Accurate Control for Reliable Warmth
Your thermostat is the command center for your heating system — and when it’s inaccurate, outdated, or malfunctioning, your home never feels quite right. CRS Heating and Air Conditioning, Inc. repairs and replaces thermostats for furnaces, boilers, and heat pumps. Whether you need basic troubleshooting or want to upgrade to a smart model, we’re here to help.
If your heat won’t kick on — or keeps turning on and off too frequently — your thermostat may be the cause. Inconsistent temperatures, unresponsive screens, and rooms that never seem to get warm enough often point back to a control issue.
We’ll test system communication, wiring, settings, and power supply to confirm what’s happening.
Smart thermostats can adapt to your routines, save on energy bills, and keep your home comfortable in every season. You can set schedules, control settings from your phone, and monitor usage — all without needing to adjust the dial every time the weather changes.
We’ll help you choose a model that works with your system and install it cleanly with no guesswork.
CRS is woman-owned, based in McHenry, and committed to getting the details right — including the part of your system you interact with every day. We won’t upsell what you don’t need. We just make sure your heat runs the way it should.
