Since 1967, Spencer has serviced commercial HVAC equipment across central Alabama.
We understand the difference between residential and commercial systems—commercial units run longer, handle higher loads, require different maintenance schedules, and demand faster response when they fail. We’ve replaced rooftop units (RTUs), installed variable refrigerant flow (VRF) systems, maintained multi-zone commercial systems, and gotten facilities back up and running fast when your customers arrive and the AC isn’t working.
Spencer Heating and Air holds Alabama License #13038 and carries comprehensive liability, workers’ compensation, and commercial bonding coverage.
Every commercial project is documented with detailed service records for your facility management team. We comply with building codes, EPA regulations, and industry standards for all commercial work.
When your commercial HVAC system fails, every minute of downtime affects your business, your employees’ productivity, and your customers’ experience.
We prioritize commercial repair calls during business hours. Call us and we’ll respond as quickly as possible to diagnose and restore operation.
Commercial systems that receive regular maintenance operate more reliably and last longer.
We offer maintenance contracts tailored to your equipment and facility needs. Planned maintenance visits catch wear before failures occur, extend equipment life, and keep your facility comfortable during peak business hours. Unexpected repairs are more disruptive and expensive than preventive maintenance.
Commercial buildings have different cooling and heating requirements than residences.
A single rooftop unit, a VRF multi-zone system, multiple independent units, or a hybrid approach might be right depending on your facility’s layout, usage patterns, and budget. We assess your application and recommend equipment that matches your actual needs—not oversized or undersized, but correctly matched.

Rooftop units are the most common commercial HVAC solution for single-story buildings with roof access. Self-contained heating and cooling in a single cabinet, installed on the roof with ductwork running through the building. We size, install, maintain, and repair RTUs from 3 tons to 25+ tons.
Our RTU services: load calculations for proper sizing, crane installation and rigging, electrical connections, ductwork integration, controls programming, and ongoing maintenance contracts.
Best For
Single-Story Commercial
Retail, offices, warehouses, and light industrial facilities with roof access.
VRF systems offer precise zone control, high efficiency, and the ability to heat and cool different areas simultaneously. One outdoor unit serves multiple indoor units with individual temperature control. Ideal for multi-tenant buildings, offices with varying occupancy, or facilities needing flexible comfort zones.
VRF advantages: energy efficiency, quiet operation, individual zone control, simultaneous heating and cooling, and reduced ductwork requirements.
Best For
Multi-Zone Control
Office buildings, multi-tenant spaces, and facilities needing flexible temperature zones.
Traditional multi-zone systems use a central air handler with zone dampers and multiple thermostats. Good for buildings with defined areas needing different temperature setpoints. We design, install, and service multi-zone systems with proper controls and balancing.
Multi-zone features: central equipment with distributed control, zone dampers for airflow control, multiple thermostats, and energy-efficient operation when properly designed.
Best For
Defined Zones
Buildings with distinct areas needing different temperature control.
Self-contained heating and cooling systems installed at ground level or on platforms. All components in one cabinet — compressor, evaporator, condenser, and controls. Easier maintenance access than rooftop units, good for buildings without suitable roof structure.
Packaged unit benefits: ground-level installation and service access, all components in one cabinet, available in gas/electric or heat pump configurations.
Best For
Ground Installation
Buildings without roof access or structural limitations for rooftop equipment.
Preventive maintenance keeps commercial systems running reliably and efficiently. We offer customized maintenance contracts with quarterly or semi-annual visits, priority response, and detailed service documentation. Maintenance prevents costly failures during business hours.
Maintenance includes: filter changes, refrigerant pressure checks, electrical testing, coil cleaning, bearing lubrication, and system performance verification.
Service Frequency
Quarterly/Semi-Annual
More frequent than residential due to longer operating hours and higher loads.
Commercial HVAC failures hit hard. We provide rapid response for commercial clients with experienced technicians and priority parts sourcing. Fast repairs minimize business disruption and get your facility comfortable quickly.
Rapid response: fast technician dispatch, priority parts sourcing, and work scheduling to minimize business disruption.
Response Time
Rapid Response
Priority response for commercial clients during business hours.
Professional assessment, customized solutions, and ongoing support. Every Spencer commercial project follows the same five-step process — from initial facility evaluation through long-term maintenance partnerships.
For new clients, we begin with a comprehensive facility assessment. We meet with facility management, tour the building to understand layout and usage patterns, evaluate existing HVAC equipment (age, capacity, condition), review maintenance records, and discuss comfort concerns or operational issues. We measure square footage, assess insulation, check ductwork condition if present, and identify special requirements (server rooms, medical facilities, kitchen exhaust, etc.). This assessment forms the foundation for maintenance contracts, equipment recommendations, or repair planning.
Based on the facility assessment, we develop a customized maintenance contract specifying visit frequency, services included, parts coverage, priority response times, and pricing. Commercial systems typically benefit from quarterly or semi-annual maintenance—more frequent than residential. Maintenance visits include filter changes, refrigerant pressure checks, electrical connection inspection, coil cleaning, bearing lubrication, and system cycling tests. We schedule visits during non-peak operational hours to minimize business disruption.
Our technicians arrive for scheduled maintenance visits with all necessary equipment and parts. We perform all specified maintenance tasks, document findings, and brief facility staff on any issues identified. For equipment nearing end-of-life or developing problems, we recommend replacement options and timelines. We monitor trends—gradual pressure loss, bearing noise, electrical issues—so you can plan equipment replacement before failures occur during critical business periods.
When equipment fails, we respond quickly with experienced technicians and stocked service vehicles. We diagnose the problem, assess whether repair or replacement makes sense, and execute the fix. We prioritize urgent commercial repairs. We work on your schedule to minimize disruption—whether that means scheduling follow-up before opening or installing temporary equipment while permanent repairs proceed.
If equipment replacement is needed, we assess options for your facility: rooftop units for buildings with roof access, wall-mounted or indoor equipment for others, VRF multi-zone systems for facilities needing flexible zoning, or hybrid approaches combining multiple equipment types. We develop a timeline for replacement—whether during low-usage periods, in phases to maintain partial operation, or as an immediate replacement. Installation includes all ductwork or piping modifications, thermostat integration, testing, and operational training for your staff.
Our maintenance members enjoy priority scheduling, consistent system performance, and the confidence that comes from knowing a trained professional is keeping an eye on their equipment throughout the year.
What’s Included In Our Maintenance Plan?
Hover over the section to see the full list. From retail stores to office buildings, condominiums to industrial facilities, Spencer provides commercial HVAC solutions tailored to your business needs.
Every commercial facility has unique requirements — operating hours, occupancy patterns, special ventilation needs, budget constraints, and comfort expectations. We assess your specific situation and recommend the right equipment, maintenance schedule, and service approach for your business.
Customer comfort drives sales. We install and maintain HVAC systems for retail spaces, ensuring consistent temperatures during peak shopping hours. Rooftop units, packaged systems, and multi-zone solutions available.
Productive employees need comfortable work environments. VRF systems, multi-zone controls, and energy-efficient equipment keep office spaces comfortable while controlling operating costs.
Owner and resident comfort depends on reliable systems. We service individual unit equipment, central building systems, and common-area HVAC for condominium associations and multi-unit lakefront buildings.
Lake Martin rentals and second homes need dependable comfort for every guest and a quick response when something goes wrong. We keep vacation properties and short-term rentals running with seasonal tune-ups, flexible scheduling, and prompt service between bookings.
Kitchen heat loads and customer comfort require specialized HVAC design. We handle the unique challenges of restaurant HVAC — high heat loads, ventilation requirements, and rapid temperature recovery.
Large spaces with high ceilings need specialized equipment. We install and maintain industrial HVAC systems designed for warehouse applications — high-capacity units with proper air distribution.
Healthcare facilities have strict comfort and air quality requirements. We understand the special needs of medical offices, dental practices, and professional service facilities.
Commercial systems are larger, more complex, and designed for longer operational hours. They often use rooftop units, multi-zone systems (VRF), or multiple independent units rather than single residential-style systems. Commercial equipment is rated for continuous operation, commercial electrical loads are higher, and maintenance requirements are more frequent. Commercial systems also involve more complex controls, occupancy sensors, and energy management systems.
Quarterly or semi-annual maintenance is typical, compared to annual for residential systems. More frequent maintenance is sometimes appropriate for equipment running 12+ hours daily or in humid climates where mold risk is high. We assess your equipment and recommend maintenance frequency. Regular maintenance prevents unexpected failures during business-critical periods.
Depends on square footage, insulation, windows, roof color, occupancy load, heat-generating equipment (computers, cooking, etc.), and local climate. Oversizing wastes energy; undersizing leaves you uncomfortable and unable to reach setpoint. We conduct a load calculation for your exact building to recommend correct capacity. A properly sized unit operates efficiently and performs reliably.
VRF (Variable Refrigerant Flow) systems offer excellent control, efficiency, and flexibility for multi-tenant or large commercial spaces. Different zones can heat or cool independently. Energy efficiency is higher than older systems. Cost is higher upfront, but operational savings and tenant flexibility often justify the investment over the system’s 15–20-year life. We assess your facility and help you decide.
Essential services: filter changes, refrigerant pressure verification, electrical connection inspection, coil cleaning, bearing lubrication, thermostat calibration, and system cycling tests. The contract should specify visit frequency, response times for urgent calls, parts coverage, labor coverage, and pricing. A good contract gives you predictable costs and priority service.
Varies based on equipment size and complexity, visit frequency, and what’s included in the contract — we quote upfront. Repairs outside the contract are additional. Maintenance costs are far less than unexpected downtime when equipment fails.
Often. If your existing ductwork is sound and your unit’s age permits, we can upgrade components—install more efficient refrigerant, add modern controls, replace the blower, or add accessories like humidity control. A complete system replacement is sometimes necessary if equipment is old, parts are obsolete, or efficiency gain justifies the cost. We assess your situation and recommend the most cost-effective path.
Call us right away at 256-373-3165. We’ll send a technician as quickly as possible. We work on your timeline to restore operation while minimizing business disruption. If repair takes time, we can discuss temporary equipment options or phased repair schedules. The faster you report the problem, the faster we can respond.
Regular maintenance keeps equipment operating efficiently (10–20% savings possible). Thermostat setpoints and scheduling can reduce unnecessary operation. Equipment upgrades to more efficient systems provide long-term savings. Ductwork sealing and insulation prevent energy loss. We assess your facility and recommend cost-effective improvements.
Manufacturer warranties vary (typically 1 year full, 5–10 years on compressor). Our service and installation labor carries a 1-year warranty. Extended warranties and service contracts provide additional coverage. We discuss warranty options during the equipment selection and installation process.
