Stewarts Heating & Cooling - Oconto's Certified HVAC Repair

In our area, poor indoor air quality often stems from tightly sealed homes trapping pollutants, seasonal allergens, and dust from local farming or industry. At Stewarts, we start with a comprehensive air quality assessment to identify specific issues like mold spores, VOCs, or particulate matter. Our solutions include professional duct cleaning to remove built-up contaminants, installing advanced air purifiers or UV light systems, and recommending proper humidity control to create a healthier living environment for your family.

Yes, pilot light failures are very common in older furnaces common to Oconto homes, often due to a dirty or faulty thermocouple, drafts, or issues with the gas supply. Our technicians are experts in diagnosing the root cause. We can usually perform a repair, such as cleaning or replacing the thermocouple. However, if your furnace is frequently failing or is over 15 years old, we might recommend a more reliable and energy-efficient replacement to ensure your safety and comfort during our cold winters, potentially saving you money on future repairs.

We recommend biannual maintenance—once in the fall for your heating system and once in the spring for your cooling system. This proactive schedule is crucial for our climate. The fall tune-up includes checking and cleaning pilot assemblies, testing for carbon monoxide leaks, and ensuring efficient operation to prevent mid-winter breakdowns. The spring service focuses on airflow, coils, and drainage to maintain good air quality and cooling efficiency. This regular care helps catch small problems before they lead to poor air quality or system failures, extending your equipment's life.
