“The heat pump install took two days. Floors were covered, the old unit was hauled away, and the technician walked me through the readings before he left. They handed us everything the rebate application needed.”

“Been on the twice-a-year plan since 2019. They catch things in October that would have been a January emergency. The reading sheet they leave actually gets compared year to year.”

Yes. Cold-climate heat pumps are designed for Canadian winters, and certain models can operate at temperatures as low as -30°C. Performance varies by model, so we recommend equipment and backup heating suited to your property.
The customer submits the application. JCD provides the invoice, equipment information and supporting installation documents. Our team can help you understand which documents to include.
We recommend servicing air conditioning once a year in spring, before summer, and heating equipment once a year before winter. For heat pumps that provide both heating and cooling, seasonal visits help prepare the system for each period of use.
