4 Storeys Construction & Mechanical Services - Thornton's Trusted HVAC Repair

Our maintenance service is designed to keep your Thornton home's system running efficiently and reliably. We perform a comprehensive check, including cleaning components, inspecting electrical connections, checking refrigerant levels, and testing system controls. Regular maintenance can help prevent unexpected breakdowns, improve energy efficiency, and extend the life of your equipment, which is especially important with our local temperature swings.

Uneven heating is a common issue we address in Thornton homes. It can be caused by several factors, including ductwork that is improperly sized, leaking, or blocked, a failing zone control system, or an undersized furnace. During our free consultation, we'll diagnose the root cause—whether it's in the ducts, the equipment, or the home's insulation—and provide a clear solution to balance your home's comfort.

Our workmanship guarantee reflects our family's commitment to standing behind our work for our Thornton neighbors. It covers the labor and installation performed by our technicians. If an issue arises related to our installation or repair work within the guarantee period, we will return to fix it at no additional cost. It's our way of ensuring your long-term satisfaction and peace of mind.
