How It Works and What to Expect

Installing a packaged HVAC unit doesn’t have to be disruptive or confusing. GEM’s dedicated team will guide you through the process from start to finish, answering any questions you have along the way. Here’s what to expect:

We start with a thorough assessment of your building, existing equipment, and comfort needs to ensure the packaged unit is properly sized and configured. Our team also reviews logistics like roof access, curb requirements, and permits so there are no surprises later.

On installation day, we carefully prepare the site and safely remove your existing unit if one is in place. If you opt for a rooftop installation, we coordinate crane lifts and equipment handling with precision to minimize downtime and disruption to your operations.

Our certified technicians install the new packaged HVAC unit, connect all electrical, gas, and ductwork components, and ensure everything meets code and manufacturer specifications. Every detail is handled with care to support long-term performance and reliability.

Once installation is complete, we thoroughly test the system and fine-tune it for optimal efficiency and comfort. Before we leave, we walk you through system operation, maintenance expectations, and next steps so you feel confident moving forward.

Technician Joseph answered a call for my central air not coming on.
He was experienced and knew what to check out. Also, very friendly. I had central air working in no time at at all!!! Thanks Joseph.
The air conditioner serving the second floor of my brand-new house had problems from day one. For months, the builder kept sending different technicians, each trying to fix one issue after another, but no one addressed the actual cause. As a result, the upstairs bedrooms became unbearably hot, and we often had to sleep in the first\-floor family room just to stay comfortable.

Eventually, instead of waiting any longer for another warranty visit, I called GEM Plumbing & Heating – and I’m so glad I did.

GEM sent a technician, Dory, the very next day. He quickly identified the real problem: a refrigerant leak. It turned out that the builder’s technicians had been treating only the symptoms of the leak, such as condensate buildup, rather than finding and fixing the root cause.

Dory returned the following day with the necessary equipment, and resolved the issue. The air conditioning has been working great ever since.

I only wish I had called GEM from the beginning instead of enduring an uncomfortable summer.

A huge thank you to GEM—and especially to Dory—for real expertise and the outstanding service. Highly recommended!
Michael A. really helped us out by replacing our outdoor outlets, and then turning them all to face the way I needed them to work best for me. He also picked out an excellent flood light for our driveway. Michael was super friendly and efficient. Thank you!!
Two very nice, and helpful young men, came to my home. They were there to do an HVAC summer tuneup. They were quick and efficient. Moreover, they helped me move a couple of things as I am a 100% disabled vet who has had to have three right shoulder replacements..
Mini split water leak was evaluated, repaired and reasonably priced for the job.
Richard & Anthony were very professional and provided complete/honest assessment of HVAC system. Would definitely recommend this service.
Had our electrical outlets repaired and also checked the panel board. The team was professional and explained exactly what they were doing
I willing have all my electrical work done by Gem. Also if needed any plumbing and heating work done also.
I would highly recommend Gem to anyone in need of these services!
Excellent job. Dave is very competent and professional. He’s done work for us in the past and we’re never disappointed.
Joan came out to determine the cause of our AquaCal Pool Heat Pump fault DPO ( defrost sensor code) upon inspection, he found that mice had chewed the wires in three areas. He patched the wires and we are up and running again. The Aquacal company couldn’t be here for over two weeks! GEM has a wonderful team of techs for all your needs. Highly recommended this company for HVAC service. Thank You!
Christopher was professional, pleasant, and efficient.
Came out right away. Fixed the problem. Aggressive upselling!

with excellent communication skills.

Great, efficient, and friendly service. Helped us out in a bind.
Used Gem for electrical issue (installation of 2 ceiling fans). Technicians were very good and job done well and they were able to do it in the time frame I needed which is why they get 5 stars. Price was higher than expected but again, job was done much quicker than from any other electrician

Signs It’s Time to Install a New Packaged Unit

Packaged HVAC units are built to last, but no system runs forever.

If your current unit is struggling to keep up, these warning signs may indicate it’s time for a replacement:

If your utility bills keep climbing without changes in usage, your packaged unit may be losing efficiency. Newer systems are designed to deliver better performance while using less energy.

Needing constant service calls is a sign that your system is reaching the end of its lifespan. Replacing the unit can often be more cost-effective than continuing to repair aging equipment.

Uneven temperatures or trouble maintaining comfort can point to internal wear or failing components. A new packaged unit provides more reliable, consistent heating and cooling throughout your building.

Older units may rely on discontinued parts or refrigerants that are no longer supported. Installing a modern system improves reliability, serviceability, and long-term peace of mind.

If your space has expanded, usage has increased, or occupancy patterns have shifted, your current unit may no longer be properly sized. A new packaged HVAC unit ensures your system matches your building’s current demands.

Benefits of Installing a New Packaged HVAC Unit

Upgrading to a new packaged HVAC unit can make a noticeable difference in comfort, efficiency, and long-term reliability.

Modern systems are designed to meet today’s performance standards while simplifying operation and maintenance.

Some of the many benefits include:

New packaged HVAC units are built with advanced technology that helps reduce energy waste. This translates to lower utility costs and more predictable monthly expenses.

A new system delivers consistent heating and cooling without the breakdowns common in aging equipment. You’ll enjoy dependable comfort during peak seasons when your system matters most.

Packaged units combine heating, cooling, and air handling into a single outdoor system. This frees up valuable indoor space and simplifies your building’s mechanical layout.

With new components and manufacturer warranties, modern packaged units require fewer repairs. Routine maintenance becomes easier and less costly over time.

Today’s systems offer improved airflow, temperature control, and overall performance. The result is a more comfortable environment for employees, customers, and occupants alike.

Frequently Asked Questions About Packaged HVAC Units

Can I install a packaged HVAC unit myself?

Installing these systems is complex and requires the training and tools of an HVAC professional. You can trust GEM’s licensed technicians to handle each step of the process, from preparing the site and placing the unit to connecting ductwork and electrical connections and more.

What does a compressor in a packaged HVAC unit do?

The compressor in your packaged HVAC unit helps pressurize refrigerant and move it through the system to enable the cooling or heating cycle. That’s why it’s known as the “engine” of your HVAC system.

Do packaged HVAC units work well in New England climates?

Yes, modern packaged units are designed to handle a wide range of temperatures and weather conditions. When properly sized and installed, they provide reliable heating and cooling to homes and businesses in Rhode Island and Southeastern Massachusetts.

Will I need permits for a new packaged HVAC unit?

In most cases, yes. GEM handles all required permits and inspections, ensuring your installation meets local codes and manufacturer requirements.
