How We Size, Select & Design Your System

We start every project with a data-driven design so your new system fits your Norfolk County or Metro West home, not a one-size-fits-all guess.

Our process:

We can perform a Manual J load calculation to estimate your home’s heating and cooling loads and help select properly sized equipment.
We evaluate your ductwork and airflow needs, and when duct design is required, we use Manual D principles to support proper sizing and comfort.
We recommend equipment capacity and efficiency that fit your budget, comfort goals, and the way your home is built.
We review insulation levels and common air leak areas that can impact comfort, sizing, and efficiency.
We talk through your comfort preferences, thermostat habits, and whether zoning or a ductless option makes sense for your home.

On the first visit, we review square footage, number of stories, insulation levels, duct condition, fuel type, electrical panel capacity, and attic or basement access. If you want to be prepared, ask us for a quick first-visit checklist before your estimate.

Installation Process & What to Expect

We run installs on a clear timeline so you know what happens and when.

Typical Project Flow

During the estimate and decision step, we complete an in-home visit, review your options, and provide a clear proposal for next steps.
During scheduling, we confirm equipment availability, review any required approvals, and set your installation date.
Your installation timeline depends on the scope and equipment, and we will provide a clear time estimate during your consultation.

Day-of Install: What You’ll See

When the crew arrives, we confirm equipment placement and walk you through the protection plan for your home.
We protect floors, contain the work area, and keep cleanup ongoing throughout the job.
Installation may include removing old equipment, completing needed duct or piping connections, making electrical hookups, and performing start-up testing and commissioning.
After installation, we walk you through the system operation, help set up the thermostat, and review your paperwork.

Homeowner Prep Checklist

Permits & Inspections

When permits or inspections are required, we will guide you through the process and explain what the town may need for your installation. After completion, we remove job debris, haul away old equipment when applicable, and provide the warranty and maintenance information for your records.

  Top Notch is a life saver - figuratively and literally.  I had them come out as a second opinion to another local company that we previously used.  The previous company came in and gave a bunch of highly-priced options to "fix" an issue they never even diagnosed.  Our gas meter was being replaced unexpectedly, so the other company could not look at anything and instead of coming back later, they guessed on what was wrong based on the system codes that were showing.  They basically scared my wife into doing costly repairs, saying the system would break if they didn't fix it.

We reached out to Top Notch for that 2nd opinion and they came out right away.  The first technician, Vinny, came in very professional and nice, and looked through everything on the system.  Nothing stood out that needed repairs and completed a system maintenance and clean up.  Vinny checked everything - and upon his review he found that our gas vent pipe (that the previous company installed) had disconnected inside the basement.  There was basically carbon monoxide being dumped into our house - who knows for how long.  You would think the previous company would have caught this in their diagnoses - but further nailed down that a 2nd opinion was needed.  This was extremely dangerous and really thankful that Vinny found this out during his inspection of the system.  Goes to show how thorough he was when going through everything.

After Vinny left, we still received the system code on our thermostat.  We called Top Notch again and they sent someone out right away.  This time Aiden came over, who was also very professional and nice.  He spent about 2 hours going through everything again and determined that our gas pressure was running high.  He adjusted the pressure and went on his way.  Top Notch did not charge me for this 2nd visit by their team - which was appreciated.

Unfortunately we got the system code on our thermostat once again, and called Top Notch.  Once more, they sent someone out right away.  This time Sergei arrived and just like the other, was very professional and nice.  He went through and saw the gas pressure was still running high and adjusted further.  Spent some additional time just checking everything and making sure we were all set.  He felt confident that the issue should be set at this point.

Since the last visit, we have not had any issues with the system.  We really appreciated the effort and time that Top Notch put into the care of our system.  And the thoroughness of their inspections really did save us from something that could have been catastrophic with CO2 running into our home.  Thank you again Vinny for finding and fixing this.

I would not hesitate to use Top Notch on any future work in our house.  What we were told were thousands of dollars worth of repairs (or even a new system) that were needed turned out to be a couple hundred dollars worth.  We thank Top Notch for everything they did for us.
