Trusted Heating Replacement
We know replacing your home’s heating is a significant investment that should only be in the hands of reputable professionals. If your heating system is inconsistent or no longer responding to repairs, we’ll assess, install, or replace your current unit. Our heating replacement services cover:
- Oil furnaces: Oil furnaces provide powerful and consistent heating. They have a lifespan of around 15 to 20 years and are ideal for homes without access to natural gas.
- Gas furnaces: Known for their lower operating costs, gas furnaces are one of the most popular heating systems.
- Boilers: Boilers heat water and distribute warmth through radiators or baseboard heating. With proper maintenance, they can last 20 to 30 years.
- Heat pumps: Heat pumps are dual heating/cooling units, making them an energy-efficient choice. They’re versatile, convenient, and offer year-round comfort.
Signs You Need Heating Replacement
Our general rule of thumb? If you’re spending more on repairs and heating bills, it’s best to consider a replacement for long-term security. Here are some signs that it may be time to replace your heating:
- Uneven heating: If you’re noticing cold drafts or a lack of warm airflow, your heater may no longer be distributing heat effectively.
- Rising energy bills: Higher-than-average utility costs usually point to an inefficient HVAC system.
- Strange noises or smells: Be aware of a rattling or banging boiler or a furnace emitting gaseous odors.
- Poor indoor air quality: An aging heating system can circulate dust, allergens, and other pollutants, worsening your home’s indoor air quality.
How to Choose the Right Heater for Your Home
Choosing the right heater for your home is a critical decision that impacts long-term comfort and costs. Here are key factors to consider when selecting a heating system:
- Size: An oversized unit is at risk of short-cycling, while an undersized unit will struggle to warm your entire home.
- Budget: Calculate upfront installation costs, maintenance fees, and overall heating bills.
- Efficiency ratings: Look for high AFUE (Annual Fuel Utilization Efficiency) ratings for furnaces and high HSPF (Heating Seasonal Performance Factor) ratings for heat pumps.
- Function: A heat pump is ideal for year-round use, while a boiler or furnace focuses solely on heating.
- Environmental impact: If you’re looking to minimize your home’s carbon footprint, stick to units with high efficiency ratings.
If you’re ready to replace your heater, we’ll work closely with you to select the right model for your home. With our guidance, you’ll feel confident, informed, and equipped to make the best choice.
