Additionally, have your HVAC technician inspect and seal any leaks in your ductwork. Unaddressed duct leaks can result in significant energy loss, leading to higher heating costs and reduced indoor comfort.
Cooling System Preparations
Protecting Outdoor Units from Freezing
While your primary focus may be on heating during the winter, don’t neglect your air conditioning system. Outdoor condensing units are particularly vulnerable to freezing temperatures and can suffer damage if not properly winterised.
Begin by covering or insulating the unit to shield it from wind, snow, and ice. You can also consider installing a protective enclosure or building a small shelter around the outdoor unit to provide an additional layer of insulation and protection.
Air Conditioner Winterisation Procedures
In addition to protecting the outdoor unit, you’ll want to take steps to prepare the internal components of your air conditioning system for the winter. This typically involves draining the system of any remaining coolant or condensate, cleaning the coils and other critical parts, and covering the indoor air handler to prevent dust and debris accumulation.
Following the manufacturer’s recommended winterisation procedures for your specific air conditioning system is crucial to double-check that it emerges unscathed from the winter months.
Alternative Heating and Cooling Options
For some homeowners and businesses, traditional HVAC systems may not be the best fit for their cold-climate needs. In these cases, exploring alternative heating and cooling solutions can be a wise investment.
Geothermal heat pumps, for example, harness the stable temperatures found underground to provide efficient heating and cooling year-round. Hybrid systems that combine a furnace or boiler with a heat pump can also be an effective way to balance heating and cooling needs in regions with extreme seasonal temperature variations.
