When it comes to staying warm during the Lakewood winters, your furnace plays a critical role in keeping your home comfortable and safe. Whether you’re replacingĀ or installing a new furnace, choosing the right furnace is a big decision—and the team at True Flow Heating and Air is here to help you make the best choice for your space, budget, and long-term comfort.

1. Understand the Different Types of Furnaces

Furnaces come in various fuel types, with gas, electric, and oil being the most common. In Colorado, natural gas is typically the most cost-effective option due to its availability and efficiency. However, electric furnaces may be a better fit for homes without gas lines, offering a cleaner installation with lower upfront costs.

Every home is different, so it’s important to choose a system that fits your setup and energy goals. True Flow Heating and Air can walk you through each option to help you find the best fit.

2. Consider Furnace Efficiency Ratings

The Annual Fuel Utilization Efficiency (AFUE) rating measures how efficiently a furnace converts fuel into heat. A higher AFUE means more energy savings over time. Older furnaces might operate at 60–70% efficiency, while modern units can reach up to 98%. Investing in a high-efficiency furnace can significantly reduce your energy bills and your carbon footprint.

If you’re unsure where to start, our team can evaluate your home and recommend systems that offer the best balance of performance and efficiency for your lifestyle.

3. Size Matters: Don’t Over- or Underestimate

A furnace that’s too large will cycle on and off too frequently, leading to uneven temperatures and wasted energy. A unit that’s too small will struggle to heat your home on the coldest days. At True Flow Heating and Air, we provide expert load calculations to determine the proper furnace size based on your home’s square footage, insulation, and more.

4. Choose a Trusted Installation Team

Even the best furnace won’t perform well if it’s installed incorrectly. Our certified technicians at True Flow Heating and Air have been helping Lakewood and Douglas County homeowners since 2018, ensuring each installation is done right the first time. We prioritize customer comfort, honest service, and expert craftsmanship in everything we do.

5. Plan for the Long Term

When selecting a furnace, don’t just think about this winter—think about the next 15 to 20 years. Consider maintenance needs, warranties, and available features like smart thermostats or variable-speed motors that can enhance comfort and control.
