Commercial Furnace Repair in Peru, IN

Why Is My Commercial Furnace Not Heating?

Several problems can stop a furnace from producing heat.

• A dirty filter that restricts airflow
• A failed igniter or dirty flame sensor
• A faulty thermostat or building control
• A broken draft inducer motor or pressure switch
• A stuck gas valve
• A tripped limit switch from overheating

Why Does My Furnace Keep Turning On and Off?

Short cycling usually points to overheating, a dirty flame sensor, a clogged filter, or a control problem. Short cycling wears out parts quickly, so have it checked soon.

What Is That Noise Coming From My Heating Unit?

• Banging: Delayed ignition or expanding ductwork
• Squealing: A worn blower motor or belt
• Rattling: Loose panels or parts
• Grinding: Failing motor bearings, which needs prompt attention

Repairs We Perform:

• Igniter and flame sensor service
• Draft inducer and pressure switch replacement
• Blower motor, capacitor, and belt repair
• Gas valve and control board repair
• Thermostat replacement
• Limit switch and safety control repair

Commercial Furnace Maintenance in Peru, IN

How Often Should We Service Our Commercial Furnace?

Once a year, ideally in early fall before heating season starts. Buildings with heavy use may benefit from a second visit mid-season.

What Does a Furnace Tune-Up Include?

• Burner and heat exchanger inspection
• Flame sensor and igniter cleaning
• Blower motor and capacitor testing
• Gas pressure and temperature rise check
• Carbon monoxide testing
• Filter check
• Venting inspection
• Thermostat calibration and safety control testing

Is Commercial Furnace Maintenance Worth It?

Yes. Maintenance lowers the chance of a winter breakdown, keeps heating costs down, supports safer operation, and often keeps your manufacturer warranty valid. A cleaned and tested heater also lasts longer.

Warning Signs Peru Businesses Should Not Ignore

• A yellow or flickering burner flame
• A burning smell or the odor of gas
• Soot around the equipment
• Staff reporting headaches or nausea when the heat runs, which can signal carbon monoxide
• A carbon monoxide alarm sounding

If you suspect carbon monoxide or smell gas, evacuate the building and call emergency services or your gas utility from outside.

Should We Repair or Replace Our Furnace?

Repair makes sense when:

• The furnace is under 10 to 12 years old
• The repair is minor
• Heating bills have stayed steady

Replacement makes sense when:

• The furnace is over 15 years old
• Repairs keep adding up
• The heat exchanger has cracked
• Heating bills keep rising

Our technicians give you both options with clear numbers and a plain recommendation.

What Makes Peru Winters Hard on a Commercial Heater

Cold stretches keep a heating unit running for long periods. Long run times wear the igniter, blower motor, capacitor, and burners faster, and a furnace that is already weak can fail when you need it most. A fall tune-up gives your technician a chance to replace worn parts before the first long cold stretch.

Tips to Keep Your Peru Commercial Furnace Running Well

• Change filters on schedule
• Keep supply and return vents open
• Keep storage away from heating equipment
• Test carbon monoxide detectors each season
• Schedule a tune-up each fall

Common Questions About Commercial Furnace Service in Peru

How long does a furnace repair take? Many repairs finish during one visit. If a part must be ordered, we explain the timeline before we leave.

Do you service every brand of commercial heating unit? Our technicians work on all major brands, including gas and high-efficiency models.

Can a tune-up really prevent a breakdown? Often yes. Cleaning and testing the igniter, flame sensor, and blower catches the worn parts that fail most often.

How long should a commercial furnace last? Most last 15 to 20 years with regular maintenance.

Equipment Types We Service in Peru

• Gas furnaces, including standard and high-efficiency models
• Propane furnaces
• Rooftop heating units
• Gas unit heaters
• Single-stage, two-stage, and variable-speed furnaces

How to Prepare Your Peru Building for Winter

• Replace filters before the first cold week
• Test thermostats and building controls
• Run the heat briefly in early fall to check for odd smells or noises
• Clear boxes and stock from vents and equipment areas
• Book a professional tune-up

A brief burning smell on the first run of the season is common, since dust burns off the heat exchanger. A strong or lasting smell is not normal and needs a technician.
