Fast, Dependable Gas Hot Water for Metro West Homes

Top Notch HVAC Company installs gas water heaters for homeowners throughout Norfolk County and the Metro West area. Gas units heat water faster than standard electric models and typically cost less to operate over time, which is why they’re the most common choice in homes already connected to natural gas or propane. Family-owned since 2014 and licensed to work on gas appliances in Massachusetts, we handle every part of the job: sizing, venting, gas line connections, and any code-required inspections. Nothing gets subcontracted out or skipped. We install natural gas and propane tank water heaters from top brands including Rheem, Bradford White, and AO Smith. Venting configurations include direct vent, power vent, and atmospheric depending on your home’s layout and existing flue setup. We assess the right approach for your specific home before we quote the job, so there are no surprises on installation day. Most gas water heater installations are completed within a few hours, and we haul away the old unit as part of the job.

Older gas water heaters lose efficiency as sediment accumulates in the tank and components wear with age. If your unit takes noticeably longer to recover between showers, produces rust-colored water, makes a popping or rumbling sound during heating cycles, or is approaching 10 years in service, it’s worth getting a professional look before it fails at an inconvenient time. We serve Medway, Milford, Franklin, Bellingham, Walpole, Norwood, Needham, and surrounding communities throughout Norfolk County and Metro West.

We stock the most common replacement parts and carry them on every service truck, so most gas water heater repairs happen in a single visit. Check out our water filtration services if you want to address water quality concerns at the same time as your water heater replacement.

Why Choose Top Notch HVAC Company

Natural Gas Tank Water Heater Installation

Natural gas tank water heaters are the most widely installed type in homes across Norfolk County and Metro West. They recover quickly between back-to-back showers, handle high hot water demand without issue, and are available in sizes from 30 to 75 gallons to fit any household. We install units from leading brands and handle all venting work to Massachusetts code: direct vent, power vent, or atmospheric, matched to your home’s existing flue configuration. We inspect and confirm the gas line connection is safe before we leave the job.

Propane Water Heater Installation

For homes in rural parts of Metro West and Norfolk County without access to a municipal gas line, propane water heaters are a high-performance alternative. Propane burns at a higher heat content per BTU than natural gas, giving propane units a fast first-hour recovery rate well suited to high-demand households. We install and service propane tank water heaters and can help you coordinate with your propane supplier on tank sizing and fuel delivery setup if you’re starting a new system from scratch.

Gas Water Heater Repair & Replacement

We service all brands of gas water heaters throughout the Metro West area. The most common repair calls involve pilot light failures, worn thermocouples, burner assembly fouling, sediment buildup slowing recovery time, and pressure relief valve issues. If your unit is leaking from the tank body itself rather than a connection or fitting, replacement is the only real fix. A tank body leak means the steel wall has corroded through and repairs will not hold long-term. We carry common parts on every truck and most jobs complete in a single visit. New installation discount available on qualifying replacements.

  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.
