Case Study: High-Efficiency Furnace with MidAmerican Energy Rebate Coordination, Council Bluffs

This case study documents a high-efficiency furnace replacement in Council Bluffs with specific focus on MidAmerican Energy rebate coordination for Iowa customers. MidAmerican Energy serves Council Bluffs, Carter Lake, and other western Iowa customers with natural gas (and electric service in many areas), and operates rebate programs comparable to OPPD’s Nebraska programs but with different qualification criteria, application processes, and timing requirements. The case illustrates the coordination process for maximizing customer incentive capture across Iowa utility programs.

Customer Situation

The property is a 1999 two-story home in central Council Bluffs, 2,100 sq ft on a 8,400 sq ft lot. The customers (couple in their late 40s with two teenage children, both employed in healthcare with substantial dual incomes) had owned the home for 7 years (purchased 2018). They had completed substantial cosmetic renovations over their ownership but had not addressed HVAC equipment.

Equipment situation:

• 1999 original Trane 80% AFUE atmospheric furnace, 80K Btu/hr, 26 years old (substantially beyond useful life)
• 2017 Carrier 14 SEER R-410A AC, 3 ton, 8 years old, operating well
• 1999 furnace approaching predictable failure scenarios; substantial scaling and component aging observed during October maintenance plan tune-up
• Customer interest in modern efficiency and full rebate/credit utilization

Diagnostic Assessment

Consultation by Mark Tran (Cold-Climate Tech, 5 years) during October maintenance plan tune-up. Assessment time approximately 90 minutes including detailed customer discussion of incentive options.

Furnace Condition

• 1999 Trane 80% AFUE atmospheric furnace, 26 years old
• Combustion analysis: 38 ppm CO (elevated, indicating developing issues)
• Heat exchanger inspection: substantial scaling but no cracks yet
• Multiple components showing age (ID motor, gas valve, control board, blower bearings)
• Realistic remaining useful life: 1-2 heating seasons

Incentive Framework Discussion

Coordination of multiple available incentives for Iowa customers:

• MidAmerican Energy gas furnace rebate — $500 for qualifying 95+ AFUE installation (specific equipment qualification criteria apply)
• Federal Section 25C tax credit — $600 (30% × $600 max furnace credit)
• Combined incentive total — $1,100 in rebates and credits
• Customer eligibility verification: confirmed MidAmerican Energy gas customer (utility account documentation provided), federal tax liability adequate for credit utilization

Equipment Selection

Equipment selection coordinated with rebate qualification requirements:

• Lennox EL296V two-stage condensing furnace — 96% AFUE (exceeds 95% AFUE rebate minimum), 70K Btu/hr (right-sized from 80K based on Manual J)
• Equipment AHRI certification — verified for MidAmerican rebate qualification
• Existing AC retained — 2017 Carrier 14 SEER, 8 years old, operating well
• Two-stage compatible programmable thermostat — replaced existing basic programmable
• Chimney liner — for orphaned water heater after condensing conversion

Project Execution

Single-day installation, 7 hours total:

• Morning — Equipment delivery; old 1999 Trane atmospheric furnace removal; chimney liner installation for orphaned water heater (water heater 2020 replacement, only 5 years old); sidewall venting penetration through basement window header
• Midday — New Lennox EL296V positioning; gas, electrical, and ductwork connections; condensate management; two-stage thermostat installation
• Afternoon — System startup and commissioning; combustion analysis verification (5 ppm CO with new condensing equipment); two-stage operation testing; customer walkthrough including operation explanation and incentive documentation review

MidAmerican Energy Rebate Application Process

Iowa rebate coordination involves specific documentation requirements distinct from Nebraska OPPD process:

Documentation Provided to Customer

• Installation invoice with equipment model and serial numbers
• AHRI certificate confirming 96% AFUE rating
• MidAmerican Energy rebate application form (we provide pre-filled form for customer review and signature)
• Equipment manufacturer specifications and warranty documentation
• Iowa Plumbing & Mechanical Systems Board license documentation (#B-027841)

Customer Application Process

• Customer reviews and signs MidAmerican Energy rebate application
• Customer submits application to MidAmerican Energy with required documentation
• MidAmerican Energy processing time: typically 4-8 weeks from complete application
• Rebate provided as credit to customer’s utility account or check depending on customer preference
• We provide follow-up support if MidAmerican Energy requests additional documentation

Comparison to OPPD Process

• OPPD (Nebraska) processes rebate applications electronically through online portal; faster processing typical (2-4 weeks)
• MidAmerican Energy uses traditional paper application with longer processing time
• OPPD rebate amounts and MidAmerican Energy rebate amounts are comparable but not identical
• Customer eligibility verification differs slightly (each utility has its own account verification process)
• Both utilities provide modest customer incentives encouraging efficiency upgrades

Federal Section 25C Tax Credit Coordination

• Federal credit claimed on customer’s federal tax return for installation year using IRS Form 5695
• Credit amount: 30% × cost up to $600 max for qualifying furnaces (96% AFUE Lennox EL296V qualifies)
• Credit is non-refundable; customer must have sufficient federal tax liability to fully utilize the $600 credit
• Documentation provided: AHRI Reference Number, equipment specifications, installation invoice
• Credit application separate from MidAmerican Energy rebate application; both can be claimed for same installation

Results

• Modern condensing equipment — 96% AFUE vs prior 80% AFUE produces estimated 17% gas consumption reduction
• Two-stage operation — reduced first-stage capacity for most operation produces longer steady-state cycles
• Right-sized equipment — 70K Btu/hr matched to actual load vs prior 80K Btu/hr
• Combustion safety — 5 ppm CO new vs 38 ppm prior
• Combined incentives captured — $1,100 total ($500 MidAmerican + $600 federal)
• Customer documentation complete — prepared for both MidAmerican Energy application and federal tax credit claim
• Equipment warranty — 10-year parts coverage with manufacturer registration

Pricing

Total project cost: $6,400

• Lennox EL296V two-stage condensing furnace (70K Btu, 96% AFUE): $4,200
• Chimney liner installation: $1,485
• Sidewall venting penetration: $245
• Condensate pump: $215
• Two-stage programmable thermostat: $145
• Installation labor (7 hours): $885
• Materials, supplies, miscellaneous: $185
• Rebate application coordination and documentation: $40 (modest fee for our coordination support)

Net cost after rebates and credits:

• Project cost: $6,400
• MidAmerican Energy gas furnace rebate: -$500
• Federal Section 25C tax credit: -$600
• Net cost: $5,300

Iowa Customer Incentive Summary

Iowa customers (Council Bluffs, Carter Lake, and other western Iowa areas served by MidAmerican Energy) have access to comparable incentive frameworks as Nebraska customers, with some procedural differences:

• MidAmerican Energy rebates — gas furnace, heat pump, AC, smart thermostat, weatherization (various amounts depending on equipment and efficiency)
• Federal Section 25C tax credit — identical framework as Nebraska customers ($600 furnace, $2,000 heat pump caps)
• Iowa state incentives — modest additional programs through Iowa Economic Development Authority for some equipment categories
• Application processes — vary by program; MidAmerican has paper-based process while federal credits are claimed through tax filing
• Total incentive availability — typically $800-$2,500 across all programs for qualifying installations

Lessons from This Project

• Iowa customers (MidAmerican Energy service area) have access to comparable incentive frameworks as Nebraska customers, with different procedural requirements
• Equipment selection should consider rebate qualification criteria (95% AFUE minimum for most furnace rebate programs)
• Combined incentives (utility rebate + federal tax credit) substantially reduce net cost of qualifying installations
• Contractor coordination support during application process substantially improves customer experience and rebate capture
• Iowa MidAmerican Energy rebate processing takes longer than OPPD Nebraska processing (4-8 weeks vs 2-4 weeks); customer expectations should reflect this
• Documentation requirements differ between utility rebate applications and federal tax credit claims; both should be coordinated at installation completion
