DeKalb County · ZIP 60115
When your DeKalb air conditioner reaches the point where repairs stop making sense, the next system deserves better than a rushed swap-out.
From houses near the NIU campus to newer construction around downtown DeKalb, DeKalb installs come with their own quirks: a university town's mix — historic neighborhoods, mid-century family stock, and a large rental inventory where reliable equipment and responsive service matter to owners and tenants alike.
We match the condenser and coil properly, set the equipment on a level pad, pull a deep vacuum on the line set, weigh in the charge, and verify the temperature split before we call it done.
Replacement usually enters the conversation for DeKalb homeowners when a few of these line up:
From quote to first cooling cycle, the process is simple:
We evaluate size, ductwork, electrical, and the pad location before quoting, so the quote is for a system that will actually perform in your home. That is the difference homeowners in DeKalb notice.
Good, better, best — real model numbers, real efficiency ratings, real prices, with financing options laid out if you want them.
We haul the old unit out, set the new condenser dead level, pressure-test and evacuate the line set the way the manufacturer requires, weigh the refrigerant charge in, and leave the electrical and drain work clean enough to photograph. Floors stay covered the entire day. It is the same standard we bring to every DeKalb visit.
The job is not done until the instruments say so: airflow, temperature split, and refrigerant readings all verified, warranty registered in your name, and a walkthrough of the thermostat and filter so you know your own system.
Sizing matters in DeKalb County more than most places: a system has to handle 95-degree humid afternoons without being so oversized that it short cycles through June and September. In DeKalb, a university town's mix — historic neighborhoods, mid-century family stock, and a large rental inventory where reliable equipment and responsive service matter to owners and tenants alike — and we size for the actual structure in front of us.
The classic missteps in AC replacement:
How replacement pricing really works:
The industry's dirty secret is the quote spread: the same equipment can be quoted thousands apart across companies, with the difference buried in installation quality — vacuum depth, charge accuracy, duct connections, commissioning. Our quotes itemize what you are getting, and the current specials ($175 off single units, $350 off full systems while they run) come off the written number, not off an inflated one. That is how we price work in the 60115 area — no exceptions.
Real customers, real Google reviews
“I got quotes from four different companies and ended up going with Apex. I really liked how quickly they communicated and that they were able to start the work the same day — Jojo explained what I needed, gave me different options, and was fully transparent with the pricing.”
“The Apex Climate Control technicians are simply the BEST!”
Good to know
Only the house can answer that — insulation, windows, orientation, and duct capacity all weigh in. The classic DeKalb County mistake is oversizing: the system blasts the thermostat down fast, shuts off before the humidity is handled, and the house feels like a cold basement all summer. It is one of the most common questions we get around DeKalb.
Through Enhancify: approvals start at a 550 credit score, qualified buyers can land 0% promotional terms, and the application takes minutes online before you commit to anything at all.
There is no honest one-number answer — home size, efficiency tier, duct condition, and electrical all move it — so we quote in person and in writing with options at more than one price. Right now the specials knock $175 off a single-unit swap and $350 off a full system, and financing reaches down to 550 credit scores.
If the furnace is also past the 12–15 year mark, usually yes — the indoor coil sits on the furnace, the blower drives the AC's airflow, and doing both at once saves duplicate labor. That is also where the $350 full-system special applies. If the furnace is young and healthy, we will say so.
We install proven equipment we can stand behind — Goodman is a staple on our trucks for its parts availability and warranty — and we service every major brand afterward regardless of who installed it.
A straightforward replacement is typically one day. If we are modifying ductwork, upgrading electrical, or installing a full system, we tell you up front if it runs longer. That has held true on every DeKalb job we have run.
Yes on both. Old condensers, coils, and refrigerant are removed and handled properly — nothing left at the curb.
One call reaches our local team — no national call center, no runaround. Serving DeKalb and all of DeKalb County.
