A new air conditioner should be a 15-year decision, not a summer band-aid. We install cooling systems across Lemont that are sized to the actual house, not to a rule of thumb.
We are a North Aurora company, about 48 minutes from our North Aurora shop, and we have replaced systems all over Lemont — limestone-era historic homes downtown with upscale newer construction on the surrounding ridges — retrofit challenges and modern multi-zone systems in the same service day.
Every quote starts with the house itself — square footage, insulation, windows, duct condition, and how the current system has actually performed — because an oversized unit short cycles and an undersized one never catches up in July.
We recommend getting replacement numbers when you see this pattern:
Here is how an Apex install day goes:
The quote starts with a walk through your actual home — measuring the load, checking duct capacity and electrical, scoping the pad location — because equipment picked off a square-footage chart is how houses end up clammy in July.
Good, better, best — real model numbers, real efficiency ratings, real prices, with financing options laid out if you want them. That is the difference homeowners in Lemont notice.
Old equipment hauled away, new condenser set level, line set pressure-tested and evacuated properly, charge weighed in, drain and electrical done right. Floors protected the whole time.
We verify airflow, temperature split, and refrigerant readings, register the warranty, and walk you through the thermostat and filter before we leave. It is the same standard we bring to every Lemont visit.
What a new AC actually costs in Lemont — honestly:
Financing changes what is realistic: through Enhancify, approvals start at a 550 credit score with promotional terms including 0% options for qualified buyers, so a dead AC in a heat wave does not force the worst-value decision. Apply before we visit if you want the numbers ready — the link is on our financing page. The written quote is the promise — in Lemont and everywhere else we work.
A lot of Lemont air conditioners went in during the same construction wave, which means a lot of them are aging out together. If yours is one of them, replacing on your schedule beats replacing during the first 95-degree emergency of the year.
What to avoid when buying a new AC:
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
Stepping up from a tired 8–10 SEER unit to modern equipment cuts real money off cooling season — but only if the install delivers the rating. Charge, airflow, and duct sealing decide that, which is why our commissioning is done with gauges, not glances. We are about 48 minutes from our North Aurora shop, so help is close.
Only the house can answer that — insulation, windows, orientation, and duct capacity all weigh in. The classic Cook 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. Either way, you will get a straight answer from us.
We offer financing through Enhancify with approvals for credit scores as low as 550 and 0% options for qualified customers. You can apply online before we even visit.
It depends on the size of the home, the efficiency tier you choose, and the condition of the existing ductwork and electrical, which is why we quote in person. We give you options at multiple price points in writing, and current specials take $175 off a single-unit install or $350 off a full system.
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.
Most straight replacements wrap in a single day. When ductwork changes, electrical upgrades, or a paired furnace enter the picture, the timeline stretches — and we tell you that at the quote, not on install morning.
One call reaches our local team — no national call center, no runaround. Serving Lemont and all of Cook County.
