  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.
