Do Heat Pumps Work in Illinois Below-Zero Winters? In Illinois winters, heat pumps are often promoted as an efficient alternative to gas furnaces—especially because they move heat rather than create it from combustion. But many homeowners still worry about the same question: what happens when temperatures plunge below zero? While heat pumps don’t “stop working” at extreme cold, their efficiency generally declines as outdoor temperatures fall. The key variable is how the system is designed and managed—particularly its capacity range, defrost strategy, and whether a supplemental heat source is available. How heat pumps behave as temperatures drop Most air-source heat pumps use electricity to transfer heat from the outside air to the home. As the outdoor air gets colder, the heat available to capture decreases and the system has to work harder. That increased workload can reduce heating efficiency (often measured by metrics like COP o ... Read more »
How to Read a Sewer Video Inspection Report
Sewer video inspections use a camera pushed through your drain or sewer line to document the inside condition of the pipe. The resulting report typically combines still images, video segments, measurements, and a scoring or description of defects. Learning what you’re looking at helps you ask the right questions and make informed decisions about repairs.
Although each company formats reports differently, most follow the same logic: identify where problems are, describe what the camera sees, grade severity, and recommend actions. Below are the most important sections—and how to interpret what your plumber is actually showing you.
1) Locate the problem: footage, distance, and direction
Most sewer reports reference footage that corresponds to a known point along the line—often using distance markers such as “distance from cleanout” or a similar measurement. The plumber may also indica ... Read more »
