Before You Start: Safety, Codes, and Permits

Installing central heating touches gas, high voltage, combustion vents, and local building codes. Pull the correct permits and schedule inspections with your municipality before starting. In Illinois communities like Yorkville, Aurora, and Naperville, inspectors expect proper load calculations, sealed ducts, and manufacturer-spec venting. Always shut off gas and power before work, use a calibrated gas leak detector, and follow NFPA fuel-gas guidelines and manufacturer instructions.

What pros bring to the table:

  1. Correct sizing with Manual J and duct design with Manual D.
  2. Safe venting and gas line sizing per code.
  3. Warranty protection and documented commissioning readings.

Fact check for peace of mind:

  • Summers Plumbing Heating & Cooling operates a 24/7 emergency hotline, so urgent issues are addressed day or night.
  • New installs are supported by strong warranties, and free quotes are available for furnace replacements.

Tip: Even confident DIYers usually hire a licensed HVAC contractor for gas piping, electrical connections, and final startup. That balance keeps you safe and protects your warranty.

"I needed a whole new heating system and they came within a couple of days and installed it. Now I can sleep in peace and not worry if our heating system will go out."

Step 1: Evaluate the Home and Identify Your Heating Type

Start with a whole-home assessment. Note insulation levels, window quality, existing ductwork, and space for equipment. Decide between:

  1. Gas furnace with ductwork
    • Common in the Midwest. Pairs easily with central AC.
  2. Boiler with radiators or in-floor hydronics
    • Even heat and comfort, but different piping than ducted systems.
  3. Heat pump or dual-fuel
    • High efficiency with electric heat pump plus a gas furnace for very cold snaps.

What to consider:

  • Fuel availability and pricing in your city.
  • Existing duct condition and size.
  • Desired efficiency and comfort features like variable-speed blowers and two-stage heat.

Local insight: Homes near the Fox River often have mixed-age additions. If you see uneven heating between the original structure and an addition, plan for a zoning strategy or a dedicated mini-split for that zone.

Step 2: Load Calculation and Proper Sizing

Correct sizing determines comfort and efficiency. A Manual J load calculation estimates heat loss room by room, factoring in square footage, insulation, windows, and air leakage.

Why it matters:

  • Oversized equipment short-cycles, wastes energy, and wears out faster.
  • Undersized systems run constantly and never catch up in January cold spells.

What you or your contractor will do:

  1. Measure rooms, ceilings, windows, and doors.
  2. Record insulation levels and air leakage points.
  3. Use software to produce the heating load and recommended equipment size.

Pro tip: In our region’s harsh winters, do not rely on rules of thumb like BTUs per square foot. Demand a printed load calc. It protects comfort and energy bills.

"Tech Mike and manager Dave are the best. They responded quickly to giving me a quote on a new furnace and air conditioner. We received quality work at a reasonable price."

Step 3: Duct Design, Zoning, and Indoor Air Quality

If you choose a forced-air system, correct duct design is vital. Use Manual D to size supplies and returns for each room. Seal all seams with mastic, not cloth tape. Insulate ducts that run through attics or garages.

Key actions:

  1. Create a duct layout with trunk and branch sizes.
  2. Add a return in larger rooms or each floor to balance airflow.
  3. Consider zoning with motorized dampers and a multi-zone thermostat for multi-story homes.

Indoor air quality add-ons:

  • High-MERV filtration or media filters to protect equipment and lungs.
  • Air purification options for allergies.
  • Humidification to keep winter air comfortable.

Common pitfall: Starving the system of return air. Uneven rooms and noisy vents often trace back to poor return design.

"RJ did a fantastic job of checking out our furnace system! He provided valuable suggestions regarding the appropriate furnace filters."

Step 4: Select the Right Equipment and Thermostat

Choose equipment that matches your load calc and comfort goals.

Furnaces:

  • Efficiency: Look for high AFUE options to cut gas usage.
  • Comfort: Variable-speed blowers and two-stage heat run quieter and hold steadier temperatures.

Heat pumps and dual-fuel:

  • Great for efficiency with a gas furnace backup for deep cold. Many are compatible with smart thermostats.

Thermostats:

  • Smart thermostats can trim energy use and provide remote control.
  • Verify compatibility and wiring. Some systems need a C-wire or an add-a-wire kit.

Local note: Many older Fox Valley homes still have mercury thermostats. Upgrading yields better control and savings.

"Felipe came to install a thermostat... he made many suggestions and they all worked... Kudos to Felipe for doing an outstanding job."

Step 5: Place and Set the Furnace or Air Handler

Position the unit on a level platform with clear service access. Follow manufacturer clearances from walls and combustibles.

Actions to take:

  1. Set vibration pads to reduce noise.
  2. Install a new metal plenum and transition to the trunk line without sharp turns.
  3. Add a properly sized return drop and filter rack.
  4. For condensing furnaces, install condensate drain with a trap and neutralizer if required.

Safety focus:

  • Check venting category. Use the correct flue material and slope.
  • Maintain required clearances to combustibles.
  • Do not reuse failing flexible connectors or corroded vent pieces.

Step 6: Gas Line, Venting, and Electrical Connections

This step is where most homeowners bring in a licensed pro.

Gas piping:

  • Size the line for the total connected load and distance.
  • Use approved fittings, drip legs, and shutoffs.
  • Perform a pressure test and leak check with an electronic detector.

Venting:

  • Verify combustion air and follow vent length, pitch, and termination rules.
  • For sealed-combustion units, run intake and exhaust per spec to avoid recirculation.

Electrical:

  • Dedicated circuit, correct breaker size, and proper grounding are required.
  • Low-voltage thermostat wiring must match the control board terminals.
"Summers heating and cooling always comes out to work on my dad’s boiler... Efrain... installed [a new] thermostat same day... programmed [the] thermostat for me... great company, would recommend."

Step 7: Connect Ducts, Balance Airflow, and Seal Everything

Once the unit is placed and powered, complete your duct connections.

Best practices:

  1. Transition smoothly from the plenum to trunks to reduce static pressure.
  2. Seal all seams and joints with mastic, then insulate as needed.
  3. Install balancing dampers on branch runs for fine-tuning.
  4. Confirm adequate return air path from each major room.

Airflow targets:

  • Set blower speed to meet the required CFM. Many variable-speed units allow precise adjustments.
  • Expect quiet, even airflow when balanced correctly. Whistling or rattling often signals a restriction or loose fitting.
"Eduardo... went out of his way to make the installation seamless. Him and his team also installed my furnace several years ago and did an incredible job."

Step 8: Commissioning, Safety Checks, and Final Tuning

Commissioning is where performance and safety are verified and documented. Do not skip this step.

Checklist:

  1. Startup per manufacturer procedure.
  2. Measure static pressure, supply and return temperatures, and total system CFM.
  3. Verify gas pressure and combustion with a calibrated analyzer where applicable.
  4. Check venting draft and confirm no flue recirculation.
  5. Verify thermostat programming, heat stages, and fan profiles.
  6. Document readings for warranty and future service.

Final homeowner walkthrough:

  • Filter changes, thermostat schedules, and basic maintenance tasks.
  • Warranty registration and contact info for support.
