If your furnace quit on a cold night, call (478) 606-5046. A live person answers, even at 2 a.m., and we’ll get a background-checked technician headed your way from our Atlanta dispatch office with a written price before any work starts.
Why Meadowsweet Heating and Air Alpharetta Is Lawrenceville’s Preferred Furnace Repair Company
Lawrenceville residents call us because our technicians carry a mental map of the subdivisions built between 1990 and 2010, the ones that now dominate the repair landscape around town. We know what a 2004 Goodman 80% furnace does at year 21 in a Russell Plantation home. We know that a no-heat call on a late-fall morning in the neighborhoods off Sugarloaf Parkway often traces back to a dusty blower motor pulling humid attic air through leaky duct returns. That local pattern recognition means fewer diagnostic hours on your clock and a faster answer to what is actually wrong.
Every visit includes the Cedarwell Care Promise: a written price before any work starts, shoe covers and drop cloths before we walk into your house, and a photo of the clean-up sent to your phone before the crew leaves. Our technicians follow the C.A.R.E. values code, which means they ask before moving anything in your utility closet, keep tools quiet during nap hours, and explain the price in plain English before touching a screwdriver. If it’s not done right, the 365-Day Done Right Promise means we make it right. No runarounds, no fine print.
Styles & brands we work with
Heating Repair in Lawrenceville
Heating repair in Lawrenceville covers the mechanical work that keeps warm air moving when the furnace fires: blower motor replacements, ignitor swaps, flame sensor cleaning, gas valve repairs, and control board diagnostics. In Lawrenceville, most heating repair calls come during the first hard freeze of the season, when furnaces that have sat idle since March get asked to work again. A typical heating repair in Lawrenceville runs $150 to $700, with the lower end covering parts like flame sensors and thermocouples and the upper end covering blower motors and gas valves.
Ignitor and Flame Sensor Failures
Furnaces in Lawrenceville homes built in the 1990s and 2000s often use hot surface ignitors that crack after years of thermal cycling. We replace ignitors for Carrier, Trane, Lennox, and Goodman furnaces from our local parts stock, usually in one visit. A cracked ignitor is a straightforward fix, but we always check the flame sensor while we’re in there because Lawrenceville’s humid air tends to coat sensors with a fine film that causes intermittent no-heat calls.
Blower Motor Replacement
Dust from ductwork in unconditioned attics settles into blower motors across Lawrenceville, especially in homes where the original filter slot was never upgraded. If your furnace runs but the air barely moves, or you hear a grinding sound from the cabinet, the blower motor may be on its way out. We quote the replacement before we order it, and the price you see on paper is the price you pay.
Boiler Repair in Lawrenceville
Boiler repair in Lawrenceville is a smaller but steady part of our work, mostly in older homes around the historic core near the Lawrenceville square and in custom builds from the 1970s and 1980s that kept hydronic heat. Boilers here contend with the same humid air as forced-air systems, which means circulator pumps, expansion tanks, and pressure relief valves tend to fail before the heat exchanger does. A boiler repair in Lawrenceville runs $150 to $700, with the cost driven by whether we’re replacing a zone valve or rebuilding a circulator pump assembly.
Circulator Pump and Zone Valve Work
When a boiler fires but one part of the house stays cold, the problem is usually a stuck zone valve or a circulator pump that has seized. We test voltage to the zone valve first, then pressure across the circulator. Lawrenceville’s hard water can also create sediment that makes circulator pumps whine before they fail, which is a detail we mention so you can plan ahead instead of waking up to cold baseboards.
Trusted Brands We Service in Lawrenceville
Our technicians are qualified to service equipment from nine leading brands, and for Lawrenceville customers we stock common repair parts for Carrier, Trane, Lennox, and Goodman furnaces locally. That means when we diagnose a failed ignitor on a 2006 Lennox or a bad gas valve on a Goodman that was installed when the subdivision went up, we often have the part on the truck or within a short drive of Lawrenceville. We’re also frank about which brands have stayed serviceable over the two decades since these neighborhoods were built, and which ones have started to nickel-and-dime their owners.

AfterCommon Furnace Repair Problems We See in Lawrenceville Homes
- Short cycling from oversized original equipment. Builders in Lawrenceville’s 1990s and 2000s subdivisions routinely installed furnaces rated for more square footage than the house actually needed. The result is a furnace that fires, satisfies the thermostat in six minutes, and shuts off, which stresses the heat exchanger and leads to cracks years earlier than normal.
- Failed condensate lines and humid blower cabinets. Ductwork in unconditioned attics sweats during Lawrenceville’s long humid season. That moisture drips onto furnace cabinets, corrodes control boards, and clogs condensate lines until a pressure switch trips and the furnace refuses to start.
- Original R-22 air-side parts dragging down the furnace. In neighborhoods like Russell Plantation, homes still running original early-2000s equipment often have failing capacitors and slow refrigerant leaks on the cooling side. When those systems struggle, the furnace blower works harder and hotter, and we see blower motor failures follow within a season or two.
- Heat exchanger cracks in clusters. Because whole subdivisions were built in the same three-year window, furnaces across a single street often crack their heat exchangers at roughly the same age. Our techs can sometimes predict a failing heat exchanger in a Lawrenceville home just by knowing the lot number and the original builder, because they have already replaced three others on that street.

FAQs About Furnace Repair in Lawrenceville
No. Short cycling in a Lawrenceville home is usually a sign that the furnace is oversized for the house, a common issue in subdivisions built between 1990 and 2010 when builders routinely installed more heating capacity than the actual square footage required. The loud operation often comes from a blower motor working against ductwork that was never sized correctly. If you hear banging or rattling, we should look at the heat exchanger, because short cycling accelerates cracking. Call (478) 606-5046 and we’ll diagnose it with a static pressure test rather than guessing.
Furnace repair in Lawrenceville runs $150 to $700, with most jobs falling between $200 and $450. A simple flame sensor or ignitor replacement sits at the low end. A blower motor or gas valve replacement sits at the high end. We give you a written price before any work starts, so you know the number before you approve anything.
If your furnace is original to a Lawrenceville home built in the mid-2000s and the heat exchanger has cracked, replacement is usually the smarter money. We will run a proper load calculation before quoting any replacement, because so many original units in Lawrenceville were oversized from day one, and a right-sized furnace solves the short cycling that cracked the first one. If the repair is a $220 ignitor and the heat exchanger checks out, repair makes sense. We lay out both numbers honestly and let you decide.
That pattern is common in Lawrenceville because so many homes have ductwork running through unconditioned attics that sweat during the long humid season, pulling moisture into the return air. The furnace may be heating fine, but the attic duct leakage and oversized original tonnage are making the house feel muggy and uneven between rooms. In Russell Plantation, we ran a static pressure test on a 2003 Carrier 80% furnace with a cracked heat exchanger and found the ductwork in the unconditioned attic was sweating badly from oversized original tonnage. We quoted a right-sized 60k BTU replacement with a proper load calculation, and our crew swapped it before the first freeze, cutting short cycling and keeping the homeowner from paying for a condenser coil that was never the real problem. Call us at (478) 606-5046 if your house feels like that.
We repair boilers in Lawrenceville, especially in older homes near the square and in custom builds from the 1970s and 1980s. Boiler repair runs $150 to $700, covering zone valves, circulator pumps, expansion tanks, and pressure switches. We do not push boiler owners toward forced-air conversion unless the boiler is genuinely beyond saving. Call (478) 606-5046 and tell us what the system is doing, or not doing, and we’ll send a technician who works on hydronic heat every week.
