What Size and Type of AC Fits a Buffalo Grove Home?
In Buffalo Grove, a new AC has to match very different houses. Slab ranches often have the furnace and coil in a closet with limited return air, so we check airflow before choosing tonnage. Two-story homes in subdivisions like Strathmore and the Woodlands of Fiore tend to run warm upstairs, and a two-stage condenser paired with a variable-speed furnace blower runs longer at low speed to pull more humidity and even out the floors. Some homes still have R-22 systems, which means a new condenser and matched coil, plus a check of whether the line set can be reused. Townhome associations may also have rules on where the condenser can sit.
Our Buffalo Grove AC Replacement Process
First, a free estimate: we measure your Buffalo Grove home, look at the ductwork and electrical, and run a load calculation so the AC is sized to the house. You get written options and prices. Install day takes one day for most homes. We recover the old refrigerant, set the new condenser and coil, braze the lines under a nitrogen purge, evacuate to 500 microns and charge by superheat and subcooling. Before we leave, we test airflow and register your warranty.
Repair vs. Replace for Buffalo Grove Air Conditioners
Air conditioners in the Chicago area typically last 12 to 17 years. If yours is near that age and the compressor or coil has failed, a new AC is usually the smarter buy. R-22 systems are expensive to recharge, so they lean toward replacement too. A newer unit with a bad capacitor or fan motor is almost always worth repairing.

Buffalo Grove AC Replacement FAQs
Is a new AC in Buffalo Grove expensive?
A new air conditioner with its matching coil costs $5,000 to $9,000 installed. We show ComEd rebates for qualifying heat pumps and financing options on the written quote. Closet coil swaps in slab ranches, upstairs airflow in two-story homes and association rules on condenser placement drive most of the price.
How fast can I get an AC replacement estimate in Buffalo Grove?
Call or book online, and we will schedule a free visit at a time that works for you, then measure your Buffalo Grove home and give you written options.
Is the permit included in your AC quote?
Where Buffalo Grove requires one, the permit and inspection scheduling are part of the job. We confirm the requirements before install day.
What is the difference between single-stage and variable-speed AC?
Single-stage runs at full power or off. Two-stage and variable-speed systems run at lower speeds most of the time, so rooms stay more even and the house feels less sticky.
How soon can you install a new AC?
We schedule the install as soon as the calendar allows after you choose a system. The install itself usually takes one day.
Do you use subcontractors for AC installs in Buffalo Grove?
No. Our own NATE-certified crews install every system, and we are about 30 minutes from Buffalo Grove.
Do I need a new furnace when I replace my AC?
Not always. If the furnace is much newer, we can replace only the AC and match the coil to it. If both are 15 or more years old, doing both is usually smarter.
