5 Signs Your Commercial HVAC Needs Replacing

5 Signs Your Commercial HVAC Needs Replacing

Your company’s HVAC system is a critical component of your business. Not only does it keep employees and customers comfortable, it helps protect products and computer equipment from excess moisture. If your system isn’t working right, here’s how to know if you need it replaced instead of repaired.

5 Most Common Indicators You Need New Commercial HVAC

1. Your System Is Making Strange Noises 

One of the most common signs that any HVAC system isn’t working, commercial or otherwise, is if it makes odd sounds when it runs. Grinding, banging, screeching, or rattling can mean that internal parts are loose or are rubbing together, causing friction.

This is especially true if you have your system serviced and still hear strange sounds when it turns on. In this case, replacement is usually the most cost-effective solution.

2. Your Business Experiences Uneven Temperatures or High Humidity

Are temperatures inside your building different when you move between different areas? You might notice that sales employee offices are too hot while the sales floor is chilly, or vice versa. This is a sign that your HVAC system isn’t performing like it should. While having it repaired may help, it’s also a good idea to consider a more efficient system like ductless.

3. Your Energy Bills Keep Going Up

If your company’s electric bills continue to rise even without increased HVAC use, your system could be wasting energy. In fact, the Department of Energy estimates that up to 30% of energy used to heat or cool your business could be lost due to leaky or thin ductwork. If your system is older, these losses could be even higher. Replacing your existing system with a ductless mini-split is a great way to eliminate energy waste altogether.

4. Your System Needs Frequent Repairs

Do you have to keep repairing your system every season to make sure it works right? Chances are, this pattern will continue until you have your HVAC unit replaced. Replacing it with a standard central unit is less energy efficient than ductless, and you’ll still lose heat or AC through the ducts when it runs.

Alternatively, a commercial ductless system is easy to maintain and generally needs fewer repairs over time than a standard system. Plus, you don’t have to have your ducts cleaned or sealed every couple of years.

5. You Haven’t Gotten a Replacement in 10+ Years 

Most heating and cooling equipment is designed to last around 10 to 15 years, but this can be less for businesses with high HVAC demands. If you haven’t had your system replaced in 10 years or more, now is a great time to do so, especially if you’re experiencing any of the above problems.

Reasons to Switch to Commercial Ductless HVAC

Businesses of all sizes need reliable HVAC that’s also efficient and cost-effective. Since ductless units don’t need to push heated or cooled air through a series of ducts to distribute it, they eliminate many of the pitfalls of traditional central systems.

Here are just a few of the reasons New England businesses are making the switch to commercial ductless:

  • Individual zones. If you have different areas of your business that require different temperatures, you can easily do this by setting up multiple zones with a ductless unit in each area.
  • Low operating costs. With a mini-split, heat isn’t generated. It’s just moved around. This makes it incredibly energy efficient, which translates to lower overhead costs for your company.
  • Improved air quality. Your employees and customers can breathe easier indoors with the effective filtration of dust and debris.
  • Easy installation. Having a commercial ductless system installed is fast and easy, with minimal disruption to your day-to-day. It’s also ideal for historic buildings in New England that have regulations on how the building can be modified.
  • Scalable setup. If your company grows in the future, you can add to your existing system without major renovations.
