HVAC Company in Lawrenceville, GA

Dalton Heating & Air handles heating and cooling work across Lawrenceville with written pricing, a one-year repair guarantee, and crews that show up inside the stated window. Lawrenceville’s mix of 1980s and 1990s subdivisions, older intown homes near the square, and newer construction off Sugarloaf Parkway means no two calls are alike. Add Georgia summer humidity and February temperature swings, and you get systems that age in specific, predictable ways. Call (361) 306-9515 when a system quits, starts making noise, or stops keeping set temperature.

Why Lawrenceville Homes Are Different

The biggest factor in Lawrenceville is age spread. Homes built along Five Forks Trickum Road and around the historic courthouse square often run original ductwork that was sized for less insulation than most attics have now. Homes in newer sections near Collins Hill and the Sugarloaf corridor tend to have tighter building envelopes, which changes how we size heat pumps and how often systems short-cycle in mild weather.

Humidity is the second factor. Lawrenceville sits at a low elevation with heavy tree cover in older neighborhoods, so indoor coils and drain pans work harder in summer than the same equipment does across the river in drier counties. We regularly find condensate lines backing up in August in homes around Lawrenceville Highway simply because the system never gets a break. Furnaces get their own stress in winter; houses built before 1995 in Lawrenceville often have 80 percent efficiency units working against under-insulated crawl spaces.

Gwinnett County permits apply to equipment change-outs, and several Lawrenceville HOAs require units to be screened from street view. We handle the paperwork as part of installation, but it changes scheduling. If your neighborhood has an architectural review committee, plan for a couple of extra days before the new system goes in.

Our Main Lawrenceville Services

Most calls in Lawrenceville come down to two things: an air conditioner that stopped cooling in July, or a furnace that will not fire in January. Each service has its own Lawrenceville page with pricing and same-day detail.

AC Repair in Lawrenceville

Most Lawrenceville AC failures we see between June and September are either a failed capacitor, a clogged drain line, or low refrigerant from a slow leak in the evaporator coil. Systems in homes along Grayson Highway and Webb Gin House Road tend to run longer hours because of west-facing exposure and high tree humidity, which accelerates wear on contactors and fans. We arrive with common parts on the truck, diagnose on the spot, and put the repair price in writing before a single screw comes out. The full breakdown, including cost ranges and what we stock, is on AC Repair in Lawrenceville.

Heat Pump Installation in Lawrenceville

Lawrenceville sits in a climate band where heat pumps make real sense for a lot of houses: winters rarely stay below freezing for long, and summers demand efficient cooling. Newer construction off Sugarloaf Parkway often has dual-zone systems from the start, but older homes near the square may be converting from a straight AC plus gas furnace setup. Sizing matters here; Gwinnett’s humidity means an oversized heat pump will cool the air fast and leave the house clammy. The process, the load calculation, and the full installed price are on Heat Pump Installation in Lawrenceville.

Furnace Repair in Lawrenceville

Cold snaps in Lawrenceville come fast and usually at night, which is when we get the most no-heat calls from subdivisions along Cruse Road and around Tribble Mill Park. Common culprits are flame sensors that will not prove the burner, failing igniters, and blower motors caked with dust from homes with pets or recent drywall work. A furnace that trips its limit switch is not something to keep resetting. We show up with the repair guarantee in writing and the parts to fix most units the same day. Details, including what each common repair costs in Lawrenceville, are on Furnace Repair in Lawrenceville.

Pricing for HVAC Company in Lawrenceville, GA

Service Typical range in Lawrenceville
AC repair (minor electrical or capacitor) $150 – $300
AC repair (blower motor, contactor, or circuit board) $300 – $650
Furnace repair (flame sensor, igniter, or thermostat) $150 – $350
Furnace repair (gas valve, blower motor, or control board) $350 – $700
AC installation (full system replacement) $3,500 – $7,500
Tune-up (cooling or heating seasonal check) $80 – $200

What pushes a Lawrenceville repair toward the top of the range is usually access: attic units in older homes near the square get hot fast, and crawl-space furnaces in the county’s clay-heavy soil mean an hour of work before we even touch the system. Every price is written before work starts. That is a Garrison Standard rule, not an upgrade.
