Read This First: Safety, Permits, and When to Call a Pro

Installing central heating is a system-level project that touches gas, electricity, combustion air, venting, and indoor air quality. Safety and code compliance come first.

1. Permits and inspections

   • Most municipalities in Chicagoland require a mechanical permit for a new furnace or heat pump installation and an electrical permit for new circuits or rewiring. Always verify with your city before work begins.
   • Inspections protect you and your home’s resale value. Skipping permits can void warranties and insurance coverage.

2. When DIY stops

   • Gas line connections, new circuits, and vent penetrations should be handled by licensed professionals.
   • If your installation involves combustion venting, sealed combustion terminations, or refrigerant handling for a heat pump, hire a pro.

3. Why ABC

   • NATE-certified technicians, available 24/7/365 when you need help fast.
   • No-Surprises Pricing. The quote you approve is the price you pay.

"Excellent job troubleshooting my HVAC and heating issues."

Step 1: Plan the System Like a Pro

A great central heating system starts on paper. Proper planning reduces noise, boosts comfort, and prevents early breakdowns.

1. Load calculation

   • Ask for an ACCA Manual J heat load calculation. This measures how much heat your home loses on a design winter day. It prevents oversizing that causes short cycling, uneven rooms, and high bills.

2. Duct design

   • Ducts are the highway for warm air. An ACCA Manual D layout sizes trunks and branches correctly. Include return air paths for closed rooms so the system can breathe.

3. Equipment pairing

   • Decide between a gas furnace, heat pump, or a dual-fuel setup. In Chicagoland, many homes pair a high-efficiency furnace with a heat pump for shoulder seasons.

4. Thermostat strategy

   • Programmable or smart thermostats save energy and improve comfort. Plan the low-voltage wiring path and location away from drafts or sun.

Pro tip: Request a static pressure target in the design. Low static equals quiet, efficient airflow.

"He came to service our heating system and he really did a great job and explained me everything in detail."

Step 2: Choose the Right Equipment

Picking equipment is about comfort, longevity, and efficiency.

1. Furnaces

   • High-efficiency condensing furnaces deliver strong heat and can vent through PVC. Look for variable-speed blowers for quieter, even heat.

2. Heat pumps

   • Cold-climate models now handle Midwest winters better than ever. They provide efficient heat and can pair with a furnace for dual-fuel control.

3. Sizing

   • Let Manual J guide the size. Bigger is not better. Right-sized equipment runs longer, quieter cycles and lasts longer.

4. Indoor air quality

   • Consider a high-MERV media filter, whole-home humidifier, and an air purifier. These reduce dust, improve comfort, and protect your lungs.

5. Warranties and guarantees

   • ABC is a Carrier Factory Authorized dealer. You get top-tier systems and strong warranty support, plus ABC’s No-Nonsense Parts & Labor Warranty and satisfaction guarantees.

"Thank you for the thorough evaluation of our HVAC system."

Step 3: Prepare the Site and Power

This is where careful prep prevents headaches later.

1. Clearances and platform

   • Set the furnace or air handler on a level platform with required service clearances. Use isolation pads to reduce vibration.

2. Combustion air and return paths

   • Provide adequate combustion air for gas units, or use sealed combustion. Verify return air sizing to avoid whistling grilles and hot-cold swings.

3. Electrical readiness

   • Confirm a dedicated circuit, correct breaker size, and a service disconnect within sight of the unit. Label all circuits.

4. Condensate management

   • For condensing furnaces and some air handlers, route condensate with a trap and slope to a drain. Include a safety switch to prevent overflow.

Quick checklist before proceeding:

1. Permits posted
2. Platform level
3. Combustion air verified
4. Electrical circuit sized and labeled
5. Condensate trap and drain planned

Step 4: Install and Seal Ductwork

Ducts make or break system performance. Poor ducts waste energy and create uneven rooms.

1. Layout and sizing

   • Follow the Manual D plan. Keep runs short and smooth. Use gradual transitions, not abrupt reductions.

2. Sealing and insulation

   • Seal every joint with mastic or UL 181 foil tape. Insulate ducts in unconditioned spaces to stop heat loss.

3. Returns and balancing

   • Provide adequate return air from bedrooms and large rooms. Install balancing dampers where needed for even delivery.

4. Aeroseal option

   • ABC offers Aeroseal duct sealing that seals leaks from the inside, a strong upgrade for older homes in Chicago, Evanston, and Skokie.

"ABC's representative was very thorough in his maintenance check and servicing of my HVAC system... Air-duct cleaning was also performed. Five-star rating."

Step 5: Venting and Combustion Safety

Venting is a life-safety task. If you are not trained, stop and call a pro.

1. Vent material and slope

   • High-efficiency furnaces typically use PVC or CPVC with proper slope back to the furnace for condensate drainage. Follow manufacturer specs for size and length.

2. Termination location

   • Keep intake and exhaust clear of snow lines, shrubs, and windows. Maintain required clearances from doors and fresh air intakes.

3. Category I metal venting

   • If using a standard efficiency furnace with metal venting, confirm correct draft and chimney liner sizing to prevent backdraft.

4. Carbon monoxide safety

   • Install CO detectors on each floor. ABC’s tune-up includes specific safety checks for carbon monoxide leaks.

"Chris came to look at the system... the system is fully operational and we have heat again. Thanks Chris."

Step 6: Gas, Electrical, and Thermostat Connections

Precision here equals reliability and safety.

1. Gas line and shutoff

   • Use the correct pipe size and test with approved leak detection. Install a drip leg and accessible shutoff valve.

2. Electrical connections

   • Verify correct polarity, tight lugs, and proper grounding. Tie in the service disconnect and verify GFCI where required.

3. Thermostat control

   • For smart stats, wire C for constant power. Map W for heat, Y for cooling or heat pump, G for fan, and O/B for heat pump reversing where applicable.

4. Heat pump considerations

   • Outdoor unit placement should be level and above snow height. Add a crankcase heater if specified and ensure clear airflow on all sides.

Tip: Photograph all wiring connections and label each conductor. It speeds troubleshooting later.

Step 7: Startup and Professional Commissioning

Commissioning transforms an installation into a system that performs as promised.

1. Pre-start checks

   • Remove shipping blocks, verify blower orientation, and confirm filter installation. Open all supply and return grilles.

2. Combustion and airflow tests

   • Measure temperature rise, static pressure, and verify blower speed for the designed airflow. Dial in gas pressure to manufacturer spec.

3. Safety tests

   • Test high-limit, pressure switches, and flame sensor signals. Confirm inducer and ignition sequences.

4. Thermostat programming

   • Set schedules, fan modes, and dual-fuel balance points if applicable.

Why it matters: Proper commissioning cuts callbacks, lowers bills, and keeps rooms in Chicago, Schaumburg, and Arlington Heights evenly comfortable.

Step 8: Finish Strong with Maintenance and Guarantees

A clean, tuned system runs safer and lasts longer. Lock in maintenance now.

1. Ultimate Heating System Tune-Up

   • ABC’s annual tune-up goes beyond a basic check. It includes a full system cleaning, airflow analysis, new filter, carbon monoxide safety checks, lubrication of moving parts, and thermostat testing.

2. Membership value

   • ABC’s Ultimate Advantage Club starts at $19.97 per month. You get four automatic maintenance appointments per year across your home, priority scheduling, waived service call charges during business hours, extended warranty protection, and members-only discounts.

3. Guarantees you can bank on

   • Satisfaction Guaranteed and No-Surprises Pricing mean no curveballs. ABC stands behind its work with strong parts and labor warranties.

4. Indoor air add-ons

   • Ask about whole-home humidifiers for dry winters, air purifiers, and duct cleaning to keep dust down.

Common Mistakes to Avoid

1. Skipping the load calculation and oversizing the furnace or heat pump.
2. Reusing undersized or leaky ducts without sealing and balancing.
3. Incorrect vent slope or termination that leads to icing or backdraft.
4. No trap or safety switch on the condensate line.
5. Ignoring static pressure. High static means noise, low airflow, and early failures.

Cost, Timeline, and Local Tips

1. Typical timeline

   • One day for straight furnace replacements with existing ducts. Two to four days for duct revisions, IAQ add-ons, or a new heat pump.

2. Cost drivers

   • System efficiency, variable-speed blowers, duct upgrades, and accessories like humidifiers or air purifiers.

3. Local insight

   • In older homes across Evanston, Skokie, and Des Plaines, returns are often undersized. A small return upgrade can transform room-to-room comfort.

4. Emergency coverage

   • ABC responds 24/7/365 for heat outages. If your system fails on a holiday, we are on call.
