Winter in Maine demands a heating system you can depend on.

If your furnace, boiler, or heat pump is nearing the end of its service life, now is the ideal time to invest in a high-efficiency replacement. Upgrading before the heating season means greater comfort, improved energy efficiency, enhanced reliability, and the confidence that your home will be ready when temperatures drop.

At Perreault Mechanical, we believe every installation should be done right the first time. From expert system design to meticulous installation, we deliver heating solutions built for long-term performance—not quick fixes.

As colder weather approaches, installation schedules fill quickly. Secure your replacement now and enjoy the comfort of knowing your home is prepared for whatever winter brings.

Schedule your complimentary in-home consultation today and experience the difference that quality craftsmanship makes.

Code Reminder – Venting Materials in Maine

We came across a system today that was vented using IPEX System 636.

Please note that UL 1738 and System 636 venting materials are not approved for venting under the Maine plumbing/ fuel code. Always verify that the venting material being installed is approved by both the appliance manufacturer and the codes adopted in Maine. Maine currently enforces the 2021 Uniform Plumbing Code with state-specific amendments. (Maine⁠)

Additionally, all solvent-welded vent piping in Maine must be installed using a contrasting primer and cement. Clear primer or clear/UV cement does not meet Maine code requirements. Be sure the primer remains visibly distinguishable from the cement for inspection purposes. (Maine⁠)

Taking a few extra minutes to verify approved vent materials and use the proper primer and cement can help prevent failed inspections and ensure a safe, code-compliant installation.

Annual maintenance is crucial, as evidenced by our discovery of a cracked heat exchanger on an Empire space heater. This defect was causing Carbon Monoxide to enter the living space, and regular checks would have detected the issue before it became a hazard.

As extreme low temperatures approach, we underscore the importance of regular system maintenance. A well-maintained and clean system will operate efficiently and reliably withstand the strain of prolonged cold weather. The boiler in question had not been cleaned for a considerable period, causing it to emit soot and black smoke throughout the customer’s home.
