How We Helped a Lake in the Hills Homeowner Through a Cold Snap

A homeowner in Lake in the Hills called us in late November when his furnace had stopped producing heat the evening before. Our technician found a frozen condensate drain line — the PVC drain had iced over outside the home during an early cold snap, creating a pressure switch fault that prevented the furnace from operating. He cleared the blockage, insulated the exposed line section, and the system resumed normal operation. The fix took less than an hour.

Frequently Asked Questions

Why would a newer furnace fail in Lake in the Hills?
Even newer furnaces can experience igniter failure, pressure switch faults, condensate line freezing, or control board issues. Age is not a guarantee of reliability — annual maintenance and prompt attention to early warning signs are.
High-efficiency furnaces produce water vapor that drains through a condensate line. When that line exits the home through an exterior wall or runs through an unconditioned space, it can freeze during extreme cold, causing a pressure switch fault and shutting the furnace down.
Yes. We diagnose and repair smart thermostat wiring and communication issues that affect furnace operation. If your thermostat is sending incorrect signals or losing connection with the furnace, we can identify whether the problem is in the thermostat, the wiring, or the furnace itself.

Yes. McHenry County’s long heating season means furnaces here log more hours than in milder climates. Annual maintenance catches worn components before they fail, cleans burners and sensors, and verifies the system is operating safely and efficiently.

Watch for short-cycling, unusual sounds during startup or operation, rising heating bills without a change in usage, uneven heat between rooms, or a yellow or flickering burner flame. Any of these is worth a service call before the system fails on the coldest night of the year.
