What Customers Say

“Just had a heat pump installed. Matt and crew did a great job. Their price was favourable compared to other estimates we received but they seemed much more knowledgeable and prepared than the competitors we talked to. We also have a gas fireplace maintenance plan with M&K. They are very responsive when our tenants have called for service and have always been a pleasure to deal with.”

- Lori M.

“Absolutely no complaints, head office communicates well and the tech was professional (and quite safe for corona time) and explaining our options well.”

- Peter B.

Frequently Asked Questions

Heat pumps move heat around your home and can help fix uneven temperature zones, such as hot or cold spots. Heat pumps also use less energy, and when the weather is mild, they can work in place of a furnace or air conditioner, reducing wear and tear on these units.

Heat pumps are around the same size as an air conditioner, but their sizes may vary a bit depending on the type of heat pump you need. Our trained technicians will assess your home to ensure you have a space suitable for a heat pump. Appropriate areas need to be well-ventilated and beside an external wall.

The size of heat pump required to meet your needs depends on several factors, including the size of your home. Book a free consultation to find out exactly what kind of heat pump your home needs.

Depending on the size and type of heat pump required, installation usually takes between 4 and 6 hours, but the timeframe may vary. Our experts will be able to provide you with a detailed estimate during your in-home assessment.

As with most major appliances, heat pumps require regular maintenance to keep them running smoothly. Regular check-ups can catch any issues before they progress and give your technician the chance to make any necessary adjustments.
