Romeoville is a fast-growing community in Will County, and with that growth has come a lot of homes built during the 1980s, 1990s, and 2000s — many of which are now running original or aging cooling equipment through Illinois summers that push heat indexes well above 100 degrees. When a system that has been working hard for decades finally gives out, it rarely chooses a convenient moment to do it.
Andersen Plumbing, Heating and AC Repair has been serving communities throughout the Fox Valley and Will County since 1985. Our licensed technicians show up prepared, quote the repair before touching anything, and work to get your home comfortable again in a single visit whenever possible. We are available around the clock because AC problems do not wait for business hours.
Romeoville’s housing landscape is a story of two eras. Subdivisions built in the late 1980s and early 1990s near the Route 53 corridor are now home to equipment that is approaching or past its designed service life. Meanwhile, newer developments toward the Interstate 55 corridor have systems that are younger but often pushed hard by larger open floor plans and two-story layouts that demand more from cooling equipment.
We service the full range of problems both types of homes produce. Our technicians handle refrigerant leak diagnosis and recharge, capacitor and contactor replacement, compressor diagnostics, condenser and evaporator coil cleaning, blower motor repair, and drain line clearing. We also diagnose thermostat and control board failures that cause systems to behave erratically — running when they should not, or not running when they should. If your system is short-cycling, freezing up, leaking water, or simply cannot hold a set temperature, we will find the cause and walk you through the fix before any work begins.
We work on all brands and system configurations, including central air, heat pumps, and ductless systems.
Romeoville summers are long and humid, and a system that is starting to fail will usually show warning signs before it quits entirely. Here is what to watch for.
Catching these early usually means a simpler repair. Our team is available any time of day or night — call us when you first notice something is off.
Will County’s flat terrain and summer weather patterns create sustained high-humidity conditions that accelerate wear on cooling equipment. Romeoville sits between two major highways and a network of retention ponds and drainage channels, and that combination keeps ground-level humidity elevated through the hottest months of the year.
The most common issue we find in Romeoville homes is capacitor failure. Capacitors are the components that help motors start and run, and they degrade faster in systems that run long cycles through humid summers. A weak capacitor often causes the system to struggle to start or to draw more power than it should, which then puts strain on the compressor. Left alone, a bad capacitor can eventually take the compressor with it — a far more expensive fix.
Condenser coil fouling is another pattern we see often. The retention ponds and drainage areas common in Romeoville subdivisions contribute to elevated airborne debris and cottonwood during late spring, and outdoor units that are not cleaned regularly lose the ability to shed heat efficiently. We also respond to a fair number of drain line backups in this area — Romeoville’s clay-heavy soil means finished basements are common, and a clogged condensate line that overflows into a finished lower level can cause significant water damage quickly.
Greg called us on a Saturday morning after his family had spent a miserable Friday night in their Lakewood Falls home with no working air conditioning. The thermostat was set to 72, but the house had climbed to 81 by bedtime and kept going.
Our technician arrived that morning and ran through a full system check. The outdoor unit was running, but the compressor was drawing significantly more current than it should. The run capacitor had failed, and the compressor had been struggling to start properly for some time — long enough that it had developed a hard-start condition. The tech replaced the capacitor and installed a hard-start kit to reduce strain on the compressor at startup. The system came back online, the refrigerant charge tested within range, and the house was cooling properly within the hour. Greg mentioned he had heard a faint clicking sound from the outdoor unit for a few weeks before everything stopped. That clicking was the capacitor going. A service call at the first sign would have been a quicker fix — but we got them squared away before the weekend was lost entirely.
Romeoville homeowners have options when it comes to HVAC contractors. Here is why so many families in Will County have trusted Andersen for decades.
Call us. We are available 24 hours a day, seven days a week, and we treat after-hours calls the same way we treat daytime ones — with a licensed technician dispatched to your home as quickly as possible. Do not wait until morning if the heat is becoming unsafe for your family.
This usually points to one of a few things: low refrigerant from a slow leak, a restricted condenser coil that cannot release heat properly, or a failing compressor that is running but not pumping refrigerant effectively. A technician will be able to pinpoint the cause quickly with a diagnostic check.
Once a year before the cooling season starts is the general recommendation. A pre-season tune-up catches small issues before they become failures during the hottest stretch of summer. Our $129 Membership Plan includes maintenance visits that take care of this for you on a regular schedule.
In most cases, yes. We work on all major brands and system ages. The main consideration with older systems is whether parts are still available and whether the cost of repair makes sense relative to the system’s remaining useful life. We will give you an honest read on both before recommending a course of action.
It does. Air conditioners remove both heat and moisture from your home, and when outdoor humidity is very high, the system has to work harder to keep indoor air comfortable. A system that is undersized, low on refrigerant, or has dirty coils will struggle even more under those conditions. If your home feels sticky even when the AC is running, that is worth having checked out.
