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.
This behavior often points to a heavily clogged system air filter choking airflow, deep layers of dirt insulating the outdoor coil fins, or a slow refrigerant leak. Because the heat pump cannot transfer heat properly, it works overtime to compensate, driving up your hydro costs and putting unnecessary strain on the compressor.
Because a heat pump handles both your summer air conditioning and your winter heating, it runs nearly all year long. We highly recommend scheduling professional maintenance twice a year — once in the spring before the cooling season hits, and once in the autumn to optimize your heating efficiency ahead of the deep freeze.
A thin, even layer of frost is normal during a winter cycle, and the heat pump will automatically run its built-in defrost cycle to melt it away. However, if the unit becomes completely encased in thick ice, it usually indicates a broken defrost control board, a faulty sensor, or a failed fan motor that requires immediate diagnostic repair.
We make the incentive process completely evergreen and stress-free. Our office continuously tracks active utility and provincial efficiency programs. We verify your heat pump’s eligibility requirements upfront, collect all matching documentation, and assist with your final submissions so you don’t have to handle the administrative hassle alone.
