Gresham Park is a working DeKalb County community where older homes and long-established neighborhoods define the character of the area. When the heat rolls in each summer, residents here do not have the option of waiting days for a repair appointment or dealing with vague pricing and missed commitments. Ace & A Heating and AC has spent 50 years building the kind of reputation that earns a callback, and we bring that same reliability to every service call in Gresham Park.
We show up prepared, give you straight answers, and price our work honestly with written estimates before anything gets started.
Much of Gresham Park’s housing was developed in the 1950s through 1970s, an era when homes were built with less insulation, fewer vapor barriers, and ductwork that has now been in service for decades. That translates to systems that face a higher baseline load and components that are often worn from years of steady use.
We are equipped to handle:
We service all brands, all ages of equipment, and all configurations.
Older systems in this climate tend to degrade gradually, which can make it hard to notice when something has crossed from normal wear into an actual problem. These signs are worth calling about:
None of these should be ignored, especially heading into the peak of summer.
Gresham Park is positioned in a part of DeKalb County where the terrain is relatively flat and open, which means afternoon heat builds with fewer natural breaks. Homes here also tend to have less tree shading on the south and west sides, which allows direct solar gain through windows and walls to drive interior temperatures up throughout the day.
Homes built in the 1950s and 1960s often have single-pane windows, minimal wall insulation, and original ductwork running through spaces that were never intended to carry conditioned air efficiently. That combination means the air conditioner is working against the building itself, not just the outdoor temperature. Understanding this dynamic changes how we approach a diagnostic and what solutions we recommend.
In early September, we got a call from Brenda, who had been managing with fans and portable coolers for about a week after her central AC stopped blowing cold. The system was running, the fan was moving air, but the output was barely cooler than the ambient temperature.
The technician found the refrigerant charge was severely low due to a slow leak at a fitting on the refrigerant line near the outdoor unit. The leak was repaired, the system was evacuated and properly recharged, and the coil was cleaned since the low charge had caused it to ice up and thaw repeatedly, leaving residue. Brenda’s home was back to comfortable by late afternoon. A week of discomfort that could have been avoided with a quicker call.
We are not interested in churning through service calls. We want to fix your system correctly, explain what we did, and make sure you feel good about the service when we leave. That is how we have operated since 1975, and it is reflected in our A+ BBB rating and the customers who call us back year after year.
When your AC needs attention, we are the team to call.
A refrigerant leak means the substance that allows your system to cool air is escaping the sealed system. Without the right refrigerant charge, the system cannot cool effectively and can sustain compressor damage over time. It should be repaired promptly by a certified technician.
We recommend against it. Running a system low on refrigerant can damage the compressor, which is the most expensive component in the system. Turning it off and calling for service right away usually protects you from a more costly repair.
Signs include the system running almost constantly, never reaching temperature on hot days, and high humidity indoors. A load calculation by a trained technician can confirm whether the equipment is properly matched to your home’s size and characteristics.
Not necessarily, but older homes often have duct systems, insulation levels, or building characteristics that affect which equipment performs best. We take those factors into account when assessing or recommending equipment.
A thermostat will not fix a mechanical problem, but a malfunctioning or outdated thermostat can cause erratic behavior like short-cycling, incorrect temperature readings, or failure to respond. If your system is behaving oddly, the thermostat is worth checking.
