Why choose our All-Commercial Division for your business HVAC installation, maintenance, and repair needs?
Modern commercial heating, ventilation, and cooling equipment are typically part of a highly integrated “HVAC” system that demands expertise across plumbing, electricity, ductwork, thermostats, electronic digital controls, building codes, environmental regulations, and more. So minimally, the Madison commercial HVAC company you hire must have knowledge, experience, and resources across a spectrum of skills, technologies, and even legalities.
We simplify the complicated.
As part of our All-Commercial Division, our HVAC technicians are fully backed by our commercial electricians and commercial plumbers. This means that we have licensed commercial plumbers and commercial electricians immediately available should your situation require them, thus avoiding the extra time, cost, and complications inherent to securing subcontractors — especially on short notice or in emergencies.
And our depth of resources does not stop there.
We have complete ductwork fabrication capabilities, including mobile equipment that enables us to build custom ductwork quickly and easily onsite at your location as needed. And when you additionally consider our full-time air-conditioning and air-quality specialists, it becomes evident that All Comfort Services is your most comprehensive resource for HVAC system repair in Madison.
With our up-front pricing, you’ll know your exact costs before we begin work at your business.
Unlike other Madison commercial HVAC contractors, we do not charge by the hour. You will always know your exact cost before we begin your work. With over 44 years of experience serving Madison and Dane County, we can accurately assess how long your project will take and what materials it will require. This allows us to give you a firm price rather than billing you by the hour—no matter how long it ultimately takes us. This ensures you there will be no hidden costs or surprise expenses.
We will arrive at your business with what you need, ready to work, and have you up & running ASAP.
Our HVAC electricians, plumbers, and technicians all drive fully stocked trucks; and they know from years of experience what will most likely be required to quickly complete your installation or repair. This minimizes the need to fetch parts, helping us realize economies and efficiencies that we pass on to you in the form of relative value and speedy service. Depend on All Comfort Services for all your commercial plumbing, installation, maintenance, and repair needs, including but not limited to:
Central air-conditioning units—both rooftop and pad-mounted
As part of your commercial HVAC system, a properly designed and installed commercial central air-conditioning system does more than simply control indoor air temperature(s). It also controls humidity and minimizes allergens such as pollen and dust.
It’s crucial that the compressor for your commercial central air-conditioning system be correctly sized. One that’s too big for the intended space will “short cycle,” turning itself on and off excessively so that interior spaces are alternately too cold and too warm.
Ductwork must be efficiently configured. E.g., a typical 900 bend in round duct presents as much resistance to airflow as an extra 12 feet of length! So, less turns mean more energy efficiency. Also, size and shape greatly affect noise. Low-frequency rumble from commercial HVAC systems is a health concern known to negatively affect workplace concentration and efficiency.

factors affecting your commercial central air-conditioning system.
Boilers & Furnaces
As an integral part of your commercial HVAC system, your furnace or boiler must be considered in relation to your central “AC” equipment along with the system by which heated or cooled air gets distributed throughout your commercial space: e.g., ductwork, radiators, radiant floor systems, etc.
Furnaces burn gas or oil—or in some cases use only electricity—to heat air and “force” it by way of fans and ductwork throughout your building. Hence commercial furnaces are often part of a commercial “forced-air” heating system.
Commercial boilers provide either hot water or steam that is distributed by pipes to radiators. Alternatively, hot water (but not steam) can be sent to baseboard radiators or radiant floor systems.
Commercial steam boilers operate at higher temperatures than commercial hot water boilers and thus tend to be less efficient. Furnaces that heat purely with electricity have the advantage of no heat-loss through a chimney, but electricity is a more expensive fuel than either gas or oil. So which is best?
High-efficiency versions of all types of furnaces and boilers are nowadays manufactured. Your existing commercial HVAC equipment must be taken into account. So steam might be best-suited to one kind of commercial building; hot water for another; while a gas, oil, or all-electric furnace might serve best elsewhere.

HVAC pneumatic and electronic controls
The simplest HVAC pneumatic controls use only compressed air to control the flow of conditioned air by opening or closing dampers. However, most HVAC pneumatic controls that are still seeing duty in commercial applications are integrated with electric switches and electromechanical relays.
Although pneumatic control systems (sometimes decades old) are still common in many older buildings, HVAC electronic controls are nowadays exclusively specified in commercial construction and renovations.
This is because HVAC electronic controls incorporate highly-accurate and relatively low-cost digital microprocessors to better meet today’s stricter energy-cost expectations and environmental concerns. In fact, it’s unlikely that a modern-day commercial HVAC system could be built to meet federal, state, and local regulations using only pneumatic controls.
Beyond greater accuracy, less maintenance, and lower cost, today’s HVAC electronic controls can even be accessed by off-site Web browsers. Managers needn’t be in the same building as the HVAC equipment, and a single operations center can monitor multiple buildings.

Water-source heat pumps
Is their money buried beneath your commercial building?
Underground temperatures tend to be warmer than the surrounding air in winter and cooler than it in summer. A water-source heat pump—also known as a geothermal heat pump or ground-source heat pump—takes advantage of these relatively moderate temperatures that lie beneath your commercial building.
Heat can be extracted from an underground water source, no matter how cold. A water-source heat pump supplements wintertime heating by extracting that heat and transferring it into your building.
The process can be reversed in the summertime. The water-source heat pump extracts heat from your building and transfers it to the ground, which is less expensive than air conditioning it.

Commercial ice machine installations require plumbing, electrical, and even HVAC expertise. Our All Commercial division offers all three—and more.
The water source must be able to deliver 5 gallons-per-minute and have a dedicated shutoff valve within 6 feet. Commercial ice machines less than 1300 lbs require a 3/8-inch supply line, or a ½-inch supply line if at or above that weight. Commercial ice machines generally require a floor drain within six feet. It should have an approximate ¼-inch drop for every 12 inches of pipe and be properly flanged as to not present a tripping hazard.
Most 110VAC commercial ice machines require 20-amps. Some 220VAC and some 3-phase machines require 30-amps. The circuit must be dedicated in all cases.
Air circulation around your commercial ice machine must be adequate to prevent “hot spots.” The ambient temperature in must be maintained between 450 and 950 Fahrenheit—especially in challenging industrial environments.

Coolers & Freezers
Commercial cooler or freezer installations require plumbing, electrical, and even HVAC expertise. Our All Commercial division offers all three—and more. Below is a partial list of concerns:
One of your first considerations is determining whether your particular installation requires a remote condensing unit. The job of any condenser is to extract heat. Allowing it to “dump” that heat into your commercial space can have significant consequences—perhaps good in the wintertime but not-so-good in warm weather. Managing that heat to best effect requires the advice & counsel of an HVAC expert.
In almost all cases your commercial cooler or freezer will require a dedicated circuit providing at least 20 amps at either 110VAC or 220VAC. Some 220VAC and some 3-phase machines will require higher amperage. Any wiring inside your cooler or freezer must meet watertight codes for commercial installations
Some condensers are water-cooled and thus require both supply and return lines equipped with isolation valves to separate the coolant from your building’s potable water.
