We used Heritage as we often do for HVAC services. Had a slight gas smell, so the techs checked for a leak. None was found, what we smelled was slight unburned fuel from our water heater (normal operation). s. The technician explained the Rinnai vent is ...pretty close to the porch, code compliant, but out on the porch and the Tankless system fires you’re going to smell some gas exhaust. We also had a water sediment filter and charcoal filter installed for our water supply. The service performed was quality work, everything was explained, and many options offered before we settled on what we chose. I would highly recommend Heritage to anyone needing their services.Read More...

My technician was here on time, very professional and pleasant to work with. He followed all social distancing guidelines and worked quickly. I was just requesting an estimate on repair/replacement of my water heater, but I trust that his feedback was on ...point. I've used Heritage in the past and have been very pleased with their service.Read More...

Had a great experience with Patrick upon our free estimation, so much so that when we decided to go with heritage plumbing and heating for our replacement generator we asked if he could please return to do the project. So he then returned with Eric, the ...technician and his apprentice, Dave, for the propane portion for the project. Everyone was knowledgeable and professional with walking us though the process while also maintaining COVID protocols and procedures. As for the receptionist she was also amazing in connecting us with the right people despite working remotely during a pandemic. The only thing was they needed to be reminded on was coming back to finish up one minor thing... but once contacted about it, a few weeks later, they were here the next day to take care of what had to be done. Overall, great experience and I would highly recommend them to anyone in need of the services they provide; whether it be neighbors, friends, family, or coworkers.Read More...
