Heat recovery ventilators
A heat recovery ventilator exchanges air inside your home with fresh outdoor air. It can also help lower your energy bills.
Sealing ductwork
Leaky ductwork is one of the most common household problems. Luckily, it's easy to fix with the right materials.
Leaky ducts allow air from your heating and cooling system to escape before reaching your rooms. These leaks not only waste energy, but can also create air quality issues. Properly sealing your ductwork can increase your home’s energy efficiency, lower your energy bills and increase your air quality.
You can seal your ductwork yourself using metal and foil-reinforced tape or mastic, which is a fiber-reinforced paste. Alternatively, a professional can use aerosol sealants to seal the ductwork internally. Tip: remember to leave your furnace filter slot or the combustion air inlets in your HVAC system open and unsealed.
