Dunwoody generates a steady mix of HVAC work: homes that have been running the same system for a decade or more, newer construction where the equipment is right but the controls have never been set up correctly, and small commercial properties where a rooftop unit going down costs more than just the repair. Some customers call once, get the problem fixed, and that is the end of it. Others want somebody who knows the system to come back each season and keep it running well. We handle both, and the process starts the same way either time: a clear conversation about what is happening and a price confirmed before anything is scheduled.
We cover the full range of residential and commercial heating and cooling work in Dunwoody and the surrounding area. Repairs, full system replacements, heat pump installations, ductwork, thermostats, indoor air quality, and seasonal maintenance all come through the same number.

Whatever the job involves, you get a straight answer on the call.
A system that gets looked at before it fails costs less to operate than one that runs until something breaks. That is not a general statement. It is what comes out of a seasonal tune-up: a technician goes through refrigerant levels, coil condition, blower performance, drain line, and thermostat calibration, and anything that is wearing early gets caught before it becomes a no-heat or no-cooling call. The HVAC work done properly, start to finish, means the visit ends with the system confirmed ready for the season ahead, not with a list of things to watch.
A spring AC tune-up and a fall heating check are the two visits that keep a system from becoming a problem. The spring visit covers the cooling side: refrigerant charge, evaporator and condenser coils, airflow through the supply and return, and the controls that manage the cycle. The fall visit covers the heating side: ignition, heat exchanger, blower motor, and thermostat response. Scheduling both means the system is ready before it is needed most, not after it has already run into trouble.
A tune-up that finds the equipment in good shape but the home still uncomfortable often points to the duct system. Leaking or poorly sealed ducts lose conditioned air before it reaches the rooms it is meant to serve, and the result is uneven temperatures and a system that runs longer than it should. Duct inspection and sealing are part of what we offer alongside the equipment work. For homes where filtration or humidity is the concern, whole-home air filtration and humidifier or dehumidifier installation address what the HVAC system circulates, not just how it heats or cools. The region's humid summers make whole-home dehumidification a practical upgrade rather than an optional one.
The sooner you call, the sooner your comfort is back, and that applies whether the call is from a homeowner, a property manager with a tenant in the unit, or a business that cannot shut down for the day. When a system fails completely, the job gets scoped on the phone: what the equipment is doing, what type of system it is, and what the visit will involve. A price is confirmed before anything is scheduled, and that conversation happens before anyone comes out.
For properties where access or timing is a constraint, that is worth raising on the call. A tenant who works from home, a business that has to stay open, or a rental property where the owner is not on site are all situations we work around. The scope and the rate are settled on the phone, and the visit is arranged around what the property actually needs.
Emergency calls for no heat and no cooling are handled the same way as routine ones.
Call (470) 995-4495 and describe what the system is doing.
The situation gets scoped, a price is confirmed, and the visit is booked.
Work that was started by someone else and left incomplete, or a repair that held for a few weeks and then failed again, is a situation we see. The visit covers what the system is doing now, not what the last technician said it needed. Refrigerant, airflow, and controls are all checked before a verdict, so the diagnosis is based on what is actually happening rather than on what was already tried.
If another contractor has told you the system needs to be replaced, a second opinion is a reasonable thing to ask for before committing to that cost. The visit looks at what the equipment is actually doing, whether the fault is in a component that can be repaired or whether the system has genuinely reached the end of its useful life, and what a replacement would involve if that is the right answer. That conversation happens on the call and continues when the technician is on site.
The price is confirmed before anything is scheduled. When you call, the job gets scoped on the phone: what the system is doing, what type of equipment is involved, and whether the situation calls for a repair visit or a full replacement estimate. That gives you a rate that covers what the visit involves before anyone comes out.
What moves a quote is what the job actually turns out to require. A repair that looks straightforward from the symptom description can involve additional worn components once the system is open, and that conversation happens before any additional work goes ahead. Equipment type, system age, whether parts have to be sourced, and the extent of the work all factor into the final figure. A replacement quote involves a load calculation to size the new equipment correctly, and that is part of what the visit covers.
The symptoms you describe on the phone shape what gets brought out, so the more clearly you can describe what the system is doing, the more useful the scoping conversation will be. What the work involves is covered on our heating and cooling services page.
Call (470) 995-4495 and ask what the rate covers. You get a straight answer before anything is booked.
A heat pump that stops heating in cold weather, ices over on the outdoor coil, or runs in defrost mode more than it should is a common fault in the region. The visit covers the reversing valve, refrigerant charge, defrost controls, and airflow across the outdoor coil. Defrost faults are frequently misdiagnosed as refrigerant problems, so the full check matters before any parts are quoted.
A system that runs for long stretches without reaching the thermostat's set point is usually pointing to one of a few things: a refrigerant issue, a dirty coil, a duct leak pulling in unconditioned air, or equipment that was never sized correctly for the space. The visit works through each of those in sequence rather than replacing a component on assumption.
A system that turns on, runs briefly, and shuts off before the space reaches temperature is short cycling, and the cause matters because the fix varies. Oversized equipment, a refrigerant fault, a failing compressor, or a control board issue can all produce the same symptom from the outside. The diagnosis covers each of those before any repair is quoted.
An AC that is running but not cooling is one of the more common calls in a humid summer climate. Low refrigerant charge, a dirty or iced evaporator coil, and a failing compressor are the main causes, and they are not always easy to distinguish from the symptom alone. The visit covers refrigerant level, coil condition, and compressor operation before a verdict is given.
For homes in Dunwoody that are replacing an older gas furnace and AC combination, a heat pump handles both heating and cooling from a single system and performs efficiently through the region's mild-to-moderate winters. For additions or spaces that existing ductwork does not reach well, a ductless mini-split is a strong fit. Installation covers sizing the unit for the space, connecting the air handler, and confirming thermostat and smart-control compatibility.
Small commercial properties in Dunwoody often run packaged rooftop units rather than split systems, and the service and repair work is different from residential equipment. Commercial rooftop units are covered as well as residential, and the same scoping process applies: the job is described on the call, the rate is confirmed, and the visit is booked.
We serve Dunwoody and the communities around it in DeKalb County and the broader north Atlanta area. Neighboring cities and towns we cover include Sandy Springs, Doraville, Chamblee, Peachtree Corners, and Brookhaven. If your address is outside Dunwoody proper, call and we will confirm coverage before anything is scheduled.
All calls are answered every day from 7:30 AM to 9:00 PM. Residential homes, rental properties, and commercial buildings across the area are all covered under the same number.
Yes, and that is one of the main reasons a mini-split is the right fit for those situations. The indoor unit mounts on a wall or ceiling and connects to the outdoor unit through a small penetration in the wall, with no duct run required. It is a common solution for additions, detached spaces, and older homes where adding ductwork would be disruptive or impractical.
It can, and when it does, that conversation happens before any additional work goes ahead. If a repair that looked straightforward from the symptom description turns out to involve a worn component that was not visible until the system was open, you are told what it is and what it would cost to address before anything is done. Nothing is added to the scope without a confirmed price first.
The visit gets arranged around the property's situation, and that is worth raising on the call when the job is scoped. A tenant who needs to stay in the unit, a property the owner is not present at, or a business that has to stay open during the work are all situations we work around. The scope and the rate are settled before the visit is booked, so there are no open questions when the technician arrives.
The rate is confirmed on the call before anything is scheduled, and that applies regardless of where in the area the property is.
If there is any question about whether an address falls within the service area, calling (470) 995-4495 is the fastest way to confirm.
That depends on the scope of the work and where the equipment is located. A rooftop unit replacement may have minimal impact on the interior. Work that involves the air handler inside the building or duct modifications in occupied areas may require more coordination. Mention the business's operating situation when the job is booked and we will confirm what the work involves and how to plan around it.
A repair visit covers what the system is doing, diagnoses the fault, and quotes the fix. A replacement assessment goes further: it includes a load calculation to confirm the right equipment size for the space, a review of what the existing ductwork and controls can accommodate, and a price for the new system before anything is ordered. If a repair visit finds that the equipment is past the point where repair makes sense, that conversation happens on site before any decision is made.
The most common thing is describing the symptom in terms of what they think the cause is rather than what the system is actually doing. Saying the refrigerant is low when the system is blowing warm air, or that the compressor is bad when the system is short-cycling, can lead the conversation in the wrong direction. Describing what the system does and does not do, what sounds it makes, and when the problem started gives the most useful starting point.
A sharp increase in running cost without a change in how the home is being used usually points to a drop in system efficiency. Common causes include a dirty evaporator or condenser coil, low refrigerant charge, a failing compressor drawing excess current, or duct leaks that are making the system run longer to reach the set point. A service visit that checks those components gives a clearer picture of where the inefficiency is coming from.
Not the biggest name in town. Just the one that answers. No runaround.
