If you own a business in southeast Michigan, we’re the experts you should call to develop your industrial cooling and heating design plans, to install and service your commercial heating / ventilation / air conditioner systems; to expand your current capacity; to adjust, repair, or replace your existing heating and cooling systems; and to give you excellent customer service in the process.

We’re known for our prompt and knowledgeable service and our ability to respond to your needs.

You’ll be our valued A & B customer and we’ll look after all your commercial HVAC needs. We consider ourselves a member of your company’s team, working together with you to protect the investment you’ve made in your HVAC systems. You can count on us to:

  • Install your HVAC equipment so it performs reliably

In short, when it comes to the HVAC systems you use in your business, we want you to consider us your partner. We know you will appreciate what we can do.

We’ll Install Your New Commercial Heating or Cooling System

When your current equipment is ready to be replaced, A & B will remove it and install the next generation of equipment in its place. Coordinating the removal of the old with the delivery of the new, our technicians are trained to:

  • Remove existing mechanical systems, HVAC duct work, and piping

  • Assemble, install, and operate hydronic, gas, or oil-fired boilers and heat pumps

  • Install electrical, pneumatic, and electronic assemblies, controls, and heat distributing units

  • Adjust for humidity and temperature control

  • Complete the welding, wiring, and placement of pipes, tubes, fittings, and meters

  • Complete all work in accordance with federal and state regulations related to environmental protection and safety

Once we’ve completed the installation of your new commercial HVAC systems, our technicians will start it up, run it, measure its output, adjust it, and ensure that it’s operating at or above the manufacturer’s design specifications. We put it in and we stay until we’re sure it’s running right. We’ll stop back later, too, to make the minor adjustments it takes to get your system operating at peak efficiency. You can count on A & B to get your new heating and cooling systems in place and make sure they run as they should.

We’ll Respond Promptly to Your Emergency, with Speed and the Right HVAC Supplies

When you call us for emergency repairs, we’ll prioritize your call to the top of our list. A & B’s fully equipped fleet of vehicles stocked with ample parts inventories can be dispatched at a moment’s notice to address your emergency. We are able to communicate with our technicians on the road. We use a computerized tracking system customized for our business to adjust workloads, reprioritize assignments, access your company’s service history and equipment needs, and readily retrieve the right parts for your job.

Why should you wait for someone else while you close down your business, send your employees home, and lose a day’s work? For your commercial heating or cooling emergency, call us at A & B. We’re right around the corner.

We’ll Do Regular HVAC Service Maintenance to Ensure Reliable Functioning

A & B encourages regular HVAC service maintenance for your commercial HVAC systems, to prevent outages and malfunctions and to extend the life of your equipment. When you join one of our preventive maintenance programs, we’ll visit regularly to make sure your equipment is maintained according to the manufacturer’s recommendations. We’ll provide you with a planned HVAC service maintenance schedule that covers the life of your equipment. On the day we’re scheduled to visit, we’ll call you to let you know we’re on our way. When we arrive, we’ll thoroughly check every appliance covered by the agreement, using our comprehensive HVAC systems checklist as our guide. Among other things, we’ll test for and repair leaks; drain lines; check fluid and lubricant levels; test for carbon monoxide; lubricate motors and bearings, check relays and contactors, remove worn hoses and belts and install new ones; tighten loose parts; clean dirty areas, and make minor repairs. We’ll assess potential problem areas and make recommendations on how to address them. We’ll enter everything into our computerized database, so it becomes part of your company’s history at A & B. We’ll provide you with a computer-generated checklist that shows what we’ve done and what we’re recommending.

As a valued A & B client, you’ll find that HVAC service maintenance pays for itself in:
