Frequently Asked Questions

We recommend an annual cleaning and safety inspection. Regular maintenance ensures your system operates at peak efficiency, prevents unexpected mid-winter breakdowns, and validates your manufacturer’s warranty.

While both systems use similar technology to cool your home, a heat pump is a dual-purpose system. It provides high-efficiency cooling in the summer and can reverse the process to provide reliable heating during the colder months.

Most residential furnace installations are completed within a single day. Our goal is to have your heat back up and running as quickly and safely as possible.

Absolutely. We handle the heavy lifting and responsible disposal of your old furnace or oil tank, leaving your home as clean as we found it.

It’s a simple process with Therwood. Contact us for a no-charge estimate; if you decide to move forward, we handle the gas meter application for you. Once the gas company provides the connection cost and you approve, we coordinate the full installation from meter to furnace.

Yes, there are often federal or provincial rebates available for high-efficiency upgrades. Since these programs change frequently, give us a call and we’ll help you identify which current incentives apply to your project.

Yes! If your home currently uses baseboard heaters or a boiler system, we can install a ductless mini-split heat pump. These systems provide efficient heating and cooling to specific rooms without the need for major renovations or duct installation.

For most homes, we recommend changing your filter every 3 months. However, if you have pets or allergies, or if you are running your fan constantly, you should check it monthly. A clean filter is the simplest way to prevent your furnace from overheating and shutting down.

Yes. We provide safety inspections and maintenance for gas and propane fireplaces. Ensuring your fireplace is in good working order provides a vital backup heat source during winter power outages.

Definitely. We can install a whole-home bypass humidifier directly onto your furnace. This automatically manages the moisture levels in your air, protecting your hardwood floors and making your home feel warmer at lower temperatures.
