South Chicago Heating - New Lenox's Local HVAC Repair

Uneven temperatures are a common sign of a thermostat malfunction, especially with our local temperature swings. The thermostat is your system's brain; if it's reading the room temperature incorrectly or has faulty wiring, it can't properly signal your furnace or AC. We can test your thermostat's calibration, check for electrical issues, and recommend a repair or an upgrade to a more reliable model to restore consistent comfort throughout your home.

We generally recommend changing standard 1-inch air filters every 1-3 months for most New Lenox homes. However, if you have pets, allergies, or noticeable dust, monthly changes are best. A clogged filter is the most common cause of restricted airflow, which makes your system work harder, increases energy costs, and can lead to premature breakdowns. During a routine maintenance visit, we can assess your filter type and home's specific needs to create an optimal schedule.

Key signs include weak airflow from your vents, your system running constantly but not reaching the set temperature, a noticeable increase in your energy bills, and excessive dust around your home. You might also hear whistling or rattling noises from the ductwork. If you notice these issues, check and replace your air filter first. If problems persist, it's time to call us for a professional inspection, as there may be a more complex blockage in the ductwork or a failing system component.
