Most heating and cooling systems fail at the worst possible moment: the middle of a heat wave, the coldest morning of the year, the night before a tenant move-in. The failure rarely comes without warning. A system that is running longer than it used to, cycling on and off without reaching temperature, or producing uneven airflow through the house is telling you something before it quits entirely. Getting it looked at on a schedule, rather than waiting for the breakdown, is the difference between a repair call and an emergency.
We handle heating and cooling work across Gresham Park and the surrounding DeKalb County area. Whether the property is a single-family home running a furnace-and-AC setup or a smaller rental unit where the system has not been serviced in years, we scope the job on the call and confirm the price before anything is scheduled.

Scheduling a visit starts on the phone. When you call, describe what the system is doing and we confirm what the visit covers and what it costs before anything is booked. Most jobs can be scoped accurately from a description of the symptom, the equipment type, and roughly how old the system is. You do not need to wait for a technician to arrive before you know what you are paying for.
We take short-notice calls seriously. A property with no heat in January or no cooling in the middle of a Georgia summer is not a situation to put off, and we treat it that way. Emergency calls are handled within the same operating hours as everything else: 7 AM to 10 PM, every day.
For rental properties, a system failure affects someone's living conditions, not just a thermostat reading. For small commercial spaces, losing heating or cooling can mean closing the doors. We work around those constraints. The scope of the visit, the timing, and what is needed to restore comfort are all part of the conversation on the call. Your comfort is the whole job, and it gets treated that way.
The repair-versus-replacement question comes up on almost every call about an aging system, and the honest answer depends on specifics, not on a rule of thumb.
A repair makes sense when the fault is isolated, the rest of the equipment is in reasonable condition, and the cost of fixing it is clearly less than the cost of replacement over the next few years. A refrigerant leak at a single fitting, a failed capacitor, a worn contactor: these are repairs that extend the useful life of a system that still has years left in it.
Replacement becomes the better answer when the repair cost is a significant fraction of what new equipment would cost, when the system has needed multiple repairs in a short period, or when the equipment is running on a refrigerant type that is no longer widely available. An honest recommendation on repair versus replacement, never an upsell, is how that conversation goes. We explain the reasoning before any quote is given, and the decision is yours.
Ductless mini-split systems come up most often for spaces where running new ductwork is either impractical or not worth the cost. A converted garage, a room addition built after the original HVAC system was installed, a finished basement that the existing ducts do not reach: these are exactly the situations a mini-split is designed for.
The system consists of an outdoor unit and one or more indoor air handlers mounted in the space. There is no ductwork involved. Refrigerant lines run between the outdoor and indoor units, and each air handler can be controlled independently. That makes a mini-split useful for spaces with different occupancy patterns or comfort needs than the rest of the property.
Installing a mini-split involves sizing the unit to the space, positioning the indoor head correctly for airflow, running the refrigerant lines, and commissioning the system before the visit is complete. A service call on an existing ductless system covers the indoor air handler, the outdoor unit, the refrigerant circuit, and the condensate drain path. If a mini-split is not cooling or heating the way it should, or if a new installation is needed, call and describe the space and we will confirm what the job involves. The range of work covered is explained on the page listing our HVAC services.
A quote for a repair call and a quote for a full system replacement are arrived at differently, and we do not treat them the same way. What the fault turns out to be, how accessible the equipment is, whether parts need to be ordered, and whether a repair or a replacement is the better answer are the things that move the price. None of that gets glossed over.
For a repair call, the diagnostic determines the cause before any parts are quoted. For an installation or replacement, sizing the equipment to the property and checking whether the existing ductwork can support the new system are both part of what the quote covers. You get the rate on the call, before anything is scheduled, and the price covers what was discussed.
Call (678) 892-8789 and ask what the job involves.
A cracked or failing heat exchanger is a furnace problem that does not always produce obvious symptoms before it becomes a serious one. Carbon monoxide can enter the airstream from a compromised heat exchanger without any visible sign at the unit. An inspection of the heat exchanger is a standard part of a furnace service visit, and it is the kind of check that matters most on systems that have been running for several years without a maintenance visit. If a furnace in the property has not been looked at recently, this is a reason to schedule before the heating season starts.
Small commercial buildings in the area often run rooftop package units that handle both heating and cooling from a single piece of equipment mounted above the space. Service calls on rooftop units cover the same diagnostic points as a split system: refrigerant charge, coil condition, blower operation, controls, and airflow. The difference is access. A rooftop unit visit is scoped on the call so the technician arrives prepared for what the equipment requires.
Water collecting around the base of an air handler or furnace is not always a plumbing issue. A blocked condensate drain line, a cracked drain pan, or a frozen evaporator coil that has thawed are all HVAC causes that produce the same symptom. Cleaning the evaporator coil, clearing the drain line, and confirming the drain pan is intact are standard steps on a service call where water pooling is the presenting problem. Call and describe what you are seeing, and we will confirm what the visit covers.
A home or rental property that is cooling with window units or has never had a central air system installed is a candidate for a full central AC installation. The job involves selecting equipment sized to the property, integrating the new system with the existing furnace and air handler if one is in place, connecting the outdoor condenser, and confirming airflow through the ductwork before the installation is complete. Getting the sizing right matters more than the brand of equipment. An oversized unit short-cycles and handles humidity poorly. An undersized one runs constantly and never catches up.
We serve Gresham Park and the communities nearby throughout DeKalb County. That includes Panthersville, Candler-McAfee, Belvedere Park, Decatur, and Conley. Repair calls, seasonal maintenance, new installations, and emergency service are all available across this area for both residential and commercial properties.
If you are in one of these communities and are not sure whether the address falls within reach, call and ask. Most of the surrounding area is covered, and the call takes less time than wondering.
Yes. If you already have a service arrangement with us and want to add a property, call and we will confirm the scope and the scheduling. Adding a property works the same way as booking the first one.
The most useful information is the type of equipment you have, what it is doing or not doing, and roughly how old the system is. If the energy bill has changed noticeably, or if the problem started after a specific event like a power outage or a particularly hot stretch, mention that too. The more detail you can give on the call, the more accurately we can scope the job and confirm the price before the technician arrives.
We work on residential homes, rental units, and smaller commercial properties throughout the area. The scope varies by property type, but the process is the same: describe the system and the symptom on the call, get a quote, and schedule when it works. Both single-family homes and multi-unit rental properties are covered.
Yes. A system that has gone without a maintenance visit for an extended period is exactly the kind of call we take. The technician works through the equipment systematically to confirm what is in good condition and what needs attention, and the findings are explained before any repair is quoted. Older equipment that has not been serviced recently may have more than one issue, and the diagnostic accounts for that.
Yes. Whole-home air purifiers, UV air purifiers, and air filtration systems can be installed to work with the existing air handler and ductwork. The installation connects to the system so filtered air moves through every room when the blower runs. Call to confirm which options are compatible with your equipment.
A system that is due for maintenance before summer or before the first cold stretch of fall is a much easier call to make than an emergency call when the system has already failed. We are available every day from 7 AM to 10 PM for planned maintenance visits, repair calls, and installation quotes across Gresham Park and the surrounding DeKalb County area.

From a single repair call to a full system replacement, we handle the complete range of residential and commercial heating and cooling work across Gresham Park and DeKalb County. The table below lays out what each service covers, who it fits best, and a practical note to help you decide where to start. Call us with any questions and we will confirm the scope before anything is scheduled.
| System Service | Scope of Work | Best For | What to Keep in Mind |
|---|---|---|---|
| Heat Pump Installation |
| Homes replacing a furnace-and-AC setup or adding efficient heating and cooling in one unit | DeKalb County's mild winters make heat pumps a practical choice for year-round efficiency without the fuel cost of a gas furnace |
| Full System Installation & Replacement |
| Homeowners or property managers replacing aging equipment, systems requiring repeated repairs, or units running on discontinued refrigerant | Oversized equipment short-cycles and struggles with humidity control in Georgia's climate, so proper sizing is part of every replacement quote |
| Ductwork Repair & Sealing |
| Homes with rising energy bills, uneven temperatures, or systems that run longer than expected without reaching the set temperature | Leaking ducts push conditioned air into unconditioned spaces rather than into living areas, and the energy loss compounds over an entire cooling or heating season |
