Bob's Cool Air, Greenfoot Energy Solutions, Bob's Heating & Cooling, EcoTech Refrigeration & HVAC and Andmar Eco-Energy come out on top for HVAC work in Moncton, New Brunswick, ranked here in Google's own order after checking every rating, review count and license claim by hand.
Moncton sits in a humid continental climate with cold, snowy winters and warm, humid summers, which means the average home leans on its heating system for a solid five months a year and increasingly runs a heat pump or central AC through July and August. Greater Moncton's older neighborhoods still have a fair number of oil furnaces waiting to be converted, which is one reason mini-split and ducted heat pump installs dominate the review histories of every company on this list. New Brunswick doesn't run a single province-wide HVAC contractor license the way some provinces do; instead, gas fitting work requires a provincial gas technician certification, and most reputable shops staff Red Seal certified technicians for the mechanical side. Before hiring anyone for a furnace, boiler or gas appliance job, ask to see that certification directly, since it isn't always posted publicly.

Most companies in this ranking work across New Brunswick and the surrounding suburbs. Coverage and travel fees vary, so confirm your address is inside the service area before scheduling.
Moncton
Service coverage across Moncton. Individual company areas are listed on each profile.
Every company here was found through two rounds of Google Maps searches for HVAC contractors in Moncton, then checked one by one: current operating status, a Google rating of at least 4.5 with at least 50 reviews, a real working website matching the Google listing, and a physical or service base inside Moncton rather than a separate town in Greater Moncton. Several strong candidates, including a highly reviewed company based in Riverview, were left off this list because they're headquartered in a separate municipality rather than Moncton itself. Ratings and review counts were checked September 23, 2026. No company paid for placement or review on this list.
How to choose a hvac company in Moncton
Verify insurance and credentials
Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.
Ask for a written estimate
Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.
Compare multiple quotes
Two or three bids on the same scope. A number far below the others usually means something has been left out of it.
Understand the warranty
Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.
Ask who performs the work
Find out whether the crew are employees or subcontractors, and who supervises them on the day.
Check recent local projects
Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.
Avoid high-pressure sales
A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.
Get everything in writing
Change orders, timeline and payment schedule included, before the first payment changes hands.
Questions to ask before hiring
Are you insured, and can you send the certificate?
How long have you worked in this area?
Will you provide a written estimate with materials listed?

Do you use subcontractors for this job?
Who handles permits and inspection?
What would you recommend here, and why?
How are unexpected costs handled once work starts?
What is the estimated timeline from start to finish?

Red flags

Pressure to sign on the first visit
A demand for full payment up front
An offer to cover or waive your insurance deductible
How do I check an HVAC contractor's license in New Brunswick?
New Brunswick doesn't issue a single province-wide HVAC contractor license. Gas fitting work needs a provincial gas technician certification, and most reputable shops staff Red Seal certified mechanical technicians. Ask any company on this list to show current certification before signing a contract, since it's rarely posted with a public number.
How much does a heat pump or furnace cost to maintain in Moncton?
Companies on this list generally recommend an annual maintenance visit, and several offer maintenance plans or service contracts rather than one-off pricing. Ask each company for its specific plan pricing, since none of the five publish flat maintenance rates on their websites, and confirm whether NB Power or federal heat pump rebates apply to your equipment before booking an install.
Why do so many Moncton HVAC companies focus on heat pumps?
A large share of Greater Moncton's housing stock still runs on older oil furnaces, and cold-climate heat pumps rated well below freezing have become the standard upgrade path, helped along by NB Power and federal rebate programs. That's why mini-split and ducted heat pump installs make up most of the review history for every company on this list.
