Upgrading to a New HVAC System Might Be Easier Than You Think. When your air conditioner stops working during a Pennsylvania heatwave, it doesn’t take long before indoor temperatures soar. Allentown homes can become uncomfortable and even unsafe within hours, especially for older adults, young children, pets, and anyone with respiratory conditions. It’s essential to know what to do to protect your comfort, get your home back on track, and prevent additional strain or damage to your HVAC system.
Our team at Jack Lehr Heating, Cooling & Electric helps homeowners throughout the Lehigh Valley respond quickly when cooling systems fail during extreme summer weather. While some issues require professional repair, there are a few important steps homeowners should take before assuming the entire system has failed.
Start With the Thermostat and Air Filter
One of the most overlooked causes of sudden cooling problems is a thermostat setting issue or severely clogged air filter. During heatwaves, AC systems work overtime with longer cycles. That means your filters collect dust and debris faster than normal. Before calling for Allentown AC repair service, check:
- Thermostat settings and batteries
- Circuit breakers connected to the HVAC system
- Air filter condition
- Indoor vents blocked by furniture or rugs
- Outdoor condenser units covered with leaves or debris
Restricted airflow can even cause systems to overheat or freeze up. If the filter looks dirty, replacing it may help restore proper airflow and cooling performance.
Turn the System Off if It Is Struggling
Many homeowners keep running their AC system even if it’s blowing warm air or making unusual noises. During a heatwave, this places even more stress on electrical components, compressors, and blower motors. If the system is short cycling, rattling, or struggling to keep up, it’s usually best to shut the unit off and give us a call for professional service instead of forcing it to keep running and risk a potential breakdown.
Keep Sunlight and Heat Out of the Home
While waiting for AC repairs in Allentown, focus on keeping extra heat out of your home as much as possible. Close the blinds, blackout curtains, and any unused rooms to keep cooler air inside for longer. Avoid using ovens, dryers, or other heat-generating appliances during the hottest part of the day. You can also try running the bathroom exhaust fans for short periods during peak afternoon heat to help vent rising heat upstairs. This can be especially useful in older Lehigh Valley homes with limited attic ventilation. Venting some of that trapped heat can help rooms feel slightly less oppressive while waiting for repairs.
Know the Signs of a Serious AC Emergency
Some cooling issues should never wait through a heatwave. Burning smells, electrical buzzing, frozen coils, leaking water around the system, or complete airflow loss may point to larger HVAC problems that need immediate attention. If anyone in the home has medical concerns affected by heat exposure, temporary relocation to a cooling center, library, shopping center, or trusted family member’s home may also be the safest short-term solution while repairs are being scheduled.
