Choosing an HVAC contractor is not just about who can replace a unit. It is about who understands system design, long-term performance, and how installation quality affects efficiency, comfort, and reliability for years to come.

Dynamic Heating, Cooling & Geothermal was built on hands-on field experience. Before starting the company in 2006, Nathan Noiseux began his career at 17 as an apprentice straight out of trade school. Within a few years, he was leading installations, designing HVAC systems for new homes, and managing field crews. That foundation continues to shape how we approach every project today.

 

From Apprentice to System Designer

Experience in HVAC cannot be learned from a sales manual. It is earned in attics, basements, mechanical rooms, and job sites.

Nathan’s early years were spent installing and designing residential systems, which built a deep understanding of airflow, load calculations, duct design, and system balance. By his mid-twenties, he was designing systems for new construction and leading installation teams.

Later, transitioning into sales revealed something important. Many companies focused heavily on closing deals, but less on long-term system performance and customer relationships. That gap led to the creation of Dynamic Heating, Cooling & Geothermal.

The goal was simple: combine technical expertise with honest service.

 

Residential and Commercial HVAC Expertise

Our experience spans both residential and commercial environments across Connecticut.

On the residential side, we design and install:

  • High-efficiency heat pumps
  • Central air conditioning systems
  • Gas furnaces and hybrid systems
  • Radiant flooring systems
  • Whole-home comfort solutions
 

In commercial settings, our background includes RTU systems, specialty applications, and system upgrades that require coordination, planning, and technical precision. Every environment presents different demands. A residential home requires comfort and energy efficiency. A commercial space requires reliability and operational continuity. Our experience allows us to approach each project with the right technical strategy.

Hugeeee thank you to this company!! With our luck our central air did not want to turn on right before a huge heat wave. We were a little hesitant on reaching out to anyone because some companies tend to take advantage when scenarios like these occur, but Dynamic did not!! My husband called they answered and gave us the first appointment the following morning. That was the first good impression because some companies have you leave voicemails or they do not respond ever. We had a window from 8am-10am, by 8:12am received a text that Alex was on the way, he arrived a little after. He greeted me and introduced himself with a smile. He was very friendly, polite, knowledgeable, and explained everything not only to me, but to my husband on the phone. There were quite a few things needed to get fixed in order to get the central air working, including our thermostat and Alex had it all done very quickly (about 2hrs or so). With the weather getting a little over 100 degrees today we couldn't be any happier and we absolutely grateful for Alex!!!
Have to update this just a little because it is only fair and a MUST to give Isaiah his acknowledgement as well. We had to call Dynamic back to our home on two separate occasions because of a concern and issue. We were very happy to see that they wanted to address things quickly and appointment were provided for the following day. Isaiah was sent out to us for both occasions. He greeted and introduced himself to us with a smile. Isaiah was very polite, nice, knowledgeable and friendly. Both times he arrived ready to address and solve our concerns!!! He took his time to listen and explain everything. Isaiah didn't only leave us the manual for the thermostat we previously purchased from them, but he also set it up so it was ready for the heat and cold. We were were beyond happy/pleased with Isaiah service and expertise!!!
Thanks to Alex, Isaiah and their services, Dynamic is a company that we will definitely contact in the future if needed!!

Huge thanks to ALL at Dynamic Mechanical! Nathan and his team helped us replace one of our 20+ year old geothermal units with ease this summer! They quickly responded and diagnosed our issue when one of our unit decided to meet its demise. His wonderful office team quickly sent several quotes to us, along with options to both save money and quick fix it, as well as quotes to replace the unit(s) entirely. They were also kind enough to send information on financing and rebates, in the event we needed it with the quotes. Nathan was always quick to respond during the process to keep us up to date, even during a record breaking temperature day (104!) when I’m sure he was swamped, that I accidentally called his cell. I cannot recommend Dynamic Mechanical or their team more. Alex & Claudia (our technicians) were wonderfully skilled, kind and respectful. They worked so incredibly hard in our sweltering hot garage all day long for 2 straight days to help our family stay cool and we could not be more grateful or appreciative for their hard work!

Excellent customer service. We have been using Dynamic for years and have never been disappointed with their service. We just had Alex for service and he was GREAT!! He arrived on time, was very friendly, and was very conscientious of being careful because we have 2 indoor cats. Great Job.

 

Geothermal and High-Efficiency System Specialists

 

Geothermal and high-efficiency heat pump systems require more than basic installation knowledge. They demand proper design, accurate sizing, and a clear understanding of how systems interact with the building envelope.

Dynamic Heating, Cooling & Geothermal has built a strong focus on environmentally sound HVAC solutions. We work with geothermal systems, advanced heat pumps, and high-efficiency equipment designed to reduce long-term energy consumption while maintaining consistent comfort.

These systems are not one-size-fits-all. Proper installation determines whether a homeowner experiences long-term efficiency or ongoing performance issues. Our field experience ensures systems are designed and installed correctly from the start.

 

How Experience Impacts System Performance

HVAC equipment is only as good as the installation behind it.

Improper sizing, poor duct design, incorrect refrigerant charging, or rushed installation can reduce efficiency, increase wear, and shorten equipment lifespan. Many comfort complaints are not product failures. They are installation failures.

Our experience allows us to:

  • Perform accurate load calculations
  • Design systems tailored to the home or facility
  • Ensure proper airflow and balance
  • Install equipment according to the manufacturer’s specifications
 

When systems are installed correctly, they operate more efficiently, last longer, and require fewer corrective service calls.

 

Built on Integrity, Not Sales Pressure

After working in sales and seeing the industry from both the field and the office, Nathan recognized the need for a different approach.

Dynamic Heating, Cooling & Geothermal was founded on long-term relationships rather than one-time transactions. Our focus is not simply on replacing equipment. It is on designing systems that meet the client’s needs and standing behind the work after installation.

For over 19 years, our company has operated on honesty, professionalism, and consistent service. We continue to invest in training and technology to stay current with HVAC advancements, including geothermal systems and high-efficiency heat pumps. We are proud to remain family-owned and operated, serving Connecticut homeowners and businesses with accountability and care.
