A cold-climate heat pump is the modern standard for home comfort, delivering precise air conditioning in the summer and reliable, high-efficiency heating in the winter. At Twintech Heating & Cooling, twin brothers Greg and Grant Dainty specialize in advanced heat pump retrofits across Pickering, Ajax, Whitby, Oshawa, Bowmanville, Scarborough, and Markham. As third-generation HVAC professionals, we don't use high-pressure sales pitches — just honest system design and perfect technical setup to optimize your home comfort year-round.
Replace your old, expensive heating and cooling equipment with a single smart system. We design custom heat pump configurations tailored specifically to your home’s architectural limits, electrical load capacity, and budget.
Is your heat pump short-cycling, running constantly, or showing an unfamiliar error code? Our licensed technicians carry factory-stocked service trucks to quickly fix refrigeration issues, replace failing components, and perform seasonal tune-ups to protect your manufacturing warranty.
Discover how a modern heat pump system can eliminate your reliance on fossil fuels and cut your monthly utility bills. Contact Twintech today.
Unlike a gas furnace that burns fossil fuels to create heat, a heat pump simply moves existing heat from one place to another.
Switching to an all-in-one heat pump or servicing your existing system can bring up a lot of questions. To help you navigate your year-round home comfort options, Greg, Grant, and the Twintech team have put together straightforward answers to the most common questions homeowners ask us about heat pump installation, cold-weather performance, and active utility rebates.
Yes, absolutely. Modern cold-climate heat pumps are engineered specifically for our harsh Canadian environment and can reliably pull heat from the outside air in temperatures as low as -30°C. For total peace of mind, we can set up a hybrid system that uses your existing furnace as an automated backup only on the single coldest days of the year.
Yes, there are frequently high-value government and utility rebates available to Ontario homeowners who upgrade to high-efficiency, cold-climate heat pump systems. Because active programs change, contact our office directly and we will lay out the current rebate rules and handle the diagnostic alignment for you.
A central heat pump hooks directly into your home’s pre-existing furnace duct network to deliver balanced heating and cooling through your standard registers. A ductless mini-split system uses compact, wall-mounted air handlers positioned in specific rooms, making it the perfect choice for home additions or older properties without existing duct paths.
An air-source heat pump relies on advanced electrical architecture to transfer heat efficiently. Applying for an official electrical permit is not an optional shortcut; it is a critical safety baseline required to ensure your home’s main panel can handle the load safely and protect your property’s structural insurance coverage.
