HVAC Services Crestwood IL | Call Marcotte Mechanical

Common signs in our area include your AC blowing warm air, ice forming on the refrigerant lines, a hissing sound from the unit, and a noticeable spike in your energy bills. At Marcotte Mechanical, we first perform a precise leak detection test to locate the source. We then repair the leak, evacuate the system to remove any moisture, and recharge it with the correct amount of refrigerant specified by the manufacturer, restoring efficiency and cooling power to your home.

HVAC systems often freeze due to restricted airflow from dirty filters or blocked vents, or from low refrigerant levels. For Crestwood residents, a frozen unit is a sign of a problem that needs prompt attention. While you can turn the system off to let it thaw, running it in this state can cause serious damage to the compressor. We recommend calling us for an expert diagnosis. We'll identify the root cause—whether it's a leak, airflow issue, or mechanical problem—and perform the necessary repair to prevent a complete breakdown, especially during our peak summer or winter seasons.

Proactive maintenance is key. We recommend changing your air filter every 1-3 months, keeping outdoor units clear of leaves and debris, and ensuring all interior vents are unblocked by furniture or curtains. Scheduling a professional tune-up with Marcotte Mechanical before the heavy summer and winter seasons is the best step. Our maintenance checks catch minor issues like small leaks or airflow restrictions before they lead to major repairs, saving you money and ensuring reliable comfort for your family throughout the year.
