You have just installed a brand new HVAC system. It is quiet. It is efficient. And it is backed by a manufacturer’s warranty. So it is tempting to think maintenance can wait.
But here is the truth. Skipping maintenance, even in year one, can lead to early system problems, higher energy bills, and voided warranty claims. In other words, new does not mean no care.
At Harold Brothers, we have helped building owners and facility managers protect their HVAC investments from day one with preventative maintenance programs that catch issues early and keep systems running at peak performance.
In this article, you will learn why even new HVAC systems need regular maintenance, what can go wrong if you skip it, and how to avoid early failures that cost you more in the long run.
New HVAC systems can fail early, not always because the equipment is bad, but because small issues can grow quickly if no one checks the system.
Preventative maintenance is not just a contractor recommendation. The U.S. Department of Energy’s Better Buildings Initiative highlights that preventative maintenance for commercial HVAC equipment plays a critical role in preserving efficiency, extending equipment life, and avoiding early system failures.
Here’s why that matters:
That means a “new” system can still run into problems that hurt performance, comfort, and your bottom line. For a complete step-by-step of what we check in routine service, see our HVAC preventative maintenance walkthrough
Here are the most common problems building managers face when they skip maintenance on new HVAC equipment:
Many warranties require proof of regular maintenance. If you don’t document service visits, a manufacturer might deny a claim. That can leave you paying for major repairs that should have been covered. Learn more in Commercial HVAC Preventative Maintenance vs Warranty
Even well-installed systems can have small setup issues:
If these aren’t corrected early, they stay hidden until they cause bigger failures.
Right after installation, construction dust and jobsite debris can still be in the air. That dirt gets into filters, coils, and fans and quickly affects performance. To see how dust and debris influence overall facility care practices, read Building Maintenance Practices for Commercial Facilities.
New systems are sold as efficient, but they only hit peak efficiency when they’re set up and tuned right. Without maintenance, your system may run harder than it needs to, which means higher monthly bills. See how HVAC maintenance can lower utility bills.
Modern HVAC systems have sensitive electronics and controls. A small issue that would be easy to fix early can turn into a part-failure or system shutdown if it’s never checked.
Even equipment manufacturers stress the importance of early maintenance. Mitsubishi Electric notes that regular HVAC maintenance helps prevent premature component failure, especially in modern systems with advanced controls and electronics.

Without routine checks, small airflow or programming issues can make tenants uncomfortable without you knowing why.
A professional HVAC maintenance visit does more than just a quick look. A licensed technician will:
According to ENERGY STAR, consistent operation and maintenance tasks like inspections, cleaning, and performance checks are among the most effective building operations and maintenance best practices for protecting HVAC efficiency and reliability over time.
By catching small problems early, maintenance keeps your system running safer, more reliably, and more efficiently.

A lot of owners rely on the manufacturer’s warranty and think that means they don’t need maintenance. But warranties usually only cover parts and only if you prove you maintained the system. Without that proof, even new equipment may cost you in repairs.
So instead of seeing maintenance as optional, think of it as protection for your warranty and your budget.
The best move is to start maintenance right away, even in the first year.
Here’s a simple, smart plan:
This kind of proactive care helps prevent:
You now know that new does not mean maintenance free. From early wear and tear to hidden installation issues, even the best HVAC systems can fail early without regular oversight.
Skipping maintenance may feel harmless in the first year, but it often leads to denied warranty claims, higher energy costs, and expensive repairs that could have been avoided.
So what actually gets done during those maintenance visits, and how does that protect your system?
