Trusted HVAC Services in Palatine, IL 60074 - Subzero Heating And Cooling

In our Palatine climate, with its varying seasons and potential for dust, we recommend checking your air filter every month and replacing it at least every 90 days. For homes with pets or allergies, changing it every 30-60 days is best. A clean filter is your first defense against the clogged filters that commonly restrict airflow and strain HVAC systems in our area.

Common signs your boiler may be heading for a breakdown include strange noises (like kettling or banging), uneven heating between rooms, a sudden increase in your energy bills, or visible leaks or rust. Given the frequency of boiler issues locally, we recommend a professional maintenance check before each heating season to ensure reliable warmth all winter.

Absolutely. Over time, dust, pollen, and debris accumulate in ductwork, which is a major contributor to clogged filters and restricted airflow—a common issue here. Professional air duct cleaning removes this buildup, allowing your system to move air freely. This reduces strain, can lower energy costs, and improves overall indoor air quality for your home.
