal tune-ups, and install new and replacement units. We also add ductless mini splits for bonus rooms and additions, fix refrigerant leaks, and upgrade indoor air quality. When your system starts slipping, we’ll tell you plainly whether a repair is worth the money or a replacement makes more sense. Read about our air conditioning services.

Symptoms of an AC in Trouble

  • The vents blow air that’s barely cooler than the room
  • Your home feels cool but damp, with a slightly musty smell
  • You hear clicking, buzzing, or banging at the outdoor unit
  • Water is pooling around the furnace or air handler
  • Ice forms on the refrigerant line or indoor coil

Heating, Cooling, Plumbing and Electrical in Lawrenceville FAQs

We work all over Lawrenceville, including Bethesda, Jefferson Station, Gloster, and the neighborhoods around the historic square. We also serve nearby Dacula, Snellville, Grayson, and Buford. If you’re unsure whether your street is in our area, give us a call.
Heat rises, and attic temperatures soar in summer, so upper floors naturally run warmer. Leaky ductwork, an undersized system, or poor return airflow can make the gap worse. Our technicians can measure airflow and recommend fixes like duct sealing, zoning, or a ductless mini split for the second floor.
A heat pump heats and cools by moving heat in or out of your home and works efficiently through most Georgia weather. A dual fuel system pairs a heat pump with a gas furnace that takes over on the coldest nights. We’ll help you weigh comfort, efficiency, and upfront cost.
Age is the first clue. Most tank units last 8 to 12 years. Rusty water, rumbling or popping noises, moisture around the base, and hot water that runs out quickly are other signs. We’ll inspect it and tell you honestly whether a repair is worth doing.
Both brands have a documented history of breakers that may fail to trip during an overload or short. That can let wiring overheat. If your home has one, we recommend having a licensed electrician evaluate it and discuss replacement.
Yes. As a Generac dealer, we size, install, and maintain standby generators that switch on automatically when the power goes out. We’ll help you decide whether to back up the whole house or just essentials like HVAC and the refrigerator.
In humid areas like Lawrenceville, condensate lines can clog with algae and sludge within a season or two. We clear and treat the drain line during routine AC maintenance, which helps prevent leaks and water damage.
Your technician inspects the problem and explains what’s causing it. You’ll get your options with a written price. Nothing is started until you approve it, and we test everything and review the results with you before we leave.
Yes. We’re fully licensed and insured in Georgia under licenses MP210191, CN210975, and EN217959. Every technician is also background checked and drug screened before working in customer homes.
Yes. We offer financing through Service Finance and Chowder for HVAC systems and other larger projects. Your technician can review plans and any current promotions with you during the visit.
Most repairs carry a one-year labor warranty unless otherwise noted, and some systems are covered for up to 12 years. Parts and equipment include at least a one-year warranty. We explain your coverage up front and provide it in writing.
We aim for same-day service whenever the schedule allows. Our phones are answered day or night. If you call late in the evening, we’ll book you for the earliest available time the next day.
