How much does HVAC installation cost?

Ranges widely by equipment type, efficiency tier, and installation complexity. AC-only installation: 14 SEER2 $6,485-$9,485, 17 SEER2 $8,485-$12,485, modulating 20+ SEER2 $11,485-$16,485. Furnace-only installation: 80% AFUE $4,285-$6,485, 96% AFUE $6,285-$9,485, modulating 98% $8,485-$13,285. Full-system paired AC + furnace: $12,485-$22,485 depending on efficiency tier. Dual-fuel (heat pump + gas furnace): $14,485-$24,485. Ductless mini-split: $4,485-$8,485 per zone. Site visit with load calculation typically required for accurate quote; free site visits within Columbia proper.

What's the difference between single-stage, two-stage, and modulating equipment?

Single-stage equipment runs at 100% capacity when it runs. Two-stage runs at either 60-70% capacity (low fire or partial cooling) or 100%. Modulating equipment ramps continuously between about 30% and 100% capacity based on demand. Higher staging tiers produce better comfort (steadier temperature, less cycling), better dehumidification (longer runtime), and better efficiency (lower load conditions run at lower capacity). Cost scales up: single-stage cheapest, modulating most expensive. For most Columbia residential, two-stage represents good balance of upfront cost and comfort improvement. Modulating equipment shines in tight-envelope newer construction and in homes where precision comfort matters.

Do you handle the federal 25C tax credit paperwork?

Yes. Federal 25C residential energy tax credit provides $600 for qualifying gas furnaces (95% AFUE or higher) and $2,000 for qualifying heat pumps. PolarCore provides the required documentation (Manufacturer's Certification Statement, invoice showing qualifying equipment, installation date) that customers submit with their federal tax return using IRS Form 5695. The credit is a dollar-for-dollar reduction in federal tax liability, not a refund, so it applies against taxes owed rather than being paid out directly. Consult a tax advisor for specific guidance on your tax situation.

How long does a typical HVAC installation take?

Standard full-system installation (AC + furnace replacement in existing residential): 6-10 hours on a single day for most installations. More complex installations (major ductwork modification, zoning, ductless multi-zone with 3+ heads) can take 1-3 days. Heat pump installations similar to full-system timing. Boiler installations 8-16 hours depending on complexity. Ductless single-zone installations 4-6 hours. PolarCore schedules installations to minimize household disruption; equipment removal and new equipment delivery coordinated for single-day completion where possible.

Do you coordinate the permit process?

Yes. Installations requiring permits (equipment replacement, gas line modification, ductwork modification, new construction) are permitted through the City of Columbia Mechanical Contractor License (#MCL-2016-04187) or Boone County Contractor Registration (#BCR-16-2847) as appropriate. PolarCore handles permit application, inspection coordination, and permit closeout. Permit fees typically included in installation quote; permits are transferable to homeowner for property records.

HVAC Installation Services in Columbia, Missouri

Correctly-installed HVAC equipment runs efficiently, reaches its rated service life, and stays under warranty. Incorrectly-installed equipment produces comfort complaints, elevated energy bills, premature failures, and voided warranty claims — regardless of how good the equipment itself is on paper. PolarCore’s installation work applies ACCA Manual J load calculations for equipment sizing, ACCA Manual S for equipment selection, ACCA Manual D for ductwork design, ASHRAE 62.2 for ventilation, and 2018 IMC/IFGC for code compliance — not “eyeball” sizing based on square footage rules of thumb. Installation quotes include the calculations that support equipment selection so customers can see how the recommendation was reached.

Installation Services Covered

HVAC Replacement — full-system replacement of aging or failed equipment with new AC + furnace, heat pump, or dual-fuel installations. Includes Manual J load calculation, Manual S equipment selection, warranty registration, and 25C tax credit documentation where applicable.
Ductless Mini-Splits — Mitsubishi and Fujitsu ductless systems for room additions, garages, shops, historic homes without ductwork, and zoning within existing homes. Multi-zone systems with single outdoor unit and 2–5 indoor heads.
Zoned HVAC — ductwork zoning with motorized dampers, dedicated thermostats per zone, and bypass configurations. Best for multi-story homes with temperature differential between levels.
Smart Thermostats — ecobee, Honeywell T10, Trane XL824, Nest installations with communicating HVAC integration, humidity control, and remote access.
Thermostat Repair — thermostat failure diagnosis, wiring inspection, and thermostat replacement for standard 24V or communicating installations.
Air Handler Services — air handler replacement, blower motor replacement (PSC and ECM), evaporator coil replacement, and air handler cabinet modification for filter cabinet installation.

Design Standards Applied to Every Installation

ACCA Manual J Load Calculation

Manual J calculates the actual heating and cooling load for the specific building based on: house dimensions, insulation R-values, window U-values and orientation, air leakage rate, internal loads from occupants and equipment, and Columbia climate design conditions (ASHRAE 99% winter 4°F, 1% summer 91°F DB / 76°F WB). This produces a specific BTU/hr requirement rather than square-footage rule-of-thumb sizing. Manual J calculations are included in installation quotes; skipping this step is one of the primary causes of oversized equipment that short-cycles, dehumidifies poorly, and reaches end of service life prematurely.

ACCA Manual S Equipment Selection

Manual S selects specific equipment models that match the Manual J load calculation. Selection considers: sensible and latent capacity separately (not just total capacity), efficiency ratings (SEER2 for cooling, AFUE for furnace, HSPF for heat pump), staging capability (single-stage, two-stage, modulating), and integration with any existing equipment.

ACCA Manual D Ductwork Design

Manual D calculates ductwork sizing to deliver the correct CFM to each register at the correct static pressure. Existing ductwork gets evaluated during installation quotes: existing ductwork undersized for new equipment air handler requires modification; existing ductwork oversized creates its own problems with low velocity and poor distribution. Documented duct evaluation is included in installation quotes.

ASHRAE 62.2 Ventilation

Whole-house ventilation requirements from ASHRAE 62.2 apply to newer construction and to installations where existing infiltration doesn’t meet ventilation targets. Mechanical ventilation options (bath fan runtime, dedicated ventilation fan, ERV/HRV) evaluated based on specific installation.

2018 IMC/IFGC Code Compliance

City of Columbia adopts 2018 International Mechanical Code and International Fuel Gas Code. Installations comply with venting requirements, clearance requirements, combustion air requirements, gas line sizing, and permit and inspection requirements per 2018 code editions.

Warranty and Documentation

Installation includes:

Manufacturer warranty registration at completion (typical 10-year parts, 1–5 year labor depending on brand and equipment tier)
PolarCore installation warranty — 2-year labor warranty on installation workmanship
Documentation package including equipment nameplates, warranty registration, load calculation, permit documentation, and startup measurements uploaded to customer ServiceTitan record
25C tax credit documentation (federal residential energy tax credit) where applicable — $600 for qualifying gas furnaces, $2,000 for qualifying heat pumps
Ameren MissouriSaves rebate documentation where applicable
Missouri Show-Me Green Sales Tax Holiday (April 19–25) coordination for installations timed within that window

Financing Options

PolarCore offers third-party financing through Wells Fargo and Synchrony Bank on installation work. Common financing scenarios: 0% APR for 12–18 months on qualifying installations (customer must qualify with credit approval), same-as-cash 6–18 month promotional periods, and multi-year fixed-rate financing at competitive rates. Financing applications processed on-site or online with approval typically same-day. Federal 25C tax credit ($600 furnace, $2,000 heat pump) and Ameren MissouriSaves rebate can be applied against the financed amount to reduce total cost.
