HVAC & Water Heater Services in O'Fallon, MO | Swiss Air Heating & Cooling

For O'Fallon residents dealing with common indoor air quality issues like pollen or dust, we offer a multi-step approach. It often starts with a building energy audit to assess your home's specific needs. From there, we can recommend and install solutions such as advanced air filtration systems, UV lights to neutralize airborne pathogens, and whole-home humidifiers or dehumidifiers to balance moisture levels. Our goal is to create a cleaner, healthier living environment tailored to our local climate.

Our preventative maintenance service is designed to keep your system running reliably and efficiently. A typical visit includes a thorough inspection, cleaning of key components, checking refrigerant levels, testing electrical connections, calibrating your thermostat, and ensuring all safety controls are functioning. Regular maintenance can help prevent unexpected breakdowns, especially during our hot St. Louis summers, and is key to extending the lifespan of your equipment while maintaining optimal performance.
