Background

Vanessa O. continues building her Wasatch Front rental property portfolio with deliberate focus on properties in walkable historic districts. The Ogden 25th Street District represents one of Utah’s premier urban revitalization successes: National Register Historic District designation, active restoration of late-19th and early-20th century buildings, vibrant restaurant and retail scene, growing residential demand from professionals seeking walkable urban living. Vanessa purchased the 25th Street mixed-use building in 2020 after the previous owner’s significant restoration investments (exterior masonry restoration, structural updates, ground floor commercial buildout, upper apartment renovation). The aged HVAC equipment serving the upper residential unit was not addressed during the previous restoration; Vanessa’s long-term ownership plan included scheduled HVAC replacement when equipment approached end-of-life. The 1985-era furnace had reached that point by 2024.

Historic Preservation Considerations

Ogden Historic Preservation Commission consultation (August 2024):
Pre-project consultation with Ogden Historic Preservation Commission to verify any required approvals for exterior modifications. Key considerations:

  • Vent system change: Original atmospheric B-vent ran through interior brick chimney chase terminating at original chimney top on roof. New PVC sealed combustion venting requires exterior wall penetration. Commission required documentation of: (a) least-visible exterior penetration location, (b) appropriate vent termination matching building character, (c) preservation of original brick chimney structure (cap and seal for future use rather than removal)
  • Equipment visibility: Outdoor AC condenser already located in side alley (installed 2018); no new outdoor equipment for furnace replacement
  • Interior modifications: Interior equipment replacement not subject to commission review
Commission approval:
Approval granted August 28, 2024 with conditions:

  • Vent termination on east alley wall (less visible than 25th Street facade)
  • Vent termination paint matched to brick masonry color
  • Original brick chimney structure preserved (capped and sealed, not demolished)
  • Interior original tin ceiling tiles must be protected during work
  • Photo documentation of pre- and post-work conditions submitted to Commission
Documentation maintained:
Detailed photo documentation throughout project. Pre-project, mid-installation, and post-installation photos submitted to Commission October 2024. Project compliance verified November 5, 2024 with no additional requirements.

Existing Equipment Context

Original 1985 furnace (being replaced):
  • Heil 80,000 BTU/hr atmospheric gas furnace, 80% AFUE
  • Single-stage operation
  • PSC blower
  • Atmospheric B-vent through original brick chimney
  • 39 years service age at replacement (exceptional longevity for single-stage equipment)
  • Located in upper unit utility closet adjacent to kitchen
Existing AC equipment (retained):
2018 Carrier 24ACA3 AC, 2-ton, 13 SEER, R-410A. 6 years service age, functioning normally. Refrigerant lineset routed from outdoor unit in side alley through brick exterior wall to indoor evaporator coil at furnace location. Lineset retained during furnace replacement with new evaporator coil matched to new furnace.
Ductwork:
Mid-1990s sheet metal ductwork installation (during prior renovation). Routes through dropped soffits and minimally-altered original building structure. No major modifications required during furnace replacement.
Thermostat:
1985-era manual mercury bulb thermostat (single-stage operation). To be replaced with modern smart thermostat as part of project.
Existing equipment condition assessment:
  • Heat exchanger borescope: surface oxidation but no cracks identified despite 39 years service
  • Combustion analysis (Testo 320): CO 42 ppm flue, O₂ 9.4% (high excess air), efficiency 73.8% (degraded from 80% nameplate)
  • PSC blower capacitor: 28 MFD (vs. 35 MFD nominal; 20% degraded)
  • Inducer motor: bearing wear with audible whine
  • Heat exchanger structural integrity: borderline acceptable but cascading component failures expected within 1-3 years

Equipment was functional but at end-of-life. Reactive maintenance pattern would have included emergency repairs through 2025-2027 with eventual catastrophic failure. Proactive replacement during off-peak season (September) provided controlled installation timing.

Equipment Selection and Specifications

Manual J load calculation (Ogden central elevation 4,330 ft):
  • 17.3% altitude derate per IFGC 304.1
  • Apartment heating load at ASHRAE 99% design (3°F for Ogden): 38,400 BTU/hr
  • Considerations: 11-foot ceilings increase volume vs. typical residential, masonry exterior provides thermal mass benefit, single exterior wall in alley orientation reduces total exterior wall area, second-floor unit benefits from ground floor heat rise (ground floor commercial maintains heating during business hours)
  • 60,000 BTU/hr nameplate furnace at altitude derate = 49,620 BTU/hr effective output, appropriately sized for 38,400 BTU/hr design load with margin
Furnace selection: Bryant 925SA
  • Model: 925SA60080V17 (60,000 BTU/hr input, 96% AFUE, single-stage)
  • Variable-speed ECM blower
  • Aluminized steel primary heat exchanger
  • PVC concentric sealed combustion venting
  • 10-year limited parts warranty (with registration)
  • Mid-tier residential equipment with excellent reliability track record
Why Bryant 925SA vs. higher-efficiency options:
Tenant rental property economics favor mid-tier equipment over premium tier:

  • Tenant pays utility costs directly (typical Utah rental pattern); efficiency benefits accrue to tenant, not Vanessa
  • Premium tier equipment (98% AFUE modulating) costs $4,000-6,000 more than mid-tier with relatively modest additional efficiency benefit at this consumption level
  • Bryant 925SA mid-tier 96% AFUE captures full IRA 25C and ThermWise/Wattsmart rebates without premium tier cost
  • Modulating equipment offers comfort benefits more relevant to owner-occupied homes than rental properties
  • Bryant 925SA proven reliability in rental property contexts
Matched evaporator coil:
Existing 2018 Carrier evaporator coil retained. Carrier and Bryant share parent company (United Technologies/Carrier Global Corporation) with matching coil specifications. Verified compatibility with new furnace blower CFM specifications.
Smart thermostat:
Honeywell T6 Pro smart thermostat replacing original 1985 manual mercury bulb thermostat. Mid-tier smart thermostat appropriate for rental property: Wifi connectivity, programmable scheduling, remote access for both tenant and Vanessa, energy reporting, compatible with smart furnace operation. Lower cost than premium smart thermostats (ecobee Premium, Carrier Infinity Touch) while providing core smart functionality.
Filter:
Upgrade from 1-inch builder filter to 4-inch MERV 11 media filter cabinet. Higher capacity supports longer filter intervals (3-6 months vs. 1-2 months for 1-inch filters).

Rental property considerations vs. owner-occupied:
Vanessa’s project economics: $7,800 capital investment vs. avoided emergency replacement costs ($11,000-13,000 estimated emergency replacement cost during heating season), plus equipment 20-25 year service life ensures no replacement needed during her ownership plan. Tax depreciation: residential rental property HVAC equipment depreciated over 27.5 years per IRS Section 168. Approximately $283 annual depreciation deduction. After-tax economic value of project: positive net present value over 25-year residence in portfolio.

Post-Installation Outcomes

September-November 2024 (initial operation):
  • New furnace operating at design specifications
  • Tenant comfort noticeably improved (smart thermostat replacing manual mercury thermostat enables proper scheduling)
  • Tenant reported reduced gas bill: October 2024 bill ~$28 vs. October 2023 bill ~$42 (33% reduction confirming projected efficiency improvement)
Winter 2024-2025 operation:
  • Equipment operating reliably throughout heating season
  • No service issues during cold weather events
  • Tenant gas consumption December 2024 – February 2025: 64 therms vs. estimated 92 therms with old equipment (30.4% reduction)
  • Tenant satisfaction high; renewed lease for 2025 (continuing 4-year tenancy)

Commission cited this project as exemplary of “sensitive HVAC upgrades preserving historic character while improving building functionality” in their Q4 2024 historic preservation newsletter. Project documentation included in Commission’s reference library for future similar projects in the district.
Service relationship continuation:
Vanessa added this property to her multi-property maintenance contract documented in earlier WVC case study. Annual contract value increased from $1,800 (3 WVC triplex units) to $2,160 covering one additional unit. Annual fall furnace tune-up included for this Ogden property.
Word-of-mouth referrals from Historic Preservation Commission:
Commission newsletter coverage generated inquiries from two additional 25th Street District property owners considering HVAC upgrades for their restored historic properties. Both inquiries developed into successful projects through 2025.

Why This Case Study Illustrates Important Patterns

Historic preservation coordination requirements:
Historic district HVAC projects require coordination beyond standard installation: pre-project commission consultation, exterior modification approval, vent system planning that minimizes visibility, preservation of original building elements (brick chimneys, decorative interior features), photo documentation throughout project, post-completion verification. These requirements add 15-25% project complexity vs. non-historic equivalents. Specialized contractor experience essential for navigating commission processes effectively. Most general HVAC contractors lack historic preservation experience; specialized capability provides market advantage in historic districts.
Brick chimney preservation in atmospheric-to-sealed-combustion conversion:
Original brick chimneys served atmospheric venting for legacy gas furnaces. Modern sealed combustion equipment requires PVC venting through exterior wall (cannot use brick chimney for high-efficiency furnace exhaust). Preservation options: (a) demolish brick chimney (typically prohibited in historic districts; permanent loss of architectural element), (b) cap and seal chimney preserving structure (allows future use for fireplace or future equipment, maintains exterior architectural feature), (c) repurpose chimney as decorative feature only (acceptable preservation approach). This Ogden project used Option (b): cap and seal preserving structure for potential future use. Original brick chimney remains visible exterior architectural feature; no historic character lost.
Tin ceiling tile protection during interior work:
Original decorative tin ceiling tiles (common in early-20th century commercial-residential mixed-use buildings) require protection during nearby work. Damaged tiles essentially impossible to replace authentically; reproduction tiles widely available but lack historical authenticity. Protection methods: plastic sheeting barrier installed below tiles in work areas, dust control measures, careful handling of materials in work area, post-work tile inspection. Adds modest cost ($145 in this project) but avoids potentially expensive tile damage. Historic preservation projects require attention to these seemingly minor details.
Rental property HVAC equipment selection economics:
Rental property equipment selection differs from owner-occupied due to: (a) tenant typically pays utility costs, so efficiency benefits accrue to tenant not landlord, (b) equipment reliability more critical than peak efficiency (tenant turnover from equipment failures expensive), (c) installation cost vs. operating cost trade-off favors landlord more than owner-occupier, (d) tax depreciation provides ongoing benefit over 27.5-year residential rental property recovery period. Result: rental property HVAC typically targets mid-tier reliable equipment (Bryant 925SA, Carrier Performance, Heil N9MSB) rather than premium tier (Carrier Infinity, Bryant Evolution). This Vanessa Ogden project used Bryant 925SA mid-tier rather than premium equipment, consistent with rental property economics.
Multi-property contract value extension:
Vanessa’s expansion from 3-unit WVC triplex contract to 4-unit portfolio (adding Ogden 25th Street property) demonstrates value of contractor partnerships for multi-property investors. Single contractor relationship provides: consistent service quality across properties, predictable annual cost across portfolio, simplified administrative coordination, contractor familiarity with property-specific details (tenant patterns, equipment history, building characteristics), capital planning collaboration across portfolio. Property investors with growing portfolios benefit substantially from contractor partnerships vs. ad-hoc service calls.
Historic district neighborhood value impact:
Ogden 25th Street’s National Register Historic District designation creates property value premium of 15-25% vs. equivalent non-historic properties. Historic district maintenance and improvements directly support this property value premium. Owners maintaining historic character through proper restoration and sensitive modernization (like this HVAC project) contribute to district preservation while supporting their own investment value. Owners pursuing inappropriate modifications (visible vent terminations on facades, demolition of original elements, etc.) damage district value affecting all property owners. Coordination with Historic Preservation Commission preserves both individual property value and district-wide value.

Frequently Asked Questions

What approvals are needed for HVAC work in Ogden Historic 25th Street District?
Exterior modifications require Ogden Historic Preservation Commission approval. This includes: vent terminations on exterior walls, outdoor equipment placement, new exterior penetrations. Interior work generally doesn’t require commission approval. Pre-project consultation recommended to identify specific requirements for any project. Commission processes typically require 4-6 weeks from application to approval. Plan accordingly when scheduling projects in historic district. Our experience navigating commission processes facilitates effective project planning.
Can I convert from atmospheric to sealed combustion furnace in a historic district?
Yes, with proper coordination. Atmospheric-to-sealed-combustion conversion requires PVC vent through exterior wall replacing original chimney venting. Historic Commission approval addresses: vent termination location (typically prefer less-visible elevations), termination paint matching, original chimney preservation (typically cap and seal rather than demolish), exterior modification minimization. Most historic district HVAC projects successfully complete this conversion when properly coordinated; commission generally supports modernization that preserves historic character.
Why mid-tier 96% AFUE instead of premium 98% AFUE for rental property?
Rental property equipment selection economics differ from owner-occupied. Tenant typically pays utility costs in Utah rental market, so efficiency benefits accrue to tenant not landlord. Premium tier equipment ($4,000-6,000 more than mid-tier) costs landlord but benefits tenant. Mid-tier 96% AFUE captures full available rebates and tax credits, provides excellent reliability, lower upfront capital cost vs. premium tier. For owner-occupied homes with high heating consumption, premium tier may be appropriate; for rental properties, mid-tier typically provides better landlord economics. Bryant 925SA represents excellent mid-tier rental property selection.
How long do furnaces typically last in historic buildings?
Service life varies but historic buildings sometimes show exceptional equipment longevity. The 1985 Heil furnace replaced in this project provided 39 years service — well beyond typical 18-25 year residential furnace service life. Factors supporting longevity: (a) atmospheric (simple) equipment with fewer failure-prone components than modern condensing equipment, (b) limited annual operating hours (mild upper-floor unit with masonry thermal mass moderating heating demand), (c) regular preventive maintenance, (d) lack of significant operational stress events. Modern condensing equipment provides better efficiency but generally requires more maintenance attention; service life often shorter than legacy atmospheric equipment.
Is rental property HVAC eligible for IRA 25C federal tax credit?
Yes, with specific conditions. Federal IRA 25C residential energy efficiency credit applies to residential rental property when: (a) property is residential (not commercial), (b) equipment meets efficiency thresholds, (c) credit claimed by property owner (landlord) on their tax return. Credit amount: 30% of equipment cost, capped at $1,200 for furnaces, $2,000 for heat pumps. This Ogden project captured $600 credit (30% of $2,400 furnace cost). Coordinate with tax professional for specific application to rental property tax filing. IRA 25C provides meaningful tax benefit for landlords replacing residential HVAC equipment.
