Who we service

What we offer

We offer complete service & installation of all commercial HVAC equipment, ductwork, gas piping and ventilation equipment including:

Rooftop systems like the name suggests, is one unit that is located on the roof and is ducted to run heat or cool air throughout a space. They are a flexible way to offer heating and cooling to various sized buildings.  Rooftops can serve one large area or a building with many different zones.  Fresh outside air is mixed with return air from inside the building then filtered, conditioned (heated or cooled) and supplied back into the building.  Rooftop systems are an easy to maintain, energy efficient choice for any space.

Standard Make-up air units are designed to provide fresh air that is heated or cooled to a space to offset air that is being exhausted by other mechanical means.  For example, a manufacturing plant that has exhaust fans to remove smells will need a make-up air unit to provide new air into the building or the building will become pressurized.  Make-up air units depressurizes the space.

Newer make up air units are available to be installed with heat pumps.

Water conducts thermal energy quickly and retains heat longer then air, which makes boilers more energy efficient.

A boiler is used to heat a liquid as it passes through it. Boilers can be used for many purposes such as hydronic perimeter heating, in-floor heating, fan coil units, domestic hot water, and for process applications.

Tankless boilers can be used to replace larger conventional boilers by being installed in tandem to make up capacity required.

Tankless water heaters are a cost-effective solution to a wide variety of commercial applications.  Building owners will appreciate the efficiency, reliability and durability of tankless water heaters over outdated tank systems.  Space saving design gives flexibility in installing, and always deliver hot water on demand!

Water source heat pump systems are one of the most efficient, environmentally-friendly systems available for heating and cooling buildings. High-efficiency, self-contained units are available in a variety of sizes and configurations and can be placed in virtually any location within a building. Each water source heat pump system responds only to the heating or cooling load of the individual Unit it serves. This permits an excellent comfort level for occupants. Commercial water source heat pumps can be applied to geothermal closed-circuit or open-well loops, or on a traditional boiler/tower loop system. These systems offer benefits ranging from low cost installation to the highest energy efficiency available in the market today.

Due to the amount of heat generated by computer equipment it is essential to have a properly designed unit for a server room, depending on the size and cooling required a specifically designed unit offers year-round cooling & humidity control.  In some cases, a ductless split air conditioning unit designed to cool in winter will do the job.

Indoor air pollution is bad for business, it is a likely cause of employees being off sick or reduced work performance.  There are three basic strategies to improve indoor air; source control, improved ventilation and air cleaners. At A1 we have a great selection of indoor air quality products that can help keep buildings safe and healthy for everyone.

Get ahead of future problems before they happen. Protect your HVAC investment and business by pairing your system with a scheduled maintenance plan. Your system will run more efficiently and problem-free for a longer period of time, with less hassle for you.

Benefits of a scheduled maintenance plan:
