High efficiency furnaces can use less fuel to produce the same amount of heat, resulting in lower energy consumption and reduced costs.
Often referred to as a combi boiler, this highly efficient heating system provides both hot water and space heating from a single unit.
A condensing boiler recovers and reuses heat from combustion gases, reducing fuel consumption and increasing efficiency.
This equipment saves energy by circulating water from the main boiler through a heat exchanger in a storage tank, reducing usage.
Ensure the health of your gas furnace or boiler with a tune-up to optimize performance, improve efficiency, and prevent potential issues.
This device automatically controls the boiler water temperature based on outdoor weather so the heating system runs efficiently.
This smart device adapts to your preferences and optimizes heating & cooling efficiency, providing personalized comfort & savings.
ERVs & HRVs improve indoor air quality, save energy, and defend against allergens by replacing stale indoor air with fresh air.
Check your equipment’s average life span to see if it may be overdue for an upgrade
To see if now is a good time to upgrade your system, check the average lifespan of your current heating system in the chart below. On average, most heating systems last between 15 and 35 years depending on the type.
Use this chart to see if you should upgrade your water heater, furnace, or boiler to a high-efficiency model.
| Type of Equipment | Average Effective Unit Life Span (Years) |
|---|---|
| Water Heater | 10-15 |
| Combination Boiler-Furnace | 20 |
| Furnace (Gas) | 22 |
| Steam Boiler (Steel Fire Tube) | 25 |
| Steam Boiler (Cast Iron or Steel Water Tube) | 30 |
| Hot Water Boiler | 35 |
