Best HVAC Repair in Mequon, WI 53097.0 - Mirek's Heating & Air Conditi Oning

A cracked heat exchanger is a serious safety issue, as it can allow carbon monoxide to leak into your home. Warning signs include a strong, unusual odor (often described as formaldehyde-like), visible soot around the furnace burner, rusting on the vent pipe or furnace itself, and moisture or visible cracks on the exterior of the heat exchanger. You might also notice your furnace cycling on and off more frequently. If you suspect this common local problem, shut off the furnace and contact us immediately for a professional inspection.

Refrigerant leaks are a frequent issue for AC systems in our area, often due to corrosion from seasonal changes or wear on connections and coils. Unlike a car's gas, refrigerant isn't 'used up'; if the level is low, there's a leak. Common sources are the evaporator coil, condenser coil, or service valve schrader cores. We use advanced electronic leak detectors and UV dye to pinpoint even the smallest leaks. Simply topping off the refrigerant is not a fix—it's a temporary bandage that leads to higher bills and potential compressor failure. We find and repair the leak properly to restore efficiency and cooling power.

Proactive, seasonal maintenance is the best defense against the heat exchanger and refrigerant issues common in our climate. Our comprehensive tune-up includes a combustion analysis and visual inspection of the heat exchanger for early signs of stress or micro-cracks, catching problems before they become hazardous. For your AC, we check refrigerant pressure, inspect coils and connections for corrosion, and clean the system to maintain peak efficiency and reduce strain that can cause leaks. This neighborly care extends your system's life, improves safety, and helps avoid costly emergency repairs during our hottest and coldest months.
