When you are installing a new heating system, it is sized to meet the heating load of your home. If your home becomes less efficient over the years due to air leaks, ailing ducts, failing insulation, or simply increased demand, your furnace is going to be in trouble, and so are your energy bills and comfort.
Read on for a quick lesson on lessening the heating load in your Grand Traverse County home and keep more money in your pocketbook.
Heat gain/loss is a term used to describe the movement of heat into and out of your home. There are many contributing factors to heat gain/loss, including the number and habits of occupants, sun orientation, and the efficiency of your home’s envelope. These are the areas to focus on to lower your home’s load.
Sometimes Less is Better
By lessening your home’s heating load, you can expect the following benefits:
- Your furnace undergoes less wear and may last longer with fewer repairs.
- Your energy bills should be lower.
- You will be more comfortable with fewer drafts and hot/cold spots.
- When you upgrade your furnace, it may be possible to reduce its size and costs.
Tightening Your Home’s Envelope
- Attic: Use expanding spray-in foam and caulk to seal cracks and gaps in the attic. Attic insulation should be free of mold and dampness, and up to R-60.
- Windows: Seal leaky windows with caulk.
- Doors: Check weatherstripping on exterior doors (including sliding glass doors). If it is brittle or leaky, replace it with rubber or silicone weatherstripping. Seal the attic door with foam weatherstripping.
- Ducts: Wrap duct leaks with mastic paste and metal tape. Replace damaged or missing duct sections.
- Basement: Seal cracks and gaps with expanding spray-in foam. Insulate basement walls and beneath flooring with rigid foam board.
- Crawl Space: Seal your unconditioned crawl space with plastic sheeting on the floor and rigid foam board on the walls and under the floor. Affix foam board to vent openings, too.
