That’s why we send trained, background-checked techs who understand the specific pain points of Georgia heat and 100-year-old ductwork.

Why Cold Harbour Heating and Air Marietta Is Roswell’s Preferred AC Repair Company
Cold Harbour Heating and Air has been fixing air conditioners in Roswell long enough to know exactly what our technicians will find when they show up. The city’s mix of pre-1900 homes near the Chattahoochee and 1990s subdivisions near Crabapple presents two very different diagnostic challenges. We’ve serviced original R-22 systems in three-story brick homes along Mimosa Boulevard and handled failed capacitors in slab-foundation ranches off Holcomb Bridge within the same week.
What holds it together is the written guarantee we hand you before we leave. Every repair gets covered by the 365-Day Done Right Promise: if your AC fails again within a year, we come back and fix it at no charge. Victor Mancini, who leads our team, made that promise a condition of every job we take, not an optional add-on. Local dispatch is coordinated from our Atlanta area office, and crews serving Roswell carry parts for Trane, Lennox, Goodman, Rheem, and other major brands on their trucks.

AC Recharge in Roswell
An AC Recharge in Roswell involves topping off the refrigerant your system needs to pull heat out of your home, and it commonly runs $150 to $650 depending on the refrigerant type and leak severity. Homes in Roswell’s older neighborhoods frequently run R-22, a refrigerant no longer manufactured in the U.S., which makes every pound expensive. In many 1990s era subdivisions around East Cobb and Woodstock Road, we see systems that lose a pound or two each season, and a recharge is the right short-term fix while you plan replacement.
When Roswell Homes Need a Recharge
A system blowing warm air, ice forming on the copper line outside, or an outdoor unit running constantly without cooling are the telltale signs we look for in Roswell homes. The humid subtropical climate here means your compressor works harder from May through September than it would in a drier region, which accelerates refrigerant loss in aging coils.
Refrigerant Types in Roswell’s Housing Stock
If your home was built before 2010, it likely runs R-22, which now costs three to five times what R-410A does per pound. We measure both types with gauges, find the leak, and give you a written price for recharge plus leak repair before any tool comes out.
Emergency AC Repair in Roswell
Emergency AC Repair in Roswell covers situations where your system fails during a 95°F afternoon and you cannot wait two days for a regular appointment, with most emergency repairs falling inside the same $150 to $650 range. We answer the phone with a live person 24 hours a day, every day, so a Roswell homeowner whose upstairs bedroom hits 88°F at 11 p.m. talks to someone who can dispatch a technician. Our trucks carry capacitors, fan motors, contactors, and refrigerant for same-day work.
What Counts as an Emergency
Complete system failure during extreme heat, a burning smell from the air handler, or water leaking through a ceiling are the calls we treat as true emergencies in Roswell. We prioritize those over routine tune-ups because the health risk is real, especially for older residents and homes with young children.
Same-Night Repairs in Roswell Neighborhoods
If you live in Martin’s Landing, Brookfield, or along Riverside Road, our technicians can typically reach your door within a few hours of your call, even during summer weekends. We carry the parts that fail most often on Georgia systems: dual-run capacitors, condenser fan motors, and contactors.
Trusted Brands We Service in Roswell
Our technicians hold training on nine major residential brands, including Trane, Lennox, Goodman, and Rheem, so the system already in your Roswell home gets serviced rather than condemned. We keep common OEM and aftermarket parts for Lennox and Goodman systems in our local trucks, which speeds up repairs in neighborhoods like Saddlebrook and Heatherwood. If you have a 2012 Rheem that trips its breaker or a 2007 Trane that blows warm, the technician who shows up will recognize it. We diagnose the failure, not the brand, and we do not push replacement when a repair makes sense.

AfterCommon AC Repair Problems We See in Roswell Homes
- Frozen evaporator coils from undersized or leaky ductwork. Many older Roswell homes, especially in the historic district, have ducts sized for a coal furnace from the 1920s, not a modern 3-ton AC. The restricted airflow drops coil temperature below freezing on humid afternoons, and we spend a lot of June days thawing coils and resealing duct joints.
- R-22 systems with slow leaks that get topped off year after year. A 1998 Goodman off Hardscrabble Road might cool fine for three weeks after a recharge, then slowly lose its charge again. Refrigerant that’s no longer manufactured costs more every season, and at some point the honest answer is stop paying for a dying system.
- Clogged condenser coils from pine needles and pollen. Roswell’s tree canopy is beautiful and relentless. Pine needles, sweetgum balls, and spring pollen pack into the outdoor unit’s fins, raising head pressure until the high-limit switch trips. We clean coils on nearly every call to homes near the Chattahoochee River.
- Capacitor failures during heat waves. A capacitor gives your compressor and fan motor the starting jolt they need. Roswell’s long cooling season plus voltage spikes during summer thunderstorms takes out capacitors frequently, and the symptom is often an outdoor unit that hums but won’t start.

FAQs About AC Repair in Roswell
Because your home’s original ductwork was sized for a coal or wood furnace, not modern air conditioning, and single-zone systems treat the whole house as one temperature. The fix in a Roswell historic home often means a Manual J load calculation, duct sealing or resizing, and sometimes a zoned damper system rather than simply swapping the condenser. We’ve corrected this in homes along Canton Street and the surrounding streets without disturbing original plaster, and the difference is measurable within a day. Call (762) 240-5599 for a diagnostic visit.
Repairing a 30-year-old R-22 system in Roswell only makes sense if the failure is minor and the system is otherwise sound; otherwise, the cost of discontinued refrigerant makes replacement the better long-term decision. We’ll give you a straightforward assessment: what’s wrong, what the repair costs, and what a new system costs, all in writing before any work starts. The choice stays yours, but we’ll tell you honestly when you’re putting money into a system that’s near the end.
Many 1980s Roswell homes have 100-amp or even 60-amp panels, and a modern high-efficiency AC with a variable-speed blower often needs more capacity than the old panel can safely provide. We inspect the panel and the service entrance as part of every installation estimate. If an upgrade is required, we’ll tell you before you spend a dollar on equipment.
Because pine needles, pollen, and debris clog the condenser fins and drive up head pressure until the high-limit switch trips as a safety measure. In heavily canopied Roswell neighborhoods, regular coil cleaning is not optional maintenance, it’s required to keep the system running through August. Our technicians include a coil inspection with every repair call.
Yes, and we specialize in it. For homes in the Roswell Historic District, we cut access panels only where absolutely necessary, use small-diameter tools, and plan our work around original trim, baseboards, and plaster. We treat every historic home as if it were our own, and the last thing we want to do is put a hole in a wall that’s stood for a century. Call (762) 240-5599 to talk through your home’s situation.
