  • Fully-stocked trucks:

Our commercial trucks are stocked with a massive inventory of factory-authorized parts. We don’t just diagnose the problem; we usually have the component needed to fix it immediately.

  • 24/7 emergency response:

HVAC emergencies don’t stick to business hours. Neither do we. Our teams are on standby 24 hours a day, 7 days a week, ensuring that a breakdown on Saturday night doesn’t ruin your Monday morning opening.

  • Expert diagnostics:

Our NATE-certified technicians are trained on complex commercial systems, from Variable Air Volume (VAV) boxes to industrial-grade boilers.

These capabilities allow us to solve problems faster, allowing you to get back to business as usual without unnecessary delays or repeat visits.

Commercial Heating Installation & Replacemen

Is your aging HVAC system driving up your utility bills? We specialize in high-efficiency commercial heating installation. We help you select the right system for your square footage and usage patterns, whether that’s a robust rooftop unit (RTU) or a complex split system.

When you trust Allied with your installation, you benefit from:

  • Custom Design:

We ensure your ductwork and zoning are optimized for commercial loads, preventing hot/cold spots in your facility.

  • ROI Focus:

We help you calculate the energy savings of modern units to ensure a smart return on your investment.

Commercial Maintenance Plans

The most expensive repair is the one that could have been prevented. Our commercial heating maintenance programs are the best insurance policy for your facility, designed to catch small issues before they become system failures.

We offer flexible schedules (Bi-Annual or Quarterly) that include:

  • Safety & Performance Checks:

We inspect heat exchangers for cracks, calibrate safety controls, and tighten loose electrical connections that can cause intermittent failures.

  • Priority Service:

Maintenance agreement holders get front-of-the-line access during peak winter storms.

  • Compliance Assurance:

We ensure your systems meet all local safety and building codes.

With a proactive plan in place, you can budget for routine maintenance rather than constantly reacting to expensive, unexpected emergency repairs.

What Our Customers
Say About Us

We moved into a new house recently and Allied was recommended to us by my best friend.

We had them install a new humidifier and zone the system. On moving day (Friday) at 3 pm when we showed up we found the AC wouldn't shut off. I texted my tech with hopes of getting on the schedule for the following week since it was late Friday. He said someone would be there in 30 min. They stayed for 2 hours and fixed a faulty wire and it was all covered under warranty. Can't argue with customer service like that. Highly recommend if you want dependable folks that are very responsive.

We were extremely pleased by the service that Allied provided us.

Our A/C went out over the 4th of July we knew we needed a new system installed asap (we knew it was on its last leg). We contacted them and two other companies for comparison quotes. Allied was out here first thing July 5th to assess and provide a quote. In the end we decided to go with them. They were professional, thorough and very detailed in options and quotes.

Moved into the neighborhood and Allied HVAC had been recommended from my brother to replace both our furnace and ac unit.

Very professional from the start with a quote from Chris B. in sales which lead to an install date of my choice. On the day of the installation Jeff and Jackson arrived right on time as requested. The installation was prompt and done in a timely matter, and it they explained exactly what needed to be done from start to finish.
