When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

We called several plumbers and I got “we are too busy” and “it’s too small of a job”. Not with heritage though! They were able to get us on the schedule in a timely manner and helped us with our plumbing issue. Thank you Zach! Zach was quick and professional! Will definitely use again!

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!

Frequently Asked Questions

  • What are the benefits of a tankless water heater?

    Tankless water heaters heat water on demand, so you never run out during heavy usage. They are more energy efficient because they only heat water when needed, take up less space, and typically last 20 years or more compared to 8 to 12 years for traditional tank heaters.

  • Can my Maine home switch from a tank to a tankless water heater?

    In most cases, yes. Heritage can retrofit your home for a tankless water heater. The installation may require upgrades to your gas line, venting, or electrical supply. Our licensed plumbers assess your home and explain what is needed before work begins.

  • How long does a tankless water heater last?

    Tankless water heaters typically last 20 years or more with proper maintenance, significantly longer than traditional tank models. Regular descaling and filter cleaning help maximize efficiency and lifespan.

  • Does Heritage service and repair tankless water heaters in Maine?

    Yes. Heritage provides complete tankless water heater services including installation, maintenance, descaling, and repair. Whether your unit is not producing hot water, showing an error code, or due for maintenance, our licensed plumbers can help.

  • What size tankless water heater does my home need?

    The right size depends on the number of fixtures and appliances that may use hot water simultaneously and the groundwater temperature in your area. Maine’s cold groundwater temperatures require a more powerful unit than warmer climates. Heritage will calculate your demand and recommend the correct size.
