Kokomo winters test every commercial heating unit in town. When your furnace is the only thing keeping a store, office, shop, or warehouse above freezing, you need equipment that is sized correctly, installed carefully, and built to last.

- A load calculation to choose the correct size furnace
- Equipment options at several efficiency levels and price points
- Inspection of ductwork, gas piping, venting, and electrical connections
- Installation of gas furnaces, rooftop heating units, or unit heaters
- Gas line, vent, condensate, and electrical connections done to code

- Startup testing of gas pressure, temperature rise, airflow, and safety controls
- Carbon monoxide testing
- A walkthrough so your team knows how to operate and maintain the heater

Commercial Furnace Replacement in Kokomo, IN
When an old furnace fails or costs more to run than it is worth, replacement protects your comfort and your budget. A new heating unit often cuts heating bills and removes the worry of a breakdown on the coldest night of the year.
Signs You Need a Commercial Furnace Replacement:
- Your furnace is 15 to 20 years old or older
- Repairs are frequent and keep getting more expensive
- Heating bills keep rising with no change in operating hours
- The heater runs constantly but the building never feels warm
- The heat exchanger is cracked or heavily corroded
- The burner flame is yellow or you see soot around the furnace
- Some areas stay cold while others feel too warm
- Noise, odors, or short cycling continue after repairs
Our Commercial Furnace Replacement Services Include:
- A replacement consultation and written estimate
- Removal and disposal of your old furnace
- A new load calculation, since buildings change over time
- Installation of a matched furnace and controls
- Roof curb adapters when a new rooftop unit does not match the old opening
- Ductwork repair or sealing when it affects performance
- Venting and gas line updates when code requires them
- A programmable or smart thermostat upgrade
- Complete startup testing and safety checks
- Warranty registration and clear paperwork
Benefits of a New Commercial Furnace:
- Lower monthly heating bills with a high-efficiency heater
- More even temperatures across your space
- Quieter operation than older equipment
- Safer operation with modern safety controls
- Better indoor air quality
- Factory warranty coverage and peace of mind
What Efficiency Means for Your Kokomo Business
A furnace's AFUE rating shows how much fuel becomes heat. A rating of 80 percent means 80 cents of every fuel dollar heats your building. A 96 percent furnace turns 96 cents into heat. In a cold climate with a long heating season, the gap adds up quickly.
- Standard-efficiency furnaces cost less upfront
- High-efficiency furnaces cost more upfront and less to run
- The right choice depends on how long you plan to occupy the building and how much you use the heat
Sizing a Commercial Furnace the Right Way
Bigger is not better. An oversized furnace short cycles, wears out sooner, and leaves temperature swings. An undersized furnace never keeps up. We use a load calculation instead of a rule of thumb, which looks at insulation, windows, ceiling height, door traffic, and duct condition.
Planning Work Around Your Business
- We schedule work for early mornings, evenings, or weekends when possible
- We protect floors, ceilings, and stock during installation
- We coordinate crane or lift access for rooftop heating units
- We keep you informed from start to finish
Repair or Replace? Our Honest Advice
Not every problem needs a new heating unit. We compare the repair cost with the remaining life of your furnace and the savings a new heater would bring. If a repair makes sense, we say so. If replacement makes more sense, we show you why.
