Business Partners Program

We’ll provide a carefully tailored HVAC solution that matches your facility and the business you conduct within those walls. Our program hinges on predictive maintenance to help prolong equipment life, and even spot and solve minor issues before they grow into major problems.

Commercial indoor air quality

Indoor Air Quality (IAQ)

If you’re wondering whether your indoor air could be cleaner, fresher, and safer, you’re not alone — indoor air quality is at the top of everyone’s mind these days. The good news is that Haller offers a variety of additions, upgrades, and holistic solutions for better air.

Commercial Heating and Cooling Products and Systems

Knowing the system that suits your facility is the first step — outfitting it properly comes next.



We can help you choose and install a water-cooled chiller or air-cooled chiller to deliver the cool air you need with efficient, quieter operation.

Air Handler

Rooftop Units

A packaged rooftop unit (or RTU) is great for both smaller and larger commercial operations. We can help repair or install a unit for yours.

Ductless system

Mini Splits

No ductwork? No problem! When central air and heat isn’t an option, mini splits are a great solution. We can help you get the heating and cooling you need in each room.

VRF System

VRF Systems

Variable refrigerant flow or VRF systems use multiple indoor units and one outdoor unit. We can help install or repair each of these devices.

Building Automation


HVAC controls help focus efforts to improve efficiency. Haller offers full control and monitoring capabilities for your HVAC system.

Heat Pump

Heat Pumps

Moving heat outside in the summer and drawing it inside in the winter, heat pumps are excellent all-round HVAC devices for buildings.

Cooling Icon

Air Conditioning

Whether your building uses air ducts or not, air conditioning for your business is important to ensure comfort and to control humidity. We can help with any type of AC system.


Heating Systems

From radiant heating to geothermal, we can identify the right candidate for your building and your budget — or work to improve what you already have in place!

Gas Piping

Gas Piping

We understand gas pipe installation regulations, and our team can run new piping, repair older piping, or replace your gas piping altogether.

Hydronic system


A hydronic system heats water and runs it through a sealed system to heat an area, which can be more efficient than air-based heating.



Using steam to heat an area, a boiler is a good choice for a larger building. We work with top brands of boilers that save you energy and money.
