Which service category should I use for a general HVAC problem?

Start with either the Cooling Services or Heating Services page depending on which system is failing. If both cooling and heating are affected (typical for controls, thermostat, or blower failures), the Maintenance Services page covers general diagnostic work. If the problem is air quality or humidity rather than temperature, the Indoor Air Quality Services page is the right entry point. For any emergency — no heat below 40°F outdoor, no cool above 88°F outdoor, gas smell, CO alarm — call the emergency line directly at (573) 615-6659 rather than working through the category pages.

Does PolarCore handle both residential and commercial work?

Yes. Residential work covers all six categories above at single-family and small multi-family scale. Commercial work covers the same categories at building-scale, primarily through the commercial rooftop unit and service contract programs. The Commercial Services page describes the specifics of commercial HVAC installation, maintenance, and rooftop unit work. Buildings above roughly 25,000 square feet, industrial process cooling, or specialty applications (data centers, cleanrooms, cold storage) fall outside PolarCore's current scope and are referred to specialized commercial mechanical contractors.

What's the difference between installation and specific replacement services like AC installation or furnace installation?

The Installation Services page covers general full-system replacement work and installations that span multiple categories (full replacement of both furnace and AC together, ductless mini-split systems, zoned HVAC, thermostat and air handler work). The specific service pages under Cooling and Heating cover single-category installations — AC installation alone, furnace installation alone, heat pump installation alone. Full-system replacements often route through the general Installation page because they cover both heating and cooling in a single project.

Can I schedule multiple services in a single visit?

Yes, and this is common with maintenance plan customers where a spring tune-up visit might combine cooling system prep, humidifier service, and air filter replacement in a single appointment. Diagnostic and repair calls that reveal multiple issues (a failed capacitor plus a bad contactor plus a clogged condensate drain) get itemized into a single quote with each issue addressed in one visit whenever parts are on the truck. Combining service categories saves the customer both trip fees and time.

Do you charge different rates for different service categories?

The base diagnostic service fee is $95 across all categories. Repair labor rates are consistent across residential service categories. Commercial service rates differ slightly due to equipment access, code compliance overhead, and the specialized documentation commercial customers require. Installation pricing is quoted individually based on equipment selection, Manual J load calculation results, permit costs, and any ductwork modification required. Emergency after-hours calls carry higher trip fees ($195 weeknight, $265 weekend/holiday/overnight) disclosed at dispatch.

HVAC Services for Columbia and Mid-Missouri

PolarCore’s residential and light-commercial service catalog covers six categories that collectively handle every HVAC need in Boone County housing stock — from a $174 stuck-pressure-switch repair on a 1928 Old Southwest bungalow to a $22,000 Mitsubishi Hyper-Heat multi-zone conversion in a Bluff Creek Estates tight-envelope build. This page is the top-level index. Each category below links to the more detailed service pages that describe specific work: individual repair categories, installation types, indoor air quality equipment options, and maintenance programs. Whether the request is a same-day no-heat call, a second-opinion diagnostic on a competitor’s five-figure quote, or a full-system replacement following an ACCA Manual J load calculation, the entry point is the Corona Road office at (573) 615-6659.

Why the Same Six Categories Cover Every Boone County HVAC Need

The Columbia housing stock spans nearly 130 years — from 1905 East Campus balloon-framed bungalows to 2024 Bluff Creek Estates builds hitting IECC 2018 ACH50 numbers under 4.0. The commercial building inventory spans from 1898 downtown storefronts to 2020s LeMone Industrial Boulevard warehouses. Across that range, HVAC work reduces to six functional categories: cooling (making warm air cold), heating (making cold air warm), indoor air quality (making air itself cleaner and drier), maintenance (keeping working equipment working), installation (replacing failed or obsolete systems), and commercial (which spans all of the above but at building-scale rather than room-scale). Every specialized service on the site — capacitor replacement, gas line installation, UV coil treatment, zoned ductwork — is a subcategory of one of these six.

Cooling Services

Columbia’s humid continental summer creates cooling challenges most Midwest HVAC installers underestimate. July dewpoints at Columbia Regional Airport (KCOU) run 70–73°F, which translates to grain loads exceeding 110 grains of water per pound of dry air on typical July afternoons. Oversized cooling equipment short-cycles before coil temperatures drop far enough to condense that moisture, leaving homes cold and damp. Under-sized equipment runs continuously without maintaining setpoint. Correctly sized R-454B compliant equipment matched to an ACCA Manual J load calculation delivers the comfort the customer actually wants.

PolarCore’s cooling services include AC installation, AC repair, AC tune-up, capacitor replacement, compressor repair, refrigerant recharge and leak repair, evaporator coil repair, and the rare swamp cooler service for the small number of legacy evaporative cooling installations still operating in the region. See the full cooling services page for details on each.

Heating Services

The 2021 IECC places Boone County in Climate Zone 4A — mixed-humid, not mild. Annual heating degree days at KCOU: approximately 4,800. The ASHRAE 99% winter design temperature: 4°F. Central Missouri catches periodic January arctic outbreaks paired with freezing rain — the January 2007 ice storm event left 100,000+ Ameren Missouri customers without power for over a week. Heating equipment sized and specified for this climate has to handle those extremes without failing during them.

PolarCore’s heating services include furnace installation, furnace repair, furnace tune-up, heat pump installation (including cold-climate variable-capacity systems rated for 100% capacity at 5°F), heat exchanger repair (with borescope diagnostic first, not sales-pitch replacement), boiler installation, boiler repair, and gas line installation for both natural gas and propane service. See the full heating services page for details.

Indoor Air Quality Services

Central Missouri’s humid continental climate creates specific indoor air quality challenges: summer latent loads that oversized cooling can’t dehumidify, winter dry-air conditions when infiltration drops interior humidity below 25%, McBaine well field water at 20–24 grains per gallon that scales humidifier and dehumidifier equipment on shortened service intervals, and PM2.5 loading from Missouri agricultural burn seasons and occasional summer smoke events. Standard filtration doesn’t address any of these adequately.

PolarCore’s indoor air quality services include whole-home MERV 13 media filtration retrofits, HEPA bypass filtration for households with documented asthma or COPD, whole-house dehumidification (Ultra-Aire, Aprilaire), steam and bypass humidification with hardness-corrected service intervals, UV-C coil treatment for evaporator biofilm, HRV/ERV ventilation for tight-envelope post-2015 builds, carbon monoxide testing, and air filter replacement programs. See the full indoor air quality services page for details.

Maintenance Services

Preventive maintenance is the single most cost-effective HVAC service category. A properly maintained system routinely reaches or exceeds its rated service life; a neglected system fails 3 to 5 years earlier and often catastrophically. PolarCore’s maintenance approach documents every visit with photos, meter readings, and spec-comparison reports uploaded to the customer’s ServiceTitan record — documentation that supports warranty claims, insurance disputes, and property disclosure at sale.

PolarCore’s maintenance services include HVAC tune-ups (twice yearly for standard forced-air systems), HVAC inspection reports for real estate transactions and insurance claims, 24/7 emergency HVAC repair, and structured maintenance plans covering roughly 640 residential accounts and 47 commercial contracts. See the full maintenance services page for details.

Installation Services

Full-system installation is the largest single-project category PolarCore handles. Every installation starts with an ACCA Manual J load calculation, then Manual S equipment selection, then Manual D duct verification if existing ductwork is being retained. Equipment sourced through authorized manufacturer distribution channels, permits pulled through the applicable building code authority, warranty registered on installation day, 30-day post-installation commissioning return included. No steps skipped.

PolarCore’s installation services include full HVAC replacement, ductless mini-split installation, zoned HVAC installation, smart thermostat installation, thermostat repair, and air handler services. See the full installation services page for details.

Commercial HVAC Services

Commercial HVAC work in Columbia spans professional buildings along Stadium Boulevard, retail along Broadway and Providence Road, medical and dental practices near Boone Hospital Center, and light-industrial in the LeMone Industrial Boulevard corridor. Equipment is typically rooftop packaged units (Trane Precedent, Carrier 48HC, Rheem RGEDZL Series) with economizer sections for outdoor air ventilation sized to ASHRAE 62.1 for the occupied load.

PolarCore’s commercial services include commercial HVAC installation and repair, quarterly commercial HVAC maintenance visits, commercial rooftop unit installation and replacement, and structured service contracts with priority dispatch and equipment aging documentation for capital planning. See the full commercial services page for details.

What Every Service Call Includes

Regardless of category, every PolarCore service call includes: on-meter diagnostic measurement (never visual-inspection-only), photographic documentation uploaded to the customer’s ServiceTitan record before the technician leaves the property, written diagnosis with recommended-repair estimate provided before work begins, permit filing through the applicable municipal building code authority for any installation work, warranty registration with the equipment manufacturer on installation day, and a 30-day post-installation return visit for commissioning verification on new installations. The consistency is deliberate. Diagnostic discipline that changes based on the type of call is not diagnostic discipline.
