Highland is one of the most densely developed communities in Lake County, with a housing stock that spans nearly a century of residential construction. The neighborhood streets are lined with homes built in the 1940s and 50s alongside ranches from the 60s and 70s, and many of those properties have been updated over the years with newer HVAC systems that now serve aging ductwork and building envelopes that were never designed around modern cooling loads. When summer humidity settles in and temperatures push into the 90s, those systems carry a heavy burden.
All American HVAC has over 25 years of combined experience serving communities like Highland throughout Northwest Indiana. We understand the unique demands older homes place on air conditioning systems, and we bring that knowledge to every service call we run in this area.
Working in a community with Highland’s age and housing density means encountering systems in every stage of their life cycle. We work on older equipment that has been running for decades and newer systems installed as replacements in homes that haven’t had significant updates to the ductwork or building envelope. Both situations require careful diagnosis to make sure the repair we do is appropriate for the whole system, not just the part that failed.
Our services include refrigerant leak detection and correction, capacitor and contactor replacement, compressor evaluation and repair, evaporator coil cleaning, condensate drain line clearing, thermostat service, and blower motor repair. We also look at whether the system is sized and configured correctly for the home, since mismatches between equipment capacity and actual load are a frequent hidden cause of poor performance in older Highland properties.
In an older home, some AC problems can disguise themselves as normal quirks. These signs mean it’s time to call a technician.
Older homes in Highland often have systems working harder than they should just to compensate for building inefficiencies. A repair call now can clarify whether the problem is the system itself or something larger at play.
The age of Highland’s housing stock is the dominant factor behind most of the AC problems we see here. Ductwork in homes built before the 1980s was often installed without modern sealing standards, and decades of settling, pest activity, and temperature cycling have left many systems leaking conditioned air into attic and crawlspace areas where it does no one any good. The result is a system that runs constantly but struggles to actually cool the living space.
Electrical component wear is also a persistent issue. Capacitors, contactors, and blower motors in systems that have been running for 10 to 15 years are approaching the end of their expected service life, and the long cooling seasons in Northwest Indiana accelerate that timeline. Refrigerant leaks are another common finding, particularly in older copper refrigerant lines that have experienced corrosion or vibration-related stress over many years of operation. Highland homeowners who keep up with regular service tend to avoid the worst of these outcomes.
We got a call from a homeowner named Brenda in a 1960s ranch home on the north side of Highland. She had been dealing with a system that cooled the front of the house reasonably well but left the back bedrooms noticeably warmer all season. She had adjusted vents, changed filters, and even had someone look at the thermostat, but nothing had made a meaningful difference.
When our technician went through the home, he found a combination of partially collapsed flex duct in the attic serving the rear of the house and a low refrigerant charge that was limiting the system’s total output. Neither issue alone would have been enough to create the problem Brenda was describing, but together they were more than enough. We repaired the ductwork, located and corrected the refrigerant leak, and recharged the system. On the follow-up call the next day, Brenda said the back rooms were cooling better than they had in years.
Highland homeowners need a team that understands older homes, honest diagnostics, and repairs that actually last. That’s what we’re built on.
We serve Highland because we know this community, and we treat every call here with the same care we’d give our own neighbors.
Yes. We work on systems of all ages and are familiar with the equipment and ductwork configurations common in homes built from the 1940s through the 1980s. Whether we’re repairing an aging system or servicing a newer unit in an older home, we know what to look for.
It can contribute to it, yes. When a system has to compensate for significant duct leakage, it runs longer cycles and works under more stress than it was designed for. Over time, that accelerates wear on the compressor and other components. Addressing duct problems alongside system repairs is often the more complete solution.
If the system isn’t running at all, the issue is usually electrical, such as a failed contactor, tripped breaker, or thermostat problem. If it’s running but not cooling, the cause is more often refrigerant, airflow, or coil-related. Either way, a technician can pinpoint the cause quickly with the right diagnostic steps.
Scheduling a maintenance visit in the spring before heavy cooling demand starts is the best preparation. A technician will check refrigerant levels, clean the coils, clear the drain line, test electrical components, and verify airflow so the system is ready to handle whatever the summer brings.
Yes. All American HVAC provides 24-hour emergency service. If your system stops working outside of business hours, you can still reach us and we’ll get a technician out as quickly as possible.
