AC Repair in Rockford, IL
Central air added to an older, furnace-first home brings its own quirks. Here’s what goes wrong and what a repair visit costs.
Serving Rockford and Winnebago County.
Why AC repair is different in Rockford’s older homes
Many Rockford homes started with a furnace-only forced-air system, or no ductwork at all. Central air came later, sometimes decades later, on ductwork sized for heating.
That mismatch causes predictable problems. Rooms cool unevenly. The system runs constantly without reaching the set temperature. The coil ices over because the original ducts restrict airflow too much for the cooling load.
Common AC problems in retrofitted systems
Undersized or leaky ductwork
Ductwork built for heating often can’t move enough air for cooling. You get uneven temperatures from room to room and a system that runs longer than it should.
Refrigerant leaks
A system that cools less over time, especially one that used to work fine, often has a slow refrigerant leak rather than a failing compressor.
Frozen evaporator coil
Usually caused by restricted airflow: a dirty filter, blocked vents, or ductwork that’s too small. It can look like a refrigerant problem, but it usually isn’t one.
Aging or mismatched equipment
A condenser added later and not matched to the original ductwork or the home’s cooling load tends to short-cycle and wear out faster.
What an AC repair visit costs in Rockford
Our service call is $100, the same as for furnace work. It covers the visit and finding the problem. You get the repair price before any work starts.
Refrigerant leak repairs and evaporator coil replacements cost more than a straightforward part swap, since the technician often has to locate the leak first.
Licensing: the same rule applies to AC work
Illinois issues no state-level HVAC license, for air conditioning or for furnaces. The credential that exists is the City of Rockford mechanical license, issued through the Rockford Mechanical Board and renewed annually. Ask for the license number before any AC repair begins.
AC not keeping up, or not running at all?

AC repair questions, answered
Why does my AC only cool some rooms?
In many older Rockford homes the ductwork was sized for heating only, then reused when central air went in. It often can’t move enough air to cool every room evenly.
Why does my AC unit have ice on it?
Most often it’s restricted airflow: a dirty filter, closed or blocked vents, or ductwork too small for the system. The symptoms can look like a refrigerant problem, so a technician should check airflow first.
How much does AC repair cost in Rockford?
Our service call is $100. Refrigerant leak repairs and coil replacements cost more than a simple part swap. You get the repair price before any work starts.
Is there a state HVAC license in Illinois?
