HVAC Repair Collinsville IL | Call Kelvin Heating and Cooling

In our area, we frequently handle short-cycling furnaces and boiler system breakdowns. Short cycling, where your furnace turns on and off too often, is often caused by airflow restrictions, an oversized unit, or a faulty sensor. For boilers, common issues include failed circulator pumps or pressure problems. As a local company, we're familiar with these specific challenges and can diagnose and repair them efficiently to restore your home's warmth.

Regular maintenance is crucial for the efficiency and longevity of your system, especially with our varied Illinois weather. A professional tune-up helps prevent unexpected breakdowns during extreme heat or cold, improves energy efficiency to lower your bills, and ensures safe operation. Our maintenance service includes cleaning, inspecting, and adjusting critical components to keep your HVAC system running reliably all year.

Our water heater installation is a complete service. We handle the removal of your old unit, proper installation of the new water heater—ensuring it meets all local codes—and a thorough check of all connections and pressure settings. We'll explain your options, from traditional tank to tankless models, and provide a clear, upfront quote so you know exactly what to expect for your Collinsville home.
