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 »
Noisy Pipes: What the Sounds Mean and When to Call a Plumber Unusual sounds coming from your pipes can be more than an annoyance. Some noises point to simple fixable causes like air in the lines or loose hardware, while others can indicate a problem that may worsen—such as a failing pressure regulator, worn cartridges, or a blockage in the drain system. Here’s a practical guide to common pipe sounds, what they typically mean, and when you should stop troubleshooting and contact a licensed plumber. Hissing or whistling A steady hissing or high-pitched whistle often comes from water flowing through a partially closed valve, a worn faucet cartridge, or a leak in a supply line. In some homes, it may also relate to water pressure that’s too high—especially if the sound increases when multiple fixtures run. Try turning the fixture off and back on, and confirm the shutoff valves are fully open. If the noise persists at the same int ... Read more »...
