About The Hayter Group

The Hayter Group is a Southwestern Ontario contractor based at 3277 Nauvoo Rd in Alvinston, Ontario. Since 1952 we have designed and installed geothermal, solar, heating and cooling, plumbing, and electrical systems for homes and businesses across the region.

In 2025 the company joined the Jayden's Mechanical family. The Hayter name, the Alvinston shop, and the licensed crews all continue, now backed by a wider group for parts, crews, and financing. For longtime customers, almost nothing changes day to day except the depth behind the work.

How we work

From first call to long-term comfort

The same licensed crew that evaluates your home is the crew that designs, installs, and services it. One accountable team, end to end.

01 Evaluate A free on-site or virtual look at your home, your current system, and your goals. We tell you honestly what makes sense.

02 Design We size the system to your real load, map every rebate it qualifies for, and hand you the numbers before any work starts.

03 Install Licensed crews install to code, pull the permits, and complete the rebate paperwork so the incentive reaches you without the chase.

04 Service Annual maintenance and 24-hour emergency support, year after year, from the same shop that did the install.

The Hayter flagship

Geothermal that pays for itself

A geothermal heat pump moves heat from the ground, delivering about five units of energy for every one unit of electricity it uses. That is roughly 500% efficiency, and most homeowners cut their heating, cooling, and hot-water costs by around 70%.

Explore Geothermal

A geothermal heat pump runs at roughly 500% efficiency, moving about five units of heat for every one unit of electricity, with no combustion, no on-site emissions, and an indoor unit that runs quietly year-round.

Most homeowners cut heating, cooling, and hot-water costs by around 70%.

With current provincial rebates and interest-free financing, the payback on a system often lands inside three to five years for the right property. We size the loop, run the savings math, and handle the paperwork.

Rebates & financing

Geothermal, solar, and heat-pump projects qualify for thousands in provincial and federal support. We handle the paperwork so the rebate is straightforward.

A new chapter

Seventy years of Hayter,
now part of a wider family.

In 2025, The Hayter Group joined the Jayden's Mechanical family. Here is what that means for the customers who have trusted us for 74 years.

For you, almost nothing changes day to day. The Hayter name stays. The Alvinston shop stays. The licensed crews who know the region stay. What is new is the backing: a larger Southwestern Ontario group means more crew for peak-season and emergency calls, access to more equipment brands, and the depth to take on anything from a single repair to a full geothermal retrofit.

The same shop. The same standard. More depth behind it.

If you have called us before, your experience carries on unchanged. If you are new to Hayter, you get a seventy-year local contractor with the reach of a larger group.
