Why Plainfield Furnaces Need Annual Service
Plainfield's sub-zero stretches froze sump pump lines for one of our customers in February 2026, and that kind of cold exposes deferred maintenance fast. A dirty burner and clogged filter make the system work harder and raise energy bills. The bigger risk is safety: a cracked heat exchanger can let carbon monoxide into the living space, and you can't see it without opening the unit. We check it every time.
Simple Furnace Care Between Service Visits
These keep small problems small between visits. They don't replace a professional inspection: the heat exchanger, amp draw, and safety controls aren't DIY checks.
- Clean or replace your filter every 1-3 months depending on usage
- Make sure the blower motor is functioning properly, listen for unusual noise or vibration
- Make sure all household vents are free and clear of furniture and debris
- Remove all flammable objects from around your furnace

What Plainfield Homeowners Ask Us
How often should Plainfield homeowners schedule furnace maintenance?
Once a year, ideally in early fall before heating season. If your system is older than 10 years or you've skipped a cycle, call before the temperature drops. A single tune-up often catches two or three things that would have become repair calls.
What happens if I skip furnace maintenance for a season in Plainfield?
Short term, probably nothing obvious. Long term: lower efficiency, higher gas bills, and faster wear. The heat exchanger worries us most, since a crack can go undetected and carbon monoxide exposure is a real risk. Most February emergency calls trace back to maintenance skipped the prior fall.
Can a furnace tune-up be combined with a thermostat upgrade in Plainfield?
Yes. If your thermostat is older or uncalibrated, a smart thermostat installation during the tune-up saves a second trip charge and gets the new thermostat set up correctly from the start. We give a free estimate for the full scope before we begin.
What should I do if my furnace stops working on a cold night in Plainfield?
Call (815) 609-3150. We answer 24 hours a day, nights and weekends included, and cover Plainfield and the broader Will County area. One customer's furnace went out on a sub-zero February morning and was running again within two hours of the call.

Kathy WendellWritten on behalf of my mom Annie: I am very satisfied with Chris Leto's service. He addressed the issue quickly and professionally. Charged a fair price.
Alvin KIn February of 2026 I used Leto Plumbing & Heating on two occasions. First for an emergency after hours weekend call when my sump pump line was frozen during our recent sub-zero weather. The second was a routine maintenance call to flush my hot water heaters. Both times the individuals that came out were pros who were friendly, knowledgeable and got the job done right the first time. Would highly recommend!

Ted KawczynskiVery happy with the service received by Leto plumbing. Starting with phone call made, very nice and was able to get us scheduled next day. Chris, technician, was earlier than originally expected (which was great), he explained everything, was very courteous and timely. Extremely happy with service provided and will be calling Leto for any future needs.
