The short version
Twenty years on the tools
Two decades spent chasing down drips, odd noises and dead furnaces, so the usual suspects get checked first.
2-year labor warranty on new installs
Every new system we put in carries 2 years of labor coverage on the installation work.
Load math before equipment
Replacement capacity comes from the house and its ductwork, never just the old nameplate.
Weekends are workdays
Daytime visits happen on every day of the calendar, so a problem found on a weekend gets handled on the weekend.
Breakdown line after dark
When cooling or heat fails overnight, the emergency number still rings through to a person.
Pick the Problem, We Will Handle the Rest
Water on the floor. A condenser that will not settle into a steady run. A cold house in January. Most calls start with a symptom like that, and each one lands in one of these seven kinds of work.
AC Repair
Puddles by the air handler, a system that kicks on and off every few minutes, iced refrigerant lines or lukewarm vents. Clogged condensate lines, failing capacitors, worn contactors, tired fan motors and slow refrigerant leaks are the repairs that come up most.
AC Installation & Replacement
If the old unit keeps leaking money, the replacement is sized from a load calculation and the existing ducts, then set with a matched coil, sound line set, a fresh drain and safety switch, correct wiring, a permit where needed and a full startup test.
Heating & Furnace Repair
Burners that never catch, registers blowing cool, a furnace that fires and shuts down a minute later or a safety switch that keeps opening. Gas or electric, it gets worked through component by component. A gas smell comes first: get everyone outside and ring the gas utility or 911.
Heat Pump Services
One outdoor unit doing both jobs, so trouble shows up in both seasons. Stubborn ice, a reversing valve stuck in one mode, strip heat that runs all day and dual-fuel controls that switch at the wrong time, plus full replacements and new installs.
HVAC Maintenance
Before summer, a cooling visit; before winter, a heating one. Drains flushed, coils cleaned, capacitors and contactors tested, refrigerant and airflow measured, burners and safeties checked and the results written out in a short report.
Emergency HVAC Repair
An air conditioner dead in sweltering weather, a furnace out when it is near freezing, water spreading across a ceiling or a hot electrical smell. Call the emergency line at any hour and get the safe first steps before help arrives.
Commercial HVAC
Restaurants, small offices, retail suites, places of worship, clinics and light industrial shops along the corridor. Packaged rooftop equipment, commercial splits and buildings with several zones, with service fitted around opening hours and replacements planned well ahead.
How a Doraville Service Call Unfolds
You explain the trouble
Where the water is showing up, how often the system starts and stops, any new sound or smell, and roughly how old the equipment is. A clogged filter or a tripped float switch can sometimes be sorted out right on the phone.
A technician finds the source
Drain line, float switch, coil, refrigerant charge, capacitor, contactor, thermostat wiring. Each one is checked and measured until the reason for the leak or the cycling is clear.
You get the fix and the price
What failed, what it takes to correct it and what it costs, all before a wrench turns. If the system is old enough that a new one deserves thought, you hear both options side by side.
Repair, test, done
The work gets done neatly, then the system runs long enough to prove the drain carries water away, the cycles are normal and every safety control responds. You get a quick rundown before the technician leaves.
Why People Keep This Number in Their Phone
Three habits shape every job, from a one-bedroom condo to a rooftop unit over a busy dining room.
Equipment sized to the building
An oversized air conditioner is one of the most common causes of short cycling and clammy rooms. Before any new system is recommended, the house or suite gets a load calculation and the ductwork gets a hard look, so the new unit runs long, steady cycles instead of quick bursts.
Homes and businesses, one crew
The same technicians handle a split system in a family home and a packaged unit on a commercial roof. Landlords, property managers and business owners who also own a house can keep a single number for all of it.
Open seven days
Leaks and breakdowns ignore the calendar, so daytime appointments run every day, weekends included. That means a drip found on a weekend morning can be traced the same weekend instead of soaking the ceiling until the work week starts.
Doraville and the Neighboring Towns We Serve
Doraville sits in the northeast corner of DeKalb County, where Buford Highway, Peachtree Industrial Boulevard and I-285 all run close together. The housing is a real mix: brick ranch homes on older streets, townhomes, apartment buildings and newer construction near the redeveloped industrial land, plus a long line of restaurants, shops and offices along the corridor. Older homes often carry ductwork that was sized for very different equipment, and commercial kitchens put a heavy load on rooftop units through the long humid summer. Service reaches Doraville and the surrounding towns of Chamblee, Brookhaven, Norcross, Tucker, Dunwoody, Peachtree Corners, Sandy Springs, Decatur, Lilburn and Duluth.
Older homes, newer equipment
Ductwork from decades ago and a modern high-efficiency system do not always get along. Sizing and airflow get checked so the new unit does not short cycle on day one.
Kitchens and dining rooms
Restaurants and food businesses along the corridor run their rooftop units hard. Drains, belts and coils get extra attention there.

A dripping system usually means a clogged condensate line, a cracked pan or a coil that is icing and melting. Left alone it can stain ceilings and soak insulation. Shut the cooling off, put a towel down and phone. A technician can usually tell you what to check while you wait.

Straight Answers for Doraville Homeowners and Owners
Six questions that come up on almost every replacement or repair call.
Does new equipment have to be registered to keep the manufacturer coverage?
Usually, yes. Most manufacturers ask owners to register new equipment within a set window after installation, and missing that step can shorten the parts coverage. Keep the model and serial numbers and the install date handy, and ask the technician to walk you through registration when the system goes in.
What does a SEER2 rating tell me, and does paying for a bigger one make sense?
SEER2 rates the cooling output you get per unit of electricity across a typical season, measured under the newer federal test conditions. A higher rating can trim operating costs, but only if the system is sized correctly and the ductwork and installation are sound. A well-matched, carefully installed system with a moderate rating often outperforms a high-rated one that was guessed at.
Will replacing my system bring my power bill down?
It can, but no honest technician can promise how much. Bills depend on the old system's condition, the new system's efficiency, the size match, the ducts, your thermostat habits and the weather. What a correctly sized replacement does reliably deliver is steadier temperatures and better humidity control, and those are worth weighing alongside any savings.
My air conditioner is dripping water indoors. What causes that?
The most common cause is a clogged condensate drain line, which backs water into the pan until it spills over. A cracked drain pan, a failed condensate pump, a disconnected drain fitting or a frozen coil that later melts can do the same. Turn the cooling off to stop more water, then have the drain, pan and coil checked so the real cause gets fixed.
Do you take care of both houses and commercial buildings?
Yes. The same team services split systems, furnaces and heat pumps in homes, and handles packaged rooftop equipment, commercial condensers and buildings with several zones for offices, restaurants, retail spaces, churches and light industrial users. Landlords and property managers can use one number for every property.
What coverage comes with a new system, and what about a repair?
There are usually separate pieces: the manufacturer's parts coverage on new equipment, which often depends on registration, and the installer's coverage on labor and repair work. Terms differ by equipment and job, so the coverage that applies to your work is explained before anything is agreed.
Fix the Cause and the Symptom Goes Away
HVAC Doraville works on a simple idea. A leak is a drain problem, a pan problem or a coil problem, not just a wet floor. Short cycling is a sizing, airflow, refrigerant or control problem, not just an annoying noise. Find which one it is, fix that and explain it so the owner understands what happened. Houses, rentals and commercial buildings all get handled that way.
