Leto Plumbing & Heating, Inc. repairs furnaces and boilers in Plainfield, and when yours quits at 11 p.m. in January or starts making sounds it shouldn't, you reach us directly at (815) 609-3150, 24/7. Richard Leto and his team have diagnosed heating failures across Plainfield and Chicagoland for 24 years, with 53 Google reviews averaging 4.8 stars.

Heating Systems We Repair in Plainfield
Older Plainfield neighborhoods have boilers and steam; newer subdivisions run gas forced air. We repair all of them.
Gas Furnace Repair
Igniters, cracked heat exchangers, limit switch trips, blower motors. Common parts are on the truck.
Boiler and Radiant System Repair
Circulator pumps, zone valves, and pressure problems in hydronic systems.
Heat Pump Repair
We check refrigerant charge, reversing valve, defrost controls, and auxiliary heat before concluding anything.
Thermostat and Control Issues
Many 'furnace failures' are thermostat problems, so we check controls first.
Ductless Mini-Split Heating Repair
Running but not heating, or throwing error codes: we diagnose indoor and outdoor units.
Steam Heating System Repair
Venting, steam traps, and pressure problems on systems many technicians have never touched.
WARNING SIGNS
Signs Your Heating System Needs Professional Attention
Act on these before a repair becomes an emergency.
No Heat or Weak Heat
A failing heat exchanger, restricted flue, or weakening blower motor.
Short Cycling
Fires, runs two minutes, shuts off: a limit switch or heat exchanger problem that worsens with use.
Unusual Noises
Banging, squealing, or rattling each point to a specific component under stress.
Yellow or Orange Burner Flame
The flame should be blue with a small yellow tip. Yellow or orange means a combustion problem and carbon monoxide risk. Stop the system and call.
Increasing Energy Bills
Efficiency drops before total failure, and it's usually fixable.
Uneven Heat Room to Room
Duct problems, a failing blower, or zone controls. Some older Plainfield homes have ductwork undersized from the original install; airflow and static pressure readings find it.

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!
